Zookeeper cluster construction under Linux

First install VMware, installed two virtual machines, the version is Centos6.5,ip, respectively, is

192.168.3.20

192.168.3.21

Then download the Zookeeper package: http://zookeeper.apache.org/, use the command TAR-ZXVF zookeeper.tar.gz to extract the extract to the/opt/soft directory

Modify the hostname vim/etc/hosts to add two entries in the Hosts file

192.168.1.20 Master

192.168.1.21 slave1

Enter zookeeper directory, create folder data, enter data, create file myid,20 and 21 myID write 1 and 2 respectively

Enter the Conf directory, there is a profile template, copy one, name Zoo.cfg, modify Zoo.cfg, the content is as follows

Datadir=/opt/soft/zookeeper-3.4.5/data (The Data directory you just created)

clientport=2181

initlimit=10

Synclimit=5

ticktime=2000

server.1=master:2888:3888 (Zookeeper will find IP based on host name)

server.2=slave1:2888:3888

Shut down the firewall (if the firewall is not turned off, after the boot, will always error);

Execute command: bin/zkserver.sh start conf/zoo.cfg, respectively zookeeper

Then: tail-300f zookeeper.out View the contents of the output, if no error, indicating the success of the start;

Next look at the cluster is the success of the build:

Execution: Bin/zkcli.sh-server master:2181 (Master and slave1, choose one)

Go to the Zookeeper Client command line below, execute LS/, will output [zookeeper], this time create a node create/test, and then view get/test, print the information

TestValue
Czxid = 0x200000005
CTime = Fri Mar 15:07:23 PST 2017
Mzxid = 0x200000005
Mtime = Fri Mar 15:07:23 PST 2017
Pzxid = 0x200000005
cversion = 0
dataversion = 0
aclversion = 0
Ephemeralowner = 0x0
Datalength = 9
Numchildren = 0

Then switch to another IP, perform execution: Bin/zkcli.sh-server master:2181, then LS/view, you can see the node that was just created on another machine test

Above all through, explain zookeeper cluster build success!
