linux下如何查看内核版本和系统版本信息

查看系统内核的方法：
1、uname -r
2、cat /proc/version

[root@localhost ~]# uname -r
2.6.32-504.8.1.el6.i686

[root@localhost ~]# cat /proc/version
Linux version 2.6.32-504.8.1.el6.i686 (mockbuild@c6b9.bsys.dev.centos.org) (gcc version 4.4.7 20120313 (Red Hat 4.4.7-11) (GCC) ) #1 SMP Wed Jan 28 18:25:26 UTC 2015

查看系统版本的方法：
1、cat /etc/issue
2、cat /etc/system-release 软连接文件，实际连接到centos-release
3、cat /etc/redhat-release 软连接文件，实际连接到centos-release
4、cat /etc/centos-release
5、rpm -qa | grep release
6、lsb_release -a
LSB是Linux Standard Base的缩写，lsb_release命令用来显示LSB和特定版本的相关信息，可通过yum -y install redhat-lsb命令安装。
