Determine Linux Server's Architecture (32 or 64 bit) [duplicate]

  • 772

I actually just have shared hosting at Dreamhost, and I'm going to use it to test deploying a MongoDB based application. There are 32-bit and 64-bit pre-built distros, but I don't know which I should install, until I can determine the server's architecture.

I suppose this can be done by detecting the OS version, but I have no idea how to do that. I can ssh in, though not as root of course, since it's a shared server. I just need to know what command or commands can tell me what architecture is being run on.

linux

  2. The command on Linux/UNIX is:

    uname -a

    or for just the architecture:

    uname -m

  3. From commandlinefu.com:

    getconf LONG_BIT

  4. I think uname may just show you the version of the operating system that's installed, rather than the underlying hardware architecture. To double check, try:

    cat /proc/cpuinfo

  5. lshw shows the processor register width like this: 

    
sudo lshw -class processor

  6. there are five different ways in which it can be done:

    1. uname -a

    2. uname -m

    3. file /sbin/init

    4. arch

    5. through system settings, (for ubuntu > 12.04)
