我在 ubuntu 上的 ubuntu 实例上运行 nginx .

我遵循这个主题:

Nginx won't restart . . . Job for nginx.service failed because the control process exited with error code

但是,我已经在去年运行了相同的服务,但是,现在我尝试使用新的 pem 文件续订 SSL 配置 . 我的 Nginx 服务器未启动,重新启动或执行任何操作 .

$ cat /etc/nginx/sites-available/default

# Generally, you will want to move this file somewhere, and start with a clean
# file but keep this around for reference. Or just disable in sites-enabled.

    location / {
                proxy_pass http://localhost:3000;

但是,目前执行此操作:

service nginx restart

nginx.service的作业失败,因为控制进程退出并显示错误代码 . 有关详细信息,请参阅“systemctl status nginx.service”和“journalctl -xe” .

或者这个操作:

$ systemctl status nginx.service

有人知道如何解决它?
