connect（）失败（111：连接被拒绝），同时连接到上游，客户端

Question

我想部署一个Django实例到ec2。我正在使用nginx和gunicorn的组合来实现这一点。我得到了nginx isntance和gunicorn正确启动，我能够让我的实例运行。但是，当我试图将影像上传到我的应用程序的数据库我遇到这个错误在我gunicorn error.log中：

连接失败的-111连接，拒绝，同时，连接到上游

从前端到数据库的所有api调用都会在控制台中返回一个500内部服务器。 我的nginx.conf看起来像

default_type  application/octet-stream; 

# Load modular configuration files from the /etc/nginx/conf.d directory. 
# See http://nginx.org/en/docs/ngx_core_module.html#include 
# for more information. 
include /etc/nginx/conf.d/*.conf; 
include /etc/nginx/sites-enabled/*; 
include /etc/nginx/sites-available/*; 
index index.html index.htm; 

server { 
    listen  127.0.0.1:80; 
    listen  [::]:80 default_server; 
    server_name 127.0.0.1; 
    root   /usr/share/nginx/html; 

    # Load configuration files for the default server block. 
    include /etc/nginx/default.d/*.conf; 

    location/{ 
    } 

    # redir 

而且我启用的站点 - /默认文件

upstream app_server_djangoapp { 
server 127.0.0.1:8000 fail_timeout=0; 

}

服务器{ ＃EC2实例安全组必须配置为接受HTTP连接通过80端口 听80; server_name myec2isntance.com;

access_log /var/log/nginx/guni-access.log; 
error_log /var/log/nginx/guni-error.log info; 

keepalive_timeout 5; 

# path for static files 
location /static { 
    alias xxxxxx; 
} 
location /media { 
    alias xxxxxx; 
} 
location/{ 
location/{ 
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
    proxy_set_header Host $http_host; 
    proxy_redirect off; 

    if (!-f $request_filename) { 
     proxy_pass http://app_server_djangoapp; 
     break; 
    } 
} 

}

我想大多数人津津乐道的事情 - 将右permissisons的文件夹。改变本地主机为127.0.0.1等我对这个主题相对较新，所以任何帮助将不胜感激！

谢谢

我会建议默认改成这样：

upstream app_server_djangoapp { 
server 127.0.0.1:8000 max_fails=3 fail_timeout=50; 
keepalive 512; 
} 

- 删除

keepalive_timeout 5; 

- 为什么ü有两个位置/块？

location/{ 
    location/{ 
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; 
    proxy_set_header Host $http_host; 
    proxy_redirect off; 

    if (!-f $request_filename) { 
     proxy_pass http://app_server_djangoapp; 
     break; 
    } 
}
