Solution process:

I am using the MySql5.5 version of the database. When the above error occurs, first use the command -》show engines; to check the engine details:

It is found that there is no innodb entry:

Then we check the log File:

If you don’t know the location of the winddowns log file, you can use the command ->show variables like '%error%'; to view

Then: In the log we found:

The error lies in the incorrect content of the ibdata1 file.

Next, we turn off the data service, delete the ibadata1 file in the installation directory, and the two files in the same directory as the error log: see the picture below

After the deletion is successful, change the my.ini file parameters.

innodb_buffer_pool_size = 256M

innodb_log_file_size  = 256M

innodb_thread_concurrency = 16

innodb_flush_log_at_trx_commit = 2

innodb_flush_method  = normal

Among them, innodb_flush_method = normal is added last, and other parameters are included in the original configuration file.

After the changes are completed, save and restart the mysql service.

Execute again-》show engines;

It is found that innoDB can be used, which means success.

Run the file just now and it will run perfectly.
