linux内核解压

linux内核解压说明：

首先下载内核linux-4.12.4.tar.xz

然后下载工具7z.rar

然后用winrar解压7z.rar

然后安装7z

然后用7z解压linux-4.12.4.tar.xz得到linux-4.12.4.tar

最后用winrar解压更多Linux介绍可查看《Linux就该这么学》。

二。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:

[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: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:

[root@SOR_SYS ~]# cat /etc/issue

Red Hat Enterprise Linux Server release 5.6 (Tikanga)

Kernel \r on an \m

[root@SOR_SYS ~]#

3) 登录到linux执行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:这种方式下可以直接看到具体的版本号，比如 AS4 Update 1

4)登录到linux执行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:这种方式下可看到一个所谓的release号，比如上边的例子是5

这个release号和实际的版本之间存在一定的对应关系，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)两种方法只对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 ~]#
