cm_install and cm_uninstall Tools

The cm_install tool can be used to deploy CMs in the MogDB database cluster. The cm_uninstall tool can be used to uninstall CMs from the MogDB database cluster without affecting the DN cluster.

Precautions

• After cm_install is executed, the cluster is started by default.
• This tool must be used as an individual user.

Prerequisites

• The OM tool is required for installing the MogDB cluster.
• Generally, the cluster installed using the OM tool can ensure that mutual trust exists between nodes in the cluster.
• The version of the MogDB cluster to be installed is the same as that of the CM to be installed.
