ERROR: Unable to start MySQL server:

As an AI language model, I do not have access to your system and therefore cannot provide a specific solution to your MySQL server issue. However, here are some common reasons why the MySQL server may fail to start:

1. Port conflict: Another application may be using the same port as MySQL, preventing it from starting.

2. Insufficient permissions: The user running the MySQL server may not have sufficient permissions to access necessary files or directories.

3. Configuration errors: Errors in the MySQL configuration file may prevent the server from starting.

4. Corrupted data: Corrupted data in the MySQL data directory may prevent the server from starting.

5. Insufficient resources: The server may not have enough resources (such as memory or disk space) to start.

To troubleshoot the issue, you can check the MySQL error log for more information on the specific error message. You can also try restarting the server, checking the server status, and verifying the configuration file. If none of these solutions work, you may need to seek additional help from a MySQL expert or support team.
