一、部署准备

1. 安装介质

• zookeeper-3.4.13：http://mirror.bit.edu.cn/apache/zookeeper/zookeeper-3.4.13/zookeeper-3.4.13.tar.gz

2. 主机规划

192.168.233.134	host14	
192.168.233.133	host15
192.168.233.136 host16

---

二、Zookeeper部署

1. 上传解压介质

scp -r zookeeper-3.4.13.tar.gz host16:/opt/tools/hadoop-system/
ssh host16

cd /opt/tools/hadoop-system/
mkdir -p /opt/apache/zookeeper/
tar zxf ./zookeeper-3.4.13.tar.gz -C /opt/apache/zookeeper/

---

2. 配置ZK

cd /opt/apache/zookeeper/
mkdir data dataLog 
cd /opt/apache/zookeeper/zookeeper-3.4.13/

2.1 配置 zoo.cfg

mv ./conf/zoo_sample.cfg ./conf/zoo.cfg
vim ./conf/zoo.cfg

tickTime=2000
initLimit=10
syncLimit=5
clientPort=2181
dataDir=/opt/apache/zookeeper/data
dataLogDir=/opt/apache/zookeeper/dataLog
server.1=host14:2888:2889
server.2=host15:2888:2889
server.3=host16:2888:2889

 

2.2 配置 zkEnv.sh

vim ./bin/zkEnv.sh

ZOO_LOG_DIR="/opt/apache/zookeeper/data"

ZOO_LOG4J_PROP="INFO,ROLLINGFILE"

2.3 配置 zkServer.sh

vim ./bin/zkServer.sh

ZOOBIN=`readlink -f "${BASH_SOURCE-$0}"`

SERVER_JVMFLAGS="-Xms1024m -Xmx1024m"

2.4 配置 zkCli.sh

vim ./bin/zkCli.sh

ZOOBIN=`readlink -f "${BASH_SOURCE-$0}"`

---

3. 部署ZK集群

cd /opt/apache

scp -r /opt/apache/zookeeper host14:/opt/apache/
scp -r /opt/apache/zookeeper host15:/opt/apache/

3.1  配置myid
cd /opt/apache/zookeeper/data 

(1) host14
echo 1 > myid
(2) host15
echo 2 > myid
(3) host16
echo 3 > myid

---

4. 配置ZK环境变量

4.1 配置.bash_profile

$ vim ~/.bash_profile

# ZK_HOME
export ZK_HOME=/opt/apache/zookeeper/zookeeper-3.4.13
export PATH=$PATH:$ZK_HOME/bin

4.2 立即生效

$ source ~/.bash_profile

---

5. 启动ZK

5.1 启动

(1) host14
zkServer.sh start
(2) host15
zkServer.sh start
(3) host16
zkServer.sh start

5.2 验证启动

(1) host14
zkServer.sh status

(2) host15
zkServer.sh status

(3) host16
zkServer.sh status
