# 前言 #

最近在研究云监控的相关工具,感觉ganglia颇有亮点,能从一个集群整体的角度来展现数据. 但是安装过程稍过复杂,相关依赖稍多,故写此文章与大家分享下.

本文不讲解相关原理,若想了解请参考其他资料.

本文目的: 即使之前未触过ganglia,也能按照文中步骤搭建自己的ganglia监控集群.

# 5.编译安装 #

## 5.1 安装ganglia (全部节点都要安装) ##

# tar -zxf ganglia-3.6.0.tar.gz
    # cd ganglia-3.6.0
    # ./configure --prefix=/usr/local/ganglia --with-gmetad --enable-gexec --with-python=/usr/local

    Type "make" to compile.
    # make && make install

## 5.2 安装ganglia-web (主节点安装) ##

# tar -zxf ganglia-web-3.5.10.tar.gz -C /export/home/ganglia/
    # cd /export/home/ganglia/ganglia-web-3.5.10
    # cp conf_default.php conf.php

vi conf.php    调整为如下内容

$conf['gweb_confdir'] = "/export/home/ganglia/ganglia-web-3.5.10"; $conf['gmetad_root'] = "/export/home/ganglia";

vi header.php

<?php session_start(); ini_set('date.timezone','PRC');      --修改时区为本地时区 if (isset($_GET['date_only'])) {   $d = date("r");   echo $d;   exit(0); }

配置临时目录

cd /export/home/ganglia/ganglia-web-3.5.10/dwoo
    mkdir cache
    chmod 777 cache
    mkdir compiled
    chmod 777 compiled

## 5.3 安装apache (主节点安装) ##

tar -zxf httpd-2.2.23.tar.gz
     cd httpd-2.2.23
     ./configure --prefix=/usr/local/apache2
     make && make install

## 5.4 安装php (主节点安装) ##

tar -zxf php-5.4.10.tar.gz
    cd php-5.4.10
    ./configure --prefix=/usr/local/php  --with-apxs2=/usr/local/apache2/bin/apxs  --with-mysql=/usr
    make  && make install

## 5.5 使用apache发布ganglia-web (主节点安装) ##

vi /usr/local/apache2/conf/httpd.conf

....
    Listen 80
    ....
    
    <IfModule dir_module>
        DirectoryIndex index.html index.php
        AddType application/x-httpd-php .php
    </IfModule>
    ....
    
    # 在文件最后增加如下内容
    # ganglia
    Alias /ganglia "/export/home/ganglia/ganglia-web-3.5.10"
    <Directory "/export/home/ganglia/ganglia-web-3.5.10">
         AuthType Basic
         Options None
         AllowOverride None
         Order allow,deny
         Allow from all
    </Directory>

启动httpd服务

/usr/local/apache2/bin/apachectl restart

# 6.配置Ganglia #

## 6.1 配置gmetad (主节点配置) ##

cd ganglia-3.6.0
    cp ./gmetad/gmetad.init /etc/init.d/gmetad
    cp ./gmetad/gmetad.conf /usr/local/ganglia/etc/

vi /etc/init.d/gmetad  --修改如下内容

GMETAD=/usr/local/ganglia/sbin/gmetad

vi /usr/local/ganglia/etc/gmetad.conf     -- 修改如下内容

data_source "duangr-cluster" 10 duangr-1  duangr-2  duangr-3
    xml_port 8651
    interactive_port 8652
    rrd_rootdir "/export/home/ganglia/rrds"
    case_sensitive_hostnames 0

修改rrds数据目录所有者

chown -R nobody:nobody /export/home/ganglia/rrds

启动gmetad服务,并设为开机自动运行

service gmetad restart
    chkconfig --add gmetad

## 6.2 配置gmond (全部节点配置) ##

cd ganglia-3.6.0
    cp ./gmond/gmond.init /etc/init.d/gmond 
    ./gmond/gmond -t > /usr/local/ganglia/etc/gmond.conf

vi /etc/init.d/gmond  --修改如下内容

GMOND=/usr/local/ganglia/sbin/gmond

vi /usr/local/ganglia/etc/gmond.conf      -- 修改如下内容

cluster {
      name = "duangr-cluster"
      owner = "nobody"
      latlong = "unspecified"
      url = "unspecified"
    }

复制python module到ganglia部署目录

mkdir /usr/local/ganglia/lib64/ganglia/python_modules
    cp ./gmond/python_modules/*/*.py  /usr/local/ganglia/lib64/ganglia/python_modules

安装程序ganglia-3.6.0默认提供了一些python module的配置文件,只需要部署到 /usr/local/ganglia/etc/conf.d 目录下面即可生效

若对默认提供的这些监控脚本不太关心,可以跳过下面这步:

cp ./gmond/python_modules/conf.d/*.pyconf  /usr/local/ganglia/etc/conf.d

启动gmond服务,并设为开机自动运行

service gmond  restart
    chkconfig --add  gmond
