To install Zookeeper, first download Zookeeper from this link:

http://zookeeper.apache.org/releases.html

Then go to the directory where this file is downloaded and extract the Zookeeper files:

$ cd Downloads

$ tar -xvf zookeeper-3.4.12.tar.gz

Now you must configure Zookeeper. To do this, go the Zookeeper directory and create a new directory name data.

$ cd conf

$ nano zoo.cfg

Save and exit.
