篇首语：本文由小常识网(cha138.com)小编为大家整理，主要介绍了Centos7安装桌面视图环境相关的知识，希望对你有一定的参考价值。

参考技术A 我最近安装了CentOS 7，当时做的是最小安装，没有GUI，而现在我想在其中安装一个GUI环境，那么，如何在先前安装的CentOS 7上安装桌面环境而不用重新安装系统呢？

使用yum group 安装的桌面环境大小

yum的用法

[user@sgk_entos7 ]# yum repolist

CentOS 7默认的GNOME桌面以经典模式开始，但如果要使用GNOME Shell，则需要做如下设置：

选项A：如果使用 startx 启动GNOME，请设置如下：

选项B：设置系统图形登录 systemctl set-default graphical.target 并重启系统。系统启动后

转linux Centos 6.5 安装桌面环境GNOME

在某种场合之下，我们使用的Linux还是要选择安装桌面环境的，所以在这里介绍一下如何给没有安装桌面环境的系统安装桌面环境。以Centos 6.5 为例演示一下如何安装桌面环境。

一、首先查看系统的运行级别以及是否安装了桌面环境

1、使用命令 runlevel 查看当前的运行级别，如图所示

2、使用命令 yum grouplist | more 查看是否安装了桌面环境的组件，如图所示 二、再次从上面分析的结果看到，当前运行级别是3，而且也没有安装桌面环境的软件。

然后我们使用命令查看一下桌面有哪些桌面环境的软件，然后装显示出来的软件组件就可以了。例如：

[[email protected] ~]#

[[email protected] ~]# yum grouplist | more

===========================================

从上面的软件组信息，挑选与桌面环境有关的软件组，然后安装即可，我下面选择的软件组与输入法还有字体等桌面环境需要用到的供大家参考一下。

yum groupinstall -y "Desktop" "Desktop Platform" "Desktop Platform Development" "Fonts" "General Purpose Desktop" "Graphical Administration Tools" "Graphics Creation Tools" "Input Methods" "X Window System" "Chinese Support [zh]" "Internet Browser"

后面的是安装软件过程，需要等等一阵时间。
