You also need to make sure that the java environment is equipped on each machine.

Tar zxvf zookeeper-3.4.6.tar.gz-C / opt/ln-s / opt/zookeeper-3.4.6/ / opt/zookeeper configuration zookeeper

Copy / opt/zookeeper/conf/zoo_sample.cfg to / opt/zookeeper/conf/zoo.cfg

Cp / opt/zookeeper/conf/zoo_sample.cfg / opt/zookeeper/conf/zoo.cfg

Configure the zoo.cfg file
