Nginx重启失败 Active: failed (Result: exit-code)

nginx重启失败，但没有错误日志，一行提示失败

Redirecting to /bin/systemctl restart nginx.service

Job for nginx.service failed because the control process exited with error code. See "systemctl status nginx.service" and "journalctl -xe" for details.

可以看到，通过提示的命令 systemctl status nginx.service 来查看日志。

/捂脸 ~~~ 根本没有具体错误信息，一番尝试，可能是80 或者 443 端口被占用了，启动不了。

执行以下两条命令，先把占用80/443的进度干掉

sudo fuser -k 80/tcp
sudo fuser -k 443/tcp

然后重启nginx，sudo service nginx restart
