(详细配置请查看我的另一篇文章:http://blog.51cto.com/12173069/2070827)
Nagios安装 - 服务端(192.168.8.81)
安装nagios相关的包yum -y install nagios nagios-plugins nagios-plugins-all nagios-plugins-nrpe nrpe
设置登录nagios后台的用户和密码:
htpasswd -c /etc/nagios/passwd lee
改变nagios相关目录权限:
chown nagios.nagios /etc/logrotate.d/nagios chmod g+w /etc/logrotate.d/nagios chown -R nagios.nagios /etc/nagios vim /etc/nagios/nagios.cfg(nagios主配置文件) nagios -v /etc/nagios/nagios.cfg 检测主配置文件的语法
启动服务:
systemctl start httpd systemctl start nagios
浏览器访问: 192.168.8.81/nagios
- Nagios安装 - 客户端(192.168.8.82)
安装nrpe服务yum -y install nagios-plugins nagios-plugins-nrpe nrpe
修改 nrpe 主配置文件:vim /etc/nagios/nrpe.cfg
找到“allowed_hosts=127.0.0.1” 改为 “allowed_hosts=127.0.0.1,192.168.8.81” 后面的ip为服务端ip
修改/etc/hosts.allow增加监控机ip:echo 'nrpe:192.168.8.82' >> /etc/hosts.allow
查看 nrpe 端口是否开启:
netstat -nutlp | grep 5666
启动客户端
systemctl start nrpe
- 在服务端添加客户端主机(192.168.8.82)
添加命令:vim /etc/nagios/objects/commands.cfgdefine command{ command_name check_nrpe command_line $USER1/check_nrpe -H $HOSTADDRESS -c $ARG1 }
vim /etc/nagios/conf.d/lee.cfg
//加入:define host{ use linux-server host_name lee alias lee address 192.168.8.82 } define service{ use generic-service host_name lee service_description load check_command check_nrpe!check_load } define service{ use generic-service host_name lee service_description PING check_command check_ping!100.0,20%!200.0,50% max_check_attempts 5 check_interval 1 } define service{ use generic-service host_name lee service_description FTP check_command check_ftp!21 max_check_attempts 5 check_interval 1 } define service{ use generic-service host_name lee service_description SSH check_command check_ssh max_check_attempts 5 check_interval 1 } define service{ use generic-service host_name lee service_description HTTP check_command check_http max_check_attempts 5 check_interval 1 }
- 最后加上个配置成功后的画面:
