How does Windows fail to start the MySQL service error 1067 workaround?

Method One:

1, open My.ini file, find Default-storage-engine=innodb this line, change it to Default-storage-engine=myisam.
2. Remove Ib_logfile0 and Ib_logfile1 from the data directory in the MySQL installation directory
3. Locate the Infodb directory you specified when configuring the MySQL server to remove ibdata1
According to the My.ini file:
#*** INNODB Specific Options * * * innodb_data_home_dir= "d:/"

4. Restart the MySQL service

Method Two:
Reload MySQL, always prompt "Unable to start the MySQL service, error 1067 process unexpectedly stop restarting, repair the registry is useless, on-line check, change what basedir, also useless I use is mysql5.8, find to go to, remember before loaded wampserver,pc_ Webserver and other integrated environments, these software will write My.ini,php.ini to the C:windows directory, and set to read-only.
