PHPStudy database cannot be started, what should I do?

PHPStudy database startup failed, which may be due to the following reasons:

1. The database service is not opened

• Open PHPStudy control panel.
• Click the "Database" tab and make sure the "MySQL" service is turned on.

2. Port number conflict

• Check whether the MySQL port number is occupied by other programs.

• You can check the port number through the following command:

  • Windows: netstat -ano | findstr "3306"
  • macOS/Linux: sudo lsof -i | grep mysqld
• #If the port number is occupied, please change the MySQL port number.

3. Permission issues

• Make sure that the MySQL user has permission to start and stop the database.
• Open the PHPStudy control panel, click the "Database" tab, and then click the "Manage" button.
• In the "Permissions" tab, make sure the "GRANT" option is selected.

4. Firewall restrictions

• Check whether the firewall blocks access to the MySQL port (default 3306).
• Open the firewall settings and allow the MySQL port to pass.

5. Database corruption

• If nothing else works, the database may be corrupted.
• Try to repair the database or recreate it.

6. Service configuration error

• Check whether the configuration of the MySQL service is correct.
• Open the PHPStudy control panel, click the "Database" tab, and then click the "Configure" button.
• Make sure the "datadir" path is correct and the MySQL service is configured normally.

7. Software conflicts

• Check whether there are other software that may conflict with MySQL.
• For example, other database software or anti-virus software.
• Try temporarily disabling these software to see if that solves the problem.

If none of the above methods solve the problem, please try to reinstall PHPStudy or contact MySQL official support.
