Instal Python Web Centos 7 Django Nginx

Introduction to Installing Python Web Centos 7 Django Nginx

In this article, we will be covering an installation of Python web framework Django, Nginx web server, and CentOS 7, as well as how to configure them all together. We will be starting from scratch and looking into how we can create a functioning web server in no time.

Python is a high-level, versatile language that has been used by many of the world’s largest companies, such as Google, Dropbox, Netflix and more.

It is widely used in web development, software development, and general scripting. Many use Python to build websites or automate tasks. Django is an open-source web framework that allows for fast and secure development of websites, as well as creation of data-driven web applications. Django supports a wide variety of databases, and it is well suited for large projects.

Nginx is an open-source web server that is known for its performance, low resource usage, and reliable configuration. CentOS is a Linux distribution designed for enterprise-level applications, and is known for its stability and reliability.

Preparing Your Server

Before we can install the components mentioned earlier, we will need to prepare the server. We will need an existing CentOS 7 installation running, which can be done using a virtual machine or on a physical server.

Once we have a running system, we will need to ensure that all available updates for the system have been installed. This can be done with the following command from a terminal:

sudo yum -y update

This command will update all packages on your system, ensuring that the system is up to date.

Installing Nginx

Now that we have a running system, we will need to install the Nginx web server. This can be done from the CentOS 7 software repositories, and is very easy to do using the yum package manager. To install Nginx, use the command:

sudo yum install nginx

This will download and install the necessary packages for the Nginx web server. Once the installation is complete, we will need to start and enable the Nginx web server. This can be done with the commands:

sudo systemctl start nginx

sudo systemctl enable nginx

The first command will start the Nginx service, and the second command will enable it to start on boot.

Installing Python

Now that we have the Nginx web server installed and running, we will need to install Python. This can be done using the yum package manager. To install Python, run the following command from the terminal:

sudo yum install python3

This command will download and install the necessary packages for Python, and is all that is needed to install the Python language.

Installing Django Framework

Now that we have Python installed, we will need to install Django, which is the Python web framework we will be using. This can be done using the pip package manager. To install Django, run the command:

sudo pip install Django

This command will download and install the necessary packages for the Django framework. Once the installation is complete, we can start using the framework for web development.

Configuring Nginx for Django

Now that we have Django installed, we will need to configure Nginx to work with the framework. To do this, we will need to edit the Nginx configuration files. These configuration files are located in the /etc/nginx/ directory. We will need to edit the nginx.conf file, as well as any other configuration files that may be required for our setup.

First, we will need to edit the nginx.conf file. This file contains the main configuration for Nginx, and is where we will need to add our Django configuration. Here is an example of what our configuration could look like:

server {

    listen 80;

    server_name www.example.com;

    charset utf-8;

    client_max_body_size 75M;

    access_log off;

 

    location /static {

        alias /var/www/static;

    }

    

    location / {

        proxy_pass http://localhost:8000;

        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;

        proxy_set_header Host $host;

        proxy_redirect off;

    }

  }

This example configuration will forward all requests to the localhost port 8000, which is where our Django application will be running. Once we have added our configuration, we will need to save the file and restart the Nginx web server.

Configuring Django

Now that we have Nginx configured, we will need to configure Django to run with our configuration. The first step is to create a Django project. This can be done using the django-admin package that was installed earlier. To create a project, run the following command from the terminal:

django-admin startproject example_project

This command will create a new Django project in the current directory. We will also need to edit the settings.py file in the project folder. This file contains all of the configuration options for the Django project. We will need to change the settings for the ALLOWED_HOSTS option, as well as the STATIC_ROOT option. The ALLOWED_HOSTS option should contain the IP address of the server that is running the application. The STATIC_ROOT option should contain the full path to the specified static directory.

Once all of the configuration options have been set, we will need to collect all of the static files for the project. This can be done using the manage.py script that was created when we created the project. To do this, run the following command from the terminal:

python manage.py collectstatic

This command will collect all of the static files and put them into the specified static directory. Once this is complete, we will need to start the Django application. This can be done using the following command:

python manage.py runserver 0.0.0.0:8000

This command will start the Django application on the specified port, and will allow it to be accessed by Nginx.

Conclusion

In this article, we have covered how to install and configure Python web framework Django, Nginx web server, and CentOS 7. We have also gone over how to configure Nginx and Django to work together. Once these steps have been completed, we will have a functioning web server running Django.
