Hello,

I am having issues with installation of OpenStack with Centos7...

I made it all the way to verify operation in networking service section without any errors. Performing the following command gives me an error:

$ neutron ext-list

An unexpected error prevented the server from fulfilling your request. (HTTP 500) (Request-ID: req-c7ac0bc8-8e49-4151-b14a-1ca2c6f6fa70)

During troubleshooting I went back tracked to the keystone configuration section. I get the same error when attempting to create users, domains, etc.

I'm not sure if this is the issue but I see the following in the keystone.log:

2016-11-17 15:26:03.430 11026 ERROR keystone.common.wsgi OperationalError: (pymysql.err.OperationalError) (1040, u'Too many connections') 2016-11-17 15:26:03.430 11026 ERROR keystone.common.wsgi 2016-11-17 15:34:22.098 11025 INFO keystone.common.wsgi [req-bd630904-5b11-42c8-a12a-e57e2a0e3f77 - - - - -] GET http://controller:35357/v3/ 2016-11-17 15:34:23.060 11029 WARNING keystone.assignment.core [-] Deprecated: Use of the identity driver config to automatically configure the same assignment driver has been deprecated, in the "O" release, the assignment driver will need to be expicitly configured if different than the default (SQL). 2016-11-17 15:34:23.333 11029 INFO keystone.common.wsgi [req-c7ac0bc8-8e49-4151-b14a-1ca2c6f6fa70 - - - - -] POST http://controller:35357/v3/auth/tokens 2016-11-17 15:34:23.347 11029 ERROR keystone.common.wsgi [req-c7ac0bc8-8e49-4151-b14a-1ca2c6f6fa70 - - - - -] (pymysql.err.OperationalError) (1040, u'Too many connections')

Any help is appreciated.

in your error prompt include : (pymysql.err.OperationalError) (1040, u'Too many connections')

in server where installed mysql,

netstat -anl|grep :3306

or modify your mysql configure file :my.cnf

[mysqld]
max_connections = 20000
max_user_connections = 19800
