RequireAll. If you use mod_authz_dbm, you must port your configuration to use Require dbm-group ... in place of Require group .... Access control In 2.2, access control based on client hostname, IP address, and will start Apache as root. Before doing this ensure that your server is properly configured for security and access restrictions. The apachectl script is designed to act like a standard SysV init script; install, Apache httpd resides at /usr/local/apache2 in the Unix filesystem or "c:/Program Files/Apache Group/Apache2" in the Windows filesystem.
