这篇文章主要介绍了ZooKeeper3.4.10集群安装配置-Docker,集群部署配置步骤，本文给大家介绍的非常详细，对大家的学习或工作具有一定的参考借鉴价值，需要的朋友可以参考下

一. 服务器规划

主机	IP	端口	备注
b-mid-24	172.16.0.24	2181, 2888, 3888	2181：对cline端提供服务 3888：选举leader使用 2888：集群内机器通讯使用（Leader监听此端口）
b-mid-25	172.16.0.25	2181, 2888, 3888
b-mid-26	172.16.0.26	2181, 2888, 3888

二. 集群部署

注：以下步骤需要分别在三台主机操作

1. 配置

1.1 创建宿主机映射目录

				?

									mkdir /data/docker/zookeeper-home/{conf,data,logs,datalog} -p

1.2. 创建配置文件（3台zk节点配置文件一样）

vi /data/docker/zookeeper-home/conf/zoo.cfg ：

				?

									# The number of milliseconds of each tick

									tickTime=2000

									# The number of ticks that the initial 

									# synchronization phase can take

									initLimit=10

									# The number of ticks that can pass between 

									# sending a request and getting an acknowledgement

									syncLimit=5

									# the directory where the snapshot is stored.

									# do not use /tmp for storage, /tmp here is just 

									# example sakes.

									dataDir=/data

									dataLogDir=/datalog

									# the port at which the clients will connect

									clientPort=2181

									# the maximum number of client connections.

									# increase this if you need to handle more clients

									#maxClientCnxns=60

									#

									# Be sure to read the maintenance section of the 

									# administrator guide before turning on autopurge.

									#

									# http://zookeeper.apache.org/doc/current/zookeeperAdmin.html#sc_maintenance

									#

									# The number of snapshots to retain in dataDir

									#autopurge.snapRetainCount=3

									# Purge task interval in hours

									# Set to "0" to disable auto purge feature

									#autopurge.purgeInterval=1

									server.24=172.16.0.24:2888:3888

									server.25=172.16.0.25:2888:3888

									server.26=172.16.0.26:2888:3888

1.3. 配置zookeeper主机id，每个机器id不能相同，需要对应配置文件server后面的值：

				?

									echo "24" > /data/docker/zookeeper-home/data/myid

									echo "25" > /data/docker/zookeeper-home/data/myid

									echo "26" > /data/docker/zookeeper-home/data/myid

1.4 修改 zookeeper-home 目录及子目录所属用户为 yunwei ：

				?

									chown -R yunwei:yunwei /data/docker/zookeeper-home

2. 启动

2.1 开启端口

				?

									firewall-cmd --permanent --add-port=2181/tcp

									firewall-cmd --permanent --add-port=2888/tcp

									firewall-cmd --permanent --add-port=3888/tcp

									firewall-cmd --reload

									firewall-cmd --list-all

2.2 启动服务（用 yunwei 账号执行）

拉取镜像：

				?

									docker pull zookeeper:3.4.10

启动服务：

				?

									docker run -d \

									--name zookeeper \

									--network host \

									--restart=unless-stopped \

									-v /data/docker/zookeeper-home/data:/data \

									-v /data/docker/zookeeper-home/conf:/conf \

									-v /data/docker/zookeeper-home/datalog:/datalog \

									-v /data/docker/zookeeper-home/logs:/logs \

									-v /etc/localtime:/etc/localtime \

									zookeeper:3.4.10

2.3 查看服务器状态

				?

									docker exec -it zookeeper bash

									zkServer.sh status

									echo mntr | nc 127.0.0.1 2181

									zkCli.sh -server 127.0.0.1:2181

									ls /
