CentOS6.5 Amin Teacher recommended Universal partition:
/boot 100M;
/20G;
/usr/20g;
Swap memory is less than 8G to twice times the memory, greater than 8G to 16G;
The remaining space is divided to/data/
To see if the system is 32-bit or 64-bit use command uname-a if the display has x86_64 is a 64-bit system, and the display i386,i586 or i686 is a 32-bit system.
