Configure Virtual Hosts in Apache
Managing multiple websites on a single server can be streamlined by leveraging virtual hosts within the Apache web server. To initialize a new virtual host, you'll need to modify the configuration files located in the Apache directory. Typically, this involves creating a dedicated file for each virtual host and defining its settings within that file. These settings include the server name, document root, and any further directives required for proper functionality. A common practice is to organize these configuration files in a subdirectory like 'etc/apache2/sites-available|etc/httpd/conf.d|etc/apache/sites-enabled}'.
Once configured, you'll need to enable the virtual host within Apache. This can be achieved through various methods depending on your operating system and Apache version.
