linux操作系統(tǒng)版本查看命令
在windows下我們查看系統(tǒng)信息直接右擊電腦屬性就可以查看了.那么在Linux系統(tǒng)中如何查看呢.下面大家與學習啦小編一起來學習一下linux操作系統(tǒng)版本的查看命令吧。
linux操作系統(tǒng)版本查看命令
一.查看內(nèi)核版本命令:
1) [root@SOR_SYS ~]# cat /proc/version
Linux version 2.6.18-238.el5 (mockbuild@x86-012.build.bos.redhat.com) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-50)) #1 SMP Sun Dec 19 14:22:44 EST 2010
[root@SOR_SYS ~]#
2)[root@SOR_SYS ~]# uname -r
2.6.18-238.el5
3)[root@SOR_SYS ~]# uname -a
Linux SOR_SYS.99bill.com 2.6.18-238.el5 #1 SMP Sun Dec 19 14:22:44 EST 2010 x86_64 x86_64 x86_64 GNU/Linux
[root@SOR_SYS ~]#
二.查看linux版本:
1) 登錄到服務器執(zhí)行 lsb_release -a ,即可列出所有版本信息,例如:
[root@SOR_SYS ~]# lsb_release -a
LSB Version: :core-4.0-amd64:core-4.0-ia32:core-4.0-noarch:graphics-4.0-amd64:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-amd64:printing-4.0-ia32:printing-4.0-noarch
Distributor ID: RedHatEnterpriseAS
Description: Red Hat Enterprise Linux AS release 4 (Nahant Update 4)
Release: 4
Codename: NahantUpdate4
[root@SOR_SYS ~]#
注:這個命令適用于所有的linux,包括Redhat、SuSE、Debian等發(fā)行版。
2) 登錄到linux執(zhí)行cat /etc/issue,例如如下:
[root@SOR_SYS ~]# cat /etc/issue
Red Hat Enterprise Linux Server release 5.6 (Tikanga)
Kernel \r on an \m
[root@SOR_SYS ~]#
3) 登錄到linux執(zhí)行cat /etc/redhat-release ,例如如下:
[root@SOR_SYS ~]# cat /etc/redhat-release
Red Hat Enterprise Linux AS release 4 (Nahant Update 4)
[root@SOR_SYS ~]#
注:這種方式下可以直接看到具體的版本號,比如 AS4 Update 1
4)登錄到linux執(zhí)行rpm -q redhat-release ,例如如下:
[root@SOR_SYS ~]# rpm -q redhat-release
redhat-release-5Server-5.6.0.3
[root@SOR_SYS ~]#
注:這種方式下可看到一個所謂的release號,比如上邊的例子是5
這個release號和實際的版本之間存在一定的對應關系,如下:
redhat-release-3AS-1 -> Redhat Enterprise Linux AS 3
redhat-release-3AS-7.4 -> Redhat Enterprise Linux AS 3 Update 4
redhat-release-4AS-2 -> Redhat Enterprise Linux AS 4
redhat-release-4AS-2.4 -> Redhat Enterprise Linux AS 4 Update 1
redhat-release-4AS-3 -> Redhat Enterprise Linux AS 4 Update 2
redhat-release-4AS-4.1 -> Redhat Enterprise Linux AS 4 Update 3
redhat-release-4AS-5.5 -> Redhat Enterprise Linux AS 4 Update 4
另:第3)、4)兩種方法只對Redhat Linux有效
5) [root@SOR_SYS ~]# file /bin/bash
/bin/bash: 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
[root@SOR_SYS ~]#
6) [root@SOR_SYS ~]# file /bin/cat
/bin/cat: 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
[root@SOR_SYS ~]#
Linux下如何查看版本信息, 包括位數(shù)、版本信息以及CPU內(nèi)核信息、CPU具體型號等等,整個CPU信息一目了然。
1、# uname -a (Linux查看版本當前操作系統(tǒng)內(nèi)核信息)
Linux localhost.localdomain 2.4.20-8 #1 Thu Mar 13 17:54:28 EST 2003 i686 athlon i386 GNU/Linux
2、# cat /proc/version (Linux查看當前操作系統(tǒng)版本信息)
Linux version 2.4.20-8 (bhcompile@porky.devel.redhat.com)
(gcc version 3.2.2 20030222 (Red Hat Linux 3.2.2-5)) #1 Thu Mar 13 17:54:28 EST 2003
3、# cat /etc/issue 或cat /etc/redhat-release(Linux查看版本當前操作系統(tǒng)發(fā)行版信息)
Red Hat Linux release 9 (Shrike)
4、# cat /proc/cpuinfo (Linux查看cpu相關信息,包括型號、主頻、內(nèi)核信息等)
processor : 0
vendor_id : AuthenticAMD
cpu family : 15

5、# getconf LONG_BIT (Linux查看版本說明當前CPU運行在32bit模式下, 但不代表CPU不支持64bit)
32
6、# lsb_release -a
