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

中国网络水泥

　　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.

• /etc/munin/munin.conf : Munin master configuration file.
  
• /etc/cron.d/munin : Munin cron file.
  
• /etc/httpd/conf.d/munin.conf : Munin Apache configuration file.
  
• /var/log/munin : Munin log directory.
  
• /var/www/munin : Munin web directory.
  
• /etc/munin/munin-node.conf : Munin Node master configuration file.
  
• /etc/munin/plugins.conf : Munin plugins configuration file.
  
• /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

Options FollowSymLinks
AllowOverride None
Order allow,deny
Allow from all

　　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 to http://www.example.com/munin.
