1655 +During our debugging process it may there are some problems about Mysql， such as
1656 +
1657 +* MySQL: Host  192.168.XXX.XXX  is not allowed to connect.
1658 +* MySQL: Host  192.168.XXX.XXX  is blocked because of many connection errors.
1659 +* MySQL: SSL connection error: unknown error number.
1660 +* (((
1661 +1449-The user specified as a definer(‘mysql.infoschema‘@localhost‘) does not exist.
1662 +)))
1663 +
1664 +This type of problem has nothing to do with scripts or devices, it is a Mysql configuration issue. If you have any of these problems, please look for a solution online.
1665 +
1666 +{{info}}
1667 +✎Note: If you want to use CMD to access Mysql, you need to add the bin file to the environment variable, please check online for details of the operation.
