Create Apache2 Virtual Host using Shell Script
The ability to create and utilize tools, makes human race dominant in world. Tools make our work easier and also saves time. One of the tools, I am going to share is bash shell script to create apache2 server virtual host.
Why Virtual Host?
Using virtual host we can run more than one web site (such as dev.drupal-cms.com, stage.drupal-cms.com and www.drupal-cms.com) on a single machine. It can be "IP-based" or “name-based”. In IP-based you can have different IP address for each web site. In name-based you can have multiple names running on each IP address.
Shell script code
Script expects 3 strings as input:
- Domain name: Name of domain you wish to give for the site. Eg: drupal-cms.local or stage.drupal-cms.com or drupal-cms
- Full path to webroot: Full path to site webroot. Eg: /var/www/html/drupal-cms
- Server admin (optional): Site server admin email id. This is optional, default value will be ‘webmaster@localhost’
Script does the following to create a virtual host for apache2:
- Creates virtual host rules files inside `/etc/apache2/sites-available/` (line number 12 to 24)
- Creates an IP address mapping in ‘/etc/hosts’ file. Mapping would be like this 127.0.0.1 $name (line number 26)
- Enables the site, a2ensite $name
- Restarts apache2 server, service apache2 reload
- Download or clone the script from https://github.com/manoj-apare/Virtual-Host-Script
- Make it executable.
- Run the command:
sudo [path-to-script]/virtual-host-script.sh [domain-name] [full-path-to-webroot] [optional-server-admin-email-id]
Note: third argument is optional.
That’s it. Now you can access the site using newly created virtual host by clicking the link printed by the script on CLI.
