使用Centreon管理Nagios教程之Nagios和Centreon安装

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

cd /data/tool

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

wget 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-snmp

2、开始安装nagios
#建立用户和组

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

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

#启动 nagios apache

/usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg
/etc/init.d/nagios start
/etc/init.d/httpd start

#创建nagios用户用于登录    

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

#安装 nagios-plugins

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

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,<your ip addr>/' /usr/local/nagios/etc/nrpe.cfg

3、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 <mysql\/mysql.h>/#include <\/usr\/local\/mysql\/include\/mysql.h>/' include/config.h
sed -i -e 's/#include <mysql\/errmsg.h>/#include <\/usr\/local\/mysql\/include\/errmsg.h>/' include/config.h
make
make install

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

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 nagios

4、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
wget http://dag.wieers.com/rpm/packages/RPM-GPG-KEY.dag.txt
rpm --import RPM-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 install httpd 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

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]

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。
