How we fix the error MySQL shutdown unexpectedly?
Our Support Engineers with expertise over a decade fix the database errors for our customers. Let’s now check out how we fix this MySQL error.
1. Irregular files
Initially, our Support Engineers check for corrupted files in the MySQL folder.
For instance, in the XAMPP server, we go to
C:\xampp\mysql\data folderThen we look for redo log files. This file indicates an unexpected shutdown. So, after a clean shutdown, we delete the redo logs( .ibd or .ibdata files).
Finally, we restart the XAMPP server. Mostly this fixes the error.
2. Configuration changes
Sometimes, the removal of corrupted files cannot resolve the error. In such cases, our Support Engineers execute a force recovery of InnoDB.
For this, we open the MySQL config file. Here we add the code under the mysqld section.
innodb_force_recovery = 1Similarly, we check the MySQL port number updated in the configuration file. We always choose lower values for InnoDB force recovery as it is relatively safe that only some data on corrupt individual pages will be lost.
Either way, we always take enough backup prior to the configuration changes. This helps to prevent data loss at any cost.
