如何查看Linux操作系统版本?

如何查看linux系统版本?

  1. 查看内核版本命令:
    chen@mylinuxserver:~> cat /proc/version
    Linux version 2.6.5-7.244-smp (geeko@buildhost) (gcc version 3.3.3 (SuSE Linux)) #1 SMP Mon Dec 12 18:32:25 UTC 2005
    /proc 目录的作用?
    chen@mylinuxserver:/proc> uname -a
    Linux mylinuxserver 2.6.5-7.244-smp #1 SMP Mon Dec 12 18:32:25 UTC 2005 i686 i686 i386 GNU/Linux
    chen@mylinuxserver:/proc> uname -r
  2. 6.5-7.244-smp
    uname命令的作用?
  3. 查看Linux版本:
  1. 登录到服务器执行 lsb_release -a ,即可列出所有版本信息,例如:
    chen@mylinuxserver:/proc> lsb_release -a
    LSB Version: core-2.0-noarch:core-3.0-noarch:core-2.0-ia32:core-3.0-ia32:graphics-2.0-ia32:graphics-2.0-noarch:graphics-3.0-ia32:graphics-3.0-noarch
    Distributor ID: SUSE LINUX
    Description: SUSE LINUX Enterprise Server 9 (i586)
    Release: 9
    Codename: n/a
    注:这个命令适用于所有的linux,包括Redhat、SuSE、Debian等发行版。
  2. 登录到linux执行cat /etc/issue,例如如下:
    chen@mylinuxserver:/proc> cat /etc/issue
    Welcome to SUSE LINUX Enterprise Server 9 (i586) - Kernel
    (l).
  3. 登录到linux执行cat /etc/redhat-release ,例如如下:
    chen@mylinuxserver:/proc> cat /etc/release
    LSB_VERSION=”core-2.0-noarch:core-3.0-noarch:core-2.0-ia32:core-3.0-ia32”
    cat: /etc/lsb-release.d: 是一个目录
    SUSE LINUX Enterprise Server 9 (i586)
    VERSION = 9
    PATCHLEVEL = 3
