安装
1.拉取镜像
docker pull zookeeper
2.启动单实例
- 执行命令
#--name 为容器指定名称
#-d 指定为后台运行
#--restart 容器的重启策略
# no - 默认值
# on-failure[:max-retries] 只在容器以非0状态码退出时重启
# always 一直直尝试 不管是什么状态码
docker run --name some-zookeeper --restart no -d zookeeper
- 查看日志
e24-6:~ dailong$ docker run --name some-zookeeper --restart no -d zookeeper

3.启动多实例集群,利用docker-compose
e24-6:docker dailong$ cat docker-compose.yml
version: '3.1'
services:
zoo1:
image: zookeeper
restart: always
hostname: zoo1
ports:
- 2181:2181
environment:
ZOO_MY_ID: 1
ZOO_SERVERS: server.1=0.0.0.0:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=zoo3:2888:3888;2181
zoo2:
image: zookeeper
restart: always
hostname: zoo2
ports:
- 2182:2181
environment:
ZOO_MY_ID: 2
ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=0.0.0.0:2888:3888;2181 server.3=zoo3:2888:3888;2181
zoo3:
image: zookeeper
restart: always
hostname: zoo3
ports:
- 2183:2181
environment:
ZOO_MY_ID: 3
ZOO_SERVERS: server.1=zoo1:2888:3888;2181 server.2=zoo2:2888:3888;2181 server.3=0.0.0.0:2888:3888;2181
- 到yml文件目录,运行命令即可:
e24-6:docker dailong$ ls
docker-compose.yml
e24-6:docker dailong$ docker-compose up -d

我之前也没接触过,只听说过了解,使用后面补
