I solved similar MySQL error & I think this answer will help you to fix the same type of MySQL database error.

Solution:

• Go to the “data” directory in the mysql database.
• I installed XAMPP on D: drive on my computer & the mysql “data” directory location of my computer was “D:\xampp\mysql\data\”. You may have different location.

Take Backup of MySQL “data” Folder

• First of all you should create a backup of the “data” folder using any compression software.

• Give a name like “data_backup.zip” or any type of compression you wish.

• I used winrar compression software to compress & backup mysql “data” folder.

Rename the “data” folder

• Rename the “data” folder to “data-oldfiles”. This is very important to rename the data directory to any new directory name.

Create a new “data” folder

• Create a new folder and give the folder name as “data“
• To solve the problem we need to create a new “data” directory in the mysql database.

Copy content from “backup” folder

• Go to the “backup” folder and copy all files.
• Paste the files from backup folder to data folder
• Now start the MySQL database from XAMPP.
• Your MySQL database will start properly without showing any error.

Transfer all MySQL projects Database, Data file & Log files

• If you have many database which was used for various projects, then you have to transfer all database from “data-oldfiles” folder to “data” folder.

• Copy all databases from the data-old files and paste to the data folder.

• Now you have to copy the data file “ibdata1” & all log files “ib_logfile0, ib_logfile1 ” from data-old files folder to the data folder.

• If you have many id_logiles then copied all of them.

• Now Start MySQL from XAMPP.

• Go to phpMyAdmin to check all databases are available & working.

• Now start your any website project from localhost to check the MySQL database.
