Setting Up Nginx on Ubuntu: A Step-by-Step Guide

Introduction

Nginx is a popular, open-source web server software that offers high performance, scalability, and reliability. It is widely used in web development, content management systems, and other applications that require high-performance web serving. In this article, we will guide you through the process of setting up Nginx on Ubuntu, a popular Linux distribution.

Prerequisites

Before we begin, make sure you have the following prerequisites:

• Ubuntu 18.04 or later (64-bit)
• A basic understanding of Linux and command-line interfaces
• A text editor or IDE (Integrated Development Environment) of your choice

Step 1: Install Nginx

To install Nginx on Ubuntu, you can use the following command:

sudo apt update

sudo apt install nginx

This command will install the latest version of Nginx on your system.

Step 2: Verify Nginx Installation

To verify that Nginx has been installed correctly, open a terminal and type:

nginx -v

This command will display the version of Nginx installed on your system.

Step 3: Configure Nginx

To configure Nginx, you need to edit the Nginx configuration file. The default configuration file is located at /etc/nginx/nginx.conf. You can edit this file using a text editor or IDE.

Here’s an example of the default configuration file:

# /etc/nginx/nginx.conf



server {

    listen 80;

    server_name example.com;



    # Server name and port

    root /var/www/html;

    index index.html index.htm index.php;



    # Document root

    location / {

        try_files $uri $uri/ /index.php?_share=1;

    }



    # PHP configuration

    location ~ .php$ {

        try_files $uri =404;

        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;

        fastcgi_param SCRIPT_FILENAME $request_filename;

        include fastcgi_params;

    }



    # Error handling

    error_page 500 502 503 504 /50x.html;

    location = /50x.html {

        root /usr/share/nginx/html;

    }

}

Step 4: Create a New User and Group

To prevent Nginx from being accessed by the default user, you need to create a new user and group. Run the following commands:

sudo adduser nginx

sudo groupadd nginx

Step 5: Configure Nginx to Run as the New User and Group

To configure Nginx to run as the new user and group, you need to edit the Nginx configuration file. Add the following lines to the end of the configuration file:

user nginx;

group nginx;

Step 6: Restart Nginx

To apply the changes, you need to restart Nginx. Run the following command:

sudo service nginx restart

Step 7: Test Nginx

To test Nginx, you can use the following command:

sudo nginx -t

This command will check if Nginx is configured correctly. If everything is set up correctly, you should see no errors.

Step 8: Configure Nginx to Serve Static Files

To configure Nginx to serve static files, you need to create a new configuration file. Create a new file called nginx.conf in the /etc/nginx/sites-available/ directory:

sudo nano /etc/nginx/sites-available/example.com

Add the following lines to the end of the file:

server {

    listen 80;

    server_name example.com;



    # Server name and port

    root /var/www/html;

    index index.html index.htm index.php;



    # Document root

    location / {

        try_files $uri $uri/ /index.php?_share=1;

    }



    # PHP configuration

    location ~ .php$ {

        try_files $uri =404;

        fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;

        fastcgi_param SCRIPT_FILENAME $request_filename;

        include fastcgi_params;

    }



    # Error handling

    error_page 500 502 503 504 /50x.html;

    location = /50x.html {

        root /usr/share/nginx/html;

    }

}

Step 9: Create a Symbolic Link

To make the new configuration file available to Nginx, you need to create a symbolic link. Run the following command:

sudo ln -s /etc/nginx/sites-available/example.com /etc/nginx/sites-enabled/

Step 10: Test Nginx

To test Nginx, you can use the following command:

sudo nginx -t

This command will check if Nginx is configured correctly. If everything is set up correctly, you should see no errors.

Conclusion

Setting up Nginx on Ubuntu is a straightforward process that requires minimal configuration. By following these steps, you can install Nginx, configure it to serve static files, and test it to ensure it is working correctly. With Nginx, you can enjoy high-performance web serving and scalability, making it an ideal choice for web development and content management systems.

Additional Tips and Best Practices

• Use a secure password for the nginx user and group.
• Use a secure protocol (HTTPS) for all web traffic.
• Use a secure configuration file (e.g., nginx.conf instead of nginx.conf).
• Use a secure error handling configuration (e.g., error_page 500 502 503 504 /50x.html;).
• Use a secure PHP configuration (e.g., fastcgi_pass unix:/var/run/php/php7.4-fpm.sock;).
• Use a secure PHP file extension (e.g., .php instead of php).
