Deploy Django App With Apache Server On Ubuntu¶
In this article we will learn about how to deploy django app on apache server. Apache server is a free and open-source HTTP server that is free to use. It is a cross platform web-server, It support's most of the operating systems like windows, linux, Mac, etc. Apache server is not intended to use to create any website. The main purpose of apache is to redirect HTTP requests to other applications like WSGI then these will process the request. If it is a static content then we can serve the resources directly with apache server.
Advantages of Apache Server
- It is free and opensource
- Easy process to install and configure apache
- Changes will be reflected immediately
- Wide range of community support from forums like stackoverflow.com
- Support for hosting multiple websites on single server
How to install apache server on ubuntu ?¶
Run the below command to install the apache2 server and mod_wsgi. mod_wsgi supports the apache to run python application.
sudo apt-get install apache2 libapache2-mod-wsgi
<VirtualHost *:80> ServerName example.com ServerAdmin [email protected] DocumentRoot /path/to/project Alias /static/ /path/to/static/ Alias /media/ /path/to/media/ WSGIScriptAlias / /path/to/project/project/wsgi.py WSGIDaemonProcess example.com python-path=/path/to/project \ python-home=/path/to/env3 processes=5 threads=2 WSGIProcessGroup example.com <Directory /path/to/project/> Options -Indexes Order deny,allow Allow from all Require all granted </Directory> <Directory /path/to/media> Options -Indexes Order deny,allow # Allow from all Require all granted </Directory> LogLevel info # PROJECT_NAME is used to seperate the log files of this application ErrorLog /path/to/logs/error.log CustomLog /path/to/logs/access.log combined </VirtualHost>
After installing it, follow the below procedure
- Go to the directory "/etc/apache2/sites-available/" and create a configuration file named "my_apache_website.conf" and copy the above configuration.
- Update the above configuration file by replacing the paths "static", "media", "project", "virtualenv", "document root", "error_log" and "access log" with actual paths and also update "server name", "server admin"
- Test the configuration file with the command "apachectl configtest"
- Now, restart the apache server with the command "sudo service apache2 restart"
- Check the status of the apache server with the command "sudo service apache2 status"
- We have successfully configured the django application with apache. Now, we can access the django web application(example.com) in the browser.
