MySQL shutdown unexpectedly – Easy fix for the Server error

by Keerthi PS | Nov 16, 2019

Looking for how to resolve the error MySQL shutdown unexpectedly?

Usually, this error occurs due to corrupted files, improper shutdown, port changes, etc.

Database errors always need an immediate fix as it literally stops a website.

So, at Bobcares, we provide immediate fix MySQL errors, as a part of our Server Management Services.

Today, let’s see how our Support Engineers fix this MySQL error.

Why does MySQL shutdown unexpectedly?

This error usually shows up when the customer runs MySQL in a webserver. Corrupted files in the mysql/data folder are the reason for the error.

Similarly, port change, improper shutdown, missing related files, etc can lead to the same error. A similar error message in the XAMPP control panel appears as:

MySQL shutdown unexpectedly.

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 folder.

Then 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 = 1

Similarly, 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.
