wcfg is a flexible and easy to customise script that can configure (or remove) complete LAMP-like virtual Web servers. It supports both nginx with php-fpm and apache2 with mod_php and can manage name based virtual servers, MySQL databases and privileges, FTP and SFTP users, and awstats and related static reports. It configures logrotate, and keeps everything consistent with the regulations and automatisms provided by the standard Debian packages. A new user is created for every virtual server, with the Web site root path as the home directory.
