Question

访问我的域名时我得到了这个：我看到我的默认，显示了http500错误django模板。

我有 gunicorn 设置：

command = '/usr/local/bin/gunicorn'
logfile = "/home/ubuntu/virtualenv/myapp/error/gunicorn.log"
loglevel = "info"
pythonpath = '/home/ubuntu/virtualenv/myapp'
bind = '127.0.0.1:8001'
workers = 3

我有 nginx 配置：

server {
        listen       80;
        server_name *.myapp.com;
        access_log /home/ubuntu/virtualenv/myapp/error/access.log;
        error_log /home/ubuntu/virtualenv/myapp/error/error.log warn;
        connection_pool_size 2048;

        fastcgi_buffer_size 4K;
        fastcgi_buffers 64 4k;

        root /home/ubuntu/virtualenv/myapp/homelaunch/;

        location /static/ {
            alias /home/ubuntu/virtualenv/myapp/homelaunch/static/;
            #alias /static/;
            #root /home/ubuntu/virtualenv/myapp/homelaunch/;
        }

        location / {
            proxy_pass http://127.0.0.1:8001;
            proxy_set_header Host $host;
            proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
            #proxy_set_header X-Forwarded-Host $server_name;
            #proxy_set_header X-Real-IP $remote_addr;
            add_header P3P 'CP="ALL DSP COR PSAa PSDa OUR NOR ONL UNI COM NAV"';
        }
    }

在这个nginx的 error_log 中我看到：

2013/10/25 00:31:49 [error] 1840#0: *1 connect() failed (111: Connection refused) while connecting to upstream, client: xx.xxx.xx.xxx, server: myapp.com, request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8001/", host: "myapp.com"

在这个nginx配置的 access_log 中，我看到：

xx.xxx.xx.xxx - - [25/Oct/2013:00:31:49 +0000] "GET / HTTP/1.1" 502 173 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:24.0) Gecko/20100101 Firefox/24.0"

我已经尝试了解问题并看到添加：

  fastcgi_buffer_size 4K;
    fastcgi_buffers 64 4k;

到nginx配置可能会有所帮助，但事实并非如此。

我对如何从这里调试这个问题感到困惑？有人可以帮忙吗？

谢谢。

Answer 1

更改您的settings.py文件，以便ALLOWED_HOSTS = ['domain']（或['*']使其正常工作）

连接到上游时，Nginx + Gunicorn + Django1.5 - connect（）失败（111：连接被拒绝）
