mysql_upgrade引起的mysql replication出错

公司mysql数据库服务器版本混合着用，逐步升级。在对mysql进行mysql_upgrade操作时，导致mysql复制错误了。信息如下： [ERROR] Slave SQL: Query caused different errors on master and slave. Error on master: message (format)='Column count of mysql.%s is wrong. Expected %d, found %d. The table is probably corrupted' error code=1547 ; Error on slave: actual message='no error', error code=0. Default database: 'performance_schema'. Query: 'DROP DATABASE IF EXISTS performance_schema', Error_code: 0 对主库进行mysql_upgrade操作时，会对performance_schema库进行操作。 只好跳过，这些操作。 mysql> stop slave; mysql> set gloabl sql_slave_skip_counter = 1; mysql> start slave; 升级需谨慎，小心操作。
