Python nginx.service:无法从文件/run/nginx.PID读取PID:参数无效

我正在努力。我已经完成了图坦卡蒙，但我得到了一个502错误

My nginx服务器块配置文件：

server {
listen 80;
server_name 198..xxx.xxx.xxx mysite.org;

location = /favicon.ico { access_log off; log_not_found off; }
location /static/ {
    root /home/deploy/mysite3;
}

location / {
    include         uwsgi_params;
    uwsgi_pass      unix:/run/uwsgi/mysite3.sock;
}
}

deploy@server:/etc/nginx/sites-enabled$ sudo systemctl status nginx

nginx错误日志显示：

2017/02/06 21:10:32 [error] 7385#7385: *15 upstream prematurely closed connection while reading response header from upstream, client: 64.xxx.xxx.xxx, server: 198.xxx.xxx.xxx, request: "GET / HTTP/1.1", upstream: "uwsgi://unix:/run/uwsgi/mysite3.sock:", host: "mysite.org"

在我看来，uwsgi运行正常：

我怎样才能解决这个问题

编辑：

---

nginx.pid文件中的警告是一个已知的bug（如果不适用于其他发行版，则至少适用于Ubutnu）。详情如下：

解决方法（在ssh控制台上，作为root用户，使用下面的命令）：

然后检查是否仍然看到nginx.pid错误，以及nginx是否正在实际运行，以及是否可以连接到服务器上的端口80

我还要检查它是否确实存在以及对它的权限：

/run/uwsgi/mysite3.sock

如果nginx正在运行，而uWSGI也在运行，那么我猜这是一个配置问题

我知道您希望使用Django，因此我建议您查看实际配置，并将其与下面的配置进行比较：

我希望有帮助

我首先要做的是：mkdir/etc/systemd/system/nginx.service.dI使用

apt安装nginx

和新鲜的UBUNTU 16 LTS。。。需要纠正这个错误。如何在没有这个bug的情况下安装NGINX？关于uWSGI的段落需要更多的解释。我很确定这不是必需的，我也不使用它。这很有效。我尝试printf语句时收到一条权限被拒绝的消息，之前只有一个“sudo”。所以，我必须先进入根（“sudo su”）。然后就被处决了。剩下的是纯“sudo”，以防有人来这里使用openresty时遇到同样的问题。通过将文件添加为

/lib/systemd/system/openresty.service.d/override.conf

mkdir /etc/systemd/system/nginx.service.d
printf "[Service]\nExecStartPost=/bin/sleep 0.1\n" > /etc/systemd/system/nginx.service.d/override.conf
systemctl daemon-reload
systemctl restart nginx 

/run/uwsgi/mysite3.sock
