1、创建ISO镜像存放路径，挂载ISO
[[email protected] Desktop]# mkdir /dvd
[[email protected] Desktop]# mkdir /root/isos/
[[email protected] Desktop]#echo "/root/isos/rhel-server-7.1-x86_64-dvd.iso /dvd iso9660 loop 0 0" >> /etc/fstab
[[email protected] Desktop]#mount -a
2、配置网卡地址
cat > /etc/sysconfig/network-scripts/ifcfg-br0 <<EOF
NAME=br0
DEVICE=br0
ONBOOT=yes
BOOTPROTO=none
TYPE=Ethernet
IPADDR=192.168.1.254
PREFIX=255.255.255.0
EOF
3、配置Yum Client
4、安装需要的软件包并关闭防火墙
yum install tftp-server syslinux nfs-* dhcp gpm bash-com* -y
systemctl stop firewalld
systemctl disable firewalld
5、安装DHCP
cat > /etc/dhcp/dhcpd.conf << EOF
filename "pxelinux.0";
next-server 192.168.1.254;
subnet 192.168.1.0 netmask 255.255.255.0 {
range 192.168.1.1 192.168.1.250;
option domain-name-servers 192.168.1.254;
option domain-name "redhat.com";
option routers 192.168.1.254;
default-lease-time 600;
max-lease-time 7200;
}
EOF
6、打开DHCP并重启
systemctl enable dhcpd
systemctl start dhcpd
7、配置TFTP服务
配置TFTP，使/var/lib/tftpboot/目录下生成如下目录树
[[email protected] ~]# cd /var/lib/tftpboot/
[[email protected] tftpboot]# mkdir pxelinux.cfg
[[email protected] tftpboot]# cp /dvd/isolinux/* /var/lib/tftpboot/
[[email protected] tftpboot]# cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
[[email protected] tftpboot]# mv isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default
8、更改/var/lib/tftpboot/ pxelinux.cfg/default文件中的如下部分
#原有配置:
label linux
menu label ^Install Red Hat Enterprise Linux 7.1
kernel vmlinuz
append initrd=initrd.img inst.stage2=hd:LABEL=RHEL-7.1\x20Server.x86_64 quiet
#最终配置
label linux
menu label ^Install Red Hat Enterprise Linux 7.1
kernel vmlinuz
append initrd=initrd.img inst.stage2=nfs://192.168.1.254/dvd
9、开启服务并重启
systemctl enable xinetd
systemctl enable tftp.socket
systemctl start xinetd
systemctl start tftp.socket
10、生成配置
echo "/dvd *(ro,sync)" > /etc/exports
11、重启nfs并重新启动系统
systemctl enable nfs-server
systemctl start nfs-server
reboot
