镜像
image: redis
容器名
container_name: my_redis
centos中的selinux会报没有权限的问题，给docker给个特殊权限
privileged: true
启动redis的参数
command: redis-server --requirepass 123456 --appendonly yes
端口映射
ports:
- “6379:6379”
将宿主机目录挂载到容器中的文件夹中
volumes:
- ./redis/data:/data
其中zk启动的时候配置ZOO_PORT: 2181没有生效，需要手动配置zk配置文件
cat zookeeper/conf/zoo.cfg

dataLogDir=/datalog

由于覆盖了/conf下面的文件，故需要把log4j文件复制出来

启动的时候会遇到docker防火墙的问题
解决： 修改/etc/sysconfig/docker里的OPTIONS增加–iptables=false，重启docker服务，再启动redis，顺利开启。
常用命令：
docker-compose up -d 创建并且启动容器
docker-compose stop 停止所有服务
docker-compose rm 删除所有容器
docker-compose start(stop) 后面加容器名可开始或者停止某个服务（跟docker启停没有什么区别）
