centreon作為nagios的分布式監控管理平臺，其功能之強大，打造了centreon在IT監控方面強勢地位，它的底層使用nagios監控軟件，nagios通過ndoutil模塊將監控數據寫入數據庫，centreon讀取該數據并即時的展現監控信息，通過centreon可以簡單地管理和配置所有nagios，因此，完全可以使用centreon輕易的搭建企業級分布式IT基礎運維監控系統。

一、準備工作：
1）配置yum源
最好保證此主機能上Internet，因為光盤內的安裝包有些版本比較舊，還有一部分安裝包沒有，所以如果把光盤作為yum源，會在后面的安裝過程中碰到一些麻煩。
[root@Domain01 ~]# cat /etc/yum.repos.d/rhel-internet.repo [rhel-internet] name=rhel-internet baseurl=http://centos.ustc.edu.cn/centos/6/os/x86_64/#中科大yum源 enabled=1 gpgcheck=0
2）安裝包下載
http://pan.baidu.com/s/1qWLefKS
以上連接中包括Nagios，Nagios-Plugins，Centreon，RRDtool，ndoutils源碼安裝包
二、LAMP環境搭建
如果網絡環境好，且硬盤足夠大建議最大化安裝，因為這樣可以最大化的避免源碼安裝過程中找不到庫文件，centreon配置時找不到對應文件的尷尬。
安裝之前先安裝開發包組：
yum -y groupinstall "Development tools" yum -y install gd gd-devel
最大化安裝LAMP：
yum -y install httpd* yum -y install mysql* yum -y install php*
由于安裝文件比較多，這幾步視網絡情況可能要花幾分鐘時間，期間可以上個廁所，沏杯茶，或者刷耍微博之類的。
如果在安裝過程中出現以下錯誤：
Error Downloading Packages: bcel-5.2-7.2.el6.x86_64: failure: Packages/bcel-5.2-7.2.el6.x86_64.rpm from rhel-internet: [Errno 256] No more mirrors to try.
請下載對應的安裝包后安裝，bcel的rpm包：http://rpm.pbone.net/index.php3?stat=26&dist=74&size=1426424&name=bcel-5.2-7.2.el6.x86_64.rpm 右鍵另存為即可。
安裝過程中如存在依賴關系請使用yum安裝：
yum -y install bcel-5.2-7.2.el6.x86_64.rpm
安裝完成后記得將httpd，mysqld，加入開機啟動中：
[root@Domain01 ~]# chkconfig httpd on [root@Domain01 ~]# chkconfig mysqld on
開啟httpd服務并測試：
service httpd start service mysqld start mysqladmin -uroot password 123456
看到如下界面說明安裝成功
三、Nagios及相關插件安裝
Nagios安裝：
useradd -s /sbin/nologin -G apache nagios #增加Nagios用戶，并將其加入apache組中 tar xf nagios-3.4.4.tar.gz tar xf nagios-3.4.4.tar.gz ./configure --with-nagios-user=nagios --with-nagios-group=nagios make all make install make install-init && make install-commandmode && make install-config && make install-webconf
Nagios-plugins安裝：
tar xf nagios-plugins-1.5.tar.gz cd nagios-plugins-1.5 ./configure --prefix=/usr/local/nagios/ --with-nagios-user=nagios --with-nagios-group=nagios make make install
相關配置：
創建Nagios web登錄用戶并設置密碼
htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
防火墻和Selinux設置：
iptables -F #清除防火墻規則，生產環境慎用 iptables -A INPUT -p tcp --dport 80 -j ACCEPT #開啟80端口 setenforce 0 #關閉selinux sed -i s/SELINUX=enforcing/SELINUX=disabled/g /etc/sysconfig/selinux #在配置文件中永久關閉selinux
ndoutils安裝
tar xf ndoutils-1.5.2.tar.gz
cd ndoutils-1.5.2
./configure --prefix=/usr/local/nagios --with-mysql-lib=/usr/lib/mysql --with-mysql-inc=/usr/include/mysql
make
cp src/ndo2db-3x src/file2sock src/log2ndo src/ndomod-3x.o /usr/local/nagios/bin/
cp config/ndo2db.cfg-sample /usr/local/nagios/etc/ndo2db.cfg
cp config/ndomod.cfg-sample /usr/local/nagios/etc/ndomod.cfg
chown nagios.nagios /usr/local/nagios/bin/* /usr/local/nagios/etc/ndo*

/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfgRRDTool安裝：
tar xf rrdtool-1.4.7.tar.gz cd rrdtool-1.4.7 ./configure --prefix=/usr/local/rrdtool && make && make install
四、Centreon安裝
chmod o=rwx /usr/local/centreon/log
tar -zxvf centreon-2.4.0.tar.gz
cd centreon-2.4.0
./install.sh -i
