在 Debian9 上启动 nginx 时遇到问题

我在debian9上安装了nginx-full，但无法启动。当我这样做的时候。

sudo /etc/init.d/nginx start

我有

[....] Starting nginx (via systemctl): nginx.serviceJob for nginx.service failed because the control process exited with error code.
See "systemctl status nginx.service" and "journalctl -xe" for details.
failed!

我也尝试过 sudo nginx -t 并且得到了

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

systemctl status nginx.service 的输出是：

$sudo systemctl status nginx.service

查看 的输出systemctl status nginx.service，似乎运行 nginx 的端口正在被其他进程使用。

您可以使用netstat -tulpn|grep 80命令进行检查。一旦确定，

(1) 更改端口号。通过使用编辑器进行编辑并设置并nginx启动( )或/etc/nginx/nginx.conf'Listen <new_port_no.>'nginxsystemctl start nginx.service

(2) 如果该进程不重要，则通过发出命令和 start 来终止该进程nginx。要了解进程的进程 ID，请键入：ps aux|grep <process name>

kill <process id>

在终止进程之前确定您要做什么。因此我建议您更改端口号。的nginx
