Running Keystone in HTTPD
=========================
SSL
===
To run Keystone in HTTPD, first enable SSL support. This is optional, but highly recommended.
Install mod_nss according to your distribution, then apply the following patch and restart HTTPD::
--- /etc/httpd/conf.d/nss.conf.orig 2012-03-29 12:59:06.319470425 -0400

Firewall
--------
Add the following rule to IPTables in order to ensure the SSL traffic can pass your firewall::
-A INPUT -m state --state NEW -m tcp -p tcp --dport 443 -j ACCEPT
it goes right before::
-A INPUT -j REJECT --reject-with icmp-host-prohibited
Files
-----
Copy the file httpd/wsgi-keystone.conf to the appropriate location for your apache server, most likely::
/etc/httpd/conf.d/wsgi-keystone.conf
Create the directory ``/var/www/cgi-bin/keystone/``. You can either hardlink or softlink the files ``main`` and ``admin`` to the file ``keystone.py`` in this directory. For a distribution appropriate place, it should probably be copied to::
/usr/share/openstack/keystone/httpd/keystone.py
Keystone's primary configuration file (``etc/keystone.conf``) and the PasteDeploy
configuration file (``etc/keystone-paste.ini``) must be readable to HTTPD in
one of the default locations described in :doc:`configuration`.
SELinux
-------
If you are running with SELinux enabled (and you should be) make sure that the file has the appropriate SELinux context to access the linked file. If you have the file in /var/www/cgi-bin, you can do this by running::
sudo restorecon /var/www/cgi-bin
Putting it somewhere else requires you set up your SELinux policy accordingly.
Keystone Configuration
----------------------
Make sure you use the ``SQL`` driver for ``tokens``, otherwise the tokens will not be shared between the processes of the Apache HTTPD server. To do that, in ``/etc/keystone/keystone.conf`` make sure you have set::
[token]
driver = keystone.token.backends.sql.Token
