centos7編譯安裝的程序無法用systemctl 啟動
[root@nagios-server check_commands]# systemctl enable npcd.service npcd.service is not a native service, redirecting to /sbin/chkconfig. Executing /sbin/chkconfig npcd on
只需要做個對應的軟鏈接就可以了
[root@nagios-server check_commands]# ln -s /usr/local/pnp4nagios/bin/npcd /sbin/npcd
