## 单点部署 ##

一、下载最新的安装包

我们这里下载的是zookeeper-3.5.4-beta.tar.gz

二、解压到/opt/zookeeper目录下

![70][]

三、修改配置文件zoo\_sample.cfg

dataDir=/opt/zookeeper/zookeeper-3.5.4-beta/data

四、启动

sh zkServer.sh start  ../conf/zoo_sample.cfg

PS其他命令

sh zkServer.sh status ../conf/zoo_sample.cfg 查看状态
    sh zkServer.sh stop ../conf/zoo_sample.cfg 关闭
    sh zkCli.sh  进入客户端
    sh zkCli.sh -server 192.168.37.2  连接其他服务器

五、zookeeper UI

①maven下载地址

https://github.com/DeemOpen/zkui

②编译

进入C:\\Users\\yangjie\\Desktop\\zkui-master文件夹，执行

mvn clean package

生成文件，zkui-2.0-SNAPSHOT-jar-with-dependencies.jar

③修改config.cfg文件

zkServer=192.168.37.137:2181

④将jar包跟配置文件上传到服务器路径/opt/zookeeper/zkUI下 ，启动

java -jar zkui-2.0-SNAPSHOT-jar-with-dependencies.jar &

⑤开放zkUI默认的9090端口

⑥访问

http://192.168.37.137:9090

默认账户密码  admin/manager

##  集群部署 ##

1.准备三台主机，ip分别为192.168.225.128,192.168.225.129,192.168.225.130

2.每台主机上面安装zk的步骤与上面的单点部署的步骤一致

3.配置文件直接重命名为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=/opt/zk/apache-zookeeper-3.5.6-bin/data
    dataLogDir=/opt/zk/apache-zookeeper-3.5.6-bin/log
    # 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.1=192.168.225.128:2888:3888
    server.2=192.168.225.129:2888:3888
    server.3=192.168.225.130:2888:3888

server.A=B：C：D：其中 A 是一个数字，表示这个是第几号服务器；B 是这个服务器的 ip 地址；C 表示的是这个服务器与集群中的 Leader 服务器交换信息的端口；D 表示的是万一集群中的 Leader 服务器挂了，需要一个端口来重新进行选举，选出一个新的 Leader，而这个端口就是用来执行选举时服务器相互通信的端口。如果是伪集群的配置方式，由于 B 都是一样，所以不同的 Zookeeper 实例通信端口号不能一样，所以要给它们分配不同的端口号

4.开放每台主机的2181,2888,3888端口

5.分别启动 sh zkServer.sh start

ZooKeeper JMX enabled by default
    Using config: /opt/zk/apache-zookeeper-3.5.6-bin/bin/../conf/zoo.cfg
    Starting zookeeper ... STARTED

6.查看状态 sh zkServer.sh status

ZooKeeper JMX enabled by default
    Using config: /opt/zk/apache-zookeeper-3.5.6-bin/bin/../conf/zoo.cfg
    Client port found: 2181. Client address: localhost.
    Mode: leader

集群部署成功
