Automating virtual hosts


If we create a template file for a virtual host, we can easily drop new virtual hosts using a script. First, we need a template file that is similar to the following commands:

<VirtualHost *:80>
  ServerAdmin webmaster@dummy-host.example.com
  ServerName dummy-host.example.com
  DocumentRoot /var/www/dummy-host.example.com
  ErrorLog /var/log/httpd/dummy-host.example.com-error_log
  CustomLog /var/log/httpd/dummy-host.example.com-access_log
  UseCanonicalName Off
  ServerSignature On
  <Directory "/var/www/vhosts/dummy-host.example.com">
    Options Indexes FollowSymLinks
    AllowOverride None
    Require all granted
  </Directory>
</VirtualHost>

#!/bin/bash
CONFDIR=/etc/httpd/conf.d
WEBDIR=/var/www/
mkdir -p $WEBDIR/$1
sed s/"dummy-host.example...
