centreon作为nagios的分布式监控管理平台，其功能之强大，打造了centreon在IT监控方面强势地位，它的底层使用nagios监控软件，nagios通过ndoutil模块将监控数据写入数据库，centreon读取该数据并即时的展现监控信息，通过centreon可以简单地管理和配置所有nagios，因此，完全可以使用centreon轻易的搭建企业级分布式IT基础运维监控系统。

一、准备工作：
1）配置yum源
最好保证此主机能上Internet，因为光盘内的安装包有些版本比较旧，还有一部分安装包没有，所以如果把光盘作为yum源，会在后面的安装过程中碰到一些麻烦。
[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）安装包下载
http://pan.baidu.com/s/1qWLefKS
以上连接中包括Nagios，Nagios-Plugins，Centreon，RRDtool，ndoutils源码安装包
二、LAMP环境搭建
如果网络环境好，且硬盘足够大建议最大化安装，因为这样可以最大化的避免源码安装过程中找不到库文件，centreon配置时找不到对应文件的尴尬。
安装之前先安装开发包组：
yum -y groupinstall "Development tools" yum -y install gd gd-devel
最大化安装LAMP：
yum -y install httpd* yum -y install MySQL* yum -y install php*
由于安装文件比较多，这几步视网络情况可能要花几分钟时间，期间可以上个厕所，沏杯茶，或者刷耍微博之类的。
如果在安装过程中出现以下错误：
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.
请下载对应的安装包后安装，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 右键另存为即可。
安装过程中如存在依赖关系请使用yum安装：
yum -y install bcel-5.2-7.2.el6.x86_64.rpm
安装完成后记得将httpd，mysqld，加入开机启动中：
[root@Domain01 ~]# chkconfig httpd on [root@Domain01 ~]# chkconfig mysqld on
开启httpd服务并测试：
service httpd start service mysqld start mysqladmin -uroot password 123456
看到如下界面说明安装成功
三、Nagios及相关插件安装
Nagios安装：
useradd -s /sbin/nologin -G apache nagios #增加Nagios用户，并将其加入apache组中 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安装：
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
相关配置：
创建Nagios web登录用户并设置密码
htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin
防火墙和Selinux设置：
iptables -F #清除防火墙规则，生产环境慎用 iptables -A INPUT -p tcp --dport 80 -j ACCEPT #开启80端口 setenforce 0 #关闭selinux sed -i s/SELINUX=enforcing/SELINUX=disabled/g /etc/sysconfig/selinux #在配置文件中永久关闭selinux
ndoutils安装
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

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