一、找到一个合适的docker的redis的版本

可以去docker hub中去找一下

Docker Hub

二、使用docker安装redis

sudo docker pull redis

安装好之后使用docker images即可查看

truedei@truedei:~$ 
truedei@truedei:~$ sudo docker images
REPOSITORY          TAG                 IMAGE ID            CREATED             SIZE
redis               latest              987b78fc9e38        10 days ago         104MB
httpd               latest              a8a9cbaadb0c        2 weeks ago         166MB
fjudith/draw.io     latest              7b136fc80d31        3 weeks ago         683MB
mysql               5.7.29              f5829c0eee9e        5 weeks ago         455MB

truedei@truedei:~$

三、准备redis的配置文件

因为需要redis的配置文件，这里最好还是去redis的官方去下载一个redis使用里面的配置文件即可

redis中文官方网站：redis 6.0.6 下载 -- Redis中国用户组（CRUG）

下载后解压出来：

这个redis.conf文件就是咱们需要的，为了保险，还是拷贝一下，做个备份。

四、配置redis.conf配置文件

修改redis.conf配置文件： 主要配置的如下：

五、创建本地与docker映射的目录，即本地存放的位置

创建本地存放redis的位置;

truedei@truedei:redis-5.0.5$ sudo mkdir /data/redis
truedei@truedei:redis-5.0.5$ sudo mkdir /data/redis/data

把配置文件拷贝到刚才创建好的文件里

truedei@truedei:redis-5.0.5$ sudo cp -p redis.conf /data/redis/
truedei@truedei:redis-5.0.5$

六、启动docker redis

启动：

truedei@truedei:~$ sudo docker run -p 6379:6379 --name redis -v /data/redis/redis.conf:/etc/redis/redis.conf  -v /data/redis/data:/data -d redis redis-server /etc/redis/redis.conf --appendonly yes

参数解释：

七、查看是否启动成功

查看是否成功启动：sudo docker ps

truedei@truedei:~$ sudo docker ps
CONTAINER ID        IMAGE               COMMAND                  CREATED             STATUS              PORTS                               NAMES
85cb7d83a2ff        redis               "docker-entrypoint.s…"   7 minutes ago       Up 7 minutes        0.0.0.0:6379->6379/tcp              redis
0a122a08125f        mysql:5.7.29        "docker-entrypoint.s…"   5 weeks ago         Up About an hour    0.0.0.0:3306->3306/tcp, 33060/tcp   mysql57
truedei@truedei:~$

可以查看一下日志：sudo docker logs redis

truedei@truedei:~$ sudo docker logs redis
