What should I do if Laravel connects to MySQL database error 'Driver not found'?

Laravel database connection error: missing driver causes connection failure

In Laravel development, the "can not find driver" error message is a common problem, which can occur even if the database is configured correctly and the migration is completed. This article provides solutions to such problems under Laravel 5.8.38, PHP 7.4.3, and MySQL 8.0.21.

Problem description: The developer has verified that the MySQL database is configured correctly and the data migration has been completed, but he still encountered the "can not find driver" error, which caused the data to be queryed from my_admin table.

Known information: The php -m command shows that mysqli and pdo_mysql modules are installed, both of which are related to the MySQL database connection. However, this does not guarantee that these modules are loaded correctly in the current running environment. php -m lists only compiled modules, not currently enabled.

Solution:

The key is to confirm that the MySQL driver is enabled correctly. It is recommended to use php -i | grep mysqlnd command for troubleshooting. mysqlnd (MySQL Native Driver) is a MySQL driver for PHP. If the command does not return any information related to mysqlnd , it means that the driver is not enabled.

Workaround: Check the PHP configuration file (usually php.ini ) and make sure that extension=mysqlnd or extension=mysqli (depending on your configuration) lines exist and are not commented. After saving the changes, restart the PHP service to make the configuration take effect. This will ensure that Laravel can find and use the correct MySQL driver.

Note: The advice provided in this article is not the only way to solve the “can not find driver” problem, but it is the most direct and effective way to solve such problems. Other environment configuration issues can also cause this error, but it is fundamentally resolved only if you make sure that the MySQL driver is enabled correctly.
