Repairing Corrupt MySQL 'user' Table in XAMPP

The error message "Table 'mysql.user' is marked as crashed and should be repaired" indicates a corrupt MySQL 'user' table in XAMPP. Here's a step-by-step guide to resolve this issue:

1. Remove 'skip-grant-tables' Setting (If Added):
If you had previously added 'skip-grant-tables' to your 'my.ini' file, remove this line after restarting XAMPP.

2. Repair 'user' Table:

• Start XAMPP and open phpMyAdmin.
• In the left panel, select the 'mysql' database.
• In the right panel, right-click on the 'user' table and choose 'Repair Table'.

3. Recreate 'user' Table if Repair Fails:
If the repair fails, drop the 'user' table and recreate it using the following files from the distribution backup:

• C:\xampp\mysql\backup\mysql\user.frm
• C:\xampp\mysql\backup\mysql\user.MYD
• C:\xampp\mysql\backup\mysql\user.MYI

Copy these files to:

• C:\xampp\mysql\data\mysql\

4. Repair 'db' Table (Optional):
In some cases, repairing the 'user' table may also require repairing the 'db' table. Follow step 2 to repair the 'db' table if necessary.

5. Restart XAMPP and Manage Users:
Restart XAMPP and verify that the 'mysql.user' table has been restored successfully. You can now add, remove, or edit users as needed.

Note:
To prevent future table corruption, ensure that MySQL is running with sufficient privileges and resources. Regular backups are also crucial for data recovery in case of similar issues.
