• Linux实战教学笔记51:Zabbix监控平台3.2.4(三)生产环境案例


    一,Zabbix生产环境监测案例概述

    1.1 项目规划

    • [x] :主机分组
      • 交换机
      • Nginx
      • Tomcat
      • MySQL
      • Apache
      • PHP-fpm
      • redis(也有状态页,同学们自己研究)
      • memcache(也有状态页,同学们自己研究)
    • [x] :监控对象识别:
      • 使用SNMP监控交换
      • 使用IPMI监控服务器硬件
      • 使用Agent监控服务器
      • 使用JMX监控JAVA
      • 监控MySQL
      • 监控Web状态
      • 监控Nginx状态
      • 监控Apache状态
      • 监控Tomcat状态

    1.2 SNMP监控流程

    1. 交换机上开启snmp
    2. 在zabbix上添加监控(设置SNMP interfaces)
    3. 关联监控模版

    1.3 IPMI

    建议使用自定义item监控服务器硬件,在本地执行ipmitool命令来获取数据

    可以在本地执行ipmitool命令获取数据(命令需要安装)

    1.4 JMX(使用Zabbix Java Gateway代理)

    用来获取java数据,本次的实战内容

    1.5 实战监控Nginx,Apache,MySQL,PHP-fpm

    今天的实战内容,请同学们注意总结过程

    1.6 Zabbix的Web监测

    今天的实战内容,请同学们注意总结过程

    二,Zabbix监控MySQL数据库操作实战

    我们需要部署一个MySQL服务和一个zabbix-agentd客户端

    2.1 编写监控脚本

    在nginx服务器(192.168.0.221)上安装一个MySQL
    下面是监控mysql状态的一个shell脚本,内容如下:

    [root@nginx scripts]# pwd
    /server/scripts
    [root@nginx scripts]# cat check_mysql.sh 
    #!/bin/bash
    # author:Mr.chen
    
    MySQL_USER="root"
    MySQL_PWD="123123"
    MySQL_HOST="127.0.0.1"
    MySQL_PORT="3306"
    
    MySQL_CONN="/usr/local/mysql/bin/mysqladmin -u${MySQL_USER} -h${MySQL_HOST} -P${MySQL_PORT} -p${MySQL_PWD}"
    
    if [ $# -ne "1" ];then
        echo "arg error!"
    fi
    
    case $1 in
        Uptime)
            result=`${MySQL_CONN} status | cut -f2 -d":" | cut -f1 -d "T"`
            echo $result
            ;;
        Com_update)
            result=`${MySQL_CONN} extended-status | grep -w "Com_update" | cut -d"|" -f3`
            echo $result
            ;;
        Slow_querles)
            result=`${MySQL_CONN} status | cut -f5 -d":" | cut -f1 -d"O"`
            echo $result
            ;;
        Com_select)
            result=`${MySQL_CONN} extended-status | grep -w "Com_select" | cut -d "|" -f3`
            echo $result
            ;;
        Com_rollback)
            result=`${MySQL_CONN} extended-status | grep -w "Com_rollback" | cut -d"|" -f3`
            echo $result
            ;;
        Questions)
            result=`${MySQL_CONN} status | cut -f4 -d":" | cut -f1 -d"S"`
            echo $result
            ;;
        Com_insert)
            result=`${MySQL_CONN} extended-status | grep -w "Com_insert" | cut -d"|" -f3`
            echo $result
            ;;
        Com_delete)
            result=`${MySQL_CONN} extended-status | grep -w "Com_delete" | cut -d"|" -f3`
            echo $result
            ;;
        Com_commit)
            result=`${MySQL_CONN} extended-status | grep -w "Com_commit" | cut -d"|" -f3`
            echo $result
            ;;
        Bytes_sent)
            result=`${MySQL_CONN} extended-status | grep -w "Bytes_sent" | cut -d"|" -f3`
            echo $result
            ;;
        Bytes_received)
            result=`${MySQL_CONN} extended-status | grep -w "Bytes_received" | cut -d"|" -f3`
            echo $result
            ;;
        Com_begin)
            result=`${MySQL_CONN} extended-status | grep -w "Com_begin" | cut -d"|" -f3`
            echo $result
            ;;
        *)
            echo "Usage:$0(Uptime|Com_update|Slow_querles|Com_rollback|Questions|Com_insert|Com_delete|Com_commit|Bytes_sent|Bytes_received|Com_begin)"
            ;;
    esac
    

    2.2 在zabbix-agent端创建自定义键值配置文件

    #创建mysql.status的键值
    [root@nginx scripts]# chmod +x check_mysql.sh 
    [root@nginx scripts]# chown zabbix.zabbix check_mysql.sh
    [root@nginx zabbix]# cd /etc/zabbix/zabbix_agentd.d/
    [root@nginx zabbix_agentd.d]# cat mysql_status.conf 
    UserParameter=mysql.status[*],/server/scripts/check_mysql.sh $1
    
    #删除旧键值模版
    [root@nginx zabbix_agentd.d]# rm -rf userparameter_mysql.conf 
    
    #创建mysql.ping和mysql.version的键值
    [root@nginx zabbix_agentd.d]# cat mysql_status.conf 
    UserParameter=mysql.status[*],/server/scripts/check_mysql.sh $1
    UserParameter=mysql.ping,/usr/local/mysql/bin/mysqladmin -uroot -p123123 ping | grep -c alive
    UserParameter=mysql.version,/usr/local/bin/mysql -V
    
    #重启zabbix-agentd服务
    [root@nginx zabbix_agentd.d]# /etc/init.d/zabbix-agent restart
    Shutting down Zabbix agent:                                [  OK  ]
    Starting Zabbix agent:                                     [  OK  ]
    

    2.3 在zabbix-server端测试键值

    [root@Zabbix_Server scripts]# zabbix_get -s 192.168.0.221 -p 10050 -k "mysql.status[Uptime]"
    2791
    [root@Zabbix_Server scripts]# zabbix_get -s 192.168.0.221 -p 10050 -k "mysql.status[Com_commit]"
    0
    [root@Zabbix_Server scripts]# zabbix_get -s 192.168.0.221 -p 10050 -k "mysql.status[Bytes_sent]"
    144628
    [root@Zabbix_Server scripts]# zabbix_get -s 192.168.0.221 -p 10050 -k "mysql.status[Bytes_received]"
    3934
    [root@Zabbix_Server scripts]# zabbix_get -s 192.168.0.221 -p 10050 -k "mysql.ping"
    1
    [root@Zabbix_Server scripts]# zabbix_get -s 192.168.0.221 -p 10050 -k "mysql.version"
    /usr/local/bin/mysql  Ver 14.14 Distrib 5.5.32, for linux2.6 (x86_64) using readline 5.1
    

    2.4 在zabbix-server端Web前台引入zabbix监控MySQL的模版

    zabbix自带监控MySQL的模版,我们只需要将模版引入到主机即可
    配置-->主机-->选择主机-->模板,然后将MySQL模版连接到此主机即可

    QQ截图20180122210222.png-42.2kB

    QQ截图20180122210235.png-25.5kB

    QQ截图20180122210257.png-20.8kB

    QQ截图20180122210610.png-36.3kB

    QQ截图20180122210625.png-88kB

    从图中可以发现模版里的键值都是我们之前已经定义好了的键值。

    三,Zabbix监控Apache、Nginx操作实战

    3.1 实战监控Apache

    3.1.1 源码编译构建apache服务

    #为了避免冲突,若系统中已经安装httpd服务,务必删除
    [root@apache ~]# rpm -q httpd
    package httpd is not installed
    [root@apache ~]# /etc/init.d/iptables stop
    [root@apache ~]# setenforce 0
    setenforce: SELinux is disabled
    
    #源码构建apache
    [root@apache httpd-2.2.17]# tar xf httpd-2.2.17.tar.gz -C /usr/src/
    [root@apache httpd-2.2.17]# cd /usr/src/httpd-2.2.17/
    [root@apache httpd-2.2.17]# ./configure --prefix=/usr/local/httpd --enable-so --enable-rewrite --enable-charset-lite --enable-cgi && make && make install
    [root@apache httpd-2.2.17]# cd /usr/local/httpd/
    [root@apache httpd]# ls
    bin  build  cgi-bin  conf  error  htdocs  icons  include  lib  logs  man  manual  modules
    [root@apache httpd]# ln -s /usr/local/httpd/bin/* /usr/local/bin/
    [root@apache httpd]# cp /usr/local/httpd/bin/apachectl /etc/init.d/httpd
    [root@apache httpd]# chmod +x /etc/init.d/httpd
    [root@apache ~]# cd /usr/local/httpd/htdocs/
    [root@apache htdocs]# echo "`hostname -I` I am apache" > index.html
    [root@apache htdocs]# cat index.html 
    192.168.0.222  I am apache
    [root@apache conf]# awk '/#ServerName/{print NR,$0}' httpd.conf 
    97 #ServerName www.example.com:80
    [root@apache conf]# sed -i -e '97 s/#//;s/example/yunjisuan/' httpd.conf 
    [root@apache conf]# sed -n '97p' httpd.conf 
    ServerName www.yunjisuan.com:80
    [root@apache conf]# /etc/init.d/httpd start
    [root@apache conf]# netstat -antup | grep httpd
    tcp        0      0 :::80                       :::*                        LISTEN      53288/httpd         
    [root@apache conf]# echo "`hostname -I` www.yunjisuan.com" >> /etc/hosts
    [root@apache conf]# tail -1 /etc/hosts
    192.168.0.222  www.yunjisuan.com
    [root@apache conf]# curl www.yunjisuan.com
    192.168.0.222  I am apache
    

    3.1.2 开启apache状态页

    要打开apache的ServerStatus页面,需要在httpd.conf文件最下边加入代码段

    ExtendedStatus On
    <location /server-status>
    SetHandler server-status
    Order Deny,Allow
    Deny from all
    Allow from 127.0.0.1
    </location>

    最后,重启动apache即可

    3.1.3 下载apache zabbix模版并解压

    #从如下地址下载apache zabbix模版:
    [root@apache ~]# wget https://github.com/lorf/zapache/archive/master.zip
    #解压zip格式压缩文件
    [root@apache ~]# unzip master
    [root@apache ~]# ls -d zapache-master
    zapache-master
    [root@apache ~]# cd zapache-master/
    [root@apache ~]# tree zapache-master/
    zapache-master/
    ├── httpd-server-status.conf.sample
    ├── README.md
    ├── userparameter_zapache.conf.sample
    ├── zapache
    ├── zapache-template-active.xml
    └── zapache-template.xml
    
    0 directories, 6 files
    
    • 此模版文件中包含了监控apache的脚本文件,zabbix的apache模版文件,还有客户端zabbix自定义传key文件。
    • 首先将zapache放到需要监控的apache服务器上的/etc/zabbix/scripts目录下,如果没有scripts目录,自行创建一个即可。然后执行授权:
    [root@apache zapache-master]# chmod 755 /etc/zabbix/scripts/zapache
    [root@apache scripts]# cd /etc/zabbix/scripts/
    [root@apache scripts]# ./zapache 
    zapache version: 1.5
    usage:
      ./zapache [<url>] TotalAccesses                 - Check total accesses.
      ./zapache [<url>] TotalKBytes                   - Check total KBytes.
      ./zapache [<url>] CPULoad                       - Check CPU load.

      ./zapache [<url>] BytesPerReq                   - Check Bytes per request.
      ./zapache [<url>] BusyWorkers                   - Check busy workers.
      ./zapache [<url>] IdleWorkers                   - Check idle workers.
      ./zapache [<url>] version                       - Version of this script.
      ./zapache [<url>] ping                          - Check if Apache is up.
      ./zapache [<url>] WaitingForConnection          - Check Waiting for Connection processess.
      ./zapache [<url>] StartingUp                    - Check Starting Up processess.
      ./zapache [<url>] ReadingRequest                - Check Reading Request processess.
      ./zapache [<url>] SendingReply                  - Check Sending Reply processess.

      ./zapache [<url>] GracefullyFinishing           - Check Gracefully Finishing Processess.
      ./zapache [<url>] IdleCleanupOfWorker           - Check Idle Cleanup of Worker Processess.
      ./zapache [<url>] OpenSlotWithNoCurrentProcess  - Check Open Slots with No Current Process.
    
    • 接着将userparameter_zapache.conf.sample文件放到/etc/zabbix/zabbix_agentd.d目录下,并重命名为userparameter_zapache.conf文件,然后修改键值命令的路径。
    • 最后,重启zabbix-agent服务
    [root@apache zapache-master]# mv userparameter_zapache.conf.sample /etc/zabbix/zabbix_agentd.d/userparameter_zapache.conf
    [root@apache zabbix_agentd.d]# tail -1 userparameter_zapache.conf 
    UserParameter=zapache[*],/etc/zabbix/scripts/zapache $1    #本行要修改
    [root@apache zapache-master]# /etc/init.d/zabbix-agent restart
    Shutting down Zabbix agent:                                [  OK  ]
    Starting Zabbix agent:                                     [  OK  ]

    3.1.4 测试键值

    #在zabbix-agent端查看脚本用法
    [root@apache zabbix_agentd.d]# cd /etc/zabbix/scripts/
    [root@apache scripts]# ./zapache 
    zapache version: 1.5
    usage:
      ./zapache [<url>] TotalAccesses                 - Check total accesses.
      ./zapache [<url>] TotalKBytes                   - Check total KBytes.
      ./zapache [<url>] CPULoad                       - Check CPU load.
      ./zapache [<url>] Uptime                        - Check uptime.
      ./zapache [<url>] ReqPerSec                     - Check requests per second.
      ./zapache [<url>] BytesPerSec                   - Check Bytes per second.
      ./zapache [<url>] BytesPerReq                   - Check Bytes per request.
      ./zapache [<url>] BusyWorkers                   - Check busy workers.
      ./zapache [<url>] IdleWorkers                   - Check idle workers.
      ./zapache [<url>] version                       - Version of this script.
      ./zapache [<url>] ping                          - Check if Apache is up.
      ./zapache [<url>] WaitingForConnection          - Check Waiting for Connection processess.
      ./zapache [<url>] StartingUp                    - Check Starting Up processess.
      ./zapache [<url>] ReadingRequest                - Check Reading Request processess.
      ./zapache [<url>] SendingReply                  - Check Sending Reply processess.
      ./zapache [<url>] KeepAlive                     - Check KeepAlive Processess.
      ./zapache [<url>] DNSLookup                     - Check DNSLookup Processess.

      ./zapache [<url>] Logging                       - Check Logging Processess.
      ./zapache [<url>] GracefullyFinishing           - Check Gracefully Finishing Processess.
      ./zapache [<url>] IdleCleanupOfWorker           - Check Idle Cleanup of Worker Processess.
      ./zapache [<url>] OpenSlotWithNoCurrentProcess  - Check Open Slots with No Current Process.
    

    我们发现脚本需要传递两个参数,即url和选项
    然后我们在zabbix-server端进行键值测试

    [root@Zabbix_Server scripts]# zabbix_get -s 192.168.0.222 -p 10050 -k "zapache[127.0.0.1 TotalAccesses]"
    9
    [root@Zabbix_Server scripts]# zabbix_get -s 192.168.0.222 -p 10050 -k "zapache[www.yunjisuan.com version]"
    1.5
    [root@Zabbix_Server scripts]# zabbix_get -s 192.168.0.222 -p 10050 -k "zapache[www.yunjisuan.com ping]"
    1

    3.1.5 在zabbix-server的Web页面上监控apache

    (1)创建一个监控apache的主机

    QQ截图20180122233702.png-36.7kB

    QQ截图20180122233846.png-28.8kB

    (2)导入带有apache监控项的模版

    zabbix默认并没有监控apache的监控项模版。我们需要将它导入到apache中。在之前解压出来的目录中,有待导入的web模版

    [root@apache ~]# tree zapache-master/
    zapache-master/
    ├── httpd-server-status.conf.sample
    ├── README.md
    ├── zapache-template-active.xml #Web模版
    └── zapache-template.xml    #Web模版
    
    0 directories, 4 files
    

    我们将这两个.xml后缀的拷贝到windows上,然后从Web界面导入进去

    QQ截图20180122234457.png-17.2kB

    QQ截图20180122234649.png-32.8kB

    导入以后Web端就有监控apache的监控项模版了

    (3)将模版链接到apache主机

    QQ截图20180122234811.png-27.5kB

    QQ截图20180122234841.png-23.9kB

    QQ截图20180122235146.png-26.2kB

    3.2 实战监控nginx

    3.2.1 开启nginx状态页

    #在nginx的配置文件中,添加status配置
    location = /nginx-status {
        stub_status on;
        access_log  off;
        allow 127.0.0.1;
        allow 192.168.0.220;    #zabbix服务器地址一般是内网地址
        deny all;
    }

    3.2.2 访问设置好的nginx-status链接

    #在zabbix-server上通过如下方式获取nginx状态页面信息:
    root@Zabbix_Server ~]# curl 192.168.0.221/nginx-status
    Active connections: 1 
    server accepts handled requests
     634 634 618 
    Reading: 0 Writing: 1 Waiting: 0 
    
    nginx status详细说明如下:
    Active connections:对后端发起的活动连接数;
    accepts:nginx总共处理了多少个连接;
    handled:nginx成功创建了几次握手;
    requests:nginx总共处理了多少请求。
    Reading:nginx读取客户端的header数;
    Writing:nginx返回给客户端的header数;
    Waiting:nginx请求处理完成,正在等待下一请求指令的连接

    3.2.3 编写nginx状态监控脚本

    #下面是nginx状态监控抓取脚本,内容如下:
    [root@nginx scripts]# cat nginx_status.sh 
    #!/bin/bash
    # Set Variables
    
    HOST="127.0.0.1"
    PORT="80"
    
    #Functions to return nginx stats
    
    function active(){
        /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null | grep "Active" | awk '{print $NF}'
    }
    
    function reading(){
    
        /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null | grep "Reading" | awk '{print $2}'
    }
    
    function writing(){
    
        /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null | grep "Writing" | awk '{print $4}'
    }
    
    function accepts(){
    
        /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null | awk 'NR==3' | awk '{print $1}'
    
    }
    
    function handled(){
    
        /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null | awk 'NR==3' | awk '{print $2}'
    }
    
    function requests(){
    
        /usr/bin/curl "http://$HOST:$PORT/nginx-status" 2>/dev/null | awk 'NR==3' | awk '{print $3}'
    }
    
    function ping(){
    
        /sbin/pidof nginx | wc -l
    }
    
    # Run the requested function
    
    $1
    

    3.2.4 给脚本可执行权限并且授权

    [root@nginx scripts]# chmod +x nginx_status.sh 
    [root@nginx scripts]# chown zabbix.zabbix nginx_status.sh
    
    

    3.2.5 在zabbix-agent端配置nginx键值配置文件

    [root@nginx zabbix_agentd.d]# pwd
    /etc/zabbix/zabbix_agentd.d
    [root@nginx zabbix_agentd.d]# cat nginx.conf 
    UserParameter=nginx.active,/usr/bin/curl -s "http://127.0.0.1:80/nginx-status" | grep "Active" | awk '{print $NF}'
    UserParameter=nginx.status[*],/etc/zabbix/scripts/nginx_status.sh $1
    #重启agent客户端
    [root@nginx zabbix_agentd.d]# /etc/init.d/zabbix-agent restart
    Shutting down Zabbix agent:                                [  OK  ]
    Starting Zabbix agent:                                     [  OK  ]
    

    3.2.6 在zabbix-server端测试键值

    [root@Zabbix_Server ~]# zabbix_get -s 192.168.0.221 -k "nginx.status[reading]" -p 10050
    0
    [root@Zabbix_Server ~]# zabbix_get -s 192.168.0.221 -k "nginx.status[active]" -p 10050
    1
    [root@Zabbix_Server ~]# zabbix_get -s 192.168.0.221 -k "nginx.status[reading]" -p 10050
    0
    [root@Zabbix_Server ~]# zabbix_get -s 192.168.0.221 -k "nginx.status[writing]" -p 10050
    1
    [root@Zabbix_Server ~]# zabbix_get -s 192.168.0.221 -k "nginx.status[ping]" -p 10050
    1
    

    3.2.7 接下来我们需要在Web端导入nginx监控模版

    QQ截图20180126105544.png-29.5kB

    3.2.8 异常调试

    如果Zabbix图形界面一直没有获取到数据,可以通过在zabbix server上执行zabbix_get手动测试:
    /usr/local/zabbix/bin/zabbix_get -s 192.168.0.221 -p 10050 -k "nginx.status[active]"
    如果获取数据有问题,会给出相应提示,如果能够获取到数据,那就没问题了。

    四,Zabbix监控Tomcat操作实战

    zabbix监控tomcat,需要zabbix_server开启java poller,zabbix_java开启javaGateway,端口10052,Tomcat JMX开启12345端口,提供性能数据。

    数据获取流程为:java poller<-->javaGateway:10052<-->Tomcat:12345

    QQ截图20180126111607.png-76.3kB

    4.1 配置Tomcat JMX

    #配置jmx,在需要监控的tomcat服务器上,编辑catalina.sh,加入如下配置
    [root@Tomcat bin]# sed -n '249p' /usr/local/tomcat/bin/catalina.sh 
    CATALINA_OPTS="-server -Xms256m -Xmx512m -XX:PermSize=64M -XX:MaxPermSize=128m -Dcom.sun.management.jmxremote -Dcom.sun.management.jmxremote.authenticate=false -Dcom.sun.management.jmxremote.ssl=false -Djava.rmi.server.hostname=192.168.0.224 -Dcom.sun.management.jmxremote.port=12345"

    这里需要注意,必须增加-Djava.rmi.server.hostname选项,并且后面的IP就是tomcat服务器的IP

    4.2 重启Tomcat

    [root@Tomcat bin]# /usr/local/tomcat/bin/shutdown.sh 
    Using CATALINA_BASE:   /usr/local/tomcat
    Using CATALINA_HOME:   /usr/local/tomcat
    Using CATALINA_TMPDIR: /usr/local/tomcat/temp
    Using JRE_HOME:        /usr/local/jdk
    Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
    [root@Tomcat ~]# netstat -antup | grep java
    [root@Tomcat bin]# /usr/local/tomcat/bin/startup.sh 
    Using CATALINA_BASE:   /usr/local/tomcat
    Using CATALINA_HOME:   /usr/local/tomcat
    Using CATALINA_TMPDIR: /usr/local/tomcat/temp
    Using JRE_HOME:        /usr/local/jdk
    Using CLASSPATH:       /usr/local/tomcat/bin/bootstrap.jar:/usr/local/tomcat/bin/tomcat-juli.jar
    Tomcat started.
    [root@Tomcat zabbix]# netstat -antup | grep java
    tcp        0      0 :::54031                    :::*                        LISTEN      1521/java           
    tcp        0      0 :::8080                     :::*                        LISTEN      1521/java           
    tcp        0      0 :::53881                    :::*                        LISTEN      1521/java           
    tcp        0      0 :::12345                    :::*                      LISTEN      1521/java          #新增端口 
    tcp        0      0 ::ffff:127.0.0.1:8005       :::*                        LISTEN      1521/java           
    tcp        0      0 :::8009                     :::*                        LISTEN      1521/java       

    4.3 编译zabbix,加入java支持

    在zabbix server服务器上,编译安装zabbix-server,需要加上--enable-java,以支持jmx监控,如果之前的zabbix server没加此选项,那么需要重新编译安装,编译参数如下:

    ./configure --prefix=/usr/local/zabbix --with-mysql --with-net-snmp --with-libcurl --enable-server --enable-agent --enable-proxy --enable-java --with-libxml2

    特别提示:
    在启用--enable-java编译zabbix之前,zabbix server服务器上需要安装JDK,并需要设置JAVA_HOME,以让系统能够识别到jdk的路径

    4.3.1 在zabbix-server端安装JDK

    #解压jdk
    [root@Zabbix_Server ~]# tar xf jdk-8u60-linux-x64.tar.gz -C /usr/local/
    [root@Zabbix_Server ~]# ln -s /usr/local/jdk1.8.0_60/ /usr/local/jdk
    #配置java环境变量
    [root@Zabbix_Server ~]# sed -i.ori '$a export JAVA_HOME=/usr/local/jdk
    export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
    export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar' /etc/profile
    [root@Zabbix_Server ~]# tail -3 /etc/profile
    export JAVA_HOME=/usr/local/jdk
    export PATH=$JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATH
    export CLASSPATH=.$CLASSPATH:$JAVA_HOME/lib:$JAVA_HOME/lib/tools.jar
    #让环境变量立刻生效
    [root@Zabbix_Server ~]# source /etc/profile
    #检查java环境变量情况
    [root@Zabbix_Server ~]# which java
    /usr/local/jdk/bin/java
    [root@Zabbix_Server ~]# java -version
    java version "1.8.0_60"
    Java(TM) SE Runtime Environment (build 1.8.0_60-b27)
    Java HotSpot(TM) 64-Bit Server VM (build 25.60-b23, mixed mode)

    4.3.2 重新编译zabbix-server服务器端

    #重新编译zabbix-server服务器端之前
    [root@Zabbix_Server ~]# ll /usr/local/zabbix/sbin/
    total 8604
    -rwxr-xr-x 1 root root 1165774 Jan 20 15:16 zabbix_agentd

    -rwxr-xr-x 1 root root 3966037 Jan 20 15:16 zabbix_server
    
    #开始重新编译zabbix-server服务器端
    [root@Zabbix_Server ~]# 
    [root@Zabbix_Server ~]# /etc/init.d/zabbix_server stop
    Shutting down zabbix_server:                               [  OK  ]
    [root@Zabbix_Server ~]# cd /usr/src/zabbix-3.2.4/
    [root@Zabbix_Server zabbix-3.2.4]# ./configure --prefix=/usr/local/zabbix --with-mysql --with-net-snmp --with-libcurl --enable-server --enable-agent --enable-proxy --enable-java --with-libxml2
    [root@Zabbix_Server zabbix-3.2.4]# make && make install
    
    #重新编译zabbix-server服务器端之后
    [root@Zabbix_Server zabbix-3.2.4]# cd /usr/local/zabbix/sbin/
    [root@Zabbix_Server sbin]# ll
    total 8608
    -rwxr-xr-x 1 root root 1165774 Jan 25 22:22 zabbix_agentd

    -rwxr-xr-x 1 root root 2025 Jan 25 22:22 startup.sh     #启动java gateway服务

    提示:
    java gateway服务的配置脚本settings.sh不需要修改任何配置。

    4.3.3 启动java Gateway服务

    [root@Zabbix_Server zabbix_java]# /usr/local/zabbix/sbin/zabbix_java/startup.sh 
    [root@Zabbix_Server zabbix_java]# netstat -antup | grep 10052
    tcp        0      0 :::10052                    :::*                        LISTEN      13126/java 

    4.4 修改zabbix server 配置

    默认的情况下,zabbix server未启用javaPollers,需要修改zabbix_server.conf的如下配置

    [root@Zabbix_Server zabbix]# cd /usr/local/zabbix/etc/
    
    #修改以下配置文件的内容
    [root@Zabbix_Server etc]# cat -n zabbix_server.conf | sed -n '215p;223p;231p'
       215  # JavaGateway=
       223  # JavaGatewayPort=10052
       231  # StartJavaPollers=0
    
    #将上述配置文件内容修改成如下
    [root@Zabbix_Server etc]# cat -n zabbix_server.conf | sed -n '215p;223p;231p'
       215  JavaGateway=127.0.0.1   #JavaGateway的地址
       223  JavaGatewayPort=10052
       231  StartJavaPollers=5
    
    #查看已经打开的java poller进程
    [root@Zabbix_Server ~]# ps -ef | grep "java poller" | grep -v grep
    zabbix    13233  13172  0 Jan25 ?        00:00:00 /usr/local/sbin/zabbix_server: java poller #1 [got 0 values in 0.000001 sec, idle 5 sec]
    zabbix    13234  13172  0 Jan25 ?        00:00:00 /usr/local/sbin/zabbix_server: java poller #2 [got 0 values in 0.000015 sec, idle 5 sec]
    zabbix    13235  13172  0 Jan25 ?        00:00:00 /usr/local/sbin/zabbix_server: java poller #3 [got 0 values in 0.000001 sec, idle 5 sec]
    zabbix    13236  13172  0 Jan25 ?        00:00:00 /usr/local/sbin/zabbix_server: java poller #4 [got 0 values in 0.000001 sec, idle 5 sec]
    zabbix    13237  13172  0 Jan25 ?        00:00:00 /usr/local/sbin/zabbix_server: java poller #5 [got 0 values in 0.000001 sec, idle 5 sec]
    

    4.5 重启zabbix_server服务

    [root@Zabbix_Server ~]# /etc/init.d/zabbix_server start
    Starting zabbix_server:                                    [  OK  ]
    [root@Zabbix_Server ~]# netstat -antup | grep 10051
    tcp        0      0 0.0.0.0:10051               0.0.0.0:*                   LISTEN      13172/zabbix_server 
    tcp        0      0 192.168.0.220:10051         192.168.0.221:56752         TIME_WAIT   -                   
    tcp        0      0 192.168.0.220:10051         192.168.0.221:56754         TIME_WAIT   -                   
    tcp        0      0 192.168.0.220:10051         192.168.0.221:56751         TIME_WAIT   -                   
    tcp        0      0 192.168.0.220:10051         192.168.0.220:47162         TIME_WAIT   -           

    4.6 Zabbix图形界面配置

    4.6.1 创建一个主机利用JMX接口监控tomcat被监控端

    2.png-44.5kB

    4.6.2 导入zabbix监控tomcat的模版

    因为Zabbix自带的Tomcat模版有兼容性问题,并不好用,因此,我们导入自己制作的监控项模版

    1.png-28.6kB

    2.png-53.5kB

    3.png-29.9kB

    QQ截图20180128192111.png-42.8kB

    最后我们关联模版即可。

    五,Zabbix监控PHP-FPM操作实战

    php-fpm和nginx一样内建了一个状态页,对于想了解php-fpm的状态以及监控php-fpm非常有帮助

    5.1 启用php-fpm状态功能

    修改php-fpm配置文件,确保如下配置是打开状态:
    pm.status_path = /status,具体操作如下

    #在Zabbix-server端操作如下
    [root@Zabbix_Server etc]# pwd
    /usr/local/php/etc
    [root@Zabbix_Server etc]# ls
    pear.conf  php-fpm.conf  php-fpm.conf.default  php.ini
    [root@Zabbix_Server etc]# sed -n '360p' php-fpm.conf
    ;pm.status_path = /status
    [root@Zabbix_Server etc]# vim php-fpm.conf +360
    [root@Zabbix_Server etc]# sed -n '360p' php-fpm.conf
    pm.status_path = /status
    
    #重启php-fpm服务
    [root@Zabbix_Server ~]# netstat -antup | grep php-fpm
    tcp        0      0 127.0.0.1:9000              0.0.0.0:*                   LISTEN      1145/php-fpm
    [root@Zabbix_Server ~]# pkill php-fpm
    [root@Zabbix_Server ~]# netstat -antup | grep 9000
    [root@Zabbix_Server ~]# /usr/local/php/sbin/php-fpm 
    [root@Zabbix_Server ~]# netstat -antup | grep php-fpm
    tcp        0      0 127.0.0.1:9000              0.0.0.0:*                   LISTEN      18918/php-fpm

    5.2 nginx配置php-fpm状态页面

    在nginx配置文件nginx.conf里配置php状态页,操作如下

    [root@Zabbix_Server ~]# cd /usr/local/nginx/
    [root@Zabbix_Server nginx]# ls
    client_body_temp  conf  fastcgi_temp  html  logs  proxy_temp  sbin  scgi_temp  uwsgi_temp
    #配置php-fpm状态页面
    [root@Zabbix_Server nginx]# vim conf/nginx.conf
    [root@Zabbix_Server nginx]# cat conf/nginx.conf
    worker_processes  1;
    events {
        worker_connections  1024;
    }
    http {
        include       mime.types;
        default_type  application/octet-stream;
        sendfile        on;
        keepalive_timeout  65;
        server {
            listen       80;
            server_name  localhost;
            location / {
                root   html;
                index  index.php index.html index.htm;
            }
            location = /nginx-status {
                stub_status on;
                access_log off;
            }
            location = /status {         #添加此location
                include fastcgi_params;
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_param SCRIPT_FILENAME $fastcgi_script_name;
            }
            location ~ .php$ {
                fastcgi_pass 127.0.0.1:9000;
                fastcgi_index index.php;
                fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
                include fastcgi_params;
            }
        }
    }
    #重启动nginx服务
    [root@Zabbix_Server nginx]# nginx -t
    nginx: the configuration file /usr/local/nginx/conf/nginx.conf syntax is ok
    nginx: configuration file /usr/local/nginx/conf/nginx.conf test is successful
    [root@Zabbix_Server nginx]# /usr/local/nginx/sbin/nginx -s reload
    

    5.3 状态页浏览器访问测试

    php-fpm状态页比较个性化的一个地方是它可以带参数,可以带的参数有json、xml、html,使用zabbix或者nagios监控可以考虑使用xml或者默认方式。

    5.4 在Zabbix agent端修改配置

    在创建Zabbix的agent端键值配置文件的时候,我们可以考虑利用PHP-fpm状态页的不同输出格式来抓取数据。例如我们利用xml格式获取数据,操作如下:

    #查看xml格式PHP-fpm状态页数据
    root@Zabbix_Server nginx]# curl 127.0.0.1/status?xml
    <?xml version="1.0" ?>
    <status>
    <pool>www</pool>
    <process-manager>dynamic</process-manager>
    <start-time>1516953418</start-time>
    <start-since>3731</start-since>
    <accepted-conn>647</accepted-conn>
    <listen-queue>0</listen-queue>
    <max-listen-queue>4</max-listen-queue>
    <listen-queue-len>128</listen-queue-len>
    <idle-processes>2</idle-processes>
    <active-processes>1</active-processes>
    <total-processes>3</total-processes>
    <max-active-processes>3</max-active-processes>
    <max-children-reached>0</max-children-reached>
    <slow-requests>0</slow-requests>
    
    #创建zabbix监控的agent端键值配置文件
    [root@Zabbix_Server ~]# cd /etc/zabbix/zabbix_agentd.d/
    [root@Zabbix_Server zabbix_agentd.d]# cat userparameter_php-fpm.conf 
    UserParameter=php-fpm.status[*],/usr/bin/curl -s "http://127.0.0.1/status?xml" | grep "<$1>" | awk -F "[>|<]" '{print $$3}'    #这里需要注意在脚本里如果写成$3的话,脚本会认识是一个变量,因此我们需要用$$3
    
    #重启动agent客户端
    [root@Zabbix_Server ~]# /etc/init.d/zabbix-agent restart
    Shutting down Zabbix agent:                                [  OK  ]
    Starting Zabbix agent:                                     [  OK  ]

    5.5 进行键值配置文件测试

    [root@Zabbix_Server zabbix_agentd.d]# zabbix_get -s 192.168.0.220 -p 10050 -k "php-fpm.status[process-manager]"
    dynamic
    [root@Zabbix_Server zabbix_agentd.d]# zabbix_get -s 192.168.0.220 -p 10050 -k "php-fpm.status[start-since]"
    5634
    [root@Zabbix_Server zabbix_agentd.d]# zabbix_get -s 192.168.0.220 -p 10050 -k "php-fpm.status[active-processes]"

    六,Zabbix的Web监测功能

    Zabbix的Web监测功能,没有任何依赖,不需要agent端,全部依赖于Server的主动监测

    利用Web监测,监测Server端的nginx首页

    七,思考与作业

    请同学们在Zabbix监控MySQL的模版示例的基础上,自定义一个监控数据库主从复制的监控项

    IP地址主机名用途
    192.168.0.220 Zabbix_Server服务器 Zabbix监控端/主MySQL
    192.168.0.221 Nginx服务器 Nginx服务器/从MySQL
