2. 拉取官方的镜像，要最新版
命令：docker pull redis:latest
[root@localhost docker]# docker pull redis:latest latest: Pulling from library/redis bc51dd8edc1b: Pull complete 37d80eb324ee: Pull complete 392b7748dfaf: Pull complete 48df82c3534d: Pull complete 2ec2bb0b4b0e: Pull complete 1302bce0b2cb: Pull complete Digest: sha256:7b84b346c01e5a8d204a5bb30d4521bcc3a8535bbf90c660b8595fad248eae82 Status: Downloaded newer image for redis:latest docker.io/library/redis:latest
3. 等待下载完成后，我们就可以在本地镜像列表里查到REPOSITORY为redis，版本为latest的镜像
[root@192 docker]# docker images
REPOSITORY TAG IMAGE ID CREATED SIZE
redis latest 44d36d2c2374 6 days ago 98.2MB
4. 运行镜像
命令：docker run -itd --name zh-redis -p 6379:6379 redis
[root@192 docker]# docker run -itd --name zh-redis -p 6379:6379 redis
f7ac74b4928e7c06c55ae90d2ff2cbb79875a70ffbb735896643f31e74aeacdd
命令说明：
--name : 镜像的名称
-p 3306:3306：将容器的 3306 端口映射到主机的 3306 端口。
5. 查看容器启动情况
[root@192 docker]# docker ps
CONTAINER ID IMAGE COMMAND CREATED STATUS PORTS NAMES
f7ac74b4928e redis "docker-entrypoint.s…" 12 seconds ago Up 11 seconds 0.0.0.0:6379->6379/tcp zh-redis
6. 进入容器并操作Redis
[root@192 docker]# docker exec -it zh-redis /bin/bash root@f7ac74b4928e:/data# redis-cli 127.0.0.1:6379> set test 1 OK
