[Go] Five Steps teach you how to use nginx + uwsgi + Django to deploy the Django Program (below)

Five steps teach you how to deploy the Django program using nginx + uwsgi + Django (below) by Django Chinese community

In the previous article "five steps teach you how to use nginx + uwsgi + Django to deploy Django programs (I)", I explained how to use uwsgi only to deploy Django programs.

Of course, uwsgi alone is not enough. nginx is an essential tool in the actual deployment environment.

In this article, I will continue to explain how to connect uwsgi with nginx to deploy Django programs using the "N-step" style. At the end, we will describe the deployment methods of the Community in a more complete manner.

Outline:

• Environment Introduction
• Configure uwsgi
• Configure nginx
• Implementation of nginx + uwsgi + Django
• Some Suggestions

Environment Introduction

1. Ubuntu 12.04.1 lts
2. Django 1.4.2
3. Nginx/1.2.6
4. Uwsgi 1.4.4

For more information about uwsgi installation, see the previous article "five steps to teach you how to deploy Django programs using nginx + uwsgi + Django (I)".

Assume that you have installed nginx.

Django ubuntu nginx

Configure uwsgi

In the previous article "five steps teach you how to use nginx + uwsgi + Django to deploy the Django Program (on)", we started uwsgi directly using the command line. In the actual deployment environment, we often use configuration files instead of command lines. My general practice is to use the command line to test whether uwsgi is successfully installed, and then use the configuration file for real deployment.

In addition, soket is used for communication between nginx and uwsgi.

In this section, we will use the uwsgi configuration file to improve the uwsgi startup mode.

502 bad gateway nginx 1.10 3 ubuntu django

Assume that your program directory is/home/work/src/sites/testdjango1/testdjango/mysite

We want nginx to use port 8077 to communicate with uwsgi. Please make sure this port is not used by other programs.

Note: Make sure that the django_wsgi.py file in the previous section "five steps teach you to use nginx + uwsgi + Django to deploy the Django Program (on)" already exists.

Create an XML file:

Djangochina_socket.xml, which is stored in the/home/work/src/sites/testdjango1/testdjango/mysite directory:

<Uwsgi> <socket>: 8077 </socket> <chdir>/home/work/src/sites/testdjango1/testdjango/mysite </chdir> <module> django_wsgi </module> <processes> 4 </ processes> <! -- Number of processes --> <daemonize> uwsgi. Log </daemonize> </uwsgi>

In the preceding configuration, we use uwsgi. log to record logs and enable four processes to process requests.

In this way, we have configured uwsgi.

Configure nginx

We assume that you will put the nginx program log under your directory/home/work/var/test/logs/. Make sure the directory exists.

Assume that the static directory of your Django is/home/work/src/sites/testdjango1/testdjango/collectedstatic /, the media directory is/home/work/src/sites/testdjango1/testdjango/public/Media/. Make sure these directories exist.

Assume that your domain name is www.you.com (you can set it to your machine IP address during debugging)

Assume that your domain name port is 80 (you can set some special ports such as 8070 during debugging)

Based on the above assumptions, we add the following configuration for CONF/nginx. conf:

server {        listen   80;        server_name www.you.com;        access_log /home/work/var/test/logs/access.log;        error_log /home/work/var/test/logs/error.log;        #charset koi8-r;        #access_log  logs/host.access.log  main;        location / {         include        uwsgi_params;         uwsgi_pass     127.0.0.1:8077;        }        #error_page  404              /404.html;        # redirect server error pages to the static page /50x.html        #        error_page   500 502 503 504  /50x.html;        location = /50x.html {            root   html;        }        location /static/ {            alias  /home/work/src/sites/testdjango1/testdjango/collectedstatic/;            index  index.html index.htm;        }        location /media/ {            alias  /home/work/src/sites/testdjango1/testdjango/public/media/;        }    }

After the preceding settings, nginx can be used to process static files (/static/AND/Media /). Nginx sends a non-static file request to socket 8077 and then sends it to uwsgi for processing.

Implementation of nginx + uwsgi + Django

After completing the preceding configuration, follow these steps:

1. Restart the nginx server to make the nginx configuration take effect.

   nginx -s  reload

   Check whether the nginx log is abnormal after restart.

2. Start uwsgi Server

   cd /home/work/src/sites/testdjango1/testdjango/mysiteuwsgi -x djangochina_socket.xml

   Check uwsgi. log for exceptions.

3. Access Service

   Based on the above assumption that your domain name is www.you.com

   Therefore, if we access www.you.com and find that the program is exactly the same as the one started by using Django separately, it means it is successful!

4. How to disable the service

   Kill the uwsgi process.

Some Suggestions

1. Number of uwsg configuration files, which can be allocated according to the actual situation. Do not open too large, otherwise the machine may consume too much memory. Generally, four processes are sufficient for a small community.

2. Generally, you can write a stop. Sh script to disable uwsgi.

At the end of this article, we would like to invite you to support the Django Chinese community. One or two of them alone will not work. We will promote it together to make the Django community more powerful! More popular!
