请求参数：

Parameter	Type	Required	Description
serverName	String	Yes	Server name
dbHost	String	Yes	Database host address to join the cluster
dbUsername	String	Yes	Database credentials (username)
dbPassword	String	Yes	Database credentials (password)
nodeIp	String	Yes	Server IP
dbName	String	Yes	Database name
failIfConnected	Boolean	No	Cause the action to completely fail if the server is already connected. Otherwise, a normal 200 status is returned without performing any action. Default: false
