不能一直搜索mysqld: Can't create/write to file '/var/lib/mysql/is_writable' (Errcode: 13 - Permission denied)，一直搜索这个问题，我一直没有解决这个问题，因为该搜索Docker安装Percona的步骤的问题，从另一问题去搜索就会得到答案。其实就是设置权限的问题。

#创建容器

docker create --name percona -v /data/mysql-data:/var/lib/mysql -p 3306:3306 -e MYSQL_ROOT_PASSWORD=root percona:5.7.23

就是在cd /data 中添加权限 ；chomd -R 777 data/mysql-data/
