How to Install Nginx Debian 9

What is Nginx?

Nginx (pronounced “engine-x”) is an open source web server and reverse proxy software. It is known for its light weight and high performance. Since its launch in 2004, Nginx has become one of the most popular web servers powered by millions of websites worldwide. It can be used to serve static files, host applications, and even as a mail proxy. Nginx is available for most Linux distributions and is the default web server for the Debian 9 operating system.

Prerequisites for Nginx Install on Debian Server

Before attempting to install Nginx, you should make sure your server has the following prerequisites in place:

  • A Debian 9 server running as a non-root user with sudo privileges.
  • A domain name pointed towards your server’s public IP address.
  • A a running firewall and an optimized UFW firewall setup.

Step 1: Update System Packages

It is always a good idea to make sure that all your system packages are up to date before you begin the installation of any software.

To make sure you are using the latest packages, run the following command in your terminal window. This will download and install any updates available:

sudo apt-get update

Step 2: Install Nginx

Now that the system is up to date, we can install Nginx. To do this, run the following command:

sudo apt-get install nginx

Once the installation is complete, you should be able to access the server properties by typing in the following command:

sudo nginx -v

You should see an output that looks something like this:

nginx version: nginx/1.14.0

This version number tells you that Nginx version 1.14.0 is currently running on your server.

Step 3: Start and Stop Nginx Server

To start the Nginx server, run the following command:

sudo systemctl start nginx

To stop the server, run the command:

sudo systemctl stop nginx

If the server is already running, you can restart it with this command:

sudo systemctl restart nginx

Step 4: Configure Nginx Server Blocks

Once the Nginx server is up and running, you’ll need to configure it to use server blocks in order to host multiple websites.

Server blocks are a way to configure the Nginx web server to respond to requests for different hostnames. This allows you to run multiple websites on a single server. You can configure each website independently, with its own documents root and access permissions.

In order to create a server block for your domain, you’ll need to create a new configuration file in the sites-available directory. This can be done with the following command, replacing example.com with your domain name:

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

Inside this file, you can configure your server block. This can contain things such as the document root directory, additional server directives, and secure connection settings.

Once you have finished configuring your server block, you’ll need to enable it by creating a symbolic link from the sites-available directory to the sites-enabled directory. This can be done with the following command, again replacing example.com with your domain name:

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

Step 5: Test Nginx Configuration

Once you have enabled your server block, you should test your Nginx configuration for any potential errors. To do this, run the following command:

sudo nginx -t

If the configuration is valid, you should see an output that looks something like this:

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

Once you have ensured your configuration is valid, you can restart the server so that the changes you have made take effect:

sudo systemctl restart nginx
