对Centos的自动安装的补充

Posted 2020-09-21 KaShing

上一篇博文：http://www.cnblogs.com/hjc4025/p/6918323.html

这篇文章是对之前博文的一点扩展和补充：

这里主要是在之前的基础上添加了一些自己制作好的程序，还有安装openssh7.5版本，直接全部包含在镜像中，并且设置一些自启动程序、DNS、还有计划任务之类的，都是利用ks.cfg文件的post字段后面定义的脚本实现的，在post的阶段中使用--nochroot 表示可以使用任何目录，而本阶段中的 / （根目录）是会自动挂在到/mnt/sysimage下，下面请看我的ks.cfg文件：

#platform=x86, AMD64, or Intel EM64T 
# Firewall configuration 
firewall --disabled 
# Install OS instead of upgrade 
install 
# Use CDROM installation media 
cdrom 
# Root password default is "redhat" 
rootpw --iscrypted $1$n5Jfcfwa$//2gZpFMJypdiXEF8ld6O.
# System authorization information 
auth  --useshadow  --passalgo=md5
# Use text mode install 
text 
firstboot --disable 
# System keyboard 
keyboard us 
# System language

# SELinux configuration 
selinux --disabled 
# Do not configure the X Window System 
skipx 
# Installation logging level 
logging --level=info
# Reboot after installation 
reboot 
# System timezone

# Network information

# System bootloader configuration

 这个里面包括使用了最新的openssh 7.5 还有 openssl1.01t 版本，里面也有一些走过的坑。。不过最终还是做出来了
