+++ This bug was initially created as a clone of Bug #1266027 +++ As of Liberty, openstack gate switched to pymysql driver, so it's better to use it in all openstack installers too. To switch to the new driver, database_connection string should get driver specifier as in: database_connection = mysql+pymysql://...127.0.0.1/...
Proposed https://review.openstack.org/257866 with a patch for Packstack. This requires all patches in https://review.openstack.org/#/q/status:merged+branch:master+topic:PyMySQL-driver,n,z to be included as part of OPM to provide the required support.
This bug was accidentally moved from POST to MODIFIED via an error in automation, please see mmccune with any questions
Packstack already provides pymysql support, closing.
