提醒：内存1G  硬盘15G(硬盘最好不要低于15G，不然安装期间会出问题)

        Selinux和防火墙先关闭，安装成功后再配置

        1.关闭selinux  vim/etc/sysconfig/selinu更改：SELINUX=enforcing 为 SELINUX=disabled

              




           2.关闭iptables  service iptables stop

监控主机ip：192.168.0.90

              Mask：255.255.255.0

              Gateway：192.168.0.1

              DNS：192.168.0.52

被监控主机：apps01.semi.htche.com (192.168.0.56)

    web01.semi.htche.com (192.168.0.58)

    res01.semi.htche.com (192.168.0.57)

db01.semi.htche.com(192.168.0.55)

准备：# yum update

# yum install vim-y

         # Yum install wget -y

一．   前提依赖

1.     主机环境检查(全部主机节点)

# yum install  gcc glibc glibc-common rrdtool rrdtool-devel apr  apr-devel expat expat-devel  pcre pcre-devel dejavu-lgc-sans-mono-fonts dejavu-sans-mono-fonts-y

2.     dejavu

# yum install dejavu* -y

3.      rrdtool

# yum install rrdtool* -y

4.     apr

# yum install apr* -y

5.     libexpat

# yum install expat* -y

6.      libpcre

# yum install pcre* -y

7.     Confuse

# cd /usr/src

# wget   http://ftp.yzu.edu.tw/nongnu//confuse/confuse-2.7.tar.gz

# tar -zxf confuse-2.7.tar.gz

# cd confuse-2.7

# ./configure CFLAGS=-fPIC --disable-nls

# make && make install

8.     Python

# cd /usr/src

# wget  https://www.python.org/ftp/python/2.7.3/Python-2.7.3.tgz

#tar -jxf Python-2.7.3.tgz

# cd Python-2.7.3

# ./configure  --prefix=/usr/local  --enable-shared

# make && make install

配置共享库

# vim /etc/ld.so.conf

-- 增加如下内容

/usr/local/lib

启用配置

# ldconfig

检查是否生效

# ldconfig -v |grep"libpython2.7.so"

二．   编译安装

要yum安装zlib*   yum install zlib* -y

A.   安装ganglia (全部节点都要安装)# cd/usr/src

#wget http://jaist.dl.sourceforge.net/ ... anglia-3.6.0.tar.gz

# 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

Copyright (c) 2005 University of California, Berkeley

Version: 3.6.0

Library: Release 3.6.0 0:0:0

Type "make" to compile.

# make && make install

B.   安装ganglia-web (主节点安装)

#mkdir -p /export/home/ganglia/

# cd /usr/src

#wgethttp://iweb.dl.sourceforge.net/p ... a-web-3.5.10.tar.gz

# tar -zxvf 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

# vim 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";

# vim 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

注意：以下apache和php已在nagios环境下配置，由于ganglia和nagios在同一台机子上，所以安装ganglia时不要再重复安装apache和php

C.   安装apache (主节点安装)

# cd /usr/src

# wget http://archive.apache.org/dist/httpd/httpd-2.2.23.tar.gz

# tar -zxvf httpd-2.2.23.tar.gz

# cd httpd-2.2.23

#./configure --prefix=/usr/local/apache2

# make && make install

D.   安装php (主节点安装)

要提前yum安装libxml2*

# yum install mysql-devel -y

# yum install libxml2* -y

# exportLDFLAGS=-L/usr/lib64/mysql

# mkdir /usr/lib/mysql

# cp /usr/lib64/mysql/*/usr/lib/mysql/

# cd /usr/src

# wget http://museum.php.net/php5/php-5.4.10.tar.gz

# 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

E.    使用apache发布ganglia-web (主节点安装)

# vim/usr/local/apache2/conf/httpd.conf

ServerName localhost[url=]:80[/url]

....

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

三．   配置ganglia

A.   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/

# vim /etc/init.d/gmetad --修改如下内容

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

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

data_source "htchecluster" 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

# mkdir/export/home/ganglia/rrds

# 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

B.   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

# vim /etc/init.d/gmond --修改如下内容

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

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

cluster {

  name = "htchecluster"

  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

四．   安装完成
