linux系統版本命令linux
1、查看系統內核版本命令:
bash
1)[root@pgserver04 ~]# cat /proc/version Linux version 2.6.18-238.el5PAE (mockbuild@ls20-bc2-13.build.redhat.com) (gcc version 4.1.2 20080704 (Red Hat 4.1.2-50)) #1 SMP Sun Dec 19 14:42:44 EST 2010 [root@pgserver04 ~]#
2)[root@pgserver04 ~]# uname -r 2.6.18-238.el5PAE
3)[root@pgserver04 ~]# uname -a Linux pgserver04 2.6.18-238.el5PAE #1 SMP Sun Dec 19 14:42:44 EST 2010 i686 i686 i386 GNU/Linux [root@pgserver04 ~]#
2、查看linux版本:ide
1)執行 lsb_release -a ,便可列出全部版本信息:
ui
[root@pgserver04 ~]# lsb_release -a LSB Version: :core-4.0-ia32:core-4.0-noarch:graphics-4.0-ia32:graphics-4.0-noarch:printing-4.0-ia32:printing-4.0-noarch Distributor ID: RedHatEnterpriseServer Description: Red Hat Enterprise Linux Server release 5.6 (Tikanga) Release: 5.6 Codename: Tikanga
注:這個命令適用於全部的linux,包括Redhat、SuSE、Debian等發行版。spa
2) 執行cat /etc/issue,例如以下:orm
[root@pgserver04 ~]# cat /etc/issue Red Hat Enterprise Linux Server release 5.6 (Tikanga) Kernel \r on an \m
3) 執行cat /etc/redhat-release server
[root@pgserver04 ~]# cat /etc/redhat-release Red Hat Enterprise Linux Server release 5.6 (Tikanga) [root@pgserver04 ~]#
注:這種方式下能夠直接看到具體的版本號,好比 AS4 Update 1ip
4)執行rpm -q redhat-release ,例如以下:it
[root@pgserver04 ~]# rpm -q redhat-release redhat-release-5Server-5.6.0.3 [root@pgserver04 ~]#
注:這種方式下可看到一個所謂的release號,好比上邊的例子是5io
這個release號和實際的版本之間存在必定的對應關係,以下:
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
注:第3)、4)兩種方法只對Redhat Linux有效
