Shut down the server cleanly, and move away (don't delete) the log files, which are in /var/lib/mysql and named ib_logfile0, ib_logfile1, and so on. Change the innodb_log_file_size setting. Then restart the server. Test to see if the server is working; if all is well, you can delete the log files you moved.
