Answers:
这意味着您正在运行32位内核,这意味着您只能在不使用仿真器或虚拟化的情况下运行32位应用程序。
如果要查看处理器是否为64位,请lm
在中列出的标志中查找/proc/cpuinfo
。
lscpu
可以使用,比较友好。
您可以使用lscpu
。
someuser@somelaptop:~$ lscpu
Architecture: i686 # <-- your kernel is 32 bit
CPU op-mode(s): 32-bit, 64-bit # <-- your cpu can handle 32 or 64 bit instructions
CPU(s): 4
Thread(s) per core: 2
Core(s) per socket: 2
CPU socket(s): 1
Vendor ID: GenuineIntel
CPU family: 6
Model: 37
Stepping: 5
CPU MHz: 1199.000
Virtualisation: VT-x
L1d cache: 32K
L1i cache: 32K
L2 cache: 256K
L3 cache: 3072K
“架构”领域的进一步说明:
X86, i686, or i386 means you are running a 32 bit kernel.
X86_64 , amd64 , or X64 means you are running a 64 bit kernel.
基本思路:
x86_64是支持64位的cpu,而i386是32位。
使用lcpu
长答案: lscpu

简短答案 lscpu | awk '/CPU op-mode/ {print}
输出: CPU op-mode(s): 32-bit, 64-bit
与lshw
长答案:跑 sudo lshw
答案略短: sudo lshw -c cpu
输出:
*-cpu

更短的答案: sudo lshw -c cpu | grep width
输出: width: 64 bits
uname -p
给出处理器的架构。如果给出x86_64
,则表示cpu是64位。
