3. 拉取镜象

[root@master ~]#  docker pull redis
Using default tag: latest
latest: Pulling from library/redis

Status: Downloaded newer image for redis:latest

[root@master ~]# docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE

4. 创建容器

# 创建镜像
[root@master ~]# docker run -p 6379:6379 -d redis:latest redis-server
0ffdfb70bbfb6cf7e13d213a3f34ddd934990f102262da78784067cf790913c2
# 数据挂载到容器
[root@master ~]# docker run -p 6379:6379 -v $PWD/data:/data  -d redis:latest redis-server --appendonly yes
#  查看容器网络
[root@master ~]# docker inspect 0ffdfb70bbfb  | grep IPAddress
            "SecondaryIPAddresses": null,
            "IPAddress": "172.17.0.3",
                    "IPAddress": "172.17.0.3",

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

5. 连接redis的几种方式

[root@master ~]# docker exec -ti 0ffdfb70bbfb  redis-cli
127.0.0.1:6379> 
[root@master ~]# docker exec -ti 0ffdfb70bbfb   redis-cli -h localhost -p 6379 
[root@master ~]# docker exec -ti 0ffdfb70bbfb  redis-cli -h 127.0.0.1 -p 6379 
[root@master ~]# docker exec -ti 0ffdfb70bbfb  redis-cli -h 172.17.0.3 -p 6379 

注意，这个是容器运行的ip，可通过 docker inspect redis_s | grep IPAddress 查看

二、客户端连接
