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
LSBVersion::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
DistributorID:RedHatEnterpriseAS
Description:RedHatEnterpriseLinuxASrelease4(NahantUpdate4)
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
RedHatEnterpriseLinuxServerrelease5.6(Tikanga)
Kernel\ronan\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
RedHatEnterpriseLinuxASrelease4(NahantUpdate4)
[root@SOR_SYS~]#
注:这种方式下可以直接看到具体的版本号，比如AS4Update1
4)登录到linux执行rpm-qredhat-release,例如如下:
[root@SOR_SYS~]#rpm-qredhat-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->RedhatEnterpriseLinuxAS3
redhat-release-3AS-7.4->RedhatEnterpriseLinuxAS3Update4
redhat-release-4AS-2->RedhatEnterpriseLinuxAS4
redhat-release-4AS-2.4->RedhatEnterpriseLinuxAS4Update1
redhat-release-4AS-3->RedhatEnterpriseLinuxAS4Update2
redhat-release-4AS-4.1->RedhatEnterpriseLinuxAS4Update3
redhat-release-4AS-5.5->RedhatEnterpriseLinuxAS4Update4
另:第3)、4)两种方法只对RedhatLinux有效
