1、关闭防火墙和selinux systemctl stop firewalld systemctl disable firewalldsetenforce 02、配置静态ip
需要在dhcp里面填写tftp配置所以需要固定ip
二、dhcp安装配置
作用给客户端提供ip地址并告诉客户端tftp地址
$ yum install -y dhcp#默认dhcp配置文件为空
$ cp /usr/share/doc/dhcp-4.2.5/dhcpd.conf.example /etc/dhcp/dhcpd.conf#修改dhcp配置仅列出修改部分未修改部分保持默认即可
next-server 172.13.11.222; #tftp-server地址
filename pxelinux.0; #引导文件名称subnet 172.13.11.0 netmask 255.255.255.0 {range 172.13.11.200 172.13.11.222;option domain-name-servers 114.114.114.114;option domain-name example.com;option routers 172.13.11.254;option broadcast-address 172.13.11.255;default-lease-time 600;max-lease-time 7200;
}$ systemctl start dhcpd systemctl enable dhcpd三、安装tftp-server和http
$ yum install -y tftp-server xinted $ cat /etc/xinetd.d/tftp
disable no #将yes改为no$ systemctl start xinetd systemctl enable xinetd$ yum install httpd -y
$ systemctl start httpd systemctl enable httpd
$ mkdir /var/www/html/pub/ #用来存放系统文件
$ mkdir /var/www/html/ks/ #用来存放ks自动应答文件四、获取系统和引导文件
4.1、准备文件
yum install syslinux -ymkdir /var/lib/tftpboot/pxelinux.cfg
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/pxelinux.cfg/default#挂载光盘文件
$ cat /etc/fstab
/dev/cdrom /var/www/html/pub iso9660 defaults 0 0$ df -h

$ cat /var/lib/tftpboot/pxelinux.cfg/defaultlabel minimenu label ^Install mini CentOS 7.6menu defaultkernel vmlinuzappend initrdinitrd.img kshttp://10.139.8.222/ks/ks.cfg五、准备ks.cfg自动应答文件
