　　本文介绍完整的nagios和centreon安装过程。
　　安装环境：

　　CentOS5.6，X64 updated。
　　Monitor Engine:Nagios
　　Broker module:NDoutils
　　假设：
　　已安装并启动mysql
　　路径为：/usr/local/mysql/
　　sock路径：/var/lib/mysql/mysql.sock
　　步骤参考英文原文：http://documentation.centreon.com/docs/centreon/en/latest/installation/from_sources.html
　　1、下载安装包

　　#下载nagios、nagios-plugin、nrpe、ndoutils以及ndoutils的一个patch

1	cd/data/tool

1 2 3 4 5

wget http://prdownloads.sourceforge.net/sourceforge/nagios/nagios-3.5.1.tar.gz wget --no-check-certificate https://www.nagios-plugins.org/download/nagios-plugins-1.5.tar.gz wget http://jaist.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.15/nrpe-2.15.tar.gz wget http://nchc.dl.sourceforge.net/project/nagios/ndoutils-1.x/ndoutils-1.5.2/ndoutils-1.5.2.tar.gz wget http://svn.centreon.com/trunk/ndoutils-patch/ndoutils1.5.2_light.patch

　　#在 http://www.centreon.com/Content-Products-IT-network-monitoring/supported-software-and-requirements 检查安装centreon所需要的软件包
#下载 centreon 2.4.0

1	wget http://download.centreon.com/index.php?id=4264

　　#安装一些必要的package

1	yum install -y wget httpd php gcc glibc glibc-common gd gd-devel make net-snmp

　　2、开始安装nagios
#建立用户和组

1 2 3 4 5

chattr -i /etc/passwd /etc/shadow /etc/group /etc/gshadow useradd nagios groupadd nagcmd usermod -a -G nagcmd nagios usermod -a -G nagcmd apache

　　#安装 nagios-core

1 2 3 4 5 6 7 8 9 10 11 12

tar-zxvf nagios-3.5.1.tar.gz cdnagios ./configure--prefix=/usr/local/nagios--with-command-group=nagcmd \ --enable-event-broker --enable-embedded-perl --with-perlcache makeall makeinstall makeinstall-init makeinstall-config makeinstall-commandmode makeinstall-webconf cp-R contrib/eventhandlers//usr/local/nagios/libexec/ chown-R nagios:nagios /usr/local/nagios/libexec/eventhandlers

　　#启动 nagios apache

1 2 3

/usr/local/nagios/bin/nagios-v/usr/local/nagios/etc/nagios.cfg /etc/init.d/nagiosstart /etc/init.d/httpdstart

　　#创建nagios用户用于登录

1	htpasswd -c /usr/local/nagios/etc/htpasswd.users nagiosadmin

　　#安装 nagios-plugins

1 2 3 4 5 6 7 8 9

tar -zxvf nagios-plugins-1.5.tar.gz cd ../nagios-plugins-1.5 ./configure --with-nagios-user=nagios \ --with-nagios-group=nagios \ --prefix=/usr/local/nagios \ --enable-redhat-pthread-workaround --with-ipv6=no \ --enable-perl-modules \ --with-mysql=/usr/local/mysql make && make install

　　#安装nrpe

1 2 3 4 5 6 7

tar-zxvf nrpe-2.15.tar.gz ./configure--prefix=/usr/local/nagios makeall makeinstall-plugin makeinstall-daemon makeinstall-daemon-config makeinstall-xinetd

　　安装xinetd以便管理

1 2 3 4

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

1 2	/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.cfg

　　3、安装 ndoutils

1 2 3 4

tar-zxvf ndoutils-1.5.2.tar.gz cdndoutils-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

1 2 3 4

sed-i -e 's/#include /#include /'include/config.h sed-i -e 's/#include /#include /'include/config.h make makeinstall

1 2	cp./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

1	broker_module=/usr/local/nagios/bin/ndomod-3x.o config_file=/usr/local/nagios/etc/ndomod.cfg

　　#安装启动文件

1 2	chmod+x daemon-init cpdaemon-init /etc/init.d/ndo2db

　　#创建数据库用户

1 2 3 4

mysql -p >>createdatabasenagios; GRANTALLPRIVILEGESONnagios.* TO'nagios'@'localhost'IDENTIFIED BY'nagios'; >>FLUSH PRIVILEGES;

　　#安装数据库

1 2	cddb/ ./installdb-u nagios -p nagios -h localhost -d nagios

　　4、安装 centreon

1 2 3 4 5 6 7 8 9 10 11 12 13 14 15

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 wget http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt rpm --importRPM-GPG-KEY.dag.txt rpm -ivh rpmforge-release-0.5.1-1.el5.rf.x86_64.rpm yum clean all yum update yum upgrade yum installhttpd gd fontconfig-devel libjpeg-devel libpng-devel gd-devel perl-GD \ openssl-devel perl-DBD-MySQL mysql-server mysql-devel php php-mysql php-gd php-ldap php-xml php-mbstring \ perl-Config-IniFiles perl-DBI perl-DBD-MySQL rrdtool perl-rrdtool perl-Crypt-DES perl-Digest-SHA1 \ perl-Digest-HMAC net-snmp-utils perl-Socket6 perl-IO-Socket-INET6 net-snmp net-snmp-libs php-snmp \ dmidecode lm_sensors perl-Net-SNMP net-snmp-perl fping cpp gcc gcc-c++ libstdc++ glib2-devel \ php-pear

1 2 3 4

usermod-U apache pear channel-update pear.php.net peardev upgrade-all pear upgrade-all

　　报错处理：[PHP Fatal error: Allowed memory size of 8388608 bytes exhausted]

1	echo'memory_limit = 256M'>>/etc/php.ini

　　#开始安装centreon

1	./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

1 2	/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

1 2 3 4

GRANTALLPRIVILEGESON`centreon`.* TO'centreon'@'localhost'identified by'centreon'; GRANTALLPRIVILEGESON`centreon_storage`.* TO'centreon'@'localhost'identified by'centreon'; GRANTALLPRIVILEGESON`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。
