## 系统环境 ##

*  Ubuntu 16.04 LTS
 *  zookeeper-3.5.2-alpha.tar.gz

## 安装步骤 ##

1.下载ZooKeeper tar包并解压

tar -zxvf zookeeper-3.5.2-alpha.tar.gz

2.进入解压后文件夹下的conf目录(/opt/apps/zookeeper/zookeeper-3.5.2-alpha/conf),复制一份zoo\_sample.cfg重命名为zoo.cfg

3.编辑zoo.cfg，修改以下配置

# 创建数据存储目录和日志文件目录（目录需要自己创建）
    dataDir=/opt/apps/zookeeper/zookeeper-3.5.2-alpha/data
    dataLogDir=/opt/apps/zookeeper/zookeeper-3.5.2-alpha/logs
    
    #设置server地址(hostname为本服务器地址；第一个端口用于集合体中follower以侦听leader；第二个端口用于leader选举)
    server.1=172.19.76.133:2888:3888

完整配置文件如下

# 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/apps/zookeeper/zookeeper-3.5.2-alpha/data
    dataLogDir=/opt/apps/zookeeper/zookeeper-3.5.2-alpha/logs
    # the port at which the clients will connect
    clientPort=2181
    server.1=172.19.76.133:2888:3888
    # 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

4.在上一步创建的data目录下创建mydata文件，填入服务器配置后面的数字，这里为1，给服务器进行编号

5.启动ZooKeeper服务端

./zkServer.sh start

root@iZuf69wuhmgaijvje9a369Z:/opt/apps/zookeeper/zookeeper-3.5.2-alpha/bin# ./zkServer.sh start
    ZooKeeper JMX enabled by default
    Using config: /opt/apps/zookeeper/zookeeper-3.5.2-alpha/bin/../conf/zoo.cfg
    Starting zookeeper ... STARTED

注意：请勿使用sh zkServer.sh start来启动zkServer，会出现无法找到JAVA\_HOME环境变量错误  
![zk启动异常][zk]

6.查看zkServer状态

./zkServer.sh status

root@VM-0-15-ubuntu:/opt/apps/zookeeper/zookeeper-3.5.2-alpha/bin# ./zkServer.sh status
    ZooKeeper JMX enabled by default
    Using config: /opt/apps/zookeeper/zookeeper-3.5.2-alpha/bin/../conf/zoo.cfg
    Client port found: 2181. Client address: localhost.
    Mode: standalone
