XAMPP - Replacing MariaDB with MySQL

As of XAMPP 5.5.30 and 5.6.14, XAMPP ships MariaDB instead of MySQL. MariaDB is not 100% compatible with MySQL and can be replaced with the "orginal" MySQL server.

Requirements

• Windows
• XAMPP for Windows

Backup

• Backup the old database into a sql dump file
• Stop the MariaDB service
• Rename the folder: c:\xampp\mysql to c:\xampp\mariadb

Installation

• Download MySQL Community Server: https://dev.mysql.com/downloads/mysql/
• Goto: Other Downloads > ZIP Archive 5.7.21 (mysql-5.7.21-win32.zip) > No thanks, just start my download.
• Create a new and empty folder: c:\xampp\mysql
• Extract mysql-5.7.21-win32.zip to: c:\xampp\mysql
• Create a new file: c:\xampp\mysql\bin\my.ini and copy this content:

[mysqld]
# Set basedir to your installation path
basedir=c:/xampp/mysql

# Set datadir to the location of your data directory
datadir=c:/xampp/mysql/data

# Default: 128 MB
# New: 1024 MB
innodb_buffer_pool_size = 1024M

Initializing the data directory

• Copy the old data directory from c:\xampp\mariadb\data to c:\xampp\mysql\data

• Start the MySQL server. You can use the XAMPP Control Panel (MySQL > Start) to start the MySQL service.

• Repair all corrupted tables in the c:\xampp\mysql\data directory. Press ENTER if your password is empty.

cd c:\xampp\mysql\bin

mysqlcheck.exe -u root -p --auto-repair --all-databases

Update structure to latest version:

mysql_upgrade.exe -u root -p

Check the tables for errors:

mysqlcheck.exe -u root -p --check --all-databases
