[ERROR] Slave SQL for channel '': worker thread retried transaction 10 time(s) in vain, giving up. Consider raising the value of the slave_transaction_retries variable. Error_code: 1205

这个错误提示是MySQL数据库的同步机制出现问题,其中slave_transaction_retries是一个系统变量,它用于控制在一个事务中重试操作的次数。当slave在执行一个事务时,如果在指定的重试次数内无法成功执行该事务,就会显示上述错误信息。
如果你遇到了这个问题,可以通过修改slave_transaction_retries的值来解决。例如,将其增加到更高的数字,例如100或更多,以增加重试操作的次数。你可以使用以下命令来修改该值:
```
SET GLOBAL slave_transaction_retries=100;
```
注意,修改系统变量需要具有足够的权限,因此您可能需要使用root用户或具有适当权限的用户来执行此操作。

Fatal error: The slave I/O thread stops because master and slave have equal MySQL server UUIDs; these UUIDs must be different for replication to work.
这是一个MySQL数据库主从复制的错误。当主库和从库的服务器UUID相同时,从库会停止I/O线程以防止数据不一致。为了解决这个问题,您需要在从库上运行以下命令:
```
stop slave;
SET GLOBAL server_uuid = UUID();
start slave;
```
这将停止从库的复制,生成一个新的UUID,并重新启动从库的复制。请注意,如果从库和主库使用相同的复制通道,则必须在主库上执行相同的操作以生成新的UUID。
ERROR 1200 (HY000): The server is not configured as slave; fix in config file or with CHANGE MASTER TO
This error message indicates that the MySQL server is not configured as a slave server in a replication setup. To fix this issue, you need to either update the configuration file or use the CHANGE MASTER TO command to configure the server as a slave.
To update the configuration file, you need to open the MySQL configuration file (my.cnf or my.ini) and add the following lines under the [mysqld] section:
server-id = <unique ID>
log-bin = <binary log file name>
Replace <unique ID> with a unique number and <binary log file name> with a filename for the binary log file. Save the changes and restart the MySQL server for the changes to take effect.
Alternatively, you can use the CHANGE MASTER TO command to configure the server as a slave. The command syntax is as follows:
CHANGE MASTER TO
MASTER_HOST='<hostname>',
MASTER_USER='<username>',
MASTER_PASSWORD='<password>',
MASTER_LOG_FILE='<binary log file>',
MASTER_LOG_POS=<position>;
Replace <hostname>, <username>, <password>, <binary log file>, and <position> with the appropriate values for your replication setup. Run this command on the server that you want to configure as a slave.
Once you have configured the server as a slave, you should be able to start the replication process.
