配是开源软件最佳选择。现在将我的构建与应用过程记录如下。

一.环境预安装

1.获取主软件包

wget http://jaist.dl.sourceforge.net/project/nagios/nagios-3.x/nagios-3.5.0/nagios-3.5.0.tar.gz
wget http://download.centreon.com/centreon/centreon-2.4.2.tar.gz
wget http://nchc.dl.sourceforge.net/project/nagiosplug/nagiosplug/1.4.16/nagios-plugins-1.4.16.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
wget http://nchc.dl.sourceforge.net/project/nagios/nrpe-2.x/nrpe-2.14/nrpe-2.14.tar.gz

2.安装第三方源

[root@localhost ~]# wget http://packages.sw.be/rpmforge-release/rpmforge-release-0.5.2-1.el6.rf.i686.rpm
[root@localhost ~]#rpm -ivh rpmforge-release-0.5.2-1.el6.rf.i686.rpm

如果不安装第三方源会导致相关软件包不能安装，进而导致主安装出现相关问题。

3.安装相关软件包

安装apache

[root@localhost ~]# yum -y install httpd
[root@localhost ~]# usermod -U apache
[root@localhost ~]# service httpd start

[root@localhost ~]# yum install MySQL-devel openssl-devel mysql-server
[root@localhost ~]# service mysqld start
[root@localhost ~]# mysqladmin -u root password '123456'

在/etc/my.conf中的[mysqld]加入

innodb_file_per_table=1

否则在web安装第七步时会有提示。

安装php
[root@localhost ~]# yum -y install php php-mysql php-gd php-ldap php-xml php-mbstring
[root@localhost ~]# yum -y install gd fontconfig-devel libjpeg-devel libpng-devel gd-devel perl-GD

RRDTools
[root@localhost ~]# yum -y install rrdtool perl-rrdtool

安装perl
[root@localhost ~]# yum -y install perl-Config-IniFiles perl-DBI perl-DBD-MySQL

安装SNMP
[root@localhost ~]# yum -y install perl-Crypt-DES perl-Digest-SHA1 perl-Digest-HMAC net-snmp-utils
[root@localhost ~]# yum -y install perl-Socket6 perl-IO-Socket-INET6 net-snmp net-snmp-libs php-snmp dmidecode lm_sensors perl-Net-SNMP net-snmp-perl


安装PEAR
[root@localhost ~]# yum -y install php-pear
[root@localhost ~]# pear channel-update pear.php.net
[root@localhost ~]# pear install --force PEAR-1.9.1
[root@localhost ~]# pear upgrade-all

二. 主软件包安装

nagios主要监控系统与网络信息，同时监控远程与本地主机及相关服务，还提供信息异常功能

1.安装nagios

添加相关用户及组

[root@localhost ~]# useradd -m nagios
[root@localhost ~]# passwd nagios
更改用户 nagios 的密码 。
新的 密码：
无效的密码： 过于简单化/系统化
无效的密码： 过于简单
重新输入新的 密码：
passwd： 所有的身份验证令牌已经成功更新。
[root@localhost ~]# groupadd nagcmd
[root@localhost ~]# usermod -G nagios,nagcmd nagios
[root@localhost ~]# usermod -G nagios,nagcmd apache

安装nagios

[root@localhost monitor]# tar -zxvf nagios-3.5.0.tar.gz
[root@localhost nagios]# ./configure --prefix=/usr/local/nagios --with-command-group=nagcmd --enable-nanosleep --enable-event-broker --enable-embedded-perl
[root@localhost nagios]# make all
[root@localhost nagios]# make install
[root@localhost nagios]# make install-init
[root@localhost nagios]# make install-commandmode
[root@localhost nagios]# make install-config
[root@localhost nagios]# /etc/init.d/nagios start

nagios如果少了其插件，将什么也做不了，其功能主要通过插件来完成的。

2.nagios-pluigns安装

[root@localhost monitor]# tar -zxvf nagios-plugins-1.4.16.tar.gz
[root@localhost nagios-plugins-1.4.16]# ./configure --with-nagios-user=nagios --with-nagios-group=nagios --with-openssl=/usr/bin/openssl --enable-perl-modules
[root@localhost nagios-plugins-1.4.16]# make && make install

3.ndoutils安装

ndoutils主要将相关数据存储到数据库，ndoutils非常重要。

[root@localhost ndoutils-1.5.2]# tar -zxvf ndoutils-1.5.2.tar.gz
[root@localhost ndoutils-1.5.2]# patch -p1 -N < ndoutils1.5.2_light.patch
[root@localhost ndoutils-1.5.2]# ./configure --prefix=/usr/local/nagios/ --enable-mysql --with-ndo2db-user=nagios --with-ndo2db-group=nagios
[root@localhost ndoutils-1.5.2]# make && make install
[root@localhost ndoutils-1.5.2]# cp daemon-init /etc/init.d/ndo2db
[root@localhost ndoutils-1.5.2]# chmod 755 /etc/init.d/ndo2db
[root@localhost ndoutils-1.5.2]# cp config/ndo2db.cfg-sample /usr/local/nagios/etc/ndo2db.cfg
[root@localhost ndoutils-1.5.2]# /etc/init.d/ndoutils start

4.centreon安装

centreon以web方式展现给用户，通过第三方软件实现对网络，应用程序，主机的监控。

注：如下安装过程只做参考，其不是第一次安装 ，与第一次安装可能有所不同，第一次安装时会更新相关模块。

文本安装

[root@localhost monitor]# tar -zxvf centreon-2.4.2.tar.gz


[root@localhost centreon-2.4.2]# ./install.sh -i

web安装

(1)centreon的欢迎界面

nagios+centreon监控构建

(2)检查依赖关系

nagios+centreon监控构建

(3)配置nagios信息

nagios+centreon监控构建

(4)配置ndoutils模块

nagios+centreon监控构建

(5)配置admin用户

nagios+centreon监控构建

(6)配置数据库信息

nagios+centreon监控构建

(7)安装

nagios+centreon监控构建

(8)安装完成

nagios+centreon监控构建

5.服务器端nrpe安装

nrpe是nagios组件，能够执行远程主机的本地检测脚本，监控运行状态。

[root@localhost monitor]# tar -zxvf nrpe-2.14.tar.gz
[root@localhost nrpe-2.14]# ./configure
[root@localhost nrpe-2.14]# make all && make install

服务器端检测错误

[root@nodes01 nrpe-2.12]# /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1
CHECK_NRPE: Error - Could not complete SSL handshake

在/usr/local/nagios/etc/nrpe.cfg加入

allowed_hosts=127.0.0.1,192.168.4.213

[root@nodes01 nrpe-2.12]# /usr/local/nagios/libexec/check_nrpe -H 127.0.0.1
NRPE v2.12
[root@nodes01 nrpe-2.12]# /usr/local/nagios/libexec/check_nrpe -H 192.168.4.213
NRPE v2.12

三.后续登录错误

1.错误信息

nagios+centreon监控构建

2.日志信息

25/4/2013 18:36:01 - 25/4/2013 18:36:1 - DBI connect('database=centreon_storage;host=localhost:3306','centreon',...) failed: Access denied for user 'centreon'@'localhost' to database 'centreon_storage' at /usr/local/centreon/bin/logAnalyser line 596

3.解决方法

mysql> grant all on centreon.* to centreon@localhost identified by '123456';
Query OK, 0 rows affected (0.07 sec)

mysql> grant all on centreon_status.* to centreon@localhost identified by '123456';
Query OK, 0 rows affected (0.00 sec)

mysql> grant all on centreon_storage.* to centreon@localhost identified by '123456';
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.06 sec)

成功页面如下

nagios+centreon监控构建

四.检查重新生成配置文件

(1)检查main.cfg的配置

nagios+centreon监控构建

(2)检查ndo2db.cfg的配置

nagios+centreon监控构建

(3)检查ndomod.cfg的配置

nagios+centreon监控构建

(4)生成nagios配置文件

nagios+centreon监控构建

web页面重启完成后，查看nagios相关日志

[root@localhost ~]# tail -f /usr/local/nagios/var/nagios.log | grep ndomod
[1366898324] ndomod: Successfully connected to data sink. 122 queued items to flush.
[1366898324] ndomod: Successfully flushed 122 queued items to data sink.

如果有以上信息代表成功，因为ndoutils是nagios与centreon的纽带，必须保证其正常运行。

centreon的服务器端已经配置完成，对于其被监控主机上也安装nagios-plugins和nrpe软件包，这里就不再重复，centreon的应用配置及汉化后续再出。
