First download from zookeeper official website
http://zookeeper.apache.org/releases.html
Choose the appropriate version
Just unzip the file directly in the system
I downloaded the zookeeper-3.4.8.tar.gz version
decompress
gunzip –c zookeeper-3.4.8.tar.gz
tar -xvf zookeeper-3.4.8.tar
Then go to the conf folder in the zookeeper file
According to the zoo_sample.cfg file, copy a zoo.cfg file and configure it
