It asks, sends a notification message to the node server, the node server and the second central server is notified to establish connection.
Server cluster control method of the embodiment of the present invention, by the node server point for establishing connection for request in cluster
With the second central server, so that the first central server in cluster need not directly be connect with node server, in this way can
Mitigate the load of the first central server, so that the operation of server cluster is more stable.
On the other hand, a kind of server cluster control method of the embodiment of the present invention, comprising: the node in server cluster
Server sends connection request to the first central server；The node server receives first central server according to institute
State the notification message of connection request return；It include the information of the second central server in the notification message；The node clothes
Device be engaged according to the notification message, establishes connection with second central server.
Server cluster control method of the embodiment of the present invention, the node server in cluster pass through in first into cluster
Central server sends connection request to obtain the second central server information, and establishes connection with second central server,
It can reduce the load of the first central server in this way, so that the operation of server cluster is more stable.
On the other hand, the embodiment of the present invention provides a kind of central server for server set group control, comprising: the
One receiving unit, for receiving the connection request of the transmission of the node server in server cluster；First notification unit is used for root
According to the connection request that the node server is sent, sends a notification message to the node server, notify the node serve
Device and the second central server establish connection.
The embodiment of the present invention is used for the central server of server set group control, by establishing connection for request in cluster
Node server distributes the second central server, so that the central server in cluster need not directly be connect with node server,
It can reduce the load of central server in this way, so that the operation of server cluster is more stable.
On the other hand, the node server in a kind of server cluster of the embodiment of the present invention, comprising: the first request is sent
Unit sends connection request for the first central server into server cluster；First notification receiving unit, for receiving
The notification message that first central server is returned according to the connection request；It include the second center in the notification message
The information of server；First connection establishment unit, the notification message for being received according to first notification receiving unit, with
Second central server establishes connection.
Node server in server cluster of the embodiment of the present invention is sent by the first central server into cluster
Connection request establishes connection with second central server to obtain the second central server information, can reduce in this way
The load of first central server, so that the operation of server cluster is more stable.
