Single node installation reference: http://blog.sina.com.cn/s/blog_6f6bc30e0101pb13.html

Zookeeper cluster installation

Note: 1. Note that / etc/hosts needs to be configured 2. Pay attention to opening the iptables communication between each node

The configuration file for the three hosts is as follows: [root@DB-23 zookeeper] # more conf/zoo.cfg | grep-v "#"

TickTime=2000

InitLimit=10

SyncLimit=5

DataDir=/data/app/zookeeper/data

ClientPort=2181

Autopurge.purgeInterval=1

Server.1=10.32.7.113:2889:3888

Server.2=10.32.7.112:2889:3888

Server.3=10.32.7.111:2889:3888

Modifying the myidmyid of each machine needs to correspond to the number after the server in the configuration file

[root@DB-23 data] # pwd

/ data/app/zookeeper/data

[root@DB-23 data] # more myid

1 [root@DB-22 data] # pwd

/ data/app/zookeeper/data

[root@DB-22 data] # more myid

two

[root@DB-21 data] # pwd

/ data/app/zookeeper/data

[root@DB-21 data] # more myid

three

Start the zookeeper of each machine and verify [root@DB-21 conf] # zk-server status

JMX enabled by default
