This short tutorial was tested on CentOS 5 but it works for any version of Linux, in the end the console is the same for everyone.
console to burn, we need have a CD burner / DVD, Enough CD / DVD where you burn, what we burn and install the following programs below.
# yum-y install cdrecord mkisofs
need to create one. ISO of what we want to burn. For this we use the mkisofs command
# mkisofs-r-l-o imagen_que_quiero_crear.iso / home / data_que_quiero_quemar
More or less we will leave the following information
INFO: UTF-8 character encoding detected by locale settings.

-input-charset to override.
