一切福田，不離方寸，從心而覓，感無不通。

Docker 部署 zookeeper

1.单节点安装

官方镜像：https://registry.hub.docker.com/_/zookeeper/tags

docker pull zookeeper:3.6.4
# 创建卷
docker volume create zookeeper ; docker volume ls
docker run -d \
-e TZ="Asia/Shanghai" \
-p 2181:2181 \
-v zookeeper:/data \
--name zookeeper \
--restart always zookeeper:3.6.4
docker run -it --rm --link zookeeper:zookeeper zookeeper:3.6.4 zkCli.sh -server zookeeper

2.集群安装

2.1.docker-compose命令安装

Github：https://github.com/docker/compose/tree/v2.17.3

curl -L "https://github.com/docker/compose/releases/download/v2.17.3/docker-compose-linux-x86_64" -o /usr/local/bin/docker-compose
chmod +x /usr/local/bin/docker-compose
docker-compose --version

  • ZOO_MY_ID：zk服务的ID，取值为1-255之间的整数。

  • ZOO_SERVERS：表示zk集群的主机列表

注：这里3.5之后，ZOO_SERVERS后面要加上;2181，客户端端口。
