站长资讯网让电脑自动完成安装，我们要把分区、root口令等告诉电脑，我们用一个（应答文件的文本文件）将设置写入其中，让安装向导找到该应答文件即可自动安装。
准备素材：centos7、centos7mini(最小化安装版本)
##### A、[root@localhost ~]# ls anaconda-ks.cfg 此文件anaconda-ks.cfg为记录了我们是如何安装系统的。 ##### B、将网卡配置文件的 onboot 改为 yes [root@localhost ~]# vi /etc/sysconfig/network-scripts/ifcfg-ens33 TYPE=Ethernet PROXY_METHOD=none BROWSER_ONLY=no BOOTPROTO=dhcp DEFROUTE=yes IPV4_FAILURE_FATAL=no IPV6INIT=yes IPV6_AUTOCONF=yes IPV6_DEFROUTE=yes IPV6_FAILURE_FATAL=no IPV6_ADDR_GEN_MODE=stable-privacy NAME=ens33 UUID=bd070b36-c892-43b7-a8c8-d179b44c1d3c DEVICE=ens33 ONBOOT=yes ~ [root@localhost ~]# systemctl restart network ##### C、主机 centos7 ssh上远程的 centos7mini [root@centos7 ~]# ssh 192.168.58.133 root@192.168.58.133's password: Last login: Wed Jan 30 12:49:40 2019 from 192.168.58.1 [root@localhost ~]# scp anaconda-ks.cfg 192.168.58.254:/data root@192.168.58.254's password: anaconda-ks.cfg 100% 1421 120.3KB/s 00:00 [root@localhost ~]# exit logout Connection to 192.168.58.133 closed. 此处是将 anaconda-ks.cfg 文件拷贝到主机上 ##### D、我们可以把 anaconda-ks.cf 文件当做最小化安装的模板。如下： [root@centos7 ~]# cd /data [root@centos7 data]# ls anaconda-ks.cfg hallo.sh magedu.pubkey [root@centos7 data]# vim anaconda-ks.cfg #version=DEVEL # System authorization information auth --enableshadow --passalgo=sha512 # Use CDROM installation media cdrom # Use graphical install graphical # Run the Setup Agent on first boot firstboot --enable ignoredisk --only-use=sda # Keyboard layouts keyboard --vckeymap=us --xlayouts='us' # System language lang en_US.UTF-8 # Network information network --bootproto=dhcp --device=ens33 --onboot=off --ipv6=auto --no-activate network --hostname=localhost.localdomain # Root password rootpw --iscrypted $6$V2eP8pESlfKIToP8$NVcSm0geeSV4X1cd1lccrs9FAdK1rbj6EczSviVmoz75Znj5GaI.qY7jA0H1dmbh.hsI2ZIHtaR3Ko0/Xku9B1 # System services services --disabled="chronyd" # System timezone timezone Asia/Shanghai --isUtc --nontp "anaconda-ks.cfg" 48L, 1421C 1,1 Top ##### E、此时我们要先安装图像界面的文件，如下： [root@centos7 data]# yum install system-config-kickstart Loaded plugins: fastestmirror, langpacks Loading mirror speeds from cached hostfile base | 3.6 kB 00:00 epel | 4.7 kB 00:00 (1/2): epel/updateinfo | 954 kB 00:00 (2/2): epel/primary_db | 6.6 MB 00:01 Dependency Installed: gnome-python2.x86_64 0:2.28.1-14.el7 gnome-python2-canvas.x86_64 0:2.28.1-14.el7 libart_lgpl.x86_64 0:2.3.21-10.el7 libgnomecanvas.x86_64 0:2.30.3-8.el7 rarian.x86_64 0:0.8.1-11.el7 rarian-compat.x86_64 0:0.8.1-11.el7 system-config-date.noarch 0:1.10.6-3.el7.centos system-config-date-docs.noarch 0:1.0.11-4.el7 system-config-keyboard.noarch 0:1.4.0-5.el7 system-config-keyboard-base.noarch 0:1.4.0-5.el7 system-config-language.noarch 0:1.4.0-9.el7 usermode-gtk.x86_64 0:1.111-5.el7 Complete! ##### F、我们可以利用网络，搭建一个网络服务器，按照httpd的做法，
[root@centos7 ~]# rpm -ql httpd
/etc/httpd
/etc/httpd/conf
/etc/httpd/conf.d
/etc/httpd/conf.d/README
/etc/httpd/conf.d/autoindex.conf
/etc/httpd/conf.d/userdir.conf
/etc/httpd/conf.d/welcome.conf
/etc/httpd/conf.modules.d
/etc/httpd/conf.modules.d/00-base.conf
/etc/httpd/conf.modules.d/00-dav.conf
/etc/httpd/conf.modules.d/00-lua.conf
/etc/httpd/conf.modules.d/00-mpm.conf
/etc/httpd/conf.modules.d/00-proxy.conf
/etc/httpd/conf.modules.d/00-systemd.conf
/etc/httpd/conf.modules.d/01-cgi.conf
/etc/httpd/conf/httpd.conf
/etc/httpd/conf/magic
/var/www
/var/www/cgi-bin
/var/www/html
将httpd服务启动起来：
[root@centos7 ~]# systemctl start httpd
[root@centos7 ~]# cd /var/www/html
[root@centos7 html]# mkdir centos/{6,7}/os/x86_64/ -pv
[root@centos7 html]# tree
.
├── app
│?? ├── 6
│?? │?? └── x86_64
│?? └── 7
│?? └── x86_64
└── centos
├── 6
│?? └── os
│?? └── x86_64
└── 7
└── os
└── x86_64
12 directories, 0 files
[root@centos7 html]# mount /dev/sr0 centos/7/os/x86_64/
mount: /dev/sr0 is write-protected, mounting read-only
##### G、此时，我们可以去互联网访问主机了，如下： http://192.168.58.254/centos/7/ Index of /centos/7 [ICO] Name Last modified Size Description [PARENTDIR] Parent Directory - [DIR] os/ 2019-01-05 14:39 - 我们输入如下命令： [root@centos7 ~]# system-config-kickstart 这是图形界面，我们可以在弹出的页面中设置文件 ##### H、我们把centos7mini里的文件拷贝到centos7 上 [root@centos7 ~]# cd /data [root@centos7 data]# ls anaconda-ks.cfg hallo.sh magedu.pubkey [root@centos7 data]# mkdir /var/www/html/ks/; cp anaconda-ks.cfg /var/www/html/ks/centos7-mini.cfg ##### L、我们进入ks文件中查看 [root@centos7 data]# cd /var/www/html/ks [root@centos7 ks]# ls centos7-mini.cfg [root@centos7 ks]# ll total 4 -rw------- 1 root root 1421 Jan 30 22:10 centos7-mini.cfg [root@centos7 ks]# chmod a+r centos7-mini.cfg [root@centos7 ks]# ll total 4 -rw-r--r-- 1 root root 1421 Jan 30 22:10 centos7-mini.cfg 效果如下：
