Linux zookeeper installation tutorial, linuxzookeeper tutorial

First install jdk

Then download

Because zookeeper is elected in half, an odd number of nodes are usually installed. The machine list is as follows:

192.168.33.11

192.168.33.12

192.168.33.13

1. Decompress tar-zxvf zookeeper-3.4.5.tar.gz

Mvzookeeper-3.4.5 ../zookeeper

2. modify configuration

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

Vi zoo. cfg

Modify:

TickTime = 2000

InitLimit = 10

SyncLimit = 5

DataDir =/usr/local/zookeeper/data

DataLogDir =/usr/local/zookeeper/logs

ClientPort = 2181

Server.1 = 192.168.33.11: 2881: 3881

Server.2 = 192.168.33.12: 2882: 3882

Server.3 = 192.168.33.13: 2883: 3883

Open the Firewall:

Vi/etc/sysconfig/iptables

# Zookeeper

-A input-m state -- state NEW-m tcp-p tcp -- dport 2181-j ACCEPT

-A input-m state -- state NEW-m tcp-p tcp -- dport 2881-j ACCEPT

-A input-m state -- state NEW-m tcp-p tcp -- dport 3881-j ACCEPT

Service iptables restart

The vi/usr/local/zookeeper/data/myid value is 1.

Start./bin/zkServer. sh start

Disable./bin/zkServer. sh stop

Jps
