You need to install the PDO extension in Ubuntu's PHP environment, then open or add:
extension=php_pdo_mysql.so
extension=php_pdo.so
Then restart the web container

This problem is a bit troublesome, I suggest you add me for private chat on QQ, 1065890063

There is no PDO extension

Please do not add wrong tags such as java, html, etc.

Install pdo_mysql extension

Please tell me how to solve the problem. Did you not install the PDO extension? still?
