Why Can't I Connect to My MySQL Server?

Can't Establish Connection to MySQL Server?

If you're encountering error code 2013, indicating a lost connection to your MySQL server during a query, it's essential to troubleshoot the underlying cause.

Causes of Connection Loss:

  • Insufficient database memory size
  • Exceptionally large data being imported

Solutions:

1. Increase max_allowed_packet Value:

Edit your my.cnf or my.ini file and modify the "max_allowed_packet" parameter under the [mysqld] section to a value of at least 32M. This parameter specifies the maximum size of packets that MySQL can send or receive.

2. Use Command-Line Import:

If the problem persists, consider importing the data from the command line using the following syntax:

mysql -u <username> --password=<password> <database_name> <file_to_import>
Copy after login

Ensure that your username, password, and database name are correct.
