Establish Virtual Hosts in Apache
Managing multiple websites on a single server can be streamlined by leveraging virtual hosts within the Apache web server. To establish a new virtual host, you'll need to edit the configuration files located in the Apache folder. 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 additional directives required for proper performance. 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 activate the virtual host within Apache. This can be achieved through various methods depending on your operating system and Apache version. Typically, this involves symbolic linking the configuration file from the 'available' directory to the 'enabled' directory or using a command-line tool provided by Apache.
Afterward, you can access your virtual hosts through their respective URLs. For example, if you have a virtual host configured for 'example.com', you would access it by typing 'http://example.com' into your web browser.
