Gcc編譯器 yum install gcc
Glibc函式庫 yum install glibc glibc-common
GD函式庫 yum install gd gd-devel
yum install nagios nagios-plugins-all nrpe
下載Nagios及其Plugins，目前最新穩定版本分別為3.0.6與1.4.13
為了讓Nagios伺服器可以監看遠端Linux主機，需要額外安裝NRPE套件
測試設定檔無誤

yum使用
作者:tseng 日期:2009-04-26
安裝：yum install xxx
移除：yum remove xxx
清除已經安裝過的檔案（/var/cache/yum/）：yum clean all
搜尋：yum search xxx
列出所有檔案：yum list
查詢檔案訊息：yum info xxx
yum grouplist
yum groupinstall "Web Server"
yum check-update;yum -y update;yum clean all
另外，我們在安裝一些要用到的一些工具時，或許它並不存在於 CentOS yum 的官方資料庫中。所以我們還要另外定義非官方資料庫文件，讓一些實用的工具也能透過 yum 來安裝。
# vi /etc/yum.repos.d/dag.repo
[dag]
name=Dag RPM Repository for Red Hat Enterprise Linux
baseurl=http://apt.sw.be/redhat/el$releasever/en/$basearch/dag
gpgcheck=1
enabled=1
http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
匯入非官方資料庫的GPG
# rpm --import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
一、強化yum功能
yum install yum-fastestmirror（加快yum下載速度）
yum install yum-priorities
vi /etc/yum/pluginconf.d/priorities.conf
在 [main]下新增enabled=1 (預設已寫上)
cp /etc/yum.repos.d/CentOS-Base.repo /etc/yum.repos.d/CentOS-Base.repo.bak
vim /etc/yum.repos.d/CentOS-Base.repo
在[base], [addons], [updates], [extras]項目下新增 priority=1
在[centosplus],[contrib]項目下新增 priority=2
/etc/init.d/yum-updatesd restart
二、下載相關套件並安裝（請自行對應）
i386 wget http://apt.sw.be/redhat/el5/en/i386/RPMS.dag/rpmforge-release-0.3.6-1.el5.rf.i386.rpm
x86_64 wget http://apt.sw.be/redhat/el5/en/x86_64/RPMS.dag/rpmforge-release-0.3.6-1.el5.rf.x86_64.rpm
安裝金鑰
rpm --import http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt (備份檔案)
rpm -ivh rpmforge-release-0.3.6-1.el5.rf.i38...
