Cause of error

The Mysqld_safe is the Mysqld_safe tool under the MySQL5.6.37 version
Using MySQL5.7.19 's Mysqld_safe tool is OK.

The direct use of Mysqld_safe is called the Mysqld_safe in the 5637 directory and cannot be started

Error log

Specify the full directory of Mysqld_safe to start MySQL is ok
