Linux查看版本及配置相关命令
一、查看系统版本命令
1.查看内核版本命令
language
cat /proc/version
uname -r
uname -a2.查看linux版本命令
language
lsb_release -a注:这个命令适用于所有的linux，包括Redhat、SuSE、Debian等发行版。
language
cat /etc/issue
cat /etc/redhat-release 注:这种方式下可以直接看到具体的版本号。
language
rpm -q redhat-release注:这种方式下可看到一个所谓的release号
这个release号和实际的版本之间存在一定的对应关系，如下：
language
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 42.只对Red hat linux有效的两种方法：
language
