How to resolve errors during MySQL database synchronization?

There are several common solutions to the possible causes of database synchronization errors.

1. Check if the database connection is functioning properly: Make sure that the connection between the source database and the target database is working. You can try to reconnect or check the network configuration.
2. Check the database user permissions: ensure that the database user has sufficient permissions to perform synchronization operations, including the ability to read and write data.
3. Check the database version to ensure compatibility between the source and target databases; mismatched versions could result in synchronization failures.
4. Check synchronization configuration: Verify that the configuration parameters of the synchronization tool are correct, such as matching table names, field names, etc.
5. Check the log information: review the synchronization tool’s log information, analyze the error reasons, and make the necessary adjustments and fixes based on the error messages.
6. Restarting the synchronization service: Sometimes, restarting the synchronization service can solve some synchronization issues.

If the above methods still cannot resolve the issue, it is recommended to check the specific error message and further analyze and debug. You can refer to relevant documentation or seek technical support for help.
