nagios客户端安装-添加服务1(不需要nrpe支持)
[root@localhost ~]# yum install -y epel-release ; yum install -y nagios-plugins nagios-plugins-all nrpe nagios-plugins-nrpe
[root@localhost ~]# vi /etc/nagios/nrpe.cfg
allowed_hosts=127.0.0.1,192.168.10.29
dont_blame_nrpe=1
以下在服务端操作
[root@localhost ~]# vi /etc/nagios/conf.d/192.168.10.39.cfg
define host {
use linux-server
host_name 192.168.10.39

}
[root@localhost ~]# /etc/init.d/nagios restart
nagios客户端安装-添加服务2(需要nrpe支持)
以下在服务端操作
[root@localhost ~]# vi /etc/nagios/objects/commands.cfg
define command {
command_name check_nrpe
command_line $USER1$/check_nrpe -H $HOSTADDRESS$ -c $ARG1$
}
[root@localhost ~]# vi /etc/nagios/conf.d/192.168.10.39.cfg
define host {
use linux-server

service_description check_disk_sda1
check_command check_nrpe!check_sda1
max_check_attempts 5
normal_check_interval 1
}
[root@localhost ~]# /etc/init.d/nagios restart
[root@localhost ~]# /etc/init.d/nrpe restart
以下在客户端操作
[root@localhost ~]# vi /etc/nagios/nrpe.cfg
command[check_sda1]=/usr/lib/nagios/plugins/check_disk -w 20% -c 10% -p /dev/sda1
[root@localhost ~]# /etc/init.d/nrpe restart
至此，nagios搭建完毕
