1、 decompression

cd /opt/module/tar -zxvf apache-zookeeper-3.5.5-bin.tar.gz

2、 Create data files and catalog files

stay zookeeper Create two folders under the following directory data and log

cd /opt/module/apache-zookeeper-3.5.5-bin/
mkdir data
mkdir log

3、 Copy configuration file

cd /opt/module/apache-zookeeper-3.5.5-bin/conf/
cp zoo_sample.cfg zoo.cfg

# sending a request and getting an acknowledgement

syncLimit=5

# the directory where the snapshot is stored.

# do not use /tmp for storage, /tmp here is just

# example sakes.

server.1=192.168.1.101:2888:3888
server.2=192.168.1.102:2888:3888

4、 Create a server myid

stay data Create one in the directory myid The file of , The value inside can be given any value , But with the above services server.x Corresponding

cd /opt/module/apache-zookeeper-3.5.5-bin/data/touch myid

5、 Cluster copy

scp -r /opt/module/apache-zookeeper-3.5.5-bin [email protected]:/opt/module/apache-zookeeper-3.5.5-bin
scp -r /opt/module/apache-zookeeper-3.5.5-bin [email protected]:/opt/module/apache-zookeeper-3.5.5-bin

6、 colony myid change

Go to each node , modify myid value

Add the cluster system environment variable ：

vi /etc/profile

export ZOOKEEPER_HOME=/opt/module/apache-zookeeper-3.5.5-bin

export PATH=$PATH:$ZOOKEEPER_HOME/bin

Save system environment variables ：

source /etc/profile

Turn off the cluster firewall

Cluster start ：

Go to each node and start ：

cd /opt/module/apache-zookeeper-3.5.5-bin
zkServer.sh start
zkServer.sh status

zkCli Connection verification ：

zkCli.sh -server hadoop100:2181
