RHEL7下PXE+FTP+Kickstart无人值守安装操作系统

1.配置yum源

vim /etc/yum.repos.d/development.repo

[development]

name=yum server

baseurl=file:///mnt

enabled=1

gpgcheck=0

2.挂载光盘

mount /dev/sr0 /mnt

3.安装相关软件包

yum install dhcp syslinux xinetd tftp-server

4.配置dhcp

vim /etc/dhcp/dhcpd.conf

5.添加内容

subnet 192.168.1.0 netmask 255.255.255.0 {

  range 192.168.1.91 192.168.1.120;                                                 //ip地址池

  option domain-name-servers 192.168.1.1;                                     //网管地址

  option domain-name "internal.example.org";

  option routers 192.168.1.1;                                                             //网关地址

  option broadcast-address 192.168.1.255;

  next-server 192.168.1.31;                                                              //ftp服务器地址

  filename "pxelinux.0";

  default-lease-time 600;

  max-lease-time 7200;

}

6.启动服务和开机自启动

systemctl start dhcpd.service

systemctl enable dhcpd.service

7.复制启动文件

cd /var/lib/tftpboot/                                                                                               #进入/var/lib/tftpboot/

cp /mnt/isolinux/initrd.img /var/lib/tftpboot                                                           #复制initrd.img到/var/lib/tftpboot目录下

cp /mnt/isolinux/vmlinuz /var/lib/tftpboot/                                                            #复制vmlinuz到/var/lib/tftpboot目录下

cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/                                              #复制pxelinux.0到/var/lib/tftpboot目录下

cp /mnt/isolinux/vesamenu.c32 /var/lib/tftpboot/                                                 #复制vesamenu.c32到/var/lib/tftpboot目录下

cp /mnt/isolinux/boot.msg /var/lib/tftpboot/                                                        #复制boot.msg到/var/lib/tftpboot目录下

cd /var/lib/tftpboot/                                                                                             #进入/var/lib/tftpboot目录下

mkdir pxelinux.cfg                                                                                             #在/var/lib/tftpboot目录下创建pxelinux.cfg目录

cd pxelinux.cfg/                                                                                                 #进入pxelinux.cfg目录下

cp /mnt/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default                     #复制isolinux.cfg到pxelinux.cfg目录下并命名为default

vim default                                                                                                       #在/var/lib/tftpboot/pxelinux.cfg目录下修改default文件

label PXE-linux

  menu label ^Install System from PXE-RHEL7.0

  menu default

  kernel vmlinuz

  append initrd=initrd.img ks=ftp://192.168.1.31/ks.cfg ksdevice=eno16777736 ip=dhcp quiet

8.配置tftp-server syslinux

vim /etc/xinetd.d/tftp

service tftp

{

        socket_type             = dgram

        protocol                = udp

        wait                    = yes

        user                    = root

        server                  = /usr/sbin/in.tftpd

        server_args             = -s /var/lib/tftpboot

        disable                 = no

        per_source              = 11

        cps                     = 100 2

        flags                   = IPv4

}

9.启动服务和开机自启动

systemctl start xinetd.service

systemctl enable xinetd.service

10.安装配置VSFTP

yum -y install vsftpd                       

cp -rf /mnt/* /var/ftp/pub/                    

11.启动服务

systemctl start vsftpd

systemctl enable vsftpd

12.无图形界面配置kickstart一键安装应答文件

vim /var/ftp/ks.cfg

#platform=x86, AMD64, 或 Intel EM64T

#version=DEVEL

# Install OS instead of upgrade

install

# Keyboard layouts

keyboard 'us'# Reboot after installation

reboot

# Root password

rootpw --iscrypted $1$FyasdJen$q2zUDfVq.ln1FmIlP8O/m0                       //root密码为7788521

# System timezone

timezone Asia/Shanghai

# Use network installation

url --url="ftp://192.168.1.31/pub"

# System language

# Firewall configuration

firewall --disabled

# Network information

# Disk partitioning information

part swap --asprimary --fstype="swap" --size=2048

part /boot --asprimary --fstype="xfs" --size=500

part / --asprimary --fstype="xfs" --grow --size=1

 

%packages

@base

 

%end

图形化系统可以安装Kickstart

1.安装Kickstart

yum -y install system-config-kickstart.noarch

2.启动Kickstart软件

system-config-kickstart

13.修改SELinux状态

vim /etc/sysconfig/selinux

SELINUX=disabled

14.开放防火墙服务和端口

firewall-cmd --permanent --add-service=dhcp

firewall-cmd --permanent --add-service=vsftpd

firewall-cmd --permanent --add-port=69/udp

firewall-cmd --permanent --add-port=111/tcp

firewall-cmd --permanent --add-port=111/udp

firewall-cmd --permanent --add-port=20048/tcp

firewall-cmd --permanent --add-port=20048/udp

firewall-cmd --reload
