全库导出时没有权限访问performance_schema
我在mysql 5.5下多实例的环境下做一个全库导出，命令为mysqldump -uroot -pmysql -S /u01/app/mysql/3306/mysql.sock -A -B --events --master-data=2 > /u01/app/mysql/rep.sql结果报错，不知道是什么原因：mysqldump: Couldn't execute 'show events': Access denied for user 'root'@'localhost' to database 'performance_schema' (1044)
