a2enmod, a2dismod

a2enmod [-q|--quiet] [-m|--maintmode] [ module ]

a2dismod [-q|--quiet] [-f|--force] [-m|--maintmode] [-p|--purge] [ module ]

This manual page documents briefly the a2enmod and a2dismod commands.

a2enmod is a script that enables the specified module within the apache2 configuration. It does this by creating symlinks within /etc/apache2/mods-enabled. Likewise, a2dismod disables a module by removing those symlinks. It is not an error to enable a module which is already enabled, or to disable one which is already disabled.

Note that many modules have, in addition to a .load file, an associated .conf file. Enabling the module puts the configuration directives in the .conf file as directives into the main server context of apache2.

-q, --quiet

Don't show informative messages.

-f, --force

When disabling a module, also cascade disables all modules that depends on it.

-m, --maintmode

Enables the maintainer mode, that is the program invocation is effectuated automatically by a maintainer script. This switch should not be used by end users.

-p, --purge

When disabling a module, purge all traces of the module in the internal state data base.

a2enmod and a2dismod exit with status 0 if all modules are processed successfully, 1 if errors occur, 2 if an invalid option was used.

Enables the mod_imagemap module, and disables the mod_mime_magic module.
