[root@192 ~]# rpm -Uvh rpmforge-release-0.3.6-1.el5.rf.i386.rpm

安装后在/etc/yum.repos.d文件夹中生成mirrors-rpmforge rpmforge.repo 配置信息。
[root@192 ~]# cd /etc/yum.repos.d/
[root@192 yum.repos.d]# ls
CentOS-Base.repo CentOS-Base.repo.bak mirrors-rpmforge
CentOS-Base.repo.5 CentOS-Media.repo rpmforge.repo
有了这个RPMforge Repository的源就可以轻松的开始munin

[root@192 munin]# pwd
/etc/munin
[root@192 munin]# ls

munin-node.confdafault plugins.conf
plugin-conf.d templates

# mkdir /var/www/html/munin

这个很重要否则日志会报错
chown -R munin:munin /etc/munin/templates
chown -R munin:munin /var/www/html/munin
简单设置 munin的配置文件/etc/munin/munin.conf
vi /etc/munin/munin.conf
内容如下：
dbdir /var/lib/munin
htmldir /var/www/html/munin
logdir /var/log/munin
rundir /var/run/munin
tmpldir /etc/munin/templates
[localhost]
address 127.0.0.1
use_node_name yes
＃添加一个客户端
[lxu]

use_node_name yes

设置 munin启动脚步并启动 munin
chkconfig --levels 235 munin-node on
/etc/init.d/munin-node start

启动munin

在运行前我们还有一步工作要做，那就是更改/var/www/munin目录的权限

chown munin.munin -R /var/www/munin
sudo /etc/init.d/munin-node start

chown munin.munin -R /var/www/munin
sudo /etc/init.d/munin-node start

chown munin.munin -R /var/www/munin
sudo /etc/init.d/munin-node start

现在munin就已经在工作了，你可以在 /var/www/munin下边看到它生成html内容，当然这样看很不方便，我们可以利用nginx来看这些内容，现在我们配置一下nginx。

指向Tomcat ，Tomcat 中的server.xml配置

<Context path="/" docBase="/var/www/html/munin" debug="0" reloadable="false" crossContext="true" allowLinking="true"/>
