参考资料
基础使用
1. 获取Redis镜像
docker pull redis

2. 检查是否拉取成功
[root@VM-0-10-centos project]# docker images |grep redis
docker.io/redis latest 739b59b96069 12 days ago 105 MB

3. 创建Redis容器并启动
sudo docker run -itd --name redis1 -p 6390:6379 -v /home/project/mydata/redis/data:/data --restart always redis --appendonly yes --requirepass "123456"
[root@VM-0-10-centos project]# docker exec -it redis1 bash
root@199f32c349fb:/data#
root@199f32c349fb:/data#
root@199f32c349fb:/data# redis-cli
127.0.0.1:6379> get name
(error) NOAUTH Authentication required.
127.0.0.1:6379> auth 123456
OK
127.0.0.1:6379> get name
(nil)
127.0.0.1:6379>

详细说明：
-d -> 以守护进程的方式启动容器
-p 6390:6379 -> 绑定宿主机端口，6390宿主机端口，6379 容器端口
--name redis1 -> 指定容器名称
--restart always -> 开机启动
--privileged=true -> 提升容器内权限
--requirepass -> 设置登录密码
-v /home/project/mydata/redis/data:/data -> 映射数据目录
--appendonly yes -> 开启数据持久化

以文件启动：
[root@VM-0-10-centos project]# docker run -itd --name redis -p 6390:6379 --restart unless-stopped -v /home/project/mydata/redis/data:/data -v /home/project/mydata/redis/conf/redis.conf:/etc/redis/redis.conf -d redis redis-server /etc/redis/redis.conf

docker-compose方式启动
.
|-- build_redis.sh -- 构建脚本
|-- data
| `-- 6379.log
|-- docker-compose.yml
|-- environment -- 环境信息
| |-- conf
| | |-- redis-6379.conf
| | |-- redis.conf
| | `-- redis-simple.conf
| |-- Dockerfile
| `-- redis.env
`-- practice-docker-redis.md

实践
[root@VM-0-10-centos Redis]# ./build_redis.sh
[root@VM-0-10-centos Redis]# docker ps -a

解决方法：
1:命令行模式下，auth输入
root@b1298edf0d30:/data# ./redis-cli
127.0.0.1:6379> auth 123456
OK
127.0.0.1:6379> keys *
1) "name"
127.0.0.1:6379> set num 44444
OK
127.0.0.1:6379>

root@b1298edf0d30:/data#
redis-cli -h 127.0.0.1 -p 6379 -a 123456
