How to Fix MySQL Error 2015 - (CR_NAMEDPIPE_CONNECTION) %s via named pipe

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 2015 - (CR_NAMEDPIPE_CONNECTION) %s via named pipe. In this article, we will explore what this error means and how to fix it.

Understanding the MySQL Error 2015 - (CR_NAMEDPIPE_CONNECTION) %s via named pipe

The MySQL Error 2015 - (CR_NAMEDPIPE_CONNECTION) %s via named pipe occurs when there is a problem establishing a connection to the MySQL server using a named pipe. A named pipe is a method of inter-process communication on Windows systems. This error typically occurs when the MySQL client is unable to connect to the server through the named pipe.

There can be several reasons why this error occurs:

  • Incorrect MySQL server configuration
  • Problems with the named pipe itself
  • Firewall or security software blocking the connection

Fixing the MySQL Error 2015 - (CR_NAMEDPIPE_CONNECTION) %s via named pipe

Here are some steps you can take to resolve the MySQL Error 2015 - (CR_NAMEDPIPE_CONNECTION) %s via named pipe:

1. Check MySQL Server Configuration

Ensure that the MySQL server is configured to allow connections via named pipes. Open the MySQL configuration file (usually my.cnf or my.ini) and look for the following line:

enable-named-pipe

If this line is commented out (starts with a #), remove the comment and restart the MySQL server. If the line is not present, add it and restart the server.

2. Verify Named Pipe Settings

Check the named pipe settings on your system. The named pipe should be enabled and accessible. You can use the following command to check the named pipe status:

mysqladmin variables | grep named_pipe

If the named_pipe value is set to OFF, you need to enable it. Open the MySQL configuration file and add or modify the following line:

named-pipe

Set the value to ON and restart the MySQL server.

3. Check Firewall and Security Software

Firewalls and security software can sometimes block the connection to the MySQL server via named pipes. Ensure that the necessary ports and protocols are allowed through the firewall. You may need to consult your system administrator or IT department for assistance with this step.

Summary

The MySQL Error 2015 - (CR_NAMEDPIPE_CONNECTION) %s via named pipe can be resolved by checking the MySQL server configuration, verifying named pipe settings, and ensuring that firewalls and security software are not blocking the connection.
