使用 django 设置 nginx

Question

我在 /home/ubuntu/test 目录中创建了一个名为“yo”的 django 项目。

这些是我的 nginx 文件：

nginx/sites-available/哟

    server {
        listen 80;
        server_name 52.89.220.11;

        location = /favicon.ico { access_log off; log_not_found off; }
        location /static/ {
            root /home/ubuntu/test/yo/static;
        }

        location / {
            include uwsgi_params;
            uwsgi_pass unix:/home/ubuntu/test/yo/yo.sock;
        }
    }

nginx/sites-enabled/yo_nginx.conf：

# mysite_nginx.conf

# the upstream component nginx needs to connect to
upstream django {
    # server unix:///home/Ubuntu/test/yo/yo.sock; # for a file socket
    server 127.0.0.1:8001; # for a web port socket (we'll use this first)
}

# configuration of the server
server {
    # the port your site will be served on
    listen      80;
    # the domain name it will serve for
    server_name 52.89.220.11; # substitute your machine's IP address or FQDN
    charset     utf-8;

    # max upload size
    client_max_body_size 75M;   # adjust to taste

    # Django media
 #   location /media  {
  #      alias /path/to/your/mysite/media;  # your Django project's media files - amend as required
   # }

    #location /static {
    #   alias /path/to/your/mysite/static; # your Django project's static files - amend as required
  }

# Finally, send all non-media requests to the Django server.
location / {
    uwsgi_pass  django;
    include     /home/ubuntu/test/yo/uwsgi_params; # the uwsgi_params file you installed
}
}

/home/ubuntu/test/yo/uwsgi_params:

uwsgi_param  QUERY_STRING       $query_string;
uwsgi_param  REQUEST_METHOD     $request_method;
uwsgi_param  CONTENT_TYPE       $content_type;
uwsgi_param  CONTENT_LENGTH     $content_length;

uwsgi_param  REQUEST_URI        $request_uri;
uwsgi_param  PATH_INFO          $document_uri;
uwsgi_param  DOCUMENT_ROOT      $document_root;
uwsgi_param  SERVER_PROTOCOL    $server_protocol;
uwsgi_param  REQUEST_SCHEME     $scheme;
uwsgi_param  HTTPS              $https if_not_empty;

uwsgi_param  REMOTE_ADDR        $remote_addr;
uwsgi_param  REMOTE_PORT        $remote_port;
uwsgi_param  SERVER_PORT        $server_port;
uwsgi_param  SERVER_NAME        $server_name;

有我的文件及其网址。当我转到端口 80 上的 domain_name 时，我得到 502 bad gateway 而不是 django 成功页面。请帮忙。

首先安装所需的应用程序。 sudo apt-get install nginx uwsgi uwsgi-plugin-python python-virtualenv 将使用的软件包版本：

Nginx
Uwsgi 
Virtualenv
Django 
Virtualenv.

我将我的项目存储在 ~/projects.现在我正在为我的项目创建 python 虚拟环境并安装 Django。

cd ~/projects/
virtualenv example.com
cd example.com
source bin/activate
pip install django
django-admin.py startproject project

Nginx 配置。 恕我直言，默认情况下，nginx 配置用于基本任务。我不会在此条目中更改此配置。配置文件存放在

/etc/nginx/sites-available. Go to this directory and create a new file.
cd /etc/nginx/sites-available

vim example.com 这是示例配置。

server {
    listen  80;
    server_name eample.com,www.example.com;
    access_log /var/log/nginx/eample.com_access.log;
    error_log /var/log/nginx/example.com_error.log;

    location / { 
        uwsgi_pass  unix:///tmp/example.com.sock;
        include     uwsgi_params;
    }

    location /media/  {
        alias /home/eshlox/projects/example.com/project/project/media/;
    }

    location  /static/ {
        alias  /home/eshlox/projects/example.com/project/project/static/;
    }
}

我们必须创建符号链接来启用它。

cd /etc/nginx/sites-enabled

ln -s ../sites-available/example.com .

Uwsgi。 与 Nginx 一样。配置文件存储在 /etc/uwsgi/apps-available 中。转到此目录并创建一个新文件。

cd /etc/uwsgi/apps-available
vim example.com.ini

编辑 example.com.ini [uwsgi]

vhost = true
plugins = python
socket = /tmp/example.com.sock
master = true
enable-threads = true
processes = 2
wsgi-file = /home/eshlox/projects/example.com/project/project/wsgi.py
virtualenv = /home/eshlox/projects/example.com
chdir = /home/eshlox/projects/example.com/project
touch-reload = /home/eshlox/projects/example.com/project/reload

启用此功能。

cd /etc/uwsgi/apps-enabled/
ln -s ../apps-available/example.com.ini .
That's all. Now, run this services.
sudo service nginx start
sudo service uwsgi start

• nginx/sites-enabled/yo_nginx.conf 中有不匹配的括号
• nginx/sites-available/yo 不被 nginx 读取 - 只有以 .conf 结尾且位于 nginx/sites-enabled/ 的文件在默认 nginx 配置中被读取。
• 由于你的命令行uwsgi --socket mysite.sock --module mysite.wsgi --chmod-socket=664 告诉uwsgi 监听unix 套接字，你的upstream django 块应该相应地修改。

这应该可以消除 502 错误。

upstream django {
    server unix:///home/ubuntu/test/yo/mysite.sock; # for a file socket, check if the path is correct
    # server 127.0.0.1:8001; # for a web port socket
}

# configuration of the server
server {
    # the port your site will be served on
    listen      80;
    # the domain name it will serve for
    server_name 52.89.220.11; # substitute your machine's IP address or FQDN
    charset     utf-8;

    # max upload size
    client_max_body_size 75M;   # adjust to taste

    # Django media
    #   location /media  {
    #      alias /path/to/your/mysite/media;  # your Django project's media files - amend as required
    # }

    # location /static {
    #     alias /path/to/your/mysite/static; # your Django project's static files - amend as required
    # }

# Finally, send all non-media requests to the Django server.
    location / {
        uwsgi_pass  django;
        include     /home/ubuntu/test/yo/uwsgi_params; # the uwsgi_params file you installed
    }
}
