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 /
