实验自动化安装

企业开发 2019-01-31 08:10:46 阅读次数: 0

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
[email protected]'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
[email protected]'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

(2/2): epel/primary_db                      | 6.6 MB   00:01     
Dependency Installed:
  gnome-python2.x86_64 0:2.28.1-14.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：

http://192.168.58.254/ks/centos7-mini.cfg
