How to install stand-alone zookeeper for ubuntu

This post is about how to install the standalone version of zookeeper on ubuntu. Xiaobian thinks it is quite practical, so share it with everyone for reference. Let's follow Xiaobian and have a look.

Download Zookeeper

Go to Apache and download Zookeeper. I downloaded Zookeeper-3.6.5.tar.gz.

Unpack installation

#Decompress

$sudo tar xzvf zookeeper-3.6.5.tar.gz

#Copy the extracted zookeeper-3.6.5 directory to/usr/local/lib

$sudo cp -r zookeeper-3.6.5 /usr/local/lib

Modify Zookeeper configuration

#Switch to the conf directory under the Zookeeper installation directory

$cd /usr/local/lib/zookeeper-3.6.5/conf

#Copy Sample Configuration as Profile

$cp zoo_sample.cfg zoo.cfg

###Modify zookeeper data storage directory to/var/local/zookeeper###

#New directory/usr/local/zookeeper

$sudo mkdir /var/local/zookeeper

#Modify zoo.cf file to dataDir =/var/local/zookeeper instead of dataDir=/tmp/zookeeper

$sed -i "s/dataDir=\/tmp\/zookeeper/dataDir=\/var\/local\/zookeeper/g" zoo.cfg

Starting and stopping Zookeeper

#Switch to bin directory

$cd /usr/local/lib/zookeeper-3.6.5/bin

#Start Zookeeper service

$./ zkServer.sh start

#Start Zookeeper client, if output sample content indicates success

$./ zkCli.sh

....

[zk: localhost:2181(CONNECTED) 0]

#Show root directory

$ [zk: localhost:2181(CONNECTED) 0] ls /

[zookeeper]

[zk: localhost:2181(CONNECTED) 1]

#Stop Zookeeper service

$./ zkServer.sh stop
