1.3、更名

cd /usr/local/zookeeper/conf
    cp zoo_sample.cfg zoo.cfg

1.4、创建文件

mkdir -p  /usr/local/datas/zookeeper
    mkdir -p  /usr/local/logs/zookeeper

1.5、修改配置文件

vim zoo.cfg
    #数据文件
    dataDir=/usr/local/datas/zookeeper
    #日志文件
    dataLogDir=/usr/local/logs/zookeeper
    #暴露端口
    clientPort=2181

1.6、开启

cd /usr/local/zookeeper/bin
    ./zkServer.sh start

## 2、常用命令 ##

#连接客户端：
    cd  /usr/local/zookeeper/bin
    ./zkCli.sh

#语法 create，s代表顺序，e代表临时，如果不添加-s或-e创建的是持久节点，acl是权限控制
    create [-s] [-e] path data acl
    #创建节点
    create /node1 node1
    #创建临时节点
    create -e /node2 node2
    #创建有序持久节点
    create /list1 list
    create -s  /list1/list node1
    create -s  /list1/list node1
    create -s  /list1/list node1
    #创建临时有序节点
    create /list2 list
    create -s  -e /list2/list node1
    create -s  -e /list2/list node1
    create -s  -e /list2/list node1

2.2、查看

#命令 查看path目录下的节点
    ls path
    #命令 查看某个节点的信息
    get path

#退出客户端
    quit
    #重新连接
    ./zkCli.sh
    #查看节点，临时节点node2消失了
    ls /
    #查看list2下面的顺序临时节点
    ls /list2

2.3、更新

#更新命令
    set path data [version]
    #更新
    set /node1 tuoxiaoxiao

2.4、删除

#删除一个节点，该节点下没有子节点
    delete path [version]
    #测试
    delete /node1
    
    #删除一个节点包含下面的子节点
    rmr path
    #测试
    rmr /list1
