安装zookeeper

一、搭建前准备

192.168.1.99 sdw1

192.168.1.98 sdw2

192.168.1.97 sdw3

二、搭建

1、各主机修改/etc/hosts，/etc/hostname文件

/etc/hosts

127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4
::1 localhost localhost.localdomain localhost6 localhost6.localdomain6

192.168.1.99 sdw1
192.168.1.98 sdw2
192.168.1.97 sdw3

/etc/hostname

sdw1

重启

2、各主机安装jdk

# yum install java

3、安装zookeeper

（1）下载安装包

# wget -c https://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.6.2/apache-zookeeper-3.6.2-bin.tar.gz
# tar xf apache-zookeeper-3.6.2-bin.tar.gz -C /usr/local/
# mv apache-zookeeper-3.6.2-bin zookeeper

（2）修改配置文件

cd /usr/local/zookeeper/conf
cp -r ./zoo_sample.cfg zoo.cfg
cat zoo.cfg | grep -v "^#"

vi zoo.cnf

tickTime=2000
initLimit=10
syncLimit=5
dataDir=/data/zookeeper/data
dataLogDir=/data/zookeeper/logs
clientPort=2181

server.1=sdw1:2888:3888
server.2=sdw2:2888:3888
server.3=sdw3:2888:3888

scp -r /usr/local/zookeeper/ sdw2:/usr/local/

scp -r /usr/local/zookeeper/ sdw3:/usr/local/

#两主机都运行

mkdir -p /data/zookeeper/data/

vi /data/zookeeper/data/myid

1 //与zoo.cfg配置文件中对应，sdw为server.1，所以该处填写为1

vi /etc/profile

#Zookeeper Environment
export ZK_HOME=/usr/local/zookeeper
export PATH=$PATH:$ZK_HOME/bin

开启zk（注意三个机器都要开启，之后再查看zk状态）
