Deploy Django + uWSGI + Nginx with Docker

With Docker deploy Django + uWSGI + Nginx

• The steps outlined below:
• Creating Centos container
• Install Python and pip
• Install MySQL
• The Django connect to MySQL
• Run uWSGI server
• Running Nginx server

     

  Creating Centos container

  Installation docker software

  yum install docker
  									

• Create a centos container

  docker run -d --name
  									deploy1 --network host centos tail -f /dev/null 

• -d : let it run in the background.
• Deploy1 -name : set name.
• Host -network : it joins the network host computer, can be connected to external networks.
• CentOS : To run the mirror. docker will automatically pull from the official mirror latest version.
• -f tail / dev / null : let the container has to execute a command, so there is no task automatically exit.

  Enter centos container.

  docker exec -it deploy1 bash
  									

     

•  The Django project copy the source code from the host into the centos vessel

  docker cp /root/django deploy1: /var/www/web_project 

  Install Python and pip

  yum install epel-release # 添加epel软件库
  								

   

  yum install python34 # 安装指定版本的python
  								

  Then use pip install Django project requires Python third party libraries.

  If there is a project directory requirements.txt , you can use pip3.4 install -r requirements.txt

     

  Install MySQL

  Yum install mariadb
  									

  Execution Mysql_secure_installtion initialize, set a password for 123456

     

  The Django connect to MySQL

  DATABASES = {
  

   

      'default': {
  

   

          'ENGINE': 'django.db.backends.mysql',   # 数据库引擎，不用改
  							

   

          'NAME': 'blog',          # database名，需要在mysql中已存在
  								

   

          'USER': 'root',
  

   

          'PASSWORD': '******',
  

   

          'HOST': '127.0.0.1',
  

   

          'PORT': '3306',
  

   

      }
  

   

  }
  

   

  Run uWSGI server

• Dependent libraries: yum install Build-Essential Python-devel
• Installation uWSGI : PIP install uwsgi
• Into the Django project directory, execute mkdir uwsgi , create a uwsgi folder. Then execute vi uwsgi / uwsgi.ini , under which created a uwsgi.ini , as a configuration file. Which reads as follows:

  [uwsgi]
  							

   

  chdir           = /var/www/web_project
  

   

  socket= 127.0.0.1:3301 

   

  http = 0.0.0.0:8001 

   

  module          = web_project.wsgi
  

   

  #home            = /var/www/vitual/
  							

   

  master          = true
  								

   

  processes       = 5
  								

   

  vacuum          = true
  								

   

  daemonize=/var/log/uwsgi.log
  							

  Using a configuration file to start uWSGI server (default run in the background): uwsgi --ini uwsgi / uwsgi.ini

     

  Running Nginx server

  Install Nginx : yum install nginx

  Modify Nginx configuration file /etc/nginx/site-enable/mysite_nginx.conf

  upstream django {
  

   

      server
  									127.0.0.1:3301; # for a web port socket (we'll use this first) 

   

  }
  

   

   

   

  server {
  

   

      # the port your site will be served on
  								

   

      listen      8081; 

   

      # the domain name it will serve for
  								

   

      server_name _; # 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 /var/www/web_project/media/;  # your oDjango project's media files - amend as required 

   

  }
  

   

       location /static {
  

   

          alias  /var/www/web_project/allstatic/; # your Django project's static files - amend as required 

   

  }
  

       location /admin {
  

   

          uwsgi_pass  django;
  

   

          include     uwsgi_params; # the uwsgi_params file you installed 

   

   

   

   

   

  }
  

      location /api {
  

   

          uwsgi_pass  django;
  

   

          include     uwsgi_params; # the uwsgi_params file you installed 

   

      }
  

   

   

   location /ckeditor/upload/ {
  

   

             proxy_method POST;
  

   

             proxy_pass   http://127.0.0.1:8001$request_uri; 

   

      }
  

   

      location / {
  

   

          root  /var/www/html/dist;
  

   

          index  index.html;
  

   

          #try_files $uri $uri/ /index.html;
  								

   

          }
  

  }
  

   

  First start uWSGI server, then nginx start nginx server (default runs as a daemon)

     

     

• Persistent data

  docker run -d -p 80:8081 -p 10000:8001  --restart=always --privileged=true -v /usr/docker_dat/mysql/data:/var/lib/mysql --name newblog5 -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root  webblog_4 

     

  Mapping the local directory to the interior of the container / var / lib / msyql

• The first database will be reported no authority to modify mysql database permissions

  chown -R mysql /var/lib/mysql
