Verifying the Control Center configuration
- Log in to the primary node as root, or as a user with superuser privileges.
- In a separate window, log in to the secondary node as root, or as a user with superuser privileges.
On both nodes, compute the checksum of the Control Center configuration file.
- If the result is identical on both nodes, the configurations are identical. Do not perform the next step.
- If the result is not identical on both nodes, there may be a difference in their configurations; proceed to the next step.
On both nodes, display the customized variables, if necessary.
