重启Nagios时报错“Failed to restart nagios.service: Unit not found”

 

问题：

执行完命令 /usr/local/nagios/bin/nagios -v /usr/local/nagios/etc/nagios.cfg 后重启Nagios报错

[root@CentOs nagios-plugins-2.2.1]# systemctl restart nagios.service

 

 

 

解决方法：

[root@CentOs nagios-plugins-2.2.1]# vim /etc/systemd/system/nagios.service
添加如下内容：

[Unit]
Description=Nagios
BindTo=network.target


[Install]
WantedBy=multi-user.target

[Service]
User=nagios
Group=nagios
Type=simple
ExecStart=/usr/local/nagios/bin/nagios /usr/local/nagios/etc/nagios.cfg

 

之后运行如下命令，即可成功！

[root@CentOs nagios-plugins-2.2.1]# systemctl enable /etc/systemd/system/nagios.service
Created symlink from /etc/systemd/system/multi-user.target.wants/nagios.service to /etc/systemd/system/nagios.service.
