使用vmware測試PXE批量安裝服務器的詳細過程
一、準備階段
1、準備環境
Vmware workstation
Centos7一臺做pxe-server
地址:192.168.138.5
子網掩碼:255.255.255.0
網關:192.168.138.2
關閉selinux和防火墻
2、安裝方式
Kickstart安裝。 Kickstart是一種無人值守的安裝方式。它的工作原理是在安裝過程中記錄典型的需要人工幹預填寫的各種參數,並生成一個名為ks.cfg的文件。安裝程序首先會去查找Kickstart生成的文件,如果找到合適的參數,就采用這些參數;安裝程序會根據ks.cfg中的設置重啟系統,並結束安裝。
3、網卡配置
網卡選擇hostonly模式,取消hostonly模式的dhcp功能。
二、安裝階段
因為後面要用到system-config-kickstart工具生成ks文件,它必須依賴於X Windows,所以我們要提前安裝好桌面環境。
yum-y groupinstall ‘X Window System’
yum-y groupinstall ‘GNOME Desktop Environment’
1、安裝httpd
需要http的環境存放系統鏡像文件和ks文件,所以先安裝http
yum install httpd
Systemctl start httpd
訪問http://192.168.138.5
配置yum
mount /dev/cdrom /mnt
cd /mnt
2、安裝tftp-server
yum-y install tftp-server
修改/etc/xinetd.d/tftp,將disable的值由yes變為no
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 }
重啟xinetd進程,若沒有xinetd則需要yum安裝
systemctl restart xinetd.service
新建tftpboot文件夾
mkdir -p /var/lib/tftpboot
3、復制pxe文件
安裝syslinux,並復制pxelinux.0文件到/var/lib/tftpboot中
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot
新建/var/www/html/cdrom,並掛載
Mount /dev/cdrom /var/www/html/cdrom
yum源配置
將光盤上的initrd.img和vmlinuxz復制到/var/lib/tftpboot中
cp /var/www/html/cdrom/images/pxeboot/initrd.img /var/lib/tftpboot
cp /var/www/html/cdrom/images/pxeboot/vmlinuz /var/lib/tftpboot
cp /var/www/html/cdrom/isolinux/boot.msg /var/lib/tftpboot
在tftpboot中新建一個pxelinux.cfg目錄
mkdir pxelinux.cfg
將cdrom目錄中的isolinux.cfg復制到pxelinux.cfg目錄中,同時更改文件名稱為default
cp /var/www/html/cdrom/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
編輯default文件
配置如下
default vesamenu.c32
timeout 6000
display boot.msg
#Clear the screen when exiting the menu, instead of leaving the menu displayed.
#For vesamenu, this means the graphical background is still displayed without
#the menu itself for as long as the screen remains in graphics mode.

重啟httpd服務
cp /var/www/html/cdrom/isolinux/vesamenu.c32 /var/lib/tftpboot/
4、安裝dhcp服務
yum –y install dhcp
cp /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example /etc/dhcp/dhcpd.conf
修改dhcpd.conf
next-server 192.168.138.5; ——————本機地址,作為ks服務器的地址
filename “pxelinux.0”;
subnet 192.168.138.0 netmask 255.255.255.0 {
range 192.168.138.10 192.168.138.50; ———–分配的地址池
option routers 192.168.138.5;
option subnet-mask 255.255.255.0;
option domain-name-servers 192.168.138.5;
default-lease-time 86400;
max-lease-time 86400;
}
配置好後啟動dhcp
service dhcpd start
三、安裝kickstart自動安裝工具
Yum直接安裝
yum -y install system-config-kickstart
在桌面環境下啟動Kickstart
system-config-kickstart
分區自己看情況分配,usr目錄盡量分配4G以上
安裝包選擇桌面版可安裝圖形版,自行選擇。如果該步驟報錯,看yum配置
下面兩項默認即可
配置好後file–>save
保存到該目錄下,查看ks.cfg文件
#platform=x86, AMD64, or Intel EM64T
#version=DEVEL
#Install OS instead of upgrade

#Keyboard layouts

#Root password

四、在客戶主機上測試
新建一個虛擬機,進pxe選擇從網絡加載dhcp,然後就直接自動安裝即可
在 /var/lib/dhcpd/dhcpd.leases裡可以看見新增機器分配的ip地址等信息
五、相關服務
systemctl start httpd
systemctl enable httpd
systemctl start dhcpd
systemctl enable dhcpd
systemctl start xinetd
