目前，我已经设置了一个 nextcloud 服务器，nginx并使用sudo systemctl enable nginx.service. 当我重新启动时，我收到一条抱怨代理服务器的错误消息，如果我查看一下sudo systemctl status nginx.service，我会收到以下信息：
nginx.service - A high performance web server and a reverse proxy server

如果我跑步nginx -t，我会得到这个：
2020/11/14 12:37:40 [warn] 68391#68391: could not build optimal types_hash, you should increase either types_hash_max_size: 1024 or types_hash_bucket_size: 64; ignoring types_hash_bucket_size
nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
2020/11/14 12:37:40 [emerg] 68391#68391: open() "/run/nginx.pid" failed (13: Permission denied)
nginx: configuration file /etc/nginx/nginx.conf test failed
当我正在寻找有关此open() "/run/nginx.pid" failed (13: Permission denied)错误的解决方案时，我只能获得 docker + nginx 的解决方案，例如这些帖子：
- https://stackoverflow.com/questions/57427162/nginx-emerg-open-var-run-nginx-pid-failed-13-permission-denied
- https://stackoverflow.com/questions/64393237/nginx-emerg-open-run-nginx-pid-failed-13-permission-denied
- https://dockerquestions.com/2020/10/16/nginx-emerg-open-run-nginx-pid-failed-13-permission-denied/
- https://github.com/Wonderfall/dockerfiles/issues/40
它在手动重新启动服务后工作，sudo systemctl restart nginx.service但我仍然open() "/run/nginx.pid" failed (13: Permission denied)在运行时得到nginx -t。
我做错了什么或者我能做些什么来解决这个问题？
