[Koha] confusing sudo a2enmod rewrite command

Dear Friend, Our server OS is Red Hat EL-5. EL-5 has not Apache 2. Our system admin confused with the command "sudo a2enmod rewrite" while Koha 3 installation. He says that this command work only with Apache 2. How can we manage this command with EL-5? Any equivalent command available? or any other way to execute this command? With thanks, Vimal Kumar Asst.
