How to update mysql version in xampp (error with innodb_additional_mem_pool_size)

Question

I\'m trying to upgrade mysql in xamp. I\'m using laravel which requires mariaDB v10.2.2. So I downloaded the latest

Answer 1

To Upgrade MySql included in XAMPP (I did it on a Windows system):

1. Rename your Mysql directory to some other name.
2. Download the .msi file from the MariaDB link https://downloads.mariadb.org/.
3. Run .msi. Change the install directory to your Mysql location under XAMPP.
4. After completion, copy the old my.ini from the original mysql/bin directory to your new mysql/bin directory.
5. You should be able to start Mysql from the XAMPP control panel.

I found the solution here http://www.mynotebucket.com/update-mysql-under-xmpp/

Answer 2

Simply remove this line from my.ini:

    innodb_additional_mem_pool_size = 2M

It was "deprecated in MySQL 5.6.3, are removed in MySQL 5.7.4."

(If my notes are correct, it has been "unused" since 4.1.0!)

Answer 3

What I did and saved my life:

1. Rename xampp/mysql/data to xampp/mysql/anyname_data (or any name of your choice)

2. Create a new folder and name it > data in xampp/mysql

3. Copy all your xampp/mysql/backup files and folder to newly created xampp/mysql/data folder

4. Now which previous database you want to work with copy that folder from xampp/mysql/anyname_data to newly created xampp/mysql/data folder

5. Restart Xampp with or without "run as administrator"

Amazingly! your database is intact in phpmyadmin.

Thank you very much!
