拉取官方的镜像，（这个示例中，官方镜像也是stars最多的）：

[root@server02 ~]#  docker pull redis

查看镜像

[root@server02 ~]# docker images

[root@server02 ~]# docker run --name=redis_test -p 6379:6379 -v /data:/data -d redis:latest redis-server --appendonly yes --requirepass "gs123456"
6fb880e4763b9bea8d9b9902d2021c96e855fc1e519992768d5e56f275abfa0b
[root@server02 ~]# docker ps -a
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
6fb880e4763b redis:latest "docker-entrypoint.s…" 7 seconds ago Up 6 seconds 0.0.0.0:6379->6379/tcp redis_test
[root@server02 ~]#

命令说明：

-p 6379:6379 : 将容器的6379端口映射到主机的6379端口
-v $PWD/data:/data : 将主机中当前目录下的data挂载到容器的/data
redis-server --appendonly yes : 在容器执行redis-server启动命令，并打开redis持久化配置
--requirepass：redis密码

连接redis的几种方式：

docker exec -ti redis_test redis-cli -h localhost -p 6379
docker exec -ti redis_test redis-cli -h 127.0.0.1 -p 6379 
docker exec -ti redis_test redis-cli -h 172.17.0.3 -p 6379 

查看容器的ip：

[root@server02 ~]# docker inspect redis_test | grep IPAddress
            "SecondaryIPAddresses": null,
            "IPAddress": "172.17.0.2",
                    "IPAddress": "172.17.0.2",

使用redis镜像执行redis-cli命令连接到刚启动的容器,主机IP为172.17.0.1

[root@server02 ~]# docker exec -it redis_test redis-cli
127.0.0.1:6379> 

如果连接远程：

[root@server02 ~]# docker exec -it redis_test redis-cli -h 192.168.0.221 -p 6379 -a gs123456
