centos7编译安装的程序无法用systemctl 启动
[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
只需要做个对应的软链接就可以了
[root@nagios-server check_commands]# ln -s /usr/local/pnp4nagios/bin/npcd /sbin/npcd
