Centreon是开源的IT监控软件，由法国人于2003年开发，最初名为Oreon，并于2005年正式更名为centreon。
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-internetbaseurl=http://centos.ustc.edu.cn/centos/6/os/x86_64/#中科大yum源enabled=1gpgcheck=0
2）安装包下载
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： 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 startservice mysqld startmysqladmin -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.gztar xf nagios-3.4.4.tar.gz./configure --with-nagios-user=nagios --with-nagios-group=nagiosmake allmake installmake install-init && make install-commandmode && make install-config && make install-webconf
Nagios-plugins安装：
tar xf nagios-plugins-1.5.tar.gzcd nagios-plugins-1.5./configure --prefix=/usr/local/nagios/ --with-nagios-user=nagios --with-nagios-group=nagiosmakemake 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selinuxsed -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.gzcd ndoutils-1.5.2./configure --prefix=/usr/local/nagios --with-mysql-lib=/usr/lib/mysql --with-mysql-inc=/usr/include/mysqlmakecp 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.cfgcp config/ndomod.cfg-sample /usr/local/nagios/etc/ndomod.cfgchown nagios.nagios /usr/local/nagios/bin/* /usr/local/nagios/etc/ndo*vim /usr/local/nagios/etc/ndo2db.cfg-------------------------------------------------------------------------------------------------- 120 db_user=nagios 121 db_pass=123456mysql -uroot mysql> create database nagios; mysql> grant all on nagios.* to nagios@localhost identified by '123456'; mysql> flush privileges; mysql> qmysql -unagios -p123456 nagios < db/mysql.sqlvim /usr/local/nagios/etc/nagios.cfg-------------------------------------------------------------------------------------------------- 219 event_broker_options=-1 220broker_module=/usr/local/nagios/bin/ndomod3x.o config_file=/usr/local/nagios/etc/ndomod.cfg #增加本行代码/usr/local/nagios/bin/ndo2db-3x -c /usr/local/nagios/etc/ndo2db.cfg
RRDTool安装：
tar xf rrdtool-1.4.7.tar.gzcd rrdtool-1.4.7./configure --prefix=/usr/local/rrdtool && make && make install
四、Centreon安装
chmod o=rwx /usr/local/centreon/logtar -zxvf centreon-2.4.0.tar.gzcd centreon-2.4.0./install.sh -iDo you accept GPL license ?[y/n], default to [n]:> y------------------------------------------------------------------------ Please choose what you want to install------------------------------------------------------------------------Do you want to install : Centreon Web Front[y/n], default to [n]:> yDo you want to install : Centreon CentCore[y/n], default to [n]:> yDo you want to install : Centreon Nagios Plugins[y/n], default to [n]:> yDo you want to install : Centreon Snmp Traps process[y/n], default to [n]:> y------------------------------------------------------------------------ Start CentWeb Installation------------------------------------------------------------------------Where is your Centreon directory?default to [/usr/local/centreon]>Path /usr/local/centreon OKWhere is your Centreon log directorydefault to [/usr/local/centreon/log]>Path /usr/local/centreon/log OKWhere is your Centreon etc directorydefault to [/etc/centreon]>Path /etc/centreon OKWhere is your Centreon binaries directorydefault to [/usr/local/centreon/bin]>Path /usr/local/centreon/bin OKWhere is your Centreon data informations directorydefault to [/usr/local/centreon/data]>Path /usr/local/centreon/data OKWhere is your Centreon generation_files directory?default to [/usr/local/centreon]>Path /usr/local/centreon OKWhere is your Centreon variable library directory?default to [/var/lib/centreon]>Path /var/lib/centreon OKWhere is your CentPlugins Traps binarydefault to [/usr/local/centreon/bin]>Path /usr/local/centreon/bin OKWhere is the RRD perl module installed [RRDs.pm]default to [/usr/lib/perl5/RRDs.pm]> /usr/local/rrdtool/lib/perl/5.10.1/i386-linux-thread-multi/RRDs.pmPath /usr/local/rrdtool/lib/perl/5.10.1/i386-linux-thread-mOKti/usr/bin/rrdtool OK/bin/mail OK/usr/bin/php OK/usr/bin/perl OKFinding Apache user : apacheFinding Apache group : apacheWhat is the Centreon group ?
