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:

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 keystone.conf to the appropriate location for your apache server, most likely:

/etc/httpd/conf.d/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

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
