How to carry out zookeeper port description, in response to this problem, this article details the corresponding analysis and solution, hoping to help more small partners who want to solve this problem find a simpler and easier way.
Zookeeper has three ports (can be modified)
1、2181
2、3888
3、2888
Two or three ports.
1. 2181: Provide services to cline end
2.3888: Election leader use
3. 2888: Communication between machines in the cluster (Leader listens on this port)
III. Pay attention to deployment
1. Single machine single instance, as long as the port is not occupied
2. Stand-alone pseudo-cluster (stand-alone, multiple instances deployed), three ports must be modified to different groups
Myid1 :2181, 3888, 2888
myid2 : 2182,3788,2788
myid3 : 2183,3688,2688
Cluster (one machine deploys one instance)
4. The cluster is greater than or equal to 3 cardinal numbers, such as 3, 5, 7... Not too many, cluster machines too many elections and data synchronization time-consuming, unstable. At present, I think three elections +N stations observe is very good.
