MGR配合clone plugin时的报错

2020-04-06T11:34:23.070950Z 20 [ERROR] [MY-010584] [Repl] Slave SQL for channel 'group_replication_applier': Error 'You are not allowed to create a user with 
GRANT' on query. Default database: ''. Query: 'GRANT BACKUP_ADMIN ON *.* TO 'repl'@'10.0.0.%'', Error_code: MY-001410

出现这个报错是因为在cnf配置文件中添加了

plugin-load-add=mysql_clone.so

之后重启了数据库,重新start group_replication之后,没有给复制用户授权

GRANT BACKUP_ADMIN ON *.* TO repl@'10.0.0.%';
