The server quit without updating PID file (/usr/local/mysql/data/mysql.pid).

It seems that the MySQL server has encountered an issue while updating the PID file. This file is used to store the Process ID (PID) of the running MySQL server. When the server quits unexpectedly, it may fail to update this file.

To address this issue, you can try the following steps:

1. Check the MySQL error log: Look for any error messages or warnings related to the server shutdown. The error log usually resides in the MySQL data directory.

2. Verify file permissions: Ensure that the user running the MySQL server has proper permissions to read and write to the data directory and PID file.

3. Remove the PID file: If the server has already quit, you can try removing the PID file manually. Run the following command:

   sudo rm /usr/local/mysql/data/mysql.pid

4. Restart the MySQL service: After removing the PID file, restart the MySQL service using your preferred method (e.g., systemctl, service, etc.).

If the issue persists or you need further assistance, please provide more details about your environment and any relevant error messages.
