## linux----自动安装虚拟机脚本制作方法 ##

需要先搭建dhcp,详情请看[添加链接描述][Link 1]  
以及一个和系统用版本的镜像

共三步：

kickstart概述:  
使用kickstart，系统管理员可以创建一个包含安装期间所有常见问题的答案的文件，以自动安装Red Hat Enterprise Linux

1）Kickstart制作工具安装

软件包 system-config-kickstart

[root@foundation72 ~]# yum install system-config-kickstart -y         ##安装
    [root@foundation72 ~]# system-config-kickstart                               ##kickstart

2）制作kickstart软件包  
看图

到此可以保存到/ks目录里了

3)完善制作的kickstart软件包

[root@foundation72 ks]# vim ks.cfg                 
    #################################完善kickstart软件包
     40 %post
     41 cat >/etc/yum.repos.d/yum.repo <<EOF

     45 gpgcheck=0                                               ##不校验下载软件是否为红帽公司授权
     46 EOF
     47 %end
     48 
     49 %packages
     50 @base                                                      ##系统最基本组建

     52 %end
    #################################
    [root@foundation72 ks]# ksvalidator ks.cfg     ##检测ks.cfg是否有语法错误

[root@foundation72 html]# cp /ks/ks.cfg /var/www/html/
    [root@foundation72 ~]# systemctl restart httpd
    [root@foundation72 html]# systemctl stop firewalld
    [root@foundation72 html]# systemctl disable firewalld

<table> 
 <tbody> 
  <tr> 
   <td>二、运行脚本安装虚拟机 </td> 
  </tr> 
 </tbody> 
</table>

两步  
1）编写安装虚拟机的脚本

vim xuniji.sh
    #################编写脚本
      1 #!/bin/bash
      2 virt-install \
      3 --name $1 \
      4 --memory 1000 \
      5 --vcpus 1 \
      6 --disk /var/lib/libvirt/images/$1.qcow2,size=8,bus=virtio \
      7 --network bridge=br0,model=virtio \
      8 --location http://172.25.254.72/7.3-x86_64-dvd.iso/ \
      9 --extra-args "ks=http://172.25.254.72/ks.cfg" &> /dev/null &
    #################

2）运行安装虚拟机

sh xuniji.sh uc                              ##安装新虚拟机，名为uc

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3dlaXhpbl80NDI5NzMwMw_size_16_color_FFFFFF_t_70 12]  
以后安装虚拟机可直接执行脚本，执行后坐下来喝茶就行了，等它自己安装完！

1.需要dhcp搭建 2.编写脚本和ks.cfg时要正确，避免错误
