Specific embodiment
In order that the technical problem to be solved in the present invention, technical scheme and beneficial effect become more apparent, below in conjunction with
Drawings and Examples, the present invention will be described in further detail.It should be appreciated that specific embodiment described herein is only used
To explain the present invention, it is not intended to limit the present invention.
The invention provides a kind of method that new node adds server cluster, Fig. 1 is provided in an embodiment of the present invention new
Node adds the flow chart of the method for server cluster, as shown in figure 1, the method comprising the steps of S110 to step S140.
Step S110, obtains default nodal analysis method, and server cluster includes multiple nodes, and node all uses node mould
Type.
A node in the present embodiment can be a server, and nodal analysis method is also referred to as the collection of server cluster node
Group's adapter (ClusterAdapter) model is generally divided into primary attribute and complex attribute, can in large-scale server cluster
To use the complex attribute of nodal analysis method, complex attribute can include：The node channel logical name of node, use asynchronous channel
The complete name of node channel logical name, the logical field name of node type and clustered node node etc..
Step S120, initializes nodal analysis method, to create new node.
The nodal analysis method of initialization is needed including such as properties：
Node type name (NodeType, such as)
Node channel alias (ChannelAliasName, such as xxx)
Cluster name (ClusterAliasName, such as idc1imtest)
Host name (HostName, such as server246)
Server logic domain name (ServerDomain, such as abc.com)
IDC computer rooms title (IdcAliasName, such as idc1)
Step S130, creates the transmission channel of new node, and the structure of transmission channel is corresponding with the structure of nodal analysis method.
The form of the node channel logical name in this step be node type name-node tunnel name-host name (i.e.
NodeType-ChannelAliasName-HostName), such as as-xxx-server246.
Preferably, after connection is initiated using the transmission channel cluster for creating, can also be in server cluster by section
Vertex type is grouped.
Each node can determine the node type of the current each node for having added server cluster according to node listing
Title, such that it is able to proceed a point group by every kind of node type name, so that each node is known with same node point type
Node listing.
Step S140, new node and server cluster are connected using transmission channel.
If once connecting unsuccessful, can repeatedly be connected in this step, until new node is successfully joined server
Untill cluster.
Server in the embodiment of the present invention uses unified nodal analysis method, is easy to node to be dynamically added and leave service
Device cluster, therefore compatibility and the flexibility of server cluster are improve, meanwhile, server is sent and is deposited by same form
Storage data, are easy to be cooperated between server, improve the response speed of server cluster.
A kind of node confirmation method is the embodiment of the invention provides, is added and node due to having node in server cluster
Situations such as exiting, in order to service current all nodes exactly, it is preferable that after step S120, can be to the node of addition
Confirmed with the node for leaving.Fig. 2 is the flow chart of node confirmation method provided in an embodiment of the present invention, as shown in Fig. 2 should
Method includes：
Step S210, creates the protocol package monitor of new node and the message receiver of transmission channel, protocol package monitor
Event, node is added to leave the protocol package that event and other nodes are sent for receiving node, message receiver is used to receive section
Point list.
In the embodiment of the present invention, 2 key-value set map1 and map2 can be created, for preserving node listing, its
Middle map1 is that different node type names are the corresponding server node asynchronous channel address lists of key, and map2 is serviced for each
The channel address set of the entitled key of channel logic of device node.
Step S220, by transmission channel, the node listing of server cluster is sent to the message receiver of each node.
Preferably, group leader's node can be set in server cluster, and group leader's node is used for the section in server cluster
Point broadcast node list.
Group leader can be with the new view of broadcast node, and the renewal after message receiver receives new view of each node is preserved in itself
Node listing.Specifically, new view can be traveled through, updates the server cluster interior joint (ClusterNode)
Map1 and map2 gathers, so as to preserve newest node listing.
Step S230, relatively current version node listing and a upper node listing, generation node add event and/or node
Event is left, protocol package monitor is sent to.
Node in server cluster, can be with according to current version node listing and the difference of a upper node listing interior joint
It is determined that the node for adding and the node for leaving.
The process for comparing can be divided into following steps：
Step 1, caches the upper node listing of group membership, preserves current version node listing.
Step 2, travels through each node in current version list, if not existing the node in a upper list, it is determined that
The node is the new node for adding, and then the channel logic name of the node can be obtained from node channel address (Address)
Claim, the composition form according to the node channel logical name (is node type name-node tunnel name-host name, for example
As-xxx-server246 the node type name) can be extracted, and produces node to add event (logical name containing node channel
Title, node type name, addition event type EventType.join), and pass to protocol package monitor
(PacketListener)。
Step 3, travels through each node in a upper list, if not existing the node in current version list, really
Surely there is node to leave, and then the channel logic title of the node is obtained from node channel address (Address), according to the node
The composition form of channel logic title (is node type name-node tunnel name-host name, such as as-xxx-
Server246), the node type name can be extracted, and produces node to leave event (logical name containing node channel, section
Vertex type title, leave event type EventType.leave), and pass to protocol package monitor (PacketListener).
Preferably, after the generation node in step S230 leaves event, can retain and be sent to the letter for leaving node
Breath, issues the node again when rejoining.Specifically, may comprise steps of：
Step 1, determines that node leaves that event is corresponding to leave node.
Step 2, caching needs to be sent to the protocol package for leaving node.
Step 3, if leaving node rejoins server cluster, retransmission protocol bag.
By the embodiment of the present invention, node can be facilitated to join and depart from server cluster, improve server cluster
Flexibility.
