This article introduces the relevant knowledge of "the steps of building a zookeeper-3.4.6 cluster". Many people will encounter such a dilemma in the operation of actual cases, so let the editor lead you to learn how to deal with these situations. I hope you can read it carefully and be able to achieve something!

We use zookeeper-3.4.6 to build zookeeper clusters with three DELL servers in hardware (firewalls have been turned off and ssh mutual trust has been configured):

192.168.4.33 bi3

192.168.4.34 bi4

192.168.4.35 bi5

1. Extract the zookeeper-3.4.6 installation package to the / home/hadoop/work directory: / home/hadoop/work/zookeeper-3.4.6

two。 Configure conf/zoo.cfg

# the directory where the snapshot is stored.# do not use / tmp for storage, / tmp here is just # example sakes.dataDir=/home/hadoop/work/zookeeper-3.4.6/var/datadataLogDir=/home/hadoop/work/zookeeper-3.4.6/var/datalog# the port at which the clients will connectclientPort=2181server.1=bi3:2888:3888server.2=bi4:2888:3888server.3=bi5:2888:3888

3. Create a new directory

Mkdir / home/hadoop/work/zookeeper-3.4.6/var/datamkdir / home/hadoop/work/zookeeper-3.4.6/var/datalog

4. Edit / home/hadoop/work/zookeeper-3.4.6/var/data/myid, the contents of the three machines are as follows:

192.168.4.33 bi31192.168.4.34 bi42192.168.4.35 bi53

Start the zookeeper cluster and execute the following commands on each of the three machines

/ home/hadoop/work/zookeeper-3.4.6/bin/zkServer.sh start

Verify that the cluster is available

[hadoop@bi5 apps] $/ home/hadoop/work/zookeeper-3.4.6/bin/zkCli.sh-server 127.0.0.1 purl 2181

Enter the client command line mode of zookeeper, create / zktest in the root directory, and check to see if it has been created successfully

[zk: 127.0.0.1 create 2181 (CONNECTED) 4] create / zktest testCreated / zktest [zk: 127.0.0.1 create 2181 (CONNECTED) 5] ls / [consumers, zktest, rmstore, mytest, spark, yarn-leader-election, spark-test, controller_epoch, dubbo, hbase, hadoop-ha, zookeeper, admin, config Brokers] [zk: 127.0.0.1 CONNECTED 2181 (CONNECTED) 6] get / zktesttestcZxid = 0xf0006967bctime = Mon Feb 15 17:19:32 CST 2016mZxid = 0xf0006967bmtime = Mon Feb 15 17:19:32 CST 2016pZxid = 0xf0006967bcversion = 0dataVersion = 0aclVersion = 0x0dataLength = 4numChildren = 0 "zookeeper-3.4.6 Cluster Building steps" ends here Thank you for your reading.
