Kickstart deploying multiple operating systems at the same time

RHEL7 Kickstart deploying multiple operating systems simultaneously

#在日常企业运维环境中, it is inevitable to encounter the use of multiple Linux operating systems, the previous kickstart can only install a Linux version of the system, if you need to install a different version of the Linux system every day, how to do? So here's how to deploy different versions of the Linux operating system at the same time using kickstart, and deploy the Rhel6,rhel7,kickstart RHEL7 system at the same time;

#配置yum源

Vim/etc/yum.repos.d/server.repo

[Base]

Name=rhel

Baseurl=file:///mnt

Enabled=1

Gpgcheck=0

#挂在光盘

Mount/dev/cdrom/mnt

#安装配置DHCP

Yum-y Install DHCP

Cp/usr/share/doc/dhcp-4.2.5/dhcpd.conf.example/etc/dhcp/dhcpd.conf

vim/etc/dhcp/dhcpd.conf#dhcp根据实际环境配置

Subnet 192.168.1.0 netmask 255.255.255.0 {

Range 192.168.1.100 192.168.1.200;

Option Domain-name-servers server.example.com;

Option Domain-name "8.8.8.8";

Option routers 192.168.1.254;

Option broadcast-address 192.168.1.255;

Next-server 192.168.1.89;

FileName "pxelinux.0";

Default-lease-time 60000;

Max-lease-time 720000;

}

Systemctl Restart Dhcpd.service#启动dhcp服务

Systemctl Enable Dhcpd.service#随下次开机自动启动该服务

#安装配置tftp-server Syslinux

Yum-y Install Syslinux Tftp-server

Vim/etc/xinetd.d/tftp

Disable=no#将yes修改no

Systemctl Restart Xinetd.service

Systemctl Enable Xinetd.service

#复制多系统启动文件

Cd/var/lib/tftpboot

mkdir rhel6 rhel7#因为是多系统引导安装所以创建两个不同版本的文件夹, store different boot files

CD Rhel7#rhel7文件夹里面存放rhel7的引导文件, need to manually mount RHEL7 system disc copy boot file

Cp/mnt/isolinux/init.img. #复制到当前

Cp/mnt/isolinux/vmlinuz.

Cd.. #放回上一级目录

CD rhel6#rhel6文件夹里面存放rhel6的引导文件, need to manually mount Rhel6 system disc copy copy file

Cp/mnt/isolinux/init.img.

Cp/mnt/isolinux/vmlinuz.

Cd.. #放回上一级目录

mkdir pxelinux.cfg

CD pxelinux.cfg

Cp/mnt/isolinux/isolinux.cfg./default#随便使用哪个系统版本的引导菜单都可以使用, copy to change the name to the default to make the corresponding changes

Vim default#编辑default文件

Label RHEL7

Kernel rhel7/vmlinuz#刚才创建了对应系统版本文件夹, all Vmlinuz front plus RHEL7

Append initrd=rhel7/initrd.img inst.ks=nfs:192.168.1.89:/rhel7/ks.cfg#initrd. IMG in front of the same plus RHEL7

Label Rhel6

Kernel Rhel6/vmlinuz

Append initrd=rhel6/initrd.img ks=nfs:192.168.1.89:/rhel6/ks.cfg#rhel6的ks命令不一样, there is no inst in front.

Cd.. #返回上一级目录

Vim boot.msg#创建一个安装提示文件

+++++++++++++++++++++++++++++++++++++++++++++++++++++++

++++++please Enter rhel6 and rhel6 install system++++++

#安装配置NFS

Yum-y Install nfs*#系统默认没有安装则安装nfs服务

Mkdir/rhel6/rhel7#创建不同目录存放系统对应版本的安装文件

Cd/rhel6

Nohup cp-a/mnt/*. &#挂载rhel6光盘, copying system files in the background

Cd/rhel7

Nohup cp-a/mnt/*. &#挂载rhel7光盘, copying system files in the background

Vim/etc/exports#nfs共享不同版本系统的文件

/rhel6192.168.1.0/24 (Rw,sync)

/rhel7192.168.1.0/24 (Rw,sync)

Systemctl Restart Nfs-server.service

Systemctl Enable Nfs-server.service
