CentOS 7 中使用 Docker 安装 ZooKeeper

docker pull zookeeper:3.4.14

/root/zookeeper-test/conf
/root/zookeeper-test/data
/root/zookeeper-test/datalog

docker run -d --name zookeeper-test \
--restart always \                        # docker服务启动时, 默认启动zookeeper-test容器
-p 2181:2181 -p 2888:2888 -p 3888:3888 \
-v /root/zookeeper-test/conf:/conf \
-v /root/zookeeper-test/data:/data \
-v /root/zookeeper-test/datalog:/datalog \
zookeeper:3.4.14

# 使用zookeeper的四字命令, 验证zookeeper是否启动成功
echo ruok | nc localhost 2181

# 进入一个容器的命令行
docker exec -it zookeeper-test /bin/bash

# 到 zookeeper/bin下, 运行zookeeper客户端
./zkCli.sh

# 创建一个节点
create /test test

# 获取节点
get /test
