    Ganglia是监控集群机器运行状态的软件

    1、环境准备

    1.1 expat安装
    软件名称:expat-2.1.0.tar.gz
    软件地址:http://sourceforge.net/projects/expat/files/expat/
    安装步骤:tar -zxvf expat-2.1.0.tar.gz
    cd expat-2.1.0
    ./configure --prefix=/opt/local/expat-2.1.0
    make
    make install
    cd /opt/local/expat-2.1.0
    mkdir lib64

    ./configure --prefix=/opt/local/apr-1.5.2
    make
    make install
    说明:ganglia编译时默认寻找/opt/local/apr-1.5.2/include下的文件,即需做
    cd /opt/local/apr-1.5.2/include/apr-1
    cp -R * /opt/local/apr-1.5.2/include
    如果64位机器需要拷贝动态链接库
    cd /opt/local/apr-1.5.2
    mkdir lib64
    cd lib
    cp -R * /opt/local/apr-1.5.2/lib64

    软件地址:http://httpd.apache.org/download.cgi 
    安装步骤:tar -zxvf httpd-2.2.32.tar.gz
    mkdir /opt/local/apache2
    cd httpd-2.2.32
    ./configure --prefix=/opt/local/apache2 --enable-module=shared
    make
    make install
    
     
    
    编辑 /usr/local/apache2/conf/httpd.conf 文件 
      vi conf/httpd.conf 
    找到:
    AddType application/x-compress .Z
    AddType application/x-gzip .gz .tgz
    在后面添加:
    AddType application/x-httpd-php .php(使Apcche支持PHP)
    AddType application/x-httpd-php-source .php5 
    找到:
    <IfModule dir_module>
    DirectoryIndex index.html
    </IfModule>
    添加:
    <IfModule dir_module>
    DirectoryIndex index.html index.php
    </IfModule> 
    找到:
    #ServerName www.example.com:80
    修改为 ServerName 192.168.46.163:80
    
    更改httpd的访问配置路径Document Root
    mkdir -p /var/www/html/ 
    找到Document Root修改为
    DocumentRoot "/var/www/html"
    
    找到Directory 修改
    <Directory "/var/www/html">
    
    打开apache配置文件httpd.conf,找到这么一段:
    <Directory />
    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    deny from all
    Satisfy all
    </Directory>
    
    问题:
    httpd: unrecognized service”
    
    解决方法:
    将httpd注册为系统服务即可,可使用如下代码:
    #cd /opt/local/apache2/bin/ ##进入你的Apache安装目录下的bin文件夹下 #cp apachectl /etc/rc.d/init.d/httpd
    #vi /etc/rc.d/init.d/httpd
    在#!/bin/sh这行下增加
    # chkconfig: 2345 50 90 # description:Activates/Deactivates Apache Web Server)

    1.8 安装PHP

    软件名称:php-5.6.30.tar.gz
    软件地址:http://www.php.net/downloads.php
    安装步骤:tar -zxvf php-5.6.30.tar.gz
    cd php-5.6.30
    ./configure --prefix=/opt/local/php --with-apxs2=/opt/local/apache2/bin/apxs
    make
    make install

    cp /opt/php-5.6.30/php.ini-development /opt/local/php/lib/php.ini

    2、ganglia的安装

    软件下载:https://sourceforge.net/projects/ganglia/files/
    安装步骤:tar -zxvf ganglia-3.7.2.tar.gz
    cd ganglia-3.7.2
    ./configure --prefix=/opt/local/ganglia-3.7.2 --with-librrd=/opt/local/rrdtool-1.4.8 --with-libapr=/opt/local/apr-1.5.2 --with-libexpat=/opt/local/expat-2.1.0 --with-libconfuse=/opt/local/confuse-2.7 --enable-gexec --enable-status --with-gmetad --with-libpcre=/opt/local/pcre-8.36 --with-static-modules --sysconfdir=/etc/ganglia
    make
    make install

    3、服务段配置

    cd /opt/ganglia-3.7.2/gmetad --软件包解压位置
    cp gmetad.init /etc/init.d/gmetad
    修改 vi /etc/init.d/gmetad
    将GMETAD=/usr/sbin/gmetad修改为GMETAD=/opt/local/ganglia-3.7.2/sbin/gmetad
    将daemon $GMETAD 修改为daemon $GMETAD -c /etc/ganglia/gmetad.conf
    说明:1、/opt/local/ganglia-3.7.2为ganglia安装位置
    2、如果不修改GMETAD值,可执行“cp /opt/local/ganglia-3.7.2/sbin/gmetad /usr/sbin/”代替

    修改 vi /etc/ganglia/gmetad.conf
    data_source "hadoop cluster" hadoop-namenode-01
    gridname "hadoop cluster"
    setuid_username "nobody"
    rrd_rootdir "/var/lib/ganglia/rrds"

    (“Hadoop Cluster”为整个监控架构的名字,可自定义
    hadoop-namenode-01 表示节点域名和IP)
    说明:如果安装ganglia的./configure 没有参数 --sysconfdir=/etc/ganglia
    则 mkdir /etc/ganglia
    切换至ganglia-3.7.2.tar.gz解压目录ganglia-3.7.2/gmetad
    执行“cp gmetad/gmetad.conf /etc/ganglia/”
    查看gmetad运行是否正常 ps -ef|grep gmetad
    查看日志 tail /var/log/messages

    mkdir -p /var/lib/ganglia/rrds
    mkdir -p /var/lib/ganglia/dwoo
    chown -R nobody:nobody /var/lib/ganglia

    ##因ods1主机(192.168.10.3)既是ganglia服务端又是客户端,所以可以直接之配置客户端服务 具体参照4.3,不需要重新安装,

    4、客户端配置

    4.1.软件准备
    需安装:expat、apr、apr-util、confuse、pcre
    具体安装方法见:4.2、4.3、4.4、4.5、4.7

    4.2.ganglia安装
    具体见5.1安装方法。
    在“./configure”参数时稍作修改:
    ./configure --prefix=/opt/local/ganglia-3.7.2 --enable-gexec --enable-status --with-libapr=/opt/local/apr-1.5.2 --with-libexpat=/opt/local/expat-2.1.0 --with-libconfuse=/opt/local/confuse-2.7 --with-libpcre=/opt/local/pcre-8.36 --sysconfdir=/etc/ganglia
    make
    make install

    4.3.客户端配置
    cd /opt/ganglia-3.7.2/gmond ----软件包解压位置
    cp gmond.init /etc/init.d/gmond
    ./gmond -t > /etc/ganglia/gmond.conf
    说明:如果安装ganglia的./configure 没有参数 --sysconfdir=/etc/ganglia
    则 mkdir /etc/ganglia

    修改 vi /etc/init.d/gmond
    将GMOND=/usr/sbin/gmond修改为GMOND=/opt/local/ganglia-3.7.2/sbin/gmond
    将daemon $GMOND 修改为daemon $GMOND -c /etc/ganglia/gmond.conf

    说明:1、/opt/local/ganglia-3.7.2为ganglia安装位置
    2、如果不修改GMOND值,可执行“cp /opt/local/ganglia-3.7.2/sbin/gmond /usr/sbin/”代替

    修改 vi /etc/ganglia/gmond.conf

    globals {
      daemonize = yes
      setuid = yes
      user = nobody --若要修改

    /*
    * The cluster attributes specified will be used as part of the <CLUSTER>
    * tag that will wrap all hosts collected by this instance.
    */
    cluster {
      name = "hadoop cluster"
      owner = "nobody"
      latlong = "unspecified"
      url = "unspecified"
    }

    /* Feel free to specify as many udp_send_channels as you like. Gmond
    used to only support having a single channel */
    udp_send_channel {
      #bind_hostname = yes # Highly recommended, soon to be default.
      # This option tells gmond to use a source address
      # that resolves to the machine's hostname. Without
      # this, the metrics may appear to come from any
      # interface and the DNS names associated with
      # those IPs will be used to create the RRDs.
      # mcast_join = 239.2.11.71
      host = 192.168.46.163
      port = 8649
      ttl = 1
    }

    /* You can specify as many udp_recv_channels as you like as well. */
    udp_recv_channel {
      # mcast_join = 239.2.11.71
      port = 8649
      #bind = 192.168.46.163
      retry_bind = true
      # Size of the UDP buffer. If you are handling lots of metrics you really
      # should bump it up to e.g. 10MB or even higher.
      # buffer = 10485760

    }

    5、WEB端配置

    5.1.软件安装
      软件名称:ganglia-web-3.7.2
      软件地址:http://sourceforge.net/projects/ganglia/files/
      安装步骤:tar -zxvf ganglia-web-3.7.2.tar.gz -C /var/www/html/
           cd /var/www/html/ganglia-web-3.7.2
             vi Makefile

      GDESTDIR = /var/www/html/ganglia
      APACHE_USER = nobody

      make install --yum -y install rsync
    5.2.软件配置
      cd /var/www/html/ganglia
      cp conf_default.php conf.php
    修改 vi conf.php
    将$conf['external_location'] = "http://localhost/ganglia-2";
    修改为 $conf['external_location'] = "http://192.168.46.163/ganglia";

    将相应目录修改为777权限
    chmod 777 -R /var/lib/ganglia-web/dwoo

    6、启动服务

    service gmetad start
    service gmond start
    service httpd start

    7、问题解决

    问题1、gmetad进程没有起来
    步骤:
    先修改将datasource减少

    若还不行自行创建/var/lib/ganglia的目录
    mkdir -p /var/lib/ganglia/rrds
    mkdir -p /var/lib/ganglia/dwoo

    启动httpd报错查看日志/opt/local/apache2/logs

    问题2、/opt/pcre-8.36/missing: line 81: automake-1.14: command not found
    解决方式:autoreconf -v --install --force



    问题3、/usr/local/lib/libpython2.7.a: could not read symbols: Bad value
    解决方式:
    重新编译Python
    ./configure --prefix=/usr/local/ CFLAGS=-fPIC
    make
    make install


    问题4、Can't locate ExtUtils/MakeMaker.pm
    解决方式:
    yum install -y perl-ExtUtils-CBuilder perl-ExtUtils-MakeMaker

    问题5、ganglia图片显示不了
    cd /var/www/html/ganglia/
    vi conf.php
    $conf['rrdtool'] = "/opt/local/rrdtool-1.4.8/bin/rrdtool";

    问题6、 please set date.timezone to select your timezone. in /var/www/html/ganglia/header.php on line 5
    问题解决:
    date_default_timezone_set('Asia/Shanghai'); //设置时间区域为“亚洲/上海”,也就是中国。

    问题7、Ganglia访问失败 There was an error collecting ganglia data (127.0.0.1:8652): fsockopen error: Permission denied

    解决:需要关闭selinux:vi /etc/selinux/config,把SELINUX=enforcing改成SELINUX=disabled;需要重启机器。

    问题8、 please set date.timezone to select your timezone. in /var/www/html/ganglia/header.php on line 5
    问题解决:
    date_default_timezone_set('Asia/Shanghai'); //设置时间区域为“亚洲/上海”,也就是中国。

     

    8、配置Hadoop

    vi hadoop-metrics2.properties
    
    hadoop集群配置ganglia
    
    修改namenode节点
    
    namenode.sink.ganglia.servers=hadoop-namenode-01:8649
    
    #datanode.sink.ganglia.servers=yourgangliahost_1:8649,yourgangliahost_2:8649
    
    resourcemanager.sink.ganglia.servers=hadoop-namenode-01:8649
    
    #nodemanager.sink.ganglia.servers=yourgangliahost_1:8649,yourgangliahost_2:8649
    
    mrappmaster.sink.ganglia.servers=hadoop-namenode-01:8649
    
    jobhistoryserver.sink.ganglia.servers=hadoop-namenode-01:8649
    
    
    修改datanode节点
    
    #namenode.sink.ganglia.servers=nna:8649
    
    datanode.sink.ganglia.servers=zk-datanode-01:8649
    
    #resourcemanager.sink.ganglia.servers=nna:8649
    
    nodemanager.sink.ganglia.servers=zk-datanode-01:8649
    
    #mrappmaster.sink.ganglia.servers=nna:8649
    
    #jobhistoryserver.sink.ganglia.servers=nna:8649

    其他的类推配置。
