Add swap file in LInux

In my exapmle i increase 512mb RAM and create 1 gb swap space for it. Not use another hdd. But i strongly recommend alwayz use HDD.

create swap file use this cmd.
#dd if=/dev/zero of=/swapfile bs=1024 count=1022976 (*999mb)
#mkswap /swapfile
enable swap file immeditae

For parament save entry in /etc/fstab file. like this
