Zookeeper fully distributed installation

The number of management zookeeper 'animals'', such as small as Hadoop, whale hbase the like, to install a fully distributed zookeeper the recording, for later use.

Extracting archive zookeeper

[root@hadoop01 /home/software]# tar -zxvf zookeeper-3.4.8.tar.gz

Modify zoo.cfg

Zoo_sample.cfg first sample copy is zoo.cfg, will be modified is zoo.cfg.

[root@hadoop01 /home/software/zookeeper-3.4.8/conf]# cp zoo_sample.cfg zoo.cfg

Modify zoo.cfg.

# Add Configuration tmp directory, which will be configured myid 
dataDir = / Home / Software / zookeeper- 3.4 . 8 / tmp 
... omitted 
# Configure three of ip, port and electoral broadcast port 
Server. 1 = 192.168 . 200.140 : 2888 : 3888 
Server. 2 = 192.168 . 200.150 : 2888 : 3888 
. Server . 3 = 192.168 . 200.160 : 2888 : 3888

Edit myid

Tmp directory needs to be created in the root directory zookeeper manually edit the digital myid the above server, three nodes 1,2,3, respectively.

# Hadoop01 node configuration 1, and so other 
[@ hadoop01 the root / Home / Software / zookeeper- 3.4 . . 8 / tmp] # CAT MyID
 1 
by You have have new new mail in / var / spool / mail / the root

Remote Copy

Zookeeper on the remote copy to the node hadoop01 hadoop02 and hadoop03, two nodes remember myid modified.

# Remote copy to hadoop02, if it is software directory, use the following command directly, you can use absolute paths 
[root @ hadoop01 / Home / software] # scp -r zookeeper- 3.4 . 8 root hadoop02 @: $ PWD 
# remote copy to hadoop03 
[root @ hadoop01 / Home / Software] # scp -r zookeeper- 3.4 . 8 root @ hadoop03: $ PWD

start up

Zookeeper enter the root directory, boot into the bin zookeeper three nodes, and view the status of three zookeeper, if 1 2 from the master, then the installation is successful.

Three start

[root@hadoop01 /home/software/zookeeper-3.4.8/bin]# ./zkServer.sh start

Check status, if started in the hadoop1, hadoop2 and hadoop3 order, a first follower, Leader is a second, a third is follower. This uses more than half of the election rules ZAB subsequent supplements.

# 第二台是leader
[root@hadoop02 /home/software/zookeeper-3.4.8/bin]# ./zkServer.sh status
ZooKeeper JMX enabled by default
Using config: /home/software/zookeeper-3.4.8/bin/../conf/zoo.cfg
Mode: leader

This completes the installation zookeeper fully distributed deployment.
