Understanding MySQL Error 1077 – SQLSTATE: HY000 (ER_NORMAL_SHUTDOWN): Interpreting Normal Shutdown Notifications

MySQL Error 1077 is not so much an error as it is a notification that the MySQL server has been shut down normally. When you come across this message, it indicates that the server has been intentionally stopped, which could be due to a variety of reasons, such as routine maintenance, system updates, or a manual shutdown command. This guide will help you understand the message and ensure that your MySQL shutdowns are smooth and intentional.

Interpreting Error 1077 (ER_NORMAL_SHUTDOWN)

The message accompanying Error 1077 typically includes the server’s hostname and the information that it has been shut down normally. It’s a part of MySQL’s normal logging process and is not indicative of an error that needs fixing. Instead, it serves as a confirmation that the server has stopped without encountering any issues.

Diagnosing the Reason for Shutdown

  1. Check the MySQL Logs: Review the MySQL logs to determine the context of the shutdown. Look for entries before the shutdown message to see if there was a command issued to stop the server:
grep 'shutdown' /var/log/mysql/error.log
  1. Review System Logs: System logs can provide additional information about why MySQL was stopped. This is useful if the server stopped due to system-level events:
journalctl -u mysql
  1. Check for Scheduled Tasks: If the shutdown occurs regularly, there might be a scheduled task (cron job) that stops the server:
crontab -l
  1. Consult with System Administrators: If you’re not the only one with access to the server, check with other administrators to see if they initiated the shutdown.

Ensuring Proper Shutdown and Restart

Manual Shutdown

If you need to manually shut down the MySQL server, use the following command for a safe shutdown:

mysqladmin -u root -p shutdown

Enter the root password when prompted.

Automated Shutdown

For automated shutdowns, such as those part of a backup or maintenance script, ensure that the script uses a proper shutdown command like the one above.

Restarting MySQL Server

To start the MySQL server after a normal shutdown, use the appropriate command for your system:

# For systems using systemd (like Ubuntu and CentOS 7 and above)
sudo systemctl start mysql

# For systems using init.d (like older versions of Ubuntu or CentOS)
sudo /etc/init.d/mysql start

Handling Unexpected Shutdowns

If the server was not intended to be shut down, investigate the cause, and take steps to prevent it from happening unexpectedly in the future. This might include configuring monitoring tools to alert you of system shutdowns or setting up proper access controls to limit who can shut down the server.


MySQL Error 1077 is a normal message indicating that the MySQL server has been shut down properly. It’s not an error to fix but rather a log entry that confirms a successful shutdown process. By understanding the context in which this message appears and ensuring that shutdowns are intentional and controlled, you can maintain the stability and availability of your MySQL service. Regular checks of system and MySQL logs can help you stay informed about the operational status of your server.
