如何查看Linux操作系统版本
1. 查看内核版本命令:
[root@tg ]# cat /proc/version Linux version 3.10.0-693.2.2.el7.x86_64 (builder@) (gcc version 4.8.5 20150623 (Red Hat 4.8.5-16) (GCC) ) #1 SMP Tue Sep 12 22:26:13 UTC 2017
[root@tg ]# uname -a Linux tg 3.10.0-693.2.2.el7.x86_64 #1 SMP Tue Sep 12 22:26:13 UTC 2017 x86_64 x86_64 x86_64 GNU/Linux
[root@tg ]# uname -r 3.10.0-693.2.2.el7.x86_64
2. 查看Linux版本:
1) 执行 lsb_release -a ,即可列出所有版本信息,例如:
[root@tg ]# lsb_release -a LSB Version: :core-4.1-amd64:core-4.1-noarch Distributor ID: CentOS Description: CentOS Linux release 7.5.1804 (Core) Release: 7.5.1804 Codename: Core
注:这个命令适用于所有的linux,包括Redhat、SuSE、Debian等发行版。
2) 执行cat /etc/issue,例如如下:
[root@tg ]# cat /etc/issue \S Kernel \r on an \m
3) 执行cat /etc/redhat-release ,例如如下:
[root@tg ]# cat /etc/redhat-release CentOS Linux release 7.5.1804 (Core)
