Upgrade Nginx Ubuntu 18.04
Getting Started with Nginx Ubuntu 18.04 Installation
Nginx is a high performance web server and reverse proxy. It is written in C and has ways to optimize the performance. It is free, open-source and secure. Nginx is used by millions of websites and applications to power their production environments. It is also highly resilient and easy to use.
For users running Ubuntu 18.04, installing Nginx is extremely simple. Before starting, make sure that you are logged in as a user with sudo privileges. You can check this by running the sudo -l command. If you don’t have sudo privileges, contact your system administrator.
First, update the package index by running the following command:
sudo apt update
Once the package index has been updated, the Nginx package can be installed from the default Ubuntu repositories with the following command:
sudo apt install nginx
When the installation is complete, the Nginx service will start automatically. You can confirm that Nginx is running by typing:
sudo systemctl status nginx
Configuring Nginx Ubuntu 18.04
Once the Nginx installation is complete, the next step is to configure it. The default configuration files are stored in the /etc/nginx/ directory. The main configuration file is nginx.conf. This file contains directives that configure the behavior of Nginx. It also includes directives that define how to handle incoming requests.
To modify the main configuration file, use the following command:
sudo nano /etc/nginx/nginx.conf
Make any changes to the file, then save your changes and close the text editor. To apply the changes, you need to restart the Nginx service. This can be done with the following command:
sudo systemctl restart nginx
Creating an Nginx Virtual Host
By default, Nginx will serve the default site, which is located in the /var/www/html/ directory. To set up a virtual host, create a new server block. A server block is a configuration file that routes requests to a specific directory on your server.
To create a new server block, use the following command:
sudo nano /etc/nginx/sites-available/example.com.conf
This will open a new file in the text editor. You can copy the following server block configuration:
server_name example.com www.example.com;
index index.html index.css index.js index.php;
The “server_name” directive is used to configure the name of the server. Substitute the example.com and www.example.com with the domain name you wish to use.
When you have configured the server block, save your changes and close the text editor. To enable the new server block, create a symbolic link from the sites-available directory to the sites-enabled directory with the following command:
sudo ln -s /etc/nginx/sites-available/example.com.conf /etc/nginx/sites-enabled/
Testing Nginx Configuration
To test your Nginx configuration, use the following command:
sudo nginx -t
This command will check if your Nginx configuration file contains any syntax errors and will display the results. If the test passes, restart Nginx to apply the changes:
sudo systemctl restart nginx
Upgrading Nginx on Ubuntu 18.04
When a new version of Nginx is released, you may be able to upgrade to the latest version by performing a few commands. To upgrade Nginx, first check for any available updates on the Ubuntu repositories with the command:

Once the package index is updated, check for any available Nginx updates with:
sudo apt list nginx
If there is an upgrade available, you can install it with the following command:
sudo apt upgrade nginx
To uninstall Nginx, use the following command:
sudo apt remove nginx
Once the uninstallation is complete, you can remove all of its configuration files with the following command:
sudo apt purge nginx
