Nginx升级后启动错误

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

根据错误 提示 执行命令 ： 

systemctl status nginx.service

然后 提示：

[root@VM_0_3_centos ~]# systemctl status nginx.service

根据提示： ExecStart=/usr/sbin/nginx (code=exited, status=1/FAILURE) （重点在此）

执行：

/usr/sbin/nginx -c /etc/nginx/nginx.conf

ok 正常了。

重新启动：

systemctl start nginx

一切正常。
