如何判斷Linux是32位還是64位

link ica rip long gnu x86 inux get conf
方法一:getconf LONG_BIT
在linux終端輸入getconf LONG_BIT命令
如果是32位機器,則結果為32
- [root@localhost ~]# getconf LONG_BIT
- 32
如果是64位機器,則結果為64
- [root@localhost ~]# getconf LONG_BIT
- 64
方法二:uname -a
如果是64位機器,會輸出x86_64
- [chenzhou@testweb01 ~]$ uname -a
- Linux testweb01 2.6.18-308.4.1.el5 #1 SMP Tue Apr 17 17:08:00 EDT 2012 x86_64 x86_64 x86_64 GNU/Linux
可以看到,uname-a執行後的結果中輸出了x86_64,說明該機器是64位的,否則代表該機器是32位的
- [root@localhost ~]# uname -a
- Linux localhost.localdomain 2.6.18-164.el5 #1 SMP Tue Aug 18 15:51:54 EDT 2009 i686 i686 i386 GNU/Linux
方法三:file /sbin/init 或者 file /bin/ls
示例:32位機器
file /sbin/init
- [root@localhost ~]# file /sbin/init
- /sbin/init: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped
file /bin/ls
- [root@localhost ~]# file /bin/ls
- /bin/ls: ELF 32-bit LSB executable, Intel 80386, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped
示例:64位機器
file /sbin/init
- [chenzhou@testweb01 ~]$ file /sbin/init
- /sbin/init: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped
file /bin/ls
- [chenzhou@testweb01 ~]$ file /bin/ls
- /bin/ls: ELF 64-bit LSB executable, AMD x86-64, version 1 (SYSV), for GNU/Linux 2.6.9, dynamically linked (uses shared libs), for GNU/Linux 2.6.9, stripped
可以通過命令結果中的64-bit或者32-bit來判斷該機器是64位還是32位
