--I don't know why I backed up on two machines with 5.6.33 installed, one of which automatically backs up the library Performance_schema, and the other machine doesn't. Strange. Some say it is unreasonable to upgrade the MySQL version caused. I don't know.
Due to import data times error 1142 (42000) at line 6688:select, LOCK TABLES command denied to user ' root ' @ ' localhost ' for table ' account S ',
Therefore, the performance_schema.accounts data in the backup file cannot be returned.
You can comment out or delete a backup statement about Performance_schema, and then restore it.
You can also explicitly not back up your system's own libraries in this way:
