報錯原因:
從MySQL 5.7向較低版本的MySQL 5.6搭建復制時,會觸發這個錯誤。
# mysqld -V mysqld Ver 5.6.20 for Linux on x86_64 (MySQL Community Server (GPL))
解決方法:
使用高版本的MySQL 5.6或5.7創建復制主機。
[root@db-backup-all ~]# /opt/mysql_56_40/bin/mysqld -V /opt/mysql_56_40/bin/mysqld Ver 5.6.40 for linux-glibc2.12 on x86_64 (MySQL Community Server (GPL))
