# 1 环境概述 #

192.168.38.50 node1
    192.168.38.50 node2
    192.168.38.50 node3

# 2 集群搭建 #

## 2.1 拉取镜像 ##

#3台
    docker pull zookeeper

## 2.2 创建文件夹 ##

#3台
    mkdir -p /usr/local/zookeeper/conf  \
    mkdir -p /usr/local/zookeeper/data

## 2.3 创建配置文件 ##

#3台
    vi /usr/local/zookeeper/conf/zoo.cfg
    
    clientPort=2181
    dataDir=/data
    dataLogDir=/data/log
    tickTime=2000
    initLimit=5
    syncLimit=2
    autopurge.snapRetainCount=3
    autopurge.purgeInterval=0
    maxClientCnxns=60
    server.1=192.168.38.50:2888:3888
    server.2=192.168.38.51:2888:3888
    server.3=192.168.38.52:2888:3888

## 2.4 创建myid ##

#myid配置id一定要和上面配置的server.id一致
    
    #192.168.38.50
    echo 1 > /usr/local/zookeeper/data/myid
    #192.168.38.51
    echo 2 > /usr/local/zookeeper/data/myid
    #192.168.38.52
    echo 3 > /usr/local/zookeeper/data/myid

## 2.5 启动命令 ##

docker run --network host \
    -v /usr/local/zookeeper/data:/data  \
    -v /usr/local/zookeeper/conf:/conf \
    --name zookeeper -d zookeeper

## 2.6 查看 ##

#node3查看
    docker exec -it zookeeper /bin/bash
    cd /apache-zookeeper-3.7.0-bin/bin
