Created attachment 1241471 [details] "journalctl -u os-collect-config" from Controller0 Description of problem: I set a FQDN name for undercloud in undercloud.conf but this does not update dhcp_domain in "/etc/nova/nova.conf" and "/etc/neutron/dhcp_agent.ini" (where they default to "localdomain") when I install the undercloud. When you set the "CloudDomain" (normally same domain as in the undercloud FQDN) in your overcloud parameters (required for SSL/TLS) it fails the deployment at or just after Step2.2 where MySQL/Galerra fails to start with cannot open socket. ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' Version-Release number of selected component (if applicable): RHOSP10d How reproducible: Steps to Reproduce: 1. Deploy undercloud 2. Configure overcloud with SSL and set "CloudDomain" 3. Deploy overcloud with 3 controllers Actual results: Deployment fails at or just after Step2.2 due to MySQL/Galerra failing to start ERROR 2002 (HY000): Can't connect to local MySQL server through socket '/var/lib/mysql/mysql.sock' Expected results: Additional info: If you do not set CloudDomain or set it to "localdomain" it works. Workaround: On the undercloud manually update dhcp_domain in "/etc/nova/nova.conf" and "/etc/neutron/dhcp_agent.ini".
You might need to set the CloudName* options when you deploy. For example: [stack@instack ~]$ cat /home/stack/templates/domain.yaml parameter_defaults: CloudDomain: test.example.com CloudName: overcloud.test.example.com CloudNameInternal: overcloud.internalapi.test.example.com CloudNameStorage: overcloud.storage.test.example.com CloudNameStorageManagement: overcloud.storagemgmt.test.example.com CloudNameCtlplane: overcloud.ctlplane.text.example.com

The is issue is the DHCP server on the director not giving the client a domain as it has an empty domain set, resulting in MySQL/Galerra failing to start: "ERROR 2002 (HY000): Can't connect to local MySQL server through socket..."
We faced the same issue running OSP10 and RHEL7.3. If only setting CloudDomain parameter, MySQL/Galera fails to start on controllers during deploy. Just removed CloudDomain option from YAML files and performed a new deploy to get things working again. We'll try the suggested workaround soon. Thanks.
