docker下载zookeeper镜像

docker pull zookeeper

docker启动zookeeper

docker run --name uwo-zookeeper -p 2181:2181 -p 2888:2888 -p 3888:3888 -d zookeeper:latest

写配置文件zoo.cfg解决问题（Will not attempt to authenticate using SASL (unknown error)）

tickTime=2000
dataDir=/opt/zookeeper/data
clientPort=2181
initLimit=5
syncLimit=2

docker重新启动

docker run --name zookeeper -p 2181:2181 -p 2888:2888 -p 3888:3888 --net host -v ~/PROJECTS/zookeeper/zoo.cfg:/opt/zookeeper/conf/zoo.cfg --restart=always -d zookeeper:latest
