# 安装Zookeeper #

Zookeeper下载地址：[http://zookeeper.apache.org/releases.html][http_zookeeper.apache.org_releases.html]，我使用的版本是：zookeeper-3.4.13

将下载后的 zookeeper解压，在 conf/下，复制zoo\_sample.cfg重命名为 zoo.cfg 文件

# 常用配置 #

tickTime=2000
    dataDir=/opt/zookeeper-3.4.13/my_data/
    clientPort=3181

**tickTime 心跳时间**

**dataDir  数据目录**

**clientPort 客户端连接端口（我更改了端口3181，默认2181）**

其他参数

# 启动Zookeeper #

如果是windows，则使用.cmd文件

./bin/zkServer.sh start

zkCli.xx  \---> 客户端命令程序

zkEnv.xx  \---> 环境设置命令程序

zkServer.xx  ---> 服务器命令程序

# 客户端连接 #

客户端连接 Zookeeper服务器

./bin/zkCli.sh -server 127.0.0.1:3181

这样就表示连接成功了

# 常用命令 #

输入help

[zk: 127.0.0.1:3181(CONNECTED) 0] help
    ZooKeeper -server host:port cmd args
    	stat path [watch]
    	set path data [version]
    	ls path [watch]
    	delquota [-n|-b] path
    	ls2 path [watch]
    	setAcl path acl
    	setquota -n|-b val path
    	history 
    	redo cmdno
    	printwatches on|off
    	delete path [version]
    	sync path
    	listquota path
    	rmr path
    	get path [watch]
    	create [-s] [-e] path data acl
    	addauth scheme auth
    	quit 
    	getAcl path
    	close 
    	connect host:port

**使用案例：**

添加路径节点 / 设置值 / 获得值 / 删除路径节点

[zk: 127.0.0.1:3181(CONNECTED) 2] create /name minbo
    Created /name
    [zk: 127.0.0.1:3181(CONNECTED) 3] get /name
    minbo
    cZxid = 0x92e
    ctime = Tue Jun 25 11:40:41 CST 2019
    mZxid = 0x92e
    mtime = Tue Jun 25 11:40:41 CST 2019
    pZxid = 0x92e
    cversion = 0
    dataVersion = 0
    aclVersion = 0
    ephemeralOwner = 0x0
    dataLength = 5
    numChildren = 0
    [zk: 127.0.0.1:3181(CONNECTED) 4] delete /name
    [zk: 127.0.0.1:3181(CONNECTED) 5] get /name   
    Node does not exist: /name
