1.9.2.2. 启动一个 Redis 实例

# docker run --name my-redis -d redis
10207174e18f61290f9c869e6437fa787e459e07b076b82cedf800a8c37c515d

查看启动情况

		# docker ps 
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS               NAMES
10207174e18f        redis               "docker-entrypoint..."   8 minutes ago       Up 8 minutes        6379/tcp            my-redis

1.9.2.3. 进入 Redis

		# docker run -it --link my-redis:redis --rm redis redis-cli -h redis -p 6379
redis:6379> set name neo
OK
redis:6379> get name
"neo"
redis:6379> exit

1.9.2.4. 启动一个 Redis 实例并映射 6379 端口

		# docker rm my-redis
my-redis

# docker stop my-redis
my-redis

# docker run --name my-redis -d -p 6379:6379 redis
10207174e18f61290f9c869e6437fa787e459e07b076b82cedf800a8c37c515d

# docker ps -a                                    
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                    NAMES
1c4540d8617f        redis               "docker-entrypoint..."   2 seconds ago       Up 1 second         0.0.0.0:6379->6379/tcp   my-redis

检查端口

		# ss -lnt | grep 6379
LISTEN     0      128         :::6379                    :::*

1.9.2.5. 维护容器

使用下面命令进入容器维护 Redis

		# docker exec -it my-redis /bin/bash
root@1c4540d8617f:/data#
