不能一直搜尋mysqld: Can't create/write to file '/var/lib/mysql/is_writable' (Errcode: 13 - Permission denied)，一直搜尋這個問題，我一直沒有解決這個問題，因為該搜尋Docker安裝Percona的步驟的問題，從另一問題去搜尋就會得到答案。其實就是設定權限的問題。

#建立容器

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 中添權重限 ；chomd -R 777 data/mysql-data/
