2. 启动

docker-compose up -d

3. 查看状态

docker exec -t zoo1 zkServer.sh status

4. 问题处理

CentOS下 docker 安装的zookeeper，配置了三个zookeeper主机，docker up 后进zookeeper里面去看，status后发现集群跑不起来，报错：

ZooKeeper JMX enabled by default
Using config: /conf/zoo.cfg
Client port not found in static config file. Looking in dynamic config file.
grep: : No such file or directory
Client port not found. Terminating.

原因是版本的问题，用docker搭建zookeeper集群的时候不要用最新的发行版，修改zookeeper版本是 3.4.14即可。
