环境搭建步骤

一　准备

Docker环境（centos7 + docker1.12.1）

zookeeper 3.4.9 wget http://mirrors.hust.edu.cn/apache/zookeeper/stable/zookeeper-3.4.9.tar.gz

遗留问题

二　基础镜像制作

Dockerfile

FROM centos:6.7MAINTAINER loomz loomz@163.comENV REFRESHED_AT 2017-03-15ENV JAVA_HOME /usr/java/defaultENV CLASSPATH .:$JAVA_HOME/lib:$JAVA_HOME/jre/libENV PATH $JAVA_HOME/bin:$JAVA_HOME/jre/bin:$PATHENV ZK_HOME /opt/zookeeper/defaultADD jdk1.6.0_45.tar.gz /usr/java/jdk1.6.0_45RUN ln -s /usr/java/jdk1.6.0_45 $JAVA_HOMEADD zookeeper-3.4.9.tar.gz /opt/zookeeper/RUN ln -s /opt/zookeeper/zookeeper-3.4.9 $ZK_HOMEEXPOSE 2181ENTRYPOINT ["/opt/zookeeper/default/bin/zkServer.sh", "start-foreground", "/etc/zookeeper/zoo.cfg"]

三　容器启动

配置文件zoo.cfg

tickTime=2000dataDir=/var/lib/zookeeperclientPort=2181initLimit=5  syncLimit=2  server.1=172.17.0.2:2888:3888  server.2=172.17.0.3:2888:3888  server.3=172.17.0.4:2888:3888

容器启动脚本start-s1.sh start-s2.sh start-s3.sh

#!/bin/bashdocker run -d --restart always -h zookeeper-server1 --name zookeeper-server1 -v /home/loomz/dockerfiles/zk/conf/:/etc/zookeeper/:rw -v /home/loomz/dockerfiles/zk/tmp_server1:/var/lib/zookeeper/ zookeeper:v3.4.9

start-s2.sh start-s3.sh　对应更改server1 为　server2 server 3

在tmp_server1／tmp_server２／tmp_server３文件夹中建立myid文件在，内容对应数字　1 2 3 (因为上面配置为server.1 server.2 server.3)

四　启动后验证

同时启动start-s1.sh start-s2.sh start-s3.sh后进入容器验证zk状态

docker exec -it  zookeeper-server1   /bin/bash/opt/zookeeper/default/bin/zkServer.sh status /etc/zookeeper/zoo.cfgZooKeeper JMX enabled by defaultUsing config: /etc/zookeeper/zoo.cfgMode: leader
