搭建ICINGA监控

一、环境：

OS: CentOS 6.2 Minimal

IP: 172.16.51.9

HOSTNAME: icinga.hqew.com

二、搭建

源码包存放位置：/usr/local/src

1、安装基本软件包

# yum install -y make automake gcc-c++ httpd gcc glibc glibc-common gd gd-devel libjpeg libjpeg-devel libpng libpng-devel mysql mysql-server libdbi libdbi-devel libdbi-drivers libdbi-dbd-mysql

关闭防火墙，禁用selinux

# chkconfig iptables off >> service iptables stop
# sed -i 's/SELINUX=enforcing/SELINUX=disabled/' /etc/selinux/config

2、下载icinga源码包及nagios插件

# cd /usr/local/src
# wget -c http://cdnetworks-kr-1.dl.sourceforge.net/project/icinga-cn/icinga-cn/icinga-cn-1.7.0/icinga-cn-1.7.0.tar.xz
# wget -c http://cdnetworks-kr-1.dl.sourceforge.net/project/nagiosplug/nagiosplug/1.4.15/nagios-plugins-1.4.15.tar.gz

3、创建icinga用户

# useradd – m icinga
# passwd icinga
# groupadd icinga-cmd
# usermod -a -G icinga-cmd icinga
# usermod -a -G icinga-cmd apache

4、编译安装icinga

# yum install -y xz
# xz -d icinga-cn-1.7.0.tar.xz
# tar xf icinga-cn-1.7.0.tar
# cd icinga-cn-1.7.0
# ./configure --with-command-group=icinga-cmd –enable-idoutils
# make all
# make install
# make install-init
# make install-config
# make install-eventhandlers
# make install-commandmode

或者更简便：

# make fullinstall
# make install-config

5、编辑警报联系人

# vi /usr/local/icinga/etc/objects/contacts.cfg

6、启用idomod event broker module

# cd /usr/local/icinga/etc/module
# cp idoutils.cfg-sample idoutils.cfg
# chown icinga.icinga idoutils.cfg

7、创建数据库

# service mysqld start
# mysql

mysql> drop database test;
Query OK, 0 rows affected (0.00 sec)

mysql> use mysql
Reading table information for completion of table and column names
You can turn off this feature to get a quicker startup with -A

Database changed
mysql> delete from user where user='';
Query OK, 2 rows affected (0.00 sec)

mysql> update user set password=password('123456') where user='root';
Query OK, 3 rows affected (0.00 sec)
Rows matched: 3 Changed: 3 Warnings: 0

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> create database icinga;
Query OK, 1 row affected (0.00 sec)

mysql> grant usage on *.* to icinga@localhost identified by 'icinga' with MAX_QUERIES_PER_HOUR 0 MAX_CONNECTIONS_PER_HOUR 0 MAX_UPDATES_PER_HOUR 0;
Query OK, 0 rows affected (0.00 sec)

mysql> grant select,insert,update,delete,drop,create view on icinga.* to icinga@localhost;
Query OK, 0 rows affected (0.00 sec)

mysql> flush privileges;
Query OK, 0 rows affected (0.00 sec)

mysql> q

8、导入数据库

# mysql -p icinga < /usr/local/src/icinga-cn-1.7.0/module/idoutils/db/mysql
Enter password:
ERROR 1273 (HY000) at line 627: Unknown collation: 'utf8_general_cs'

解决：

编辑mysql.sql，删除utf8_geneal_cs，共有四个，然后重新导入。

9、配置ido2db.cfg

# vi /usr/local/etc/icinga/etc/ido2db.cfg

确保如下内容

db_servertype=mysql
db_port=3306
db_user=icinga
db_pass=icinga

10、配置Classic Web界面

# cd /usr/local/src/icinga-cn-1.7.0
# make cgis
# make install-cgis
# make install-html
# make install-webconf

11、启动httpd服务

# chkconfig httpd on >> service httpd start

12、编译安装Nagios插件

# cd /usr/local/src
# tar xf nagios-plugins-1.4.15.tar.gz
# cd nagios-plugins-1.4.15
# ./configure --prefix=/usr/local/icinga/ --with-cgiurl=/icinga/cgi-bin --with-htmurl=/icinga -with-nagios-user=icinga –with-nagios-group=icinga
# make >> make install

13、启动idoutils和icinga

# service ido2db start
# service icinga start
# chkconfig –add icinga >> chkconfig icinga on

PS:

启动icinga之前可以先测试一下配置文件

# /usr/local/icinga/bin/icinga -v /usr/local/icinga/etc/icinga.cfg

编译安装nrpe

# cd /usr/local/src
# wget -c http://cdnetworks-kr-1.dl.sourceforge.net/project/icinga-cn/nrpe-icinga/nrpe-icinga-2.12.tar.bz2
# tar xf nrpe-icinga-2.12.tar.bz2
# ./configure
checking for SSL headers... configure: error: Cannot find ssl headers
解决方法：
# yum install openssl openssl-devel -y
# make all

Makefile:86: *** missing separator. Stop.

解决：

编辑Makefile，删除85－92行（判断操作系统）

# vi Makefile
# make all
# make install
# make install-plugin
# make install-init
# make install-xinetd
# make install-daemon-config

测试

# /usr/local/icinga/libexec/check_nrpe -H 127.0.0.1
NRPE v2.12
# /usr/local/icinga/libexec/check_nrpe -H 172.16.51.7
CHECK_NRPE: Error - Could not complete SSL handshake.

解决：

配置被监控linux主机

# vi /usr/local/icinga/etc/nrpe.cfg
allowed_hosts=127.0.0.1,172.16.51.9
# /etc/init.d/icinga-nrpe restart
# /usr/local/icinga/libexec/check_nrpe -H 172.16.51.7
NRPE v2.12
