二 ：集群搭建 
1.写配置文件zoo.cfg

#nod1tickTime=2000dataDir=/opt/zookeeper/dataclientPort=2181initLimit=5syncLimit=2server.1=*.*.*.*:2888:3888server.2=*.*.*.*:2888:3888server.3=*.*.*.*:2888:3888myid=1#nod2tickTime=2000dataDir=/opt/zookeeper/dataclientPort=2181initLimit=5syncLimit=2server.1=*.*.*.*:2888:3888server.2=*.*.*.*:2888:3888server.3=*.*.*.*:2888:3888myid=2#nod3tickTime=2000dataDir=/opt/zookeeper/dataclientPort=2181initLimit=5syncLimit=2server.1=*.*.*.*:2888:3888server.2=*.*.*.*:2888:3888server.3=*.*.*.*:2888:3888myid=3

2.分别启动容器

docker run --name zookeeper --net host -v /showcase/zookeeper/zoo.cfg:/opt/zookeeper/conf/zoo.cfg --restart=always -d zookeeper:latestdocker run --name zookeeper --net host -v /showcase/zookeeper/zoo.cfg:/opt/zookeeper/conf/zoo.cfg --restart=always -d zookeeper:latestdocker run --name zookeeper --net host -v /showcase/zookeeper/zoo.cfg:/opt/zookeeper/conf/zoo.cfg --restart=always -d zookeeper:latest
