Create zookeeper user

$ sudo adduser zookeeper


Configure zookeeper

To make an ensemble with Master-slave architecture,  we needed to have odd number of zookeeper server .i.e.{1, 3 ,5,7....etc}. 

Now, Create the directory zookeeper under /var/lib folder which will serve as Zookeeper data directory and create another zookeeper directory under /var/log where all the Zookeeper logs will be captured. Both of the directory ownership need to be changed as zookeeper.

...


Create the server id for the ensemble. Each zookeeper server should have a unique number in the myid file within the ensemble and should have a value between 1 and 255.To make an ensemble with Master-slave architecture,  we needed to have odd number of zookeeper server .i.e.{1, 3 ,5,7....etc}. 

In Node1

$ sudo sh -c "echo '1' > /var/lib/zookeeper/myid"

...


Edit zoo.cfg and the below


$ vi zoo.cfg


dataDir=/var/lib/zookeeper
server.1=node1:2888:3888
server.2=node2:2888:3888
server.3=node3:2888:3888


Now, do the below changes in log4.properties file as follows.

$ vi log4j.properties


zookeeper.log.dir=/var/log/zookeeper 
zookeeper.tracelog.dir=/var/log/zookeeper 
log4j.rootLogger=INFO, CONSOLE, ROLLINGFILE

...

$ /home/zookeeper/zookeeper-3.4.13/bin/zkServer.sh status
