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} -p1.2. 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=172.16.0.26:2888:38881.3. 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/myid1.4 修改 zookeeper-home 目录及子目录所属用户为 yunwei ：
chown -R yunwei:yunwei /data/docker/zookeeper-home2. 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-all2.2 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:3.4.102.3 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
