i have done change the max_execute_time to 90,then there is some error again like this
ERROR. Check your login credentials. unable to execute SQL: ‘create database openemr character set utf8 collate utf8_general_ci’ due to: Can’t create database ‘openemr’; database exists
If you partially made it through the installation, setup may have already created the database, and brought you to some state that setup could not recover from. If you don’t have data you care about, you may drop the openemr database and begin the installation again with your new php.ini settings.
$ mysql -u root -p [then enter password at prompt]
$ DROP DATABASE openemr;
