修改mysql的配置文件 设置字符编码等
vim /mydata/mysql/conf/my.cnf
[client]
default-character-set=utf8
[mysql]
default-character-set=utf8
[mysqld]
init_connect='SET collation_connection = utf8_unicode_ci'

重启mysql docker restart mysql
安装redis
拉取镜像
docker pull redis
启动redis
创建文件夹
mkdir -p /mydata/redis/conf
touch /mydata/redis/conf/redis.conf
docker run -p 6379:6379 --name redi -v /mydata/redis/data:/data\
-v /mydata/redis/conf/redis.conf:/etc/redis/redis.conf\
-d redis redis-server /etc/redis/redis.conf --privileged=true
注意，最新版的命令不同，容器内的conf文件的位置变为了/usr/local/etc/redis/redis.conf
mkdir -p /mydata/redis/conf
touch /mydata/redis/conf/redis.con
进入到redis控制台
docker exec -it redis redis-cli
开启redis持久化
