本文介绍了通过查看特定文件的属性来确定CentOS系统是32位还是64位的方法。对于32位系统，使用file /sbin/init或file /bin/ls会显示ELF32-bit；对于64位系统，则会显示ELF64-bit。此外，还可以使用uname -a命令进一步确认系统架构。

如何看CentOS系统是32位还是64位的？

32位系统：

[root@localhost ~]# file /sbin/init
/sbin/init: ELF 32-bit LSB shared object, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped
[root@localhost ~]# file /bin/ls
/bin/ls: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped

64位系统：

[root@localhost ]# file /sbin/init
/sbin/init: ELF 64-bit LSB shared object, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped
[root@localhost ]# file /bin/ls
/bin/ls: ELF 64-bit LSB executable, x86-64, version 1 (SYSV), dynamically linked (uses shared libs), for GNU/Linux 2.6.18, stripped
[root@localhost ]# uname -a
Linux localhost.localdomain 2.6.32-431.el6.x86_64 #1 SMP Fri Nov 22 03:15:09 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux
