MUNIN是一個基於WEB介面的系統監視工具，MUNIN是一個基於WEB介面的系統監視工具。munin主要對系統 網路 磁碟 程序 應用等訪問進行監控。可以很直觀的在圖上的曲線看出執行情況

MUNIN的安裝有2種方式，一個是去munin上下載原始碼進行編譯，不過要解決不少依賴問題。

二是進行yum安裝，這樣可以避免依賴問題。

centos預設情況下不能進行munin的yum安裝。先要安裝yum-priorities 

1;

用於 CentOS 5 安裝源的 yum-priorities 軟體包:

yum install yum-priorities

i386 http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.1-1.el5.rf.i386.rpm

x86_64 http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm

2.

我的centos是64位的，下載如下:

wget http://apt.sw.be/redhat/el5/en/x86_64/rpmforge/RPMS/rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm

3;

rpm -Uvh rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm

#cd /etc/yum.repos.d/

# ls

CentOS-Base.repo CentOS-Base.repo.bak mirrors-rpmforge

CentOS-Base.repo.5 CentOS-Media.repo rpmforge.repo

有了這個RPMforge Repository的源就可以開始yum 安裝munin

4 服務端安裝

#yum install munin munin-node

安裝完畢之後

#cd /etc/munin

# ls

munin.conf munin-node.conf plugins

munin-node.confdafault plugins.conf

plugin-conf.d templates

需要在你web伺服器的靜態目錄中建立一個目錄 munin

#mkdir -p  /usr/local/nginx/html/htdocs/munin/

#chown -R munin:munin /usr/local/nginx/html/htdocs/munin/

簡單設定 munin的配置檔案/etc/munin/munin.conf

vi /etc/munin/munin.conf

dbdir /var/lib/munin

htmldir  /usr/local/nginx/html/htdocs/munin/

logdir /var/log/munin

rundir /var/run/munin

tmpldir /etc/munin/templates

[localhost]

address 127.0.0.1

use_node_name yes

＃新增一個客戶端

[db]

address 172.32.1.1

use_node_name yes

[db2]

address 172.32.1.2

use_node_name yes

設定 munin啟動腳步並啟動 munin

#chkconfig --levels 235 munin-node on

#/etc/init.d/munin-node start

Starting Munin Node: [ OK ]

# ps fax|grep munin

11627 pts/2 S+ 0:00 \_ grep munin

11548 ? Ss 0:00 /usr/sbin/munin-node

#cd /var/log/munin

# ls

munin-graph.log munin-limits.log munin-update.log

munin-html.log munin-node.log

# tail -f /var/log/munin/munin-html.log

5;客戶端安裝,我的客戶端也是centos5.6

在客戶端主機上,只需要安裝munin-node就可以了

當然首先還是得重複一下伺服器端的前面2步
yum install yum-priorities

yum install -y munin-node

cd /etc/munin

vi munin-node.conf

新增服務端的ip

allow ^172\.32\.1\.19$ #這個就是munin主伺服器上的IP,允許這個IP對我的訪問.

#/etc/init.d/munin-node restart

cat /var/log/munin/munin-node.log

在apache/nginx中配置一個虛擬主機

ServerName www.ff-bb.cn

DocumentRoot "/var/www/html/munin"

過幾分鐘，訪問這個域名即可看到資料。
