How Can I Restore a MySQL Database from Its Physical .frm, .MYD, and .MYI Files?

Restoring MySQL Database from Physical Files

In certain scenarios, you may encounter a situation where the MySQL database needs to be restored from its physical files. These physical files typically include:

• .frm (table definition)
• .MYD (data storage)
• .MYI (index storage)

Restoring Process

To restore a MySQL database from physical files:

1. Understand the File Structure:

• A MyISAM table consists of three files: FRM, MYD, and MYI.
• Each table has its own set of these files, located within the database folder (e.g., /var/lib/mysql/ in Linux).

2. Copy the Physical Files:

• While the MySQL server is down, copy the physical files (FRM, MYD, MYI) from their source location to the destination database folder (where the database is to be restored).

3. Start the MySQL Server:

• Once the files are copied, start the MySQL server.

By following these steps, you should successfully restore the MySQL database from its physical files.
