nagios搭建配置

一、环境 ubuntu 14.04系统

host1:172.17.0.2  server
host2:172.17.0.3  client

二、安装

1.在两个主机上都执行一下命令：

#apt-get install update -y
#apt-get install build-essential -y

2.host1上安装nagios服务：

#apt-get install nagios3 nagios-nrpe-plugin -y

	#apt-get install ndoutils-common -y   //需要数据库的支持，执行之前确保mysql已经启动。若没有也可以跳过
	#vim /etc/default/ndoutils	//修改ENABLE_NDOUTILS=1为1.
	#vim /etc/nagios3/nagios.cfg
	添加：broker_module=/usr/lib/ndoutils/ndomod-mysql-3x.o config_file=/etc/nagios3/ndomod.cfg

3.启动NDOUtils和nagios:

#service ndoutils start
#/etc/init.d/nagios3 restart

4.host2安装nagios

#apt-get install nagios-nrpe-server nagios-plugins -y
#vim /etc/nagios/nrpe.cfg
	allowed_hosts=127.0.0.1 172.17.0.2	//添加server的IP
#/etc/init.d/nagios-nrpe-server restart

5.host1配置监控host2的文件：
#vim /etc/nagios3/nagios.cfg
	去掉cfg_dir=/etc/nagios3/servers的注释。
#vim /etc/nagios3/servers/clients.cfg
define host{
	use                             generic-host
	host_name                       host2 hostname
	alias                           host2 hostname
	address                         172.17.0.3
	max_check_attempts              5
	check_period                    24x7
	notification_interval           30
	notification_period             24x7
	}
define service {
    use                             generic-service
    host_name                       host2 hostname
    service_description             SSH
    check_command                   check_ssh
    notifications_enabled           0
    }

#/etc/init.d/nagios3 restart
