mysql清理relay log

As an AI language model, I don't have the ability to directly access the file system and manipulate databases. However, I can provide you with some general guidance on how to clear the relay logs in MySQL.

To clear the relay logs in MySQL, you can follow these steps:

1. Connect to the MySQL server using the command-line client or any MySQL client tool.

2. Use the following command to show the current status of the relay logs:

   SHOW SLAVE STATUS\G

This command will display the current status of the replication process, including the location of the relay logs.

3. Use the following command to stop the slave replication process:

   STOP SLAVE;

4. Use the following command to purge the relay logs:

   PURGE BINARY LOGS TO '<relay_log_file_name>';

Replace `<relay_log_file_name>` with the name of the relay log file that you want to remove. This command will remove all the relay logs up to and including the specified file.

5. Use the following command to start the slave replication process again:

   START SLAVE;

This command will restart the slave replication process with a new relay log file.

Note that clearing the relay logs may cause some data loss if the slave replication process is not up-to-date. Therefore, it's important to make sure that the slave replication process is fully caught up before clearing the relay logs.
