open()“/run/nginx.pid”失败（13：权限被拒绝）

Question

目前，我已经设置了一个 nextcloud 服务器nginx并使用 启用了它sudo systemctl enable nginx.service。当我重新启动时，我收到一条错误消息，抱怨代理服务器，如果我查看一下sudo systemctl status nginx.service，我会收到以下消息：

nginx.service - A high performance web server and a reverse proxy server
     Loaded: loaded (/etc/systemd/system/nginx.service; enabled; vendor preset: disabled)
     Active: failed (Result: exit-code) since Sat 2020-11-14 12:20:55 CET; 16min ago

Nov 14 12:20:55 TORNAX-ARCH systemd[1]: Failed to start 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

当我寻找有关此open() "/run/nginx.pid" failed (13: Permission denied)错误的解决方案时，我只获得 docker + nginx 的解决方案，如下所示：

• /sf/ask/4507526621/
• https://dockerquestions.com/2020/10/16/nginx-emerg-open-run-nginx-pid-failed-13-permission-denied/
• https://github.com/Wonderfall/dockerfiles/issues/40

手动重新启动服务后它可以工作，但当我运行时sudo systemctl restart nginx.service我仍然收到.open() "/run/nginx.pid" failed (13: Permission denied)nginx -t

我做错了什么或者我可以做什么来解决这个问题？

Answer 1

sudo nginx -t

在我看来，这个评论应该是一个答案。

Run nginx -t as root. This is a red herring. \xe2\x80\x93 Michael Hampton Nov 15 at 0:27

Answer 2

这可能是一个错误。“此行为是一个已知错误，由 nginx 和 systemd 之间的竞争条件引起。Systemd 期望在 nginx 有时间创建 PID 文件之前填充该文件。” https://www.cloudinsidr.com/content/heres-fix-nginx-error-failed-read-pid-file-linux/

无论如何，如果网站再次关闭，请按照以下步骤进行修复：

分步指南

1. 在 /etc/systemd/system/ 中创建一个名为 nginx.service.d 的目录：

mkdir -p /etc/systemd/system/nginx.service.d

2. 将以下内容添加到/etc/systemd/system/nginx.service.d/override.conf：

[Service]
ExecStartPost=/bin/sleep 0.1

3. 重新加载 systemd 管理器配置：

[Service]
ExecStartPost=/bin/sleep 0.1

4. 重新启动 NGINX：

systemctl daemon-reload

复制+粘贴上面的命令

systemctl restart nginx
