在AWS EC2主机上托管Django应用程序

Question

在我的AWS EC2主机上有3条路径：

1) /etc/nginx/ (包含nginx.conf文件)

2) /etc/主管/(包含supervisord.conf和project.conf文件)

3) /home/ec2-user/ project / (包含gunicorn_start.sh和项目相关文件)

nginx.conf文件(更新)：

upstream app_server {    
  server unix:/home/ec2-user/Project/run/gunicorn.sock fail_timeout=0;
}
server {
        listen       80;

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

        location /static/ {
          alias /home/ec2-user/Project/project/static/;
        }

        error_page 403 404 /404.html;
        location = /40x.html {
           root /home/ec2-user/Project/project/static/;
        }
}

gunicorn_start.sh文件：

错误日志：

2016/01/10 18:59:04 [error] 3388#0: *1 connect() to unix:/home/ec2-user/Project/run/gunicorn.sock failed (111: Connection refused) while connecting to upstream, client: xxx.xx.xx.xx, server: 52.xx.xx.xx, request: "GET / HTTP/1.1", upstream: "http://unix:/home/ec2-user/Project/run/gunicorn.sock:/", host: "52.xx.xx.xx"

代码更新/主机更改：

1)“pip安装主管”。创建了在venv/bin中可用的“supervisord”和“supervisorctl”

2) 'sudo mkdir -p /etc/主管/conf.d.d‘

3) 'sudo vim /etc/主管/con.d/project.conf‘

4)“sudo vim /etc/主管/监管人.sudo”

5) project.wsgi:application --绑定本地主机:8000

你能告诉我如何解决这个问题吗？当我点击52.xx时，我想显示file1.html而不是/usr/share/nginx/html/index.html页面。目前，我正在看到403.html页面

Answer 1

用于静态文件的。对于django项目，您需要安装应用服务器，如uwsgi或gunicorn

它将按照这样的逻辑工作：

user <-> nginx <-> app_server <-> django

这是关于nginx + gunicorn + django的指南

http://tutos.readthedocs.org/en/latest/source/ndg.html

UPD用于评论

给你一些配置，也许会有帮助。

Nginx

server {
listen 80;
server_name your_public_ip;
access_log  /var/log/nginx/your_nginx.log;

location /media  {
    alias /home/ubuntu/Project/project/media;     
    #It is path to your media, you can check this by 'pwd' command
}

location /static {
    alias /home/ubuntu/Project/project/static_root;
}
    #same
location / {
    proxy_pass http://127.0.0.1:8000;
    proxy_set_header Host $server_name;
    proxy_set_header X-Real-IP $remote_addr;
    proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
}
}

安装gunicorn并由主管自动启动

sudo apt-get install supervisor

打开文件sudo vim /etc/supervisor/conf.d/project.conf

并编写此配置

[program:project] #by this name you will call supervisor
command=/home/ubuntu/venv/bin/gunicorn --bind localhost:8000 project.wsgi:application    
enviroment=PYTHONPATH=/home/ubuntu/venv/bin    #path to virtualenv
directory=/home/ubuntu/project_folder/project  #you path to project
user=ubuntu  #your user

启动它，sudo supervisorctl start project

也是主管主管：

sudo supervisorctl reload

sudo supervisorctl status

sudo supervisorctl reread

sudo supervisorctl update
