查看linux版本及lsb release安装及一些想法

先说查看linux 内核方法

一：cat /proc/version

[python] view plain copy

1. <span style="font-family:'KaiTi_GB2312';font-size:18px;"># cat /proc/version
2. Linux version 2.6.32-358.el6.x86_64 (mockbuild@c6b8.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-3) (GCC) ) #1 SMP Fri Feb 22 00:31:26 UTC 2013</span>

二：uname -a[python] view plain copy

1. <span style="font-family:'KaiTi_GB2312';font-size:18px;"># uname -a
2. Linux mall-giftserver 2.6.32-358.el6.x86_64 #1 SMP Fri Feb 22 00:31:26 UTC 2013 x86_64 x86_64 x86_64 GNU/Linux</span>

再说查看linux 系统版本的方法一：lsb_release -a （此命令适用于所有的Linux发行版本）

[python] view plain copy

1. <span style="font-family:'KaiTi_GB2312';font-size:18px;"># lsb_release -a
3. LSB Version: :base-4.0-amd64:base-4.0-noarch:core-4.0-amd64:core-4.0-noarch
4. Distributor ID: CentOS
5. Description: CentOS release 6.4 (Final)
6. Release: 6.4
7. Codename: Final</span>

二：cat /etc/redhat-release （此方法只适合Redhat系的Linux）

[python] view plain copy

1. <span style="font-family:'KaiTi_GB2312';font-size:18px;"># cat /etc/redhat-release
3. CentOS release 6.4 (Final)
4. You have new mail in /var/spool/mail/root</span>

三：cat /etc/issue （此命令适用于所有的Linux发行版本）

[python] view plain copy

1. <span style="font-family:'KaiTi_GB2312';font-size:18px;"># cat /etc/issue
3. CentOS release 6.4 (Final)
4. Kernel \r on an \m</span>

然后再说安装lsb_release的过程吧在没有此命令的时候，执行会报命令不存在，咋办呢？一个方法：yum provides */lsb_release

当前命令的好处就是帮你找到哪里可以下载到这个lsb_release命令的地方

[python] view plain copy

1. # yum provides */lsb_release
3. Loaded plugins: fastestmirror
4. Loading mirror speeds from cached hostfile
5. * base: mirrors.aliyun.com
6. * extras: mirrors.btte.net
7. * updates: mirrors.aliyun.com
8. base/filelists_db | 6.4 MB 00:07
9. extras/filelists_db | 38 kB 00:00
10. updates/filelists_db | 3.5 MB 00:04
11. zabbix/filelists | 65 kB 00:00
12. zabbix-non-supported/filelists | 3.0 kB 00:00
13. redhat-lsb-core-4.0-7.el6.centos.i686 : LSB base libraries support for CentOS
14. Repo : base
15. Matched from:
16. Filename : /usr/bin/lsb_release
20. redhat-lsb-core-4.0-7.el6.centos.x86_64 : LSB base libraries support for CentOS
21. Repo : base
22. Matched from:
23. Filename : /usr/bin/lsb_release

如上所示，应该告诉我们在redhat-lsb-core-4.0-7.el6.centos.i686和redhat-lsb-core-4.0-7.el6.centos.x86_64这两处可以找到，我用的是后一个包中。于是按照下面方法执行

[python] view plain copy

1. yum install redhat-lsb-core-4.0-7.el6.centos.x86_64

之后就是一堆执行过程，大致截图如下

等到执行完毕我们验证一下。ok，已成功安装。

然后由安装这个lsb_release命令，新学到了一个方法，就是上面黄底标红的文字yum provides */。

意思就是通过目标命令名称，查找这个命令所属的安装包，比如本文我就是执行的yum provides */lsb_release

以后如果不知道某个命令从哪儿安装，可以考虑使用这个命令来查找。
