SOLR Cloud(1)Zookeeper

SOLR Cloud(1)Zookeeper

1 Prepare the Environment
First of all, set up JDK
I already have the latest JDK version on my ubuntu system.
> java -version
java version "1.8.0_77"
Java(TM) SE Runtime Environment (build 1.8.0_77-b03)
Java HotSpot(TM) 64-Bit Server VM (build 25.77-b03, mixed mode)

2 Set up Zookeeper Cluster

Latest zookeeper and set up cluster
> wget http://apache.mirrors.tds.net/zookeeper/stable/zookeeper-3.4.8.tar.gz

Unzip and place in the right directory
Prepare the configuration files as follow:
>cat conf/zoo1.cfg
server.1=ubuntu-master:2888:3888
server.2=ubuntu-dev1:2888:3888
server.3=ubuntu-dev2:2888:3888

>cat conf/zoo2.cfg
server.1=ubuntu-master:2888:3888
server.2=ubuntu-dev1:2888:3888
server.3=ubuntu-dev2:2888:3888

>cat conf/zoo3.cfg
server.1=ubuntu-master:2888:3888
server.2=ubuntu-dev1:2888:3888
server.3=ubuntu-dev2:2888:3888

Set up the myid on all the servers
> cat /tmp/zookeeper/myid
1

> cat /tmp/zookeeper/myid
2

> cat /tmp/zookeeper/myid
3

Start 3 nodes
> zkServer.sh start zoo1.cfg
> zkServer.sh start zoo2.cfg
> zkServer.sh start zoo3.cfg

One way to check if it is running
> jps
32581 QuorumPeerMain
32663 Jps

Another way to check who is the leader/follower
> echo stat | nc localhost 2181 | grep Mode
Mode: follower

> echo stat | nc localhost 2181 | grep Mode
Mode: leader

Now, the zookeeper cluster is running there.
