How to Fix MySQL Error 2021 - (CR_EMBEDDED_CONNECTION) Embedded server

MySQL is a popular open-source relational database management system used by many websites and applications. However, like any software, it can encounter errors that can disrupt its normal operation. One such error is the MySQL Error 2021, also known as (CR_EMBEDDED_CONNECTION) Embedded server error. In this article, we will explore what this error means and provide steps to fix it.

Understanding MySQL Error 2021

MySQL Error 2021 occurs when there is an issue with the embedded server connection. The embedded server is a feature of MySQL that allows applications to run an instance of the MySQL server within their own process, rather than connecting to a separate MySQL server. This error typically occurs when there is a problem with the embedded server configuration or when the embedded server is unable to start.

Possible Causes of MySQL Error 2021

There can be several reasons why you might encounter the MySQL Error 2021. Some common causes include:

  • Incorrect configuration settings for the embedded server
  • Missing or corrupted files related to the embedded server
  • Insufficient permissions for the application to access the embedded server
  • Conflicts with other software or services running on the same system

Steps to Fix MySQL Error 2021

Here are some steps you can take to resolve the MySQL Error 2021:

1. Check Configuration Settings

Verify that the configuration settings for the embedded server are correct. This includes checking the configuration file (usually named "my.ini" or "my.cnf") for any errors or inconsistencies. Make sure the necessary paths, ports, and other settings are properly configured.

2. Verify File Integrity

Ensure that all the required files for the embedded server are present and not corrupted. If any files are missing or damaged, you may need to reinstall MySQL or restore the missing files from a backup.

3. Check Permissions

Ensure that the application has sufficient permissions to access the embedded server. This includes both file system permissions and MySQL user permissions. Make sure the application has the necessary privileges to read and write files, as well as connect to the MySQL server.

4. Resolve Software Conflicts

If you suspect that other software or services running on the same system are causing conflicts with the embedded server, try temporarily disabling or stopping them to see if the error persists. You can also try running the embedded server on a different port to avoid conflicts.

5. Seek Professional Help
