While importing/transferring/compying database from one server to another sometimes you may get below error
Specified key was too long; max key length is 1000 bytes
I am not sure why this error occurs and there were lots of solutions available on the internet. Below is the solution that worked for me. I can’t say that it will work for you too but you can give it a try.
First of all stop the mysql service.
The remove the ib_logfile0 & ib_logfile1 from /var/lib/mysql or where ever your mysql data directory is.
mv ib_logfile0 ib_logfile0-backup
mv ib_logfile1 ib_logfile1-backup
Then start the mysql and import the database again
/etc/init.d/mysql start mysql database_name < database.sql
