Fixed #7616 -- Added advice on unix socket permissions and umasks to fastcgi...

    ./manage.py runfcgi method=prefork socket=/home/user/mysite.sock pidfile=django.pid

.. admonition:: Socket security

    Django's default umask requires that the webserver and the Django fastcgi

    process be run with the same group **and** user. For increased security,

    you can run them under the same group but as different users. If you do

    this, you will need to set the umask to 0002 using the ``umask`` argument

    to ``runfcgi``.

Run without daemonizing (backgrounding) the process (good for debugging)::

    ./manage.py runfcgi daemonize=false socket=/tmp/mysite.sock maxrequests=1
