三、linux操作系统版本号

**1、查看当前操作系统内核信息**

**uname -a**

$ uname -a

Linux vm-web 3.10.0-693.21.1.el7.x86\_64 \#1 SMP Wed Mar 7 19:03:37 UTC 2018 x86\_64 x86\_64 x86\_64 GNU/Linux

**2、查看当前操作系统版本信息**

**cat /proc/version**

$ cat /proc/version

Linux version 3.10.0-693.21.1.el7.x86\_64 ([builder@kbuilder.dev.centos.org][builder_kbuilder.dev.centos.org]) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) ) \#1 SMP Wed Mar 7 19:03:37 UTC 2018
