有以下命令可以查看:

# lsb_release -a

Distributor ID: CentOS

这个命令适用于所有的linux,包括Redhat、SuSE、Debian、Centos等发行版。

root@MyMail ~ # uname -r

[root@localhost ~]# uname -a

Linux localhost.localdomain 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:35 EDT 2010 i686 i686 i386 GNU/Linux

以下二种方法适用于RedHat,CentOS

root@MyMail ~ # cat /etc/redhat-release

CentOS release 5.4 (Final)

登录到linux执行rpm -q redhat-release

#rpm -q redhat-release

或CentOS

root@MyMail ~ # rpm -q centos-release

centos-release-5-4.el5.centos.1

当前centos 版本与redhat对应的版本的命令

# cat /proc/version

Linux version 2.6.9-78.ELsmp (mockbuild@builder16.centos.org) (gcc version 3.4.6 20060404 (Red Hat 3.4.6-10)) #1 SMP Fri Jul 25 00:04:28 EDT 2008

方法:

1)[root@localhost ~]# cat /proc/version

2)

[root@localhost ~]# uname -a

Linux localhost.localdomain 2.6.18-194.el5 #1 SMP Fri Apr 2 14:58:14 EDT 2010 x86_64 x86_64 x86_64 GNU/Linux

3)

[root@localhost ~]# uname -r

2. 查看linux版本:

1) 列出所有版本信息,

[root@localhost ~]# lsb_release -a

LSB Version: :core-3.1-amd64:core-3.1-ia32:core-3.1-noarch:graphics-3.1-amd64:graphics-3.1-ia32:graphics-3.1-noarch

2) 执行cat /etc/issue,例如如下:

CentOS release 5.5 (Final)

Kernel r on an m

3) 执行cat /etc/redhat-release ,例如如下:

[root@localhost ~]# cat /etc/redhat-release

CentOS release 5.5 (Final)

查看系统是64位还是32位:

1、getconf LONG_BIT or getconf WORD_BIT

[root@localhost ~]# getconf LONG_BIT

64

2、file /bin/ls

[root@localhost ~]# file /bin/ls

/bin/ls: 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

3、lsb_release -a

[root@localhost ~]# lsb_release -a

LSB Version: :core-3.1-amd64:core-3.1-ia32:core-3.1-noarch:graphics-3.1-amd64:graphics-3.1-ia32:graphics-3.1-noarch

Distributor ID: CentOS
