6-3pxe应用入门

172.18.253.208 yum　install dhcp tftp-server tftp syslinux vsftpd---配置成一个dhcp server 此时还需要一个kickstart文件，视频中是从服务器获取 centos 6改IP地址使用setup命令192.168.10.16 255.255.255.0 网关192.168.10.1 service network restart ifconfig---查看ip地址有没有配置上去 ssh root@192.168.10.16 vim /etc/ssh/sshd_config UseDNS no---这里改为no service sshd reload

先配置dhcp服务 cd /etc/dhcp cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample ./dhcpd.conf vim dhcpd.conf option domain-name "mageedu.com"; option domain-name-servers 172.18.0.1;

default-lease-time 600; max-lease-time 7200;

log-facility local7;

subnet 192.168.10.0 netmask 255.255.255.224 { range 192.168.10.151 192.168.10.160; filename "pxelinux.0"; next-server 192.168.10.16; }

service dhcpd configtest service dhcpd start ss -unl---67端口 chkconfig dhcpd on---开机自动启动

接下来准备tftp服务 chkconfig tftp on，也可以编辑配置文件 vim /etc/xinetd.d/tftp service tftp { socket_type = dgram protocol = udp wait = yes user = root server = /usr/sbin/in.tftpd server_args = -s /var/lib/tftpboot disable = yes---这里改为no per_source = 11 cps = 100 2 flags = IPv4 } service xinetd restart chkconfig xinetd on ss -unl---69号端口 cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/ cd /tmp tftp 192.168.10.16---这里是测试tftp服务是否正常 get pxelinux.0

接下来就该复制光盘中的文件了，虚拟机挂载的是物理机中的光盘 mkdir /media/cdrom mount -r /dev/cdrom /media/cdrom ls /media/cdrom cp /media/cdrom/images/pxeboot/{vmlinuz,initrd.img} /var/lib/tftpboot/ cp /media/cdrom/isolinux/{boot.msg,vesamenu.c32,splash.jpg} /var/lib/tftpboot mkdir /var/lib/tftpboot/pxelinux.cfg/ cp /media/cdrom/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default chmod +w /var/lib/tftpboot/pxelinux.cfg/default vim /var/lib/tftpboot/pxelinux.cfg/default default vesamenu.c32

timeout 600

display boot.msg

接下来需要准备yum仓库 mkdir /var/ftp/pub/centos mount --bind /media/cdrom/ /var/ftp/pub/cnetos---这是绑定的方式 vim centos6.cfg---kickstart文件 firewall --disabled
