0x00 事由
日志系统开发完成了，服务已经部署到服务器上，也该把本地数据库上传上去了，于是就在docker上面安装了mysql:5.7，但是在开发环境中mysql是不区分大小写的，而docker上面的确实默认区分大小写，所以需要关闭大小写敏感这个选项。
0x01 步骤
首先进入容器内部
docker exec -it 容器ID /bin/bash
cd /etc/mysql/mysql.conf.d
vi mysqld.cnf
发现没有vi，那就装一下吧
apt-get update
apt-get install vim
vi mysqld.cnf
在结尾追加一行

wq保存后，ctrl d退出容器，重启容器即可生效
