suexec - Switch User For Exec
This is a customized version that can be configured with config files in
No other synopsis for usage, because this program is otherwise only used
internally by the Apache HTTP server.
is the "wrapper" support program for the suexec
behaviour for the Apache HTTP server. It is run from within the server
automatically to switch the user when an external program has to be run under
a different user. For more information about suexec in general, see the online
document `Apache suexec Support' on the HTTP server project's Web site at
This version of suexec reads a config file on every execution. Therefore it is a
bit slower than the standard suexec version from the apache2-suexec package.
If suexec is called by a user with name 'username', it will look into
/etc/apache2/suexec/username for configuration. If the file does not exist,
suexec will abort. By creating several config files, you can allow several
different apache run users to use suexec.
The first line in the file is used as the document root (/var/www in the
standard suexec) and the second line in the file is used as the suffix that is
appended to users' home directories (public_html in standard suexec).
If any of the lines is commented out (with #), suexec will refuse the
corresponding type of request. It is recommended to comment out the userdir
suffix if you don't need it.
Do not set the document root to a path that includes users' home directories
(like /home or /var) or directories where users can mount removable media.
Doing so would create local security issues. Suexec does not allow to set the
document root to the root directory / .
