Step 5: Check the status of the Ubuntu default firewall by using the below command

root@linuxhelp:~# ufw status
Status: inactive

Step 6: By execute the following command to get the IP Address by using the below command

root@linuxhelp:~# hostname -I
192.168.6.133 

Step 7: Go to the Browser and search with the IP Address you get on the before step as shown in the below image

Step 8: Now setting up the Virtualhost, for that create a directory in the Apache document root directory by using the below command

root@linuxhelp:~# mkdir /var/www/linuxhelp

Step 9: Change the ownership of the created directory recursively by using the below command

root@linuxhelp:~# chown -R $USER:$USER /var/www/linuxhelp

Step 10: Change the permission of the created directory recursively by using the below command

root@linuxhelp:~# chmod -R 755 /var/www/linuxhelp

Step 11: Now create an index file in the directory by using the below command

root@linuxhelp:~# vim /var/www/linuxhelp/index.html

< html>
    <head>
        <title>Welcome to Your_domain!</title>
    </head>
    <body>
        <h1>Success!  The your_domain virtual host is working!</h1>
    </body>
</html>

Step 12: Now create a virtual host file and add the following lines by using the below command

root@linuxhelp:~# vim /etc/apache2/sites-available/linuxhelp.conf
VirtualHost *:80>
    ServerAdmin webmaster@localhost
    ServerName linuxhelp.com
    ServerAlias www.linuxhelp.com
    DocumentRoot /var/www/linuxhelp
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

Step 13: Now enable the file with the a2ensite tool by using the below command

root@linuxhelp:~# a2ensite linuxhelp.conf
Enabling site linuxhelp.
To activate the new configuration, you need to run:
  systemctl reload apache2

Step 14: Disable the default site defined in 000-default.conf by using the below command

root@linuxhelp:~# a2dissite 000-default.conf
Site 000-default disabled.
To activate the new configuration, you need to run:
  systemctl reload apache2

Step 15: Next, test for configuration errors by using the below command

root@linuxhelp:~# apache2ctl configtest
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

Step 16: Restart Apache to implement your changes by using the below command

root@linuxhelp:~# systemctl restart apache2
