XPanel User Manual

After initializing the database server, the XPanel Docker image will be installed at the user-specified location, and its container will be running. The URL and port that XPanel listens to are set in the parameter file during initialization. For example, in the sample configuration file cluster_and_node_mgr.json, XPanel is set to listen on 192.168.0.110 with the default port, so the URL for XPanel is: http://92.168.0.110:18080/KunlunXPanel. For more details, refer to the Klustron Database Server Cluster Initialization Guide.

Once initialization is complete, you can connect to XPanel using a web browser to begin cluster management and maintenance.

This chapter provides a detailed guide on how to use XPanel, including:

1. Managing Users and Privileges in XPanel

For security reasons, it is often necessary to create multiple accounts for DBAs with different privileges and roles. Each account has different privileges and can perform different operations. For details, see XPanel User Privilege Management

2. Managing Database Servers in XPanel

DBAs can add more computer servers as needed at any time by adding them to the Klustron system through XPanel. This allows the DBA to command Klustron to elastically expand the cluster to these new servers or create more Klustron clusters on these new servers. For more details, see XPanel Server Resource Management

3. Performing Cluster Management Operations in XPanel

Cluster management and maintenance operations include creating clusters, adding/removing compute/storage nodes, adding/removing storage clusters, physical/logical backups and restores, elastic scaling, online DDL and repartitioning, primary/secondary switching, and rebuilding secondary nodes. For more details, see XPanel Cluster Management, Example of Cluster Creation, Rollback, and Expansion in Xpanel, XPanel Alarm Usage Guide, XPanel Cluster Management Operation Guide, Klustron Mirror Table Feature Use Cases.
