Set up Apache with Vhosts on Ubuntu 18.04

Make sure ubuntu is up to date

sudo apt update

Install Apache 2

sudo apt install apache2

You can set up the firewall (optional)

Check if apache's status

sudo systemctl status apache2

Should output

● apache2.service - The Apache HTTP Server
Loaded: loaded (/lib/systemd/system/apache2.service; enabled; vendor preset: enabled)
Drop-In: /lib/systemd/system/apache2.service.d

        ├─12953 /usr/sbin/apache2 -k start

Check if you can reach the default site with your browser Go to http://localhost. You should be created with "Apache2 Ubuntu default Page"

Create your virtual host named for example: tests.js

sudo vim /etc/apache2/sites-available/tests.js.conf

• Paste these directives in the file by pressing in a sequence ", +, p

 <VirtualHost *:80>
     ServerAdmin admin@example.com
     ServerName tests.js
     ServerAlias www.tests.js
     DocumentRoot "/home/g/Documents/workspace/js/tests"
     ErrorLog ${APACHE_LOG_DIR}/error.log
     CustomLog ${APACHE_LOG_DIR}/access.log combined
     <Directory "/home/g/Documents/workspace/js/tests">
         Options Indexes FollowSymlinks
         AllowOverride All
         Require all granted
     </Directory>
     #set the file that appache will serve if directory is requested
     <IfModule dir_module>
         DirectoryIndex index.php index.html
     </IfModule>
 </VirtualHost>

Enable the new vhost and disable the default one:

sudo a2ensite tests.js.conf
sudo a2dissite 000-default.conf

Test your configuration

sudo apachectl configtest
> Syntax OK

You may get the following Warning:

AH00558: apache2: Could not reliably determine the server's fully qualified domain name, using 127.0.1.1. Set the 'ServerName' directive globally to suppress this message
Syntax OK

The message is self explanatory: do sudo vim /etc/apache2/apache2.conf and type somewhere in a new line ServerName localhost

Restart apache to load your configuration:

sudo systemctl restart apache2
