系統自動化安裝

啓動菜單介紹

Install or upgrade an existing system 安裝或升級html

Install system with basic video driver 在安裝過程當中發現顯卡驅動不支持，形成屏幕沒法顯示，這時選擇第二項，加載最基本的顯卡驅動，這樣讓界面可以顯示出來linux

Rescue installed system 救援模式express

Boot from local drive 從本地硬盤啓動vim

Memory test 內存的檢查centos

這幾項的區別就在於加的參數不一樣bash

選擇一項，按 tab 鍵就可進入編輯模式服務器

按 esc 鍵，在這個畫面能夠直接輸入指令，指令爲光盤文件的 isolinux/isolinux.cfg的 label 名app

五個標籤對應光盤開始菜單的五項less

系統安裝

詢問系統安裝源dom

安裝程序啓動過程

MBR：isolinux/boot.cat

stage2: isolinux/isolinux.bin

配置文件：isolinux/isolinux.cfg

每一個對應的菜單選項：

加載內核：isolinuz/vmlinuz

向內核傳遞參數：append initrd=initrd.img ...

裝載根文件系統，並啓動anaconda

默認啓動GUI接口

如果顯式指定使用TUI接口：向內核傳遞text參數便可

(1)按tab鍵,在後面增長text

(2)按ESC鍵：boot: linux text
