Installing a Web Server on Ubuntu: A Step-by-Step Guide
Step 1: Updating Your Ubuntu Server
Before you start installing the web server, it’s important to ensure that your Ubuntu server is up-to-date. This can be done by running the following commands:
Command |
Description |
|---|---|
sudo apt update |
Updates the package lists for upgrades and installs. |
sudo apt upgrade |

Step 2: Installing the Web Server
The next step is to install the actual web server. In this guide, we will be using Apache2, one of the most popular web servers out there. You can install it by running the following command:
sudo apt install apache2
This command will install Apache2 along with its dependencies, which include PHP, MySQL, and other useful packages.
Step 3: Configuring the Firewall
After installing the web server, it’s important to configure the firewall to allow traffic to pass through. You can do this by running the following commands:
Command |
Description |
|---|---|
sudo ufw allow ‘Apache Full’ |
Allows HTTP and HTTPS traffic to pass through the firewall for Apache. |
sudo ufw enable |

Step 4: Testing the Web Server
Once you’ve installed the web server and configured the firewall, it’s time to test if everything is working correctly. You can do this by opening a web browser and typing in your server’s IP address or domain name. You should see the default Apache2 web page.
Step 5: Creating Virtual Hosts
If you want to host multiple websites on your server, you’ll need to create virtual hosts. Virtual hosts allow you to run multiple websites on a single server, with separate configuration files and domains. You can create a virtual host by following these steps:
Command |
Description |
|---|---|
sudo mkdir /var/www/example.com/html |
Creates a new directory for your website. |
sudo chown -R $USER:$USER /var/www/example.com/html |
Changes the owner of the directory to the current user. |
sudo chmod -R 755 /var/www/example.com |
Changes the directory’s permissions so that it’s readable and executable by everyone. |
After creating the directory, you need to create a new virtual host configuration file in the /etc/apache2/sites-available/ directory. You can use the following command to create a new file:
sudo nano /etc/apache2/sites-available/example.com.conf
After creating the file, add the following lines in it:
ServerName example.comServerAlias www.example.comDocumentRoot /var/www/example.com/html
Then, save and close the file. Finally, activate the new virtual host by running the following command:
sudo a2ensite example.com.conf
Restart Apache for the changes to take effect:
sudo systemctl restart apache2
