#下载 centreon 2.4.0wget http://download.centreon.com/index.php?id=4264#安装一些必要的package
yum install -y wget httpd php gcc glibc glibc-common gd gd-devel make net-snmp2、开始安装nagios
#建立用户和组
chattr -i /etc/passwd /etc/shadow /etc/group /etc/gshadow

groupadd nagcmd
usermod -a -G nagcmd nagios
usermod -a -G nagcmd apache#安装 nagios-core

make && make install#安装nrpe
tar -zxvf nrpe-2.15.tar.gz
./configure --prefix=/usr/local/nagios
make all
make install-plugin
make install-daemon
make install-daemon-config
make install-xinetd　　安装xinetd以便管理
yum install xinetd -y
sed -i 's/127.0.0.1/127.0.0.1 183.61.70.34/' /etc/xinetd.d/nrpe
sed -i '578 i\nrpe            5666/tcp                        # NRPE' /etc/services
service xinetd restart/usr/local/nagios/libexec/check_nrpe -H localhost -c check_users
sed -i 's/allowed_hosts=127.0.0.1/allowed_hosts=127.0.0.1,/' /usr/local/nagios/etc/nrpe.cfg3、安装 ndoutils
tar -zxvf ndoutils-1.5.2.tar.gz
cd ndoutils-1.5.2
patch -p1 -N < ../ndoutils1.5.2_light.patch
./configure --prefix=/usr/local/nagios/ --enable-mysql --with-mysql=/usr/local/mysql --with-ndo2db-user=nagios --with-ndo2db-group=nagios        默认的源文件 make 会报错 修改如下
sed -i -e 's/#include /#include /' include/config.h
sed -i -e 's/#include /#include /' include/config.h
make
make installcp ./config/ndo2db.cfg-sample /usr/local/nagios/etc/ndo2db.cfg
cp ./config/ndomod.cfg-sample /usr/local/nagios/etc/ndomod.cfg        #编辑/usr/local/nagios/etc/nagios.cfg 在broker_module处添加
broker_module=/usr/local/nagios/bin/ndomod-3x.o config_file=/usr/local/nagios/etc/ndomod.cfg　　#安装启动文件
chmod +x daemon-init
cp daemon-init /etc/init.d/ndo2db　　      #创建数据库用户  

mysql -p
>>create database nagios;
GRANT ALL PRIVILEGES ON nagios.* TO 'nagios'@'localhost' IDENTIFIED BY 'nagios';
>>FLUSH PRIVILEGES;　　      #安装数据库

cd db/
./installdb -u nagios -p nagios -h localhost -d nagios4、安装 centreon
usermod -a -G apache centreon
usermod -a -G nagios centreon
wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm

　　        报错处理：[PHP Fatal error:  Allowed memory size of 8388608 bytes exhausted]
echo 'memory_limit = 256M' >>/etc/php.ini　　#开始安装centreon
./install.sh -i　　#经过一系列回车（保持默认配置）以及需要填写的路径完成命令行下的centreon安装。
　　#此处不一一贴出

　　#需要注意的两个路径RRDs.pm、PEAR.php 可使用find 找到准确路径

/usr/local/rrdtool/lib/perl/5.8.8/x86_64-linux-thread-multi/RRDs.pm
/usr/share/pear/PEAR.php　　#配置centreon数据库用户

GRANT ALL PRIVILEGES ON `centreon`.* TO 'centreon'@'localhost' identified by 'centreon';
GRANT ALL PRIVILEGES ON `centreon_storage`.* TO 'centreon'@'localhost' identified by 'centreon';
GRANT ALL PRIVILEGES ON `centreon_status`.* TO 'centreon'@'localhost' identified by 'centreon';
FLUSH PRIVILEGES;
　　#登录web界面进行下一步安装：
　　http://SERVER_ADDRESS/centreon
　　#检查php拓展

　　#配置Nagios相关路径

　　#配置NDoutils路径

　　#管理员账户密码

　　#数据库连接信息

　　#开始安装数据库

　　#安装完成可登录

　　

　　以上为centreon安装完整步骤，坑稍微有点多。

　　特别是centreon命令行模式安装时每个路径、文件名都不要写错。
