Munin是一个强大的服务器性能状态监控软件

1. Debian或者Ubuntu系统：

   apt-get install munin munin-node

2. 编辑/etc/munin/munin.conf 取消下面几行注释

   dbdir /var/lib/munin
   htmldir /var/cache/munin/www
   logdir /var/log/munin
   rundir  /var/run/munin
   tmpldir /etc/munin/templates
   

3. 加入检测节点(用小写以免出现各种奇葩错误)

   [monitor]
   address 127.0.0.1
   use_node_name yes
   

4. 配置Nginx

   server {
       root /var/cache/munin/www;   
       listen 80;
       server_name munin.yourdomain.com;
       location / {
           auth_basic "Monitor Require Auth";
           auth_basic_user_file /etc/nginx/htpassword.pass;
       }
   }
   

5. 安装端口流量检测插件(按如下代码配置iptables)

   iptables -I INPUT -p udp -d 12.34.56.78 --dport 8767 -m comment --comment "ACC-teamspeak"
   iptables -I OUTPUT -p udp -s 12.34.56.78 --sport 8767 -m comment --comment "ACC-teamspeak"
   iptables -I INPUT -p tcp -d 12.34.56.78 --dport 25 -m comment --comment "ACC-mailserver"
   iptables -I OUTPUT -p tcp -s 12.34.56.78 --sport 25 -m comment --comment "ACC-mailserver"
   

6. 在/usr/share/munin/plugins/目录下放置插件

   赋予权限 chmod a+x /usr/share/munin/plugins/ipt_accounting_

   执行munin-node-configure --shell

   将输出的ln语句以root权限执行

   编辑/etc/munin/plugin-conf.d/munin-node，加入

   [ipt_accounting_*]
   user root
