Check whether the Linux server is 32-bit or 64-bit

ViewLinuxThe machine is32Bit or64Bit method:

1. Method1:

file/sbin/init or file/bin/ls

/sbin/init: Elf 64-bit LSB executable, x86-64 , Version 1 (sysv) , dynamically linked (uses SHARED libs) , for GNU/Linux 2.6.18 , stripped

If64-bitIs64Bit;

File/sbin/init

/sbin/init: Elf 32-bit LSB executable, intel 80386 , Version 1 (sysv) , for GNU/Linux 2.2.5 , dynamically linked (uses SHARED libs) , stripped

If32 bitIs32bit;

i686 32 bit machine; i686 only i386 a subset of , supported CPU from Pentium 2 (686) start, the previous model does not support .

note:

1. i386 is applicable to intel and amd all 32 bit CPU , and via use x86 architecture 32 CPU .

Intel Platform includes 8086,80286,80386,80486, Pentium series(1.2.3.4), Saeyang series,Pentium dSeries andCentrino P-M,Core Duo .

2. x86_64 for intel Core 2 Duo , Centrino Core 2 Duo , and Xeon and amd athlon64/X2 , sempron64/X2 , duron64 use x86 architecture 64 bit CPU.

3. PPC appliesApple Macintosh G3,G4,G5,PowerBook,And other non-Intel Models

InstallDVDMore software is included than the installation CD.DVDTwo graphical interfaces are also included.(KDEAndGnome).

4. jigdo

You can also use Jigdo Download Fedora Release version. Jigdo You can download ISO Image. Same BT The download wait task is completely completed, Jidgo Automatically locates the fastest backup storage ( Pass Fedora Image Manager ) And download the required files. To reduce the required network traffic Jigdo Scan existing DVD Or CD Media. This feature is particularly useful to the following users.

Getconf long_bit

In32Bitwise AND64The result is as follows:

[B @ 002 ~] $ Getconf long_bit

64

[Root @ pmx4/] # getconf long_bit
