Munin 安装配置

# uname -r
2.6.18-53.el5


用第三方的RPMforge Repository yum源来快速安装munin

wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm
[root@192 ~]# rpm -Uvh rpmforge-release-0.3.6-1.el5.rf.i386.rpm
warning: rpmforge-release-0.3.6-1.el5.rf.i386.rpm: Header V3 DSA signature: NOKEY, key ID 6b8d79e6

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

安装和配置 munin
执行yum 完成安装

简单设置 munin的配置文件/etc/munin/munin.conf
vi /etc/munin/munin.conf
内容如下：

＃添加一个客户端

设置 munin启动脚步并启动 munin
chkconfig --levels 235 munin-node on

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

Java代码  

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

chown munin.munin -R /var/www/muninsudo /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"/>
