Mysql service cannot be started

Mysql service cannot be started. mysql was installed in windows yesterday and cannot be started after the service is installed. Solution: 1. run "mysqld -- console" in the directory where mysqld.exe is located. At this time, the console displays a specific Error message, which includes the following two sentences: InnoDB: Error: log file/usr/local/mysql/data/ib_logfile0 is of different size 0 104857600 bytes InnoDB: than specified in. cnf file 0 134217728 bytes! 2. Open the mysql. ini file and change innodb_log_file_size to 104857600. Note: The default value may be 52 MB. You can directly change the 52M value to the number above without any unit. 3. Start the service again, or run mysqld -- console again. Note: This may only happen when MySQL has been installed before. In addition, if the default engine is set to MyISAM, it can be started normally, but INNODB database engine cannot be created.
