# Ubuntu 18 下安装zookeeper #

##### 下载zookeeper的压缩包， #####

下载地址： [http://apache.fayea.com/zookeeper/][http_apache.fayea.com_zookeeper]  
1. 下载完成后，解压安装包，解压到/home/wsk1103/software/zookeeper目录下  
tar zxvf zookeeper-3.4.12.tar.gz -C /home/wsk1103/software/zookeeper  
2. 拷贝zookeeper/conf/目录下的zoo\_sample.cfg，重新命名为zoo.cfg.  
3. 编辑该配置文件，gedit zoo.cfg 修改为

# The number of milliseconds of each tick
    # 心跳间隔，毫秒
    tickTime=2000
    # The number of ticks that the initial
    # synchronization phase can take
    # 配置zookeeper接受客户端初始化连接时最长能忍受多少个时间心跳间隔。
    initLimit=10
    # The number of ticks that can pass between
    # sending a request and getting an acknowledgement
    # 这个配置项标识 Leader 与 Follower 之间发送消息，请求和应答时间长度，最长不能超过多少个 tickTime 的时间长度。
    syncLimit=5
    # the directory where the snapshot is stored.
    # do not use /tmp for storage, /tmp here is just
    # example sakes.
    # 数据存放的位置
    dataDir=/home/wsk1103/sofrware/zookeeper/zookeeperData
    #日志存放的位置
    dataLogDir=/home/wsk1103/sofrware/zookeeper/zookeeperLog
    # the port at which the clients will connect
    # 服务器客户端的接口
    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
    
    # 2888,3888 are election port
    # 2888端口是zookeeper服务之间的通讯的端口，3888是zookeeper与其他应用程序通讯的端口。
    server.1=localhost:2888:3888

重点是中间添加了

dataDir=/home/wsk1103/sofrware/zookeeper/zookeeperData
    dataLogDir=/home/wsk1103/sofrware/zookeeper/zookeeperLog

结尾添加了

server.1=localhost:2888:3888

1.  根据中间添加的文件路径，创建相应的文件夹，并在zookeeperData目录下创建新的文件-myid，里面的内容为1，  
    1表示当前的zookeeper定义为第一台服务器，  
    新建文件命令：touch myid
2.  启动zookeeper服务器，进入zookeeper/bin目录，执行 ./zkServer.sh start 命令。就可以启动服务器。
3.  检验服务器命令, ./zkCli.sh -server localhost:2181。可以看到控制台的输出没有报错表示以及启动成功。
4.  停止服务器命令，./zkServer.sh stop
