uname 이라는 명령이 있습니다.
mysql performance를 좋게 하기위해 64bit server os 를 설치할 경우가 있습니다.
uname -rm ---> 이 명령을 가장 많이 사용합니다.

x86 이렇게 보이면 64bit os 로 설치 된것입니다.
옵션입니다. 참고하세요.
Print certain system information. With no OPTION, same as -s.
-a, --all print all information, in the following order,
except omit -p and -i if unknown:
-s, --kernel-name print the kernel name
-n, --nodename print the network node hostname
-r, --kernel-release print the kernel release
-v, --kernel-version print the kernel version
-m, --machine print the machine hardware name
-p, --processor print the processor type or "unknown"
-i, --hardware-platform print the hardware platform or "unknown"
-o, --operating-system print the operating system
--help display this help and exit
--version output version information and exit
