Hi, I'm following the installation guide to deploy in a centos environment (link: ).

I added the the variables

export OS_TOKEN="2aea3e1a346d56c3bcbb"
export OS_URL=""

and then run the command:

openstack service create \
  --name keystone --description "OpenStack Identity" identity

with the following result message:

"An unexpected error prevented the server from fulfilling your request. (HTTP 500) (Request-ID: req-6b58d146-ac1f-40e3-8e05-ae35e81425bb)"

The Request-ID changes every time I try the command. I checked the token in the /etc/keystone/keystone.conf that is the same in the variable OS_TOKEN. Also, I removed the # in the keystone.conf file (Another person had that problem in a similar question).

In another post someone suggested to run the command in --debug. Here is my output:

[root@liberty21 ~]# openstack --debug service create --name keystone --description "OpenStack Identity" identity --enable

Have a look at the keystone log file under /var/log/keystone. First focus on lines labeled with "error". You may also benefit from switching on debugging in the config file.

Also, when posting ouput, format it using the "101010" button.

I have encountered the same issue on Juno. To troubleshoot this issue, added a line to /etc/keystone/keystone.conf as below and that worked for me.!

vi /etc/keystone/keystone.conf

connection = mysql://keystone:pass@aioX/keystone

connection = mysql://keystone:pass@localhost/keystone # new line added to suppress HTTP 500 error

After that run these commands again to reflect keystone.conf changes made,

Populate the database tables for the Identity Service:

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

Restart the Identity Service: sudo systemctl enable openstack-keystone.service sudo systemctl start openstack-keystone.service


export OS_SERVICE_ENDPOINT=http://aioX:35357/v2.0

Thanks a lot. On a quick note, the lines are under [database], in case someone need to find it quickly, they can use /\<database\>
