Common MySQL Connection Errors

Many websites use MySQL databases to store information and settings. However, there are some reasons why the connection to the database may fail. This article describes some commonly seen error messages when connecting to a database, as well as some general tips to keep in mind when setting up a database connection. Common Error Messages Using MySQL is great, but the error message returned if there is an issue logging in to your database can be quite confusing. Here are some commonly seen error…

Connection failed: SQLSTATE[HY000] [2002] No such file or directory

If you have set the database hostname in a configuration file, but you still get this error, that’s usually caused by either an error in the configuration value or a bug in the script (where it doesn’t actually use the database hostname for the connection parameters). Again, this error is 100% guaranteed to be caused by using localhost. There is no other situation where this error can occur.
