zookeeper安装运行(docker)

拉取镜像
docker pull zookeeper:latest

获取镜像基本信息
docker inspect zookeeper

mkdir /opt/zookeeper -p

vim /opt/zookeeper/Dockerfile

ZOO_SERVERS中的zookeeper为容器名

启动

cd /opt/zookeeper
docker-compose build
docker-compose up -d --force-recreate
docker-compose down
docker-compose restart

查看日志

docker logs --tail="500" zookeeper

备份配置文件

docker cp zookeeper:/conf/zoo.cfg /opt/zookeeper/conf/zoo_bak.cfg

进入容器

docker exec -it zookeeper /bin/bash

检查容器状态

docker exec -it zookeeper1 /bin/bash ./bin/zkServer.sh status
