Anyone faced the same issue? Can someone help with me this?

Hello,
Please look through the installation logs to see if there were any errors with the database. Near the end you can see the
CantStartEngineError: No sql_connection parameter is established
If the same error exists in the main node it is a problem with the overall OpenStack process. If it only exists when a node is added then it may be a bug or some other issue to track down.Please also include other errors you find in the installation logs.

Thank you for your quick response.
Below is the summary of the installation [stack.sh] log found under /opt/stack/logs
I do not see any error mentioned here..
The script completed successfully.0 -
Please let me know if there is any other log file that needs to be checked..

Hello,
In the command output you pasted it shows that the stack.sh command completed in 660 seconds. But there may be other errors we do not see in this output. Could you grep -i for err messages in the /opt/stack/logs/stack.sh.log* file. The very first line in the output mentions the log file to view.0
