# 安装redis

**1. 前提是Docker已经安装好了**

**2.拉取Redis镜像**

```shell
docker pull redis
```

**3.启动**

```shell
docker run --name redis -p 6378:6379 -d --restart=always redis redis-server --appendonly yes --requirepass "123456"
```

> 参数讲解
>
> `--name`为容器取一个唯一的名字
>
> `-p`端口映射，把宿主机的端口映射到容器内的端口
>
> `--restar=always`随容器启动而启动
>
> `redis-server --appendonly yes`在容器里执行`redis-server`命令，打开redis持久化
>
> `--requirepass`密码

**4.连接**

```
docker ps 查看CONTAINER ID
docker exec -it 0047b8680fc2 redis-cli
```
