zookeeper介绍及mac环境搭建（5）
zookeeper 基本介绍
zookeeper是Apacahe Hadoop的子项目，是一个树型的目录服务，支持变更推送，适合作为Dubbo服务的注册中心，工业强度高，可用于生产环境，并推荐使用
zookeeper环境搭建(mac)
此地址 下载zookeeper-3.4.10.tar.gz
MacOS:10.13.1
zookeeper-3.4.13- 下载后通过命令行进入压缩包所在的目录并执行解压命令
tar -zxvf zookeeper-3.4.10.tar.gz // 解压- 进入conf目录下，修改默认配置文件名称，将zoo_sample.cfg 修改为zoo.cfg
cd zookeeper-3.4.10/conf // 切换目录
mv zoo_sample.cfg zoo.cfg // 修改名称3.打开文件zoo.cfg
dataDir：临时数据存储位置 clientPort：zookeeper的端口号
- 通过命令切换目录到zookeeper的目录下，启动Server
cd zookeeper-3.4.10/bin // 切换目录
./zkServer.sh start // 启动服务
ZooKeeper JMX enabled by default
Using config: zookeeper-3.4.10/bin/../conf/zoo.cfg
Starting zookeeper ... STARTED- cli连接
zookeeper启动后，重新打开新的命令行窗口切换目录到zookeeper的目录下，启动cli，通过cli连接zookeeper服务器
cd zookeeper-3.4.10/bin //切换到 bin目录
./zkCli.sh -server 127.0.0.1:2181- 使用zkCli.cmd测试
ls /:列出zookeeper根下保存的所有节点 create -e/aaa 123:创建一个aaa节点，值为123 get /aaa:获取/aaa节点的值
./zkCli.sh -server 127.0.0.1:2181
[zk: 127.0.0.1:2181(CONNECTED) 0] help //输入help命令
