MySQL failed to start service error 1067 process terminated unexpectedly

Cause: Presumably because the database is not used for a long time, usually clean up the system garbage with clean software, the Temp folder under MySQL is cleaned out, causing the MySQL service to fail to start

Processing: 1, setting up the Temp folder in the installation directory (E:\MySQL\MySQL Server 5.7\temp)

2, add the following configuration statement under E:\MySQL\MySQL server 5.7\my.ini tmpdir= "E:/mysql/mysql server 5.7/temp/"

3. Restart the service.
