nagios+centreon监控构建

wuyijie

监控系统是运维人员的一个重要工具，熟悉其的构建与应用必不可少。nagios与centreon的搭

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/ ... nagios-3.5.0.tar.gz wget http://download.centreon.com/centreon/centreon-2.4.2.tar.gz wget http://nchc.dl.sourceforge.net/p ... ugins-1.4.16.tar.gz wget http://nchc.dl.sourceforge.net/p ... outils-1.5.2.tar.gz wget http://svn.centreon.com/trunk/nd ... ls1.5.2_light.patch wget http://nchc.dl.sourceforge.net/p ... 14/nrpe-2.14.tar.gz

2.安装第三方源

[iyunv@localhost ~]# wget http://packages.sw.be/rpmforge-r ... 2-1.el6.rf.i686.rpm [iyunv@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 [iyunv@localhost ~]# yum -y install httpd [iyunv@localhost ~]# usermod -U apache [iyunv@localhost ~]# service httpd start [iyunv@localhost ~]# yum install mysql-devel openssl-devel mysql-server [iyunv@localhost ~]# service mysqld start [iyunv@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 [iyunv@localhost ~]# yum -y install php php-mysql php-gd php-ldap php-xml php-mbstring [iyunv@localhost ~]# yum -y install gd fontconfig-devel libjpeg-devel libpng-devel gd-devel perl-GD RRDTools [iyunv@localhost ~]# yum -y install rrdtool perl-rrdtool 安装perl [iyunv@localhost ~]# yum -y install perl-Config-IniFiles perl-DBI perl-DBD-MySQL 安装SNMP [iyunv@localhost ~]# yum -y install perl-Crypt-DES perl-Digest-SHA1 perl-Digest-HMAC net-snmp-utils [iyunv@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 [iyunv@localhost ~]# yum -y install php-pear [iyunv@localhost ~]# pear channel-update pear.php.net [iyunv@localhost ~]# pear install --force PEAR-1.9.1 [iyunv@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 [iyunv@localhost ~]# useradd -m nagios [iyunv@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。 [iyunv@localhost ~]# groupadd nagcmd [iyunv@localhost ~]# usermod -G nagios,nagcmd nagios [iyunv@localhost ~]# usermod -G nagios,nagcmd apache 安装nagios [iyunv@localhost monitor]# tar -zxvf nagios-3.5.0.tar.gz [iyunv@localhost nagios]# ./configure --prefix=/usr/local/nagios --with-command-group=nagcmd --enable-nanosleep --enable-event-broker --enable-embedded-perl [iyunv@localhost nagios]# make all [iyunv@localhost nagios]# make install [iyunv@localhost nagios]# make install-init [iyunv@localhost nagios]# make install-commandmode [iyunv@localhost nagios]# make install-config [iyunv@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

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

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

web安装

(1)centreon的欢迎界面

(2)检查依赖关系

(3)配置nagios信息

(4)配置ndoutils模块

(5)配置admin用户

(6)配置数据库信息

(7)安装

(8)安装完成

5.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。

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

三.后续登录错误

1.错误信息

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

四.检查重新生成配置文件

(1)检查main.cfg的配置

(2)检查ndo2db.cfg的配置

(3)检查ndomod.cfg的配置

(4)生成nagios配置文件

web页面重启完成后，查看nagios相关日志

[iyunv@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。
