Step 101, distributed coordination system host node receive new network access node send networking request message, described networking request message includes the Internet protocol IP address of described new network access node.
Distributed coordination system in the embodiment of the present invention refers to ZooKeeper cluster network. Node in ZooKeeper cluster network has two crucial roles: host node (also referred to as Leader) and from node (also referred to as Follower). In whole ZooKeeper cluster network running, only one of which Leader, other are all from node, and ZooKeeper adopts election algorithm to select a Leader. Leader is generally the node that ZooKeeper cluster interior joint sequence number is minimum. If Leader in running is out of joint for ZooKeeper cluster network, system can adopt this election algorithm again to select a Leader. How ZooKeeper cluster network specifically elects Leader, is referred to be typically implemented mode, is not detailed at this.
The host node that described host node is this ZooKeeper cluster network (Leader) of the embodiment of the present invention.
Step 102, described host node are described new network access node distribution primary nodal point mark according to described networking request message, and in the configuration file of described host node, increasing by the first corresponding relation, described first corresponding relation includes the IP address of described primary nodal point mark and described new network access node.
Step 103, described host node increase described first corresponding relation in nodal information set, the nodal information set after being updated so that described distributed coordination system from the configuration file of node, increase described first corresponding relation from node described.
Alternatively, the host node of described distributed coordination system also includes before receiving the networking request message that new network access node sends:
Described host node prestores described nodal information set; Described nodal information set includes the node identification of described host node and the corresponding relation of the IP address of described host node, and the corresponding relation of described node identification from node and the described IP address from node.
In ZooKeeper cluster network, all of node is as a generally Distributed Application offer service, cluster network interconnects between each node, so, when configuration ZooKeeper cluster network, each node comprises the corresponding relation of the node identification of other each node and IP address in ZooKeeper cluster network. As:
The corresponding server.1 of host1 (192.168.0.179);
The corresponding server.2 of host2 (192.168.0.178);
The corresponding server.3 of host3 (192.168.0.177).
On each node that ZooKeeper cluster network is disposed, all preserve configuration file (zoo.cfg), if ZooKeeper cluster network has new network access node, then need to revise the configuration file of each node.
Assume that the content in configuration file (zoo.cfg) original on node 1 is as follows:
TickTime=2000
DataDir=/var/lib/ZooKeeper
ClientPort=2181
InitLimit=5
SyncLimit=2
Server.1=host1:port1:port2
Server.2=host2:port1:port2
Server.3=host3:port1:port2
Wherein:
TickTime: represent between ZooKeeper cluster network interior joint or maintain the interval of heart beating, unit millisecond between client and node.
DataDir: represent the catalogue preserving data and daily record in ZooKeeper cluster network.
ClientPort: represent that client connects the port of ZooKeeper cluster network interior joint.
InitLimit: represent that configuration ZooKeeper cluster network accepts the longest heartbeat time interval number when client initialization connects, exceed and show client connection failure; " 5 " represent 5 tickTime, and total time span is exactly the 5*2000=10 second.
SyncLimit: sending message, request and response time length between mark Leader and Follower, the longest time span that not can exceed that how many tickTime, total time span is exactly the 2*2000=4 second.
