0.配置安装包
[[email protected] ~]# yum install -y nagios-server-addons
1.配置监控指向文件
这里要让每个被监控节点都指向监控站点，同时重启服务。
[[email protected] ~]# vim /etc/nagios/nrpe.cfg
[[email protected] ~]# systemctl restart nrpe
[[email protected] ~]# vim /etc/nagios/nrpe.cfg
[[email protected] ~]# systemctl restart nrpe
[[email protected] ~]# vim /etc/nagios/nrpe.cfg
[[email protected] ~]# systemctl restart nrpe
[[email protected] ~]# vim /etc/nagios/nrpe.cfg
[[email protected] ~]# systemctl restart nrpe
2.配置集群监控
选中集群中的一个节点，让系统自动识别。
[[email protected] ~]# configure-gluster-nagios -c gluster-test -H servera.lab.example.com
