## ZooKeeper 常用命令 注：我是通过 docker-compose 安装的ZooKeeper集群。 安装方式：[docker-compose安装ZooKeeper集群](https://zysite.top/archives/zookeeper-docker-compose-install) ### 服务端 交互式进入容器，查看 bin 目录下文件： ```shell root@zoo1:/apache-zookeeper-3.6.2-bin/bin# ls -al total 72 drwxr-xr-x 2 zookeeper zookeeper 4096 Sep 4 12:43 . drwxr-xr-x 6 zookeeper zookeeper 4096 Sep 22 18:09 .. -rwxr-xr-x 1 zookeeper zookeeper 232 Sep 4 12:43 README.txt -rwxr-xr-x 1 zookeeper zookeeper 2066 Sep 4 12:43 zkCleanup.sh -rwxr-xr-x 1 zookeeper zookeeper 1158 Sep 4 12:43 zkCli.cmd -rwxr-xr-x 1 zookeeper zookeeper 1620 Sep 4 12:43 zkCli.sh -rwxr-xr-x 1 zookeeper zookeeper 1843 Sep 4 12:43 zkEnv.cmd -rwxr-xr-x 1 zookeeper zookeeper 3690 Sep 4 12:43 zkEnv.sh -rwxr-xr-x 1 zookeeper zookeeper 4559 Sep 4 12:43 zkServer-initialize.sh -rwxr-xr-x 1 zookeeper zookeeper 1286 Sep 4 12:43 zkServer.cmd -rwxr-xr-x 1 zookeeper zookeeper 11116 Sep 4 12:43 zkServer.sh -rwxr-xr-x 1 zookeeper zookeeper 988 Sep 4 12:43 zkSnapShotToolkit.cmd -rwxr-xr-x 1 zookeeper zookeeper 1377 Sep 4 12:43 zkSnapShotToolkit.sh -rwxr-xr-x 1 zookeeper zookeeper 996 Sep 4 12:43 zkTxnLogToolkit.cmd -rwxr-xr-x 1 zookeeper zookeeper 1385 Sep 4 12:43 zkTxnLogToolkit.sh ``` `zkCli`即为ZooKeeper客户端工具，`zkServer`即为服务端。（其中.sh为linux环境下、.cmd为window环境下） - 启动服务 ```shell ./zkServer.sh start ``` - 停止服务 ```shell ./zkServer.sh stop ``` - 重启服务 ```shell ./zkServer.sh restart ``` - 执行状态 ```shell ./zkServer.sh status ``` ### 客户端 - 连接服务器 ```shell ./zkCli.sh -server <ip>:<port> ``` - 创建结点 ```shell create /test "Hello ZooKeeper" ``` - 获取结点 ```shell get /test ``` 可以加上 -s 参数获取详细信息： ```shell [zk: localhost:2181(CONNECTED) 3] get /test -s Hello ZooKeeper cZxid = 0x100000006 ctime = Fri Oct 09 06:44:34 UTC 2020 mZxid = 0x100000006 mtime = Fri Oct 09 06:44:34 UTC 2020 pZxid = 0x100000006 cversion = 0 dataVersion = 0 aclVersion = 0 ephemeralOwner = 0x0 dataLength = 4 numChildren = 0 ``` - 删除结点 ```shell delete /test ``` [更多命令](https://zookeeper.apache.org/doc/current/zookeeperCLI.html)
