Checked the DB tables and found that is was not created so i droppped the DB and followed below commmands and it worked it worked immediately

The Identity Service uses a database to store information. Specify the location of the database in the configuration file. In this guide, we use a MySQL database on the controller node with the username keystone. Replace KEYSTONE_DBPASS with a suitable password for the database user.

# openstack-config --set /etc/keystone/keystone.conf \ database connection mysql://keystone:KEYSTONE_DBPASS@[you controller name]/keystone

Use the password that you set previously to log in as root. Create a keystone database user:

$ mysql -u root -p mysql> CREATE DATABASE keystone; mysql> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'localhost' \ IDENTIFIED BY 'KEYSTONE_DBPASS'; mysql> GRANT ALL PRIVILEGES ON keystone.* TO 'keystone'@'%' \ IDENTIFIED BY 'KEYSTONE_DBPASS'; mysql> exit

Create the database tables for the Identity Service:

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

After the above command login to mysql and check if tables are created and after that the user create command works fine

Hi,

I navigated between many forums to figure out the answer and I found out a good solution, which is working for me:

Instead of typing the command: # su -s /bin/sh -c "keystone-manage db_sync" keystone, you must type only: /bin/sh -c "keystone-manage db_sync" keystone

The issue came that: if you have already loggin as a root so you haven't needed anymore to use the "su -s" command.

After that, you can execute the command: openstack service create --name keystone ==description "OpenStack Identity" identity, which will work perfectly fine.

Hi,

I recently encountered the same issue, later I found a spelling mistake under /etc/keystone/keystone.conf:

Connection URL before spelling correction: [database] connection = mysql+pymysql://keystone:keystone_dbadmin@controller/keyston

Connection URL post spelling correction: [database] connection = mysql+pymysql://keystone:keystone_dbadmin@controller/keystone

Post spelling correction performed db_sync and problem has resolved

Regards, Farooq

When I did encountered this, my issues were the following:

  • The variable that "ServerName" was set to in /etc/httpd/conf/httpd.conf was not the name of my server
  • The variable "ServerName" in /etc/httpd/conf/httpd.conf was mistakently typed as "Servername" and not "ServerName" (Notice the n was lowercase when it should have been capitalized)
  • The Bootstrap identity service was not pointing to my servername and was instead pointing to the default "controller" servername given in the instructions. Its not ideal to simply always copy and paste.
  • The OS_AUTH_URL environment variable was pointing to the default controller servername given in the instructions.

My problem was simply a copy paste, copy paste, copy paste issue. :-( .Once I corrected this everything worked fine.

Keep in mind that once you update this, you simply need to run commands:

systemctl stop httpd.service systemctl start httpd.service

This way your changes will take affect.

Hey, Check if the keystone service is up by

[root@my-controller1 root]# netstat -anutp|grep 35357
tcp        0      0 0.0.0.0:35357               0.0.0.0:*                   LISTEN      27874/python
[root@my-controller1 root]#

also it will be great to check the keystone by

telnet 0 35357

you should be able to see something like this

Trying 0.0.0.0...
Connected to 0.
Escape character is '^]'.
get
<head>
<title>Error response</title>
</head>
<body>
<h1>Error response</h1>
<p>Error code 400.
<p>Message: Bad request syntax ('get').
<p>Error code explanation: 400 = Bad request syntax or unsupported method.
</body>
Connection closed by foreign host.

I'm also getting the expected output (per fgorbat). The service is also running. But still getting the 500 error. Has anybody managed to resolve this ?

I had single quotes around mariadb password in keystone.conf mysql connection uri

Changed it from

[database] ... connection = mysql://keystone:'KEYSTONE_DBPASS'@controller/keystone

To..

[database] ... connection = mysql://keystone:KEYSTONE_DBPASS@controller/keystone

and viola!

I was also having same error while creating tenant, following these http://docs.openstack.org/juno/install-guide/install/apt/content/keystone-install.html (steps). I was logged in as root, and executing "su -s /bin/sh -c "keystone-manage db_sync" keystone" command, I removed "su -" part from command as I was logged in with root user, it didn't gave me any error. I was unable to create tenant so I re-executed the steps given, but this time without removing "su -" part from command. This time everything worked fine.

Hi, I have the same mistake. When i try to create an admin user, I have this error:

An unexpected error prevented the server from fulfilling your request. (HTTP 500)

Before i introduced this command:

keystone tenant-create --name admin --description "Admin Tenant"

But i have other error before. When i introduced the command:

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

And the error was:

OperationError: (OperationError) (1130, "Host 'controller' is not allowed to connect to this MariaDB server") None None

This last error was after the configure prerequisites the OpenStack Identity service.

Please, help!
