查看Linux系統(tǒng)版本信息的命令詳解
Linux系統(tǒng)下需要查看系統(tǒng)信息時(shí)使用命令是最快的方式。下面由學(xué)習(xí)啦小編為大家整理了查看Linux版本信息的命令詳解，希望對大家有幫助!
查看Linux系統(tǒng)版本信息的命令詳解
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(wù)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(gè)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(gè)所謂的release號，比如上邊的例子是5
這個(gè)release號和實(shí)際的版本之間存在一定的對應(yīng)關(guān)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 ~]#
