CentOS 7.8 x64 安装zabbix 5.0 LTS

CentOS 7.8 x64 安装zabbix 5.0 LTS

官网教程

• https://www.zabbix.com/download?zabbix=5.0&os_distribution=centos&os_version=7&db=mysql&ws=nginx
  

手把手安装

1. 安装zabbix库

   • $ rpm -Uvh https://repo.zabbix.com/zabbix/5.0/rhel/7/x86_64/zabbix-release-5.0-1.el7.noarch.rpm	
     $ yum clean all	【清除yum缓存】
     

2. 安装zabbix server 和 agent

   • $ yum install zabbix-server-mysql zabbix-agent
     【后面出现的交互确认 全部选择Y】
     

3. 安装zabbix前端

   • $ yum install centos-release-scl	【安装前端release】
     

   • $ vi /etc/yum.repos.d/zabbix.repo
     【修改配置】
     	...
     	enabled=1
     	...
     

4. 安装mysql数据库

   • 本次mysql安装我们选择rpm安装方式，安装的mysql版本为5.7.30

   1. 下载mysql 5.7.30 rpm包

      • wget -i -c http://dev.mysql.com/get/mysql-5.7.30-1.el7.x86_64.rpm-bundle.tar

   2. 解压

      • tar -xvf mysql-5.7.30-1.el7.x86_64.rpm-bundle.tar

   3. 查看系统里是否已经有安装过mysql，有则卸载

      • rpm -qa|grep mariadb 【查看】
      • rpm -e --nodeps mariadb-libs-5.5.65-1.el7.x86_64【卸载】

   4. 安装mysql5.7所需要的依赖

      • yum install libaio
      • yum install perl
      • yum install net-tools

   5. 安装mysql

      • rpm -ivh mysql-community-common-5.7.30-1.el7.x86_64.rpm
      • rpm -ivh mysql-community-libs-5.7.30-1.el7.x86_64.rpm
      • rpm -ivh mysql-community-libs-compat-5.7.30-1.el7.x86_64.rpm
      • rpm -ivh mysql-community-client-5.7.30-1.el7.x86_64.rpm
      • rpm -ivh mysql-community-server-5.7.30-1.el7.x86_64.rpm

   6. 配置mysql数据库

      • 启动mysql

        • systemctl start mysqld.service

      • 查看mysql运行状态

        • systemctl status mysqld.service

      • 找到root初始密码

        • grep "password" /var/log/mysqld.log

      • 修改root密码

        • ALTER USER 'root'@'localhost' IDENTIFIED BY 'new password';

      • 开启mysql的远程访问【下面命令开启的IP是 192.168.0.1，如要开启所有的，用%代替IP】

        • grant all privileges on . to 'root'@'192.168.0.1' identified by 'password' with grant option;
        • flush privileges;
        • exit

      • 为firewalld添加开放端口【添加mysql端口3306和Tomcat端口8080】

        • firewall-cmd --zone=public --add-port=3306/tcp --permanent
        • firewall-cmd --zone=public --add-port=8080/tcp --permanent
        • 或者选择吧firewalld服务临时关闭【service firewalld stop】

      • 修改字符集

        • 描述【重新登录mysql，然后输入status，经过观察，不难发现里面有两个不是utf-8】

        • 改为utf-8方法：

          • vi /etc/my.cnf

          • 新增下列四行
            [client]
            default-character-set=utf8
            
            character-set-server=utf8
            collation-server=utf8_general_ci
            

          • 实现的效果如下所示：
            ​```
            [client]
            default-character-set=utf8
            # For advice on how to change settings please see
            # http://dev.mysql.com/doc/refman/5.7/en/server-configuration-defaults.html
             
            [mysqld]
            #
            # Remove leading # and set to the amount of RAM for the most important data
            # cache in MySQL. Start at 70% of total RAM for dedicated server, else 10%.
            # innodb_buffer_pool_size = 128M
            #
            # Remove leading # to turn on a very important data integrity option: logging
            # changes to the binary log between backups.
            # log_bin
            #
            # Remove leading # to set options mainly useful for reporting servers.
            # The server defaults are faster for transactions and fast SELECTs.
            # Adjust sizes as needed, experiment to find the optimal values.
            # join_buffer_size = 128M
            # sort_buffer_size = 2M
            # read_rnd_buffer_size = 2M
            datadir=/var/lib/mysql
            socket=/var/lib/mysql/mysql.sock
            character-set-server=utf8
            collation-server=utf8_general_ci
            # Disabling symbolic-links is recommended to prevent assorted security risks
            symbolic-links=0
             
            log-error=/var/log/mysqld.log
            pid-file=/var/run/mysqld/mysqld.pid
            ​```
            

          • 重启mysqld 服务

5. 初始化zabbix的数据库

   • note：

     • mysql口令：root abcD_123
       zabbix口令：zabbix abcD_123
       

   • mysql> create database zabbix character set utf8 collate utf8_bin; 【修改字符集】

   • mysql> create user zabbix@localhost identified by 'password';【创建用户zabbix和密码】

   • mysql> grant all privileges on zabbix.* to zabbix@localhost;【授权登录】

   • mysql> quit;

   • $ zcat /usr/share/doc/zabbix-server-mysql*/create.sql.gz | mysql -uzabbix -p zabbix 【导入初始化的schema和数据】
     

6. zabbix server配置

   • $ vi /etc/zabbix/zabbix_server.conf
     DBPassword=password【将数据库password填入】
     

7. zabbx前端php配置

   • $ vi /etc/opt/rh/rh-nginx116/nginx/conf.d/zabbix.conf
     【解开注释】
     # listen 80;
     # server_name example.com;
     

   • $ vi /etc/opt/rh/rh-php72/php-fpm.d/zabbix.conf
     【修改为】
     listen.acl_users = apache,nginx
     
     【解开注释】
     php_value[date.timezone] = Asia/Shanghai
     
     

8. 启动zabbix server and agent 进程

   • $ systemctl restart zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm
     $ systemctl enable zabbix-server zabbix-agent rh-nginx116-nginx rh-php72-php-fpm
     

9. 登录zabbix

   • 官方quick start：https://www.zabbix.com/documentation/5.0/manual/quickstart/login
   • 默认密码是Admin/zabbix

10. 安装完成后遇到的问题

    • 问题描述：登录zabbix前端，发现界面下方一直有报错，报错释义”zabbix server启动失败“

    • 查看日志：/var/log/zabbix/zabbix_server.log , 发现无法绑定socket到zabbix_server_alerter.sock，访问被拒绝

    • 原因：selinux问题

    • 解决方法：关闭selunx

      • $ sestatus【查看selinux状态】
        $ vi /etc/selinux/config
        【配置修改如下】
        ...
        SELINUX=disabled
        ...
        SELINUXTYPE=targeted 
        
        $ reboot 【修改配置文件，重启永久关闭】
        或者 $ setenforce 0【临时关闭】
