一、搜索redis镜像

命令：docker search <镜像名称>

[root@nightmare-01 kerwin]# docker search redis

二、拉取镜像

命令：docker pull <镜像名称>:<版本号>

[root@nightmare-01 kerwin]# docker pull redis
Using default tag: latest
latest: Pulling from library/redis
bd159e379b3b: Pull complete 
729b630784ac: Pull complete 
065c77bf222a: Pull complete 
961784053f68: Pull complete 
b42f16846808: Pull complete 
0f1fa5bb0033: Pull complete 
Digest: sha256:c95835a74c37b3a784fb55f7b2c211bd20c650d5e55dae422c3caa9c01eb39fa
Status: Downloaded newer image for redis:latest
docker.io/library/redis:latest

三、准备redis挂载配置文件

1.挂载的目的在于：以配置文件方式启动redis容器，不需要进容器内修改配置，直接在宿主机上修改配置文件也会随之修改容器内配置文件。
2.准备两个文件夹：挂载配置文件（/kerwin/install/redis/myredis01/redis.conf） 和redis数据持久化（/kerwin/install/redis/myredis01/data）

四、启动redis容器

docker run --restart=always --log-opt max-size=100m --log-opt max-file=2 -p 6379:6379 --name myredis01 -v /kerwin/install/redis/myredis01/redis.conf:/etc/redis/redis.conf -v /kerwin/install/redis/myredis01/data:/data -d redis redis-server /etc/redis/redis.conf  --appendonly yes  --requirepass wu1234

1.--restart=always 总是开机启动。
2.--log是日志方面的。
3.-p 6379:6379 将6379端口挂载出去。
4.--name 给这个容器取一个名字。
5.-v 数据卷挂载
/kerwin/install/redis/myredis01/redis.conf:/etc/redis/redis.conf 这里是将 liunx 路径下的redis.conf 和redis容器下的redis.conf 挂载在一起，
/kerwin/install/redis/myredis01/data:/data 这个同上。
6.-d redis 表示后台启动redis。
7.redis-server /etc/redis/redis.conf 以配置文件启动redis，加载容器内的conf文件。
8.--appendonly yes 开启redis 持久化。
9.--requirepass wu1234 设置密码 。

五、测试

1.通过docker ps -a 指令查看启动状态

[root@nightmare-01 myredis01]# docker ps -a | grep myredis
466a946ca3ae   redis      "docker-entrypoint.s…"   About a minute ago   Up About a minute   0.0.0.0:6379->6379/tcp, :::6379->6379/tcp  myredis01

2.查看容器日志

docker logs --since 30m 466a946ca3ae

image.png

3.容器内获取key，并设置密码。

[root@nightmare-01 ~]# docker exec -it 466a946ca3ae redis-cli
127.0.0.1:6379> get a
(error) NOAUTH Authentication required.
127.0.0.1:6379> auth wu1234
OK
127.0.0.1:6379> get a
(nil)
127.0.0.1:6379> config get requirepass
1) "requirepass"
2) "wu1234"
127.0.0.1:6379>
