在CENTOS上安装APACHE,MUNIN（对MONGODB的PLUGIN未成功）

最近公司忙死，

为了配合大家公司，在ESX上的CENTOS里，再上一个作网站资源监控的MUNIN。

（NTOP，在考虑当中，测试已通过）

由于对APACHE执行CGI不甚清楚，搞了很久的这些权限问题。

最后，在一篇最简单的参考文档里搞定。

看来，PYTHON和APACHE的CGI,FASTCGI也要去了解一下了。。

Installing Munin in RHEL, CentOS & Fedora

Installing Munin is very simple, just follow my below step-by-step commands to install it on your server.

Step 1: Installing EPEL Repository for RHEL & CentOS

Munin can be installed by using Fedora‘s EPEL repository under RHEL 6.3/6.2/6.1/6/5.8 and CentOS 6.3/6.2/6.1/6/5.8. Just, run the following commands as root user to install it using wget.

RHEL/CentOS 6

# wget http://download.fedoraproject.org/pub/epel/6/i386/epel-release-6-5.noarch.rpm
# rpm -ivh epel-release-6-5.noarch.rpm

RHEL/CentOS 5

# wget http://download.fedoraproject.org/pub/epel/5/i386/epel-release-5-4.noarch.rpm
# rpm -ivh epel-release-5-4.noarch.rpm

Note : Fedora users don’t need to install EPEL repository, because munin is included in Fedora and can be installed using yum.

Step 2: Installing Munin

Just run the following command as root user.

# yum --enablerepo=epel -y install munin munin-node

By default the above installation creates following directories.

1. /etc/munin/munin.conf : Munin master configuration file.
2. /etc/cron.d/munin : Munin cron file.
3. /etc/httpd/conf.d/munin.conf : Munin Apache configuration file.
4. /var/log/munin : Munin log directory.
5. /var/www/munin : Munin web directory.
6. /etc/munin/munin-node.conf : Munin Node master configuration file.
7. /etc/munin/plugins.conf : Munin plugins configuration file.
8. /etc/rc.d/init.d/munin-node : Munin start-up service daemon.

Step 3: Configuring Munin

Open file /etc/httpd/conf/httpd.conf file and add the following lines of code at the bottom.

Alias /munin /var/www/munin
<Directory /var/www/munin>
    Options FollowSymLinks
    AllowOverride None
    Order allow,deny
    Allow from all
</Directory>

Restart Apache and then create system start-up links for Munin and start it.

# /etc/init.d/httpd restart
# chkconfig --levels 235 munin-node on
# /etc/init.d/munin-node start

Step 4: Accessing Munin Web Interface

Wait for 30 minutes so that Munin can generate graphs and displayed it. To see first output of graphs, open your browser and navigate tohttp://www.example.com/munin.
