2、解决方案

（1）新建 conf.d文件夹 和 mysql.conf.d文件夹
		drwxr-xr-x. 2 root root   6 10月 27 23:05 conf.d
		drwxr-xr-x. 2 root root   6 10月 27 23:07 mysql.conf.d
		-rw-r--r--. 1 root root 283 10月 27 22:33 my.cnf


（2）运行以下命令
docker run \
--name mysql \
--privileged=true \
-p 3306:3306 \
-v /mydata/mysql/log:/var/log/mysql \
-v /mydata/mysql/data:/var/lib/mysql \
-v /mydata/mysql/conf:/etc/mysql \
-e MYSQL_ROOT_PASSWORD=root \
-d mysql:5.7
