建个PXE服务器，通过PXE服务器安装Linux还是很方便的。

  • 安装
sudo yum -y install syslinux xinetd tftp-server

mkdir /home/data/tftpboot/pxelinux.cfg

cp -rf /usr/share/syslinux/pxelinux.0 /home/data/tftpboot

sudo chcon -ht tftpdir_rw_t /home/data/tftpboot
  • 启动TFTP

编辑/etc/xinetd.d/tftp

disable = no #yes改成no

        server_args             = -s /var/lib/tftpboot

改成

        server_args             = -s /home/data/tftpboot

sudo systemctl enable xinetd
sudo systemctl start xinetd
  • 编辑/home/data/tftpboot/pxelinux.cfg/default文档

内容如下：

#default vesamenu.c32
timeout 30
#default menu.c32
#prompt 0
default vesamenu.c32
prompt 1

sudo systemctl restart dhcpd
  • 防火墙
firewall-cmd --permanent --add-service=tftp
