问题介绍: 主库开始GTID,后来关闭了。做从库用的master_auto_position=1这种方法,然后报以下错误。
root@localhost :(none)02:49:31>change master to master_host='56.56.56.117', master_port=3306, master_user='repl',master_password='123456',master_log_file='mysql-bin.001081',master_log_pos=17071655;
ERROR 1776 (HY000): Parameters MASTER_LOG_FILE, MASTER_LOG_POS, RELAY_LOG_FILE and RELAY_LOG_POS cannot be set when MASTER_AUTO_POSITION is active.
解决的办法:

ERROR 1776 (HY000): Parameters MASTER_LOG_FILE, MASTER_LOG_POS, RELAY_LOG_FILE and RELAY_LOG_POS cannot be set when MASTER_AUTO_POSITION is active.
解决的办法:
由于之前用的master_auto_position=1,现在改回0,重新用pos方法change就可以了。
root@localhost :(none)02:49:41>change master to master_auto_position=0;Query OK, 0 rows affected (0.21 sec)
root@localhost :(none)02:52:50>change master to master_host='56.56.56.117', master_port=3306, master_user='repl',master_password='123456',master_log_file='mysql-bin.001081',master_log_pos=17071655;

本文解决了一个MySQL复制配置中常见的问题,即如何修复因GTID启用后又被禁用导致使用master_auto_position=1时出现的错误1776。通过将master_auto_position设置为0并重新指定master_log_file和master_log_pos,成功地解决了从库连接问题。
