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.

Navicat's solution to the database cannot be connected
Apr 08, 2025 pm 11:12 PM
The following steps can be used to resolve the problem that Navicat cannot connect to the database: Check the server connection, make sure the server is running, address and port correctly, and the firewall allows connections. Verify the login information and confirm that the user name, password and permissions are correct. Check network connections and troubleshoot network problems such as router or firewall failures. Disable SSL connections, which may not be supported by some servers. Check the database version to make sure the Navicat version is compatible with the target database. Adjust the connection timeout, and for remote or slower connections, increase the connection timeout timeout. Other workarounds, if the above steps are not working, you can try restarting the software, using a different connection driver, or consulting the database administrator or official Navicat support.
