CloudStack Management Server Database Initialization Failure with Galera Cluster

[anjanaprasd]

Description:
We are experiencing an issue during the database initialization of our CloudStack environment. Although the database configuration script completes successfully, the logs indicate failures during the process. We need guidance to resolve this issue and ensure proper HA setup with Galera and ProxySQL.

Environment Overview

• Database backend: MariaDB Galera Cluster
• Load balancing layer: ProxySQL
• Virtual IP managed by: Keepalived
• Cloud platform: Apache CloudStack
• CloudStack Management Servers: 3 nodes (HA setup)
• ProxySQL Servers: 3 nodes (HA setup)
• ProxySQL version : 3.0.5-60-g7e9e009
• Database: MariaDB Galera Cluster (3 nodes)
• Database Version : 10.6.25-MariaDB
• OS: AlmaLinux release 9.7
• CloudStack Version: cloudstack-management-4.22.0.0-shapeblue0.noarch
• For troubleshooting purpose firewalld is stopped

Current Setup

• We have multiple Galera nodes configured in synchronous replication mode.
• ProxySQL is deployed on two nodes with Keepalived managing a Virtual IP (VIP).
• The application connects to the database via the VIP address.
• VIP failover is working correctly.
• Database connectivity through the VIP is verified and functioning.
• Manual MySQL connections via the VIP are successful.

When I see the /etc/cloudstack/management/db. properties file it has pointed to the VIP and but in the logs it showing trying to connect local host

Additional Observation:
In the management server logs, the above entries are repeatedly printed:
Despite the service starting, port 8080 does not appear to be listening on the server initially.
After manually restarting the management service, port 8080 becomes active and accessible.

I apologize if this ticket doesn’t fully follow the usual format. I would really appreciate any guidance or advice from the team on this issue.
