PXE 通过网卡安装系统 预安装
流程
pxe-server端
hostnamectl set-hostname pxe-server.example.com
yum源更改 clean all repolist
yum install dhcp
cp /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example /etc/dhcp/dhcpd.conf
vim /etc/dhcp/dhcpd.conf
option domain-name "westos.com";
option domain-name-servers 172.25.254.250;
subnet 172.25.254.0 netmask 255.255.255.0 {
range 172.25.254.1 172.25.254.100;
option routers 172.25.254.250;
next-server 172.25.254.212;
filename "pxelinux.0";
}
systemctl restart dhcpd
yum install syslinux-4.05 tftp-server
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot
vim /etc/xinetd.d/tftp
disable = no
systemctl restart xinetd
systemctl stop firewalld
vim /etc/dhcp/dhcpd.conf
next-server 172.25.254.212;
filename "pxelinux.0";
将启动文件复制到该目录下
[root@pxe-server isolinux]# ls
boot.cat grub.conf isolinux.bin memtest TRANS.TBL vesamenu.c32
boot.msg initrd.img isolinux.cfg splash.png upgrade.img vmlinuz
[root@pxe-server isolinux]# cp * /var/lib/tftpboot/
[root@pxe-server isolinux]# cd /var/lib/tftpboot/
[root@pxe-server tftpboot]# ls
boot.cat grub.conf isolinux.bin memtest splash.png upgrade.img vmlinuz
boot.msg initrd.img isolinux.cfg pxelinux.0 TRANS.TBL vesamenu.c32
[root@pxe-server tftpboot]# mkdir pxelinux.cfg
[root@pxe-server tftpboot]# ls
boot.cat grub.conf isolinux.bin memtest pxelinux.cfg TRANS.TBL vesamenu.c32
boot.msg initrd.img isolinux.cfg pxelinux.0 splash.png upgrade.img vmlinuz
[root@pxe-server tftpboot]# cp isolinux.cfg pxelinux.cfg/
[root@pxe-server tftpboot]# cd pxelinux.cfg/
[root@pxe-server pxelinux.cfg]# ls
isolinux.cfg
[root@pxe-server pxelinux.cfg]# mv isolinux.cfg default
yum install system-config-kickstart httpd -y
systemctl start httpd
system-config-kickstart
然后在后面加入
%packages
@base
@console-internet
@core
@fonts
@gnome-desktop
@input-methods
@internet-browser
@java-platform
@network-file-system-client
@perl-runtime
@virtualization-client
@virtualization-hypervisor
@virtualization-platform
@virtualization-tools
@x11
chrony
lftp
mtools
pax
vnc
%end
%post
cat > /etc/yum.repos.d/yum.repo <<EOF
[rhel7.3]
name=rhel7.3
baseurl=http://172.25.254.250/rhel7.3/x86_64/dvd
gpgcheck=0
EOF
%endi
cp ks.cfg /var/www/html/
ksvalidator ks.cfg 检测正确性
然后配置default
timeout 60 设置默认等待时间
label linux
menu label ^Install Red Hat 7.3
menu default
kernel vmlinuz
append initrd=initrd.img repo=http://172.25.254.250/rhel7.3/x86_64/dvd ks=http://172.25.254.212/ks.cfg
上面是默认选项和使用脚本安装
systemctl restart xinetd.service
就可以了 然后装机的时候一定要有网线
