nginx

我服务器的系统是CentOS7.5 ,在修改Nginx配置后重启Nginx以使用配置生效，我使用了以下命令：

systemctl restart nginx

这次遇到错误：

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

我使用systemctl status nginx命令查看有如下提示：

这个错误怎么解决呢？看样子是由于80端口被占用引起的，可是我没能其它程序使用80端口呢？
正确的解释是nginx自己在重启的过程中资源没有完全释放，我只需要把nginx进程强制关闭才行。
使用如下命令查看进程

# ps -e | grep nginx
