[Linux] 不小心移除了 CentOS 7 的 GNOME Desktop!重新安裝回來
今天想要在 CentOS 7 上安裝 samba server,卻怎麼樣都設定不好,
後來看了一篇文章,裡面有個步驟是先移掉舊的 samba 元件,
於是我就照著在 terminal 裡面,執行 yum remove samba*:
testuser@localhost ~ $ sudo yum remove samba* ......

yum 出來的結果好長一串,仔細看的話,
yum 除了要移掉 samba 之外,還會把其他相依於 samba 元件的東西都移除掉,
像是 gdm, gnome-shell 等等一堆有的沒的,
但我那時沒仔細看,按下了 Yes…
這下子可不得了了,yum 才移除東西到一半,CentOS 的 GUI 畫面就突然消失,
閃了幾下之後,進入了久違的 multi-user 純文字模式…
一下子慌了手腳,我可是得靠 GUI 才能在 Linux 上活下去的呀 (<– 被 Windows 慣壞的小孩)
試著執行 yum install samba* 把 samba 的元件都再裝回去,但沒有用…
後來查到要先將 GNOME Desktop 這個群組的元件都先裝起來:
sudo yum groupinstall "GNOME Desktop"
GNOME Desktop 元件都安裝好了之後,執行 startx 是可以進入 GUI 畫面,
但是重開機的話,還是進到了 multi-user 純文字模式…
原來這是因為 gdm (GNOME Display Manager) 服務被停用的關係,
將它啟用、並且設定開機時使用圖形介面就行了:
sudo systemctl enable gdm sudo systemctl set-default graphical.target
這樣子再重新開機後,果然就回復原狀,以 GUI 方式登入了~
真是太好了,不用因為一個小錯誤搞到重灌呀~~
