You can download e.g. wget apache.spd.co.il/zookeeper/current/… etc blog.redbranch.net/2018/04/19/zookeeper-install-on-centos-7 – Ayeshaayin

Answer 1

You have to add the repo that contains zookeeper. You can do this with:

yum install https://archive.cloudera.com/cdh5/one-click-install/redhat/7/x86_64/cloudera-cdh-5-0.x86_64.rpm

Afterwards you can install zookeeper normally.

See the documents here:

Answer 2

An alternative answer if you don't want to install a 3rd party repo from cloudera you could use the Apache Bigtop repo. Apache being the actual maintainer of Zookeeper.

As of writing it's this repo file on CentOS 7.

This will let you install Zookeeper by simply running yum install zookeeper.

Unfortunately that package does not include a systemd service file so I had to write my own, but that's not very hard.

[Unit]
Description=Zookeeper
After=syslog.target

[Service]
SyslogIdentifier=zookeeper
TimeoutStartSec=10min
Type=forking
ExecStart=/usr/lib/zookeeper/bin/zkServer.sh start
ExecStop=/usr/lib/zookeeper/bin/zkServer.sh stop

[Install]
WantedBy=multi-user.target

You can name the file zookeeper.service, place it in /etc/systemd/system/, and set permissions as chmod 664 /etc/systemd/system/zookeeper.service (see: access.redhat.com/documentation/en-us/red_hat_enterprise_linux/…) – Tachymetry
