Due to the need of the company's business to temporarily map the internal network database to the public network through the router port, in a short period of one hour, the password of the SA was changed by an unknown organization, resulting in an abnormal accident.

When an exception is found, the database is removed from the public network as soon as possible, and the SA password is attempted to recover. Baidu many places are mostly windows systems through local login to change the sa password, can not find the linux system to reset the SA password method, and finally think of the installation of the database when there is a step to set the SA password, check the installation documents, done.
