Hi,

I couldn't able to configure keystone on Killo, since I am getting socket error. Please find the below configuration and error details and help me to fix this issue..

Have you considered that from Kilo release the keystone service is disabled ?

In Kilo and Liberty releases, the keystone project deprecates eventlet in favor of a separate web server with WSGI extensions. This guide uses the Apache HTTP server with mod_wsgi to serve Identity service requests on port 5000 and 35357. By default, the keystone service still listens on ports 5000 and 35357. Therefore, this guide disables the keystone service. The keystone project plans to remove eventlet support in Mitaka. Source

Attempt source credentials && run again :-

su -s /bin/sh -c "keystone-manage db_sync" keystone
service keystone restart

Looks like first instance is already running, you may also try identify process bound to port && kill it and try restart.

kill -9 `fuser -n tcp 5000`
kill -9 `fuser -n tcp 35357`

On working RDO Kilo Controller :-

I have the same problem about you . I find the port 5000 and 35357 is used by apache netstat -tunlp | grep 35357 tcp6 0 0 :::35357 :::* LISTEN 6784/httpd

apache use port 35357 because: the docs tell us edit /etc/httpd/conf.d/wsgi-keystone.conf Listen 5000 Listen 35357

<virtualhost *:5000=""> WSGIDaemonProcess keystone-public processes=5 threads=1 user=keystone display-name=%{GROUP} WSGIProcessGroup keystone-public WSGIScriptAlias / /var/www/cgi-bin/keystone/main WSGIApplicationGroup %{GLOBAL} WSGIPassAuthorization On LogLevel info ErrorLogFormat "%{cu}t %M" ErrorLog /var/log/httpd/keystone-error.log CustomLog /var/log/httpd/keystone-access.log combined </virtualhost>

<virtualhost *:35357=""> WSGIDaemonProcess keystone-admin processes=5 threads=1 user=keystone display-name=%{GROUP} WSGIProcessGroup keystone-admin WSGIScriptAlias / /var/www/cgi-bin/keystone/admin WSGIApplicationGroup %{GLOBAL} WSGIPassAuthorization On LogLevel info ErrorLogFormat "%{cu}t %M" ErrorLog /var/log/httpd/keystone-error.log CustomLog /var/log/httpd/keystone-access.log combined </virtualhost>

so the openstack-keystone could not start. I do not know how to solve this problem. I just stop apache service then start openstack-keystone,it is ok. But apache is top.

Best regards!

I've just completed RDO Kilo AIO install on real box and see :-

== Keystone service ==
openstack-keystone:                     inactive  (disabled on boot)

Generated answer-file provide an options ( both of them would work on RDO Kilo)

I encountered a similar issue with a recent RDO Packstack Juno deployment. After the deployment, Keystone wouldn't start because port 35357 was being used by HTTP.

It turned out Puppet had reserved those ports in /etc/httpd/conf/ports.conf for httpd which was causing keystone to fail on start up because it couldn't bind to port 35357.

By commenting out ports 5000 and 35357 in /etc/httpd/conf/ports.conf and restarting httpd and keystone services, it all seemed to work again. So far the deployment doesn't seem to be having any authentication or dashboard issues with those ports commented out of the ports.conf file.

Hopefully that helps ...

I didn't use packstack installation process.. So shall I change th below file for port 5000 & 35357

/etc/httpd/conf.d/wsgi-keystone.conf

Can you run the commands below to see what the ports are bound too?

lsof -i -n -P | grep keystone; lsof -i -n -P | grep httpd
