PDOException in Connector.php line 119: could not find driver

I installed Laravel 5.3 on CentOS 6.8. I updated php to 5.6.27, installed mysql-pdo, php-pdo.

In phpinfo(): PDO drivers: sqllite SQLite Library 3.6.20

But when I get data from DTB, I still get error:

PDOException in Connector.php line 119: could not find driver.

I did some search online, and one of solutions is:

uncommented ;extension=php_pdo_mysql.dll,

but I can't find it in my ect/php.ini file. when I add it manually, I got the message "

php startup unable to load dynamic library php_pdo_mysql.dll ...

" in php artisan migrate, and the error display in web is still the same. Here's my env file:
