自建DHCP TFTP服务 用PXE启动实现无人值守安装Centos6
1、安装DHCP TFTP
yum -y install dhcp tftp-server tftp
2、配置DHCP文件
cat > /etc/dhcp/dhcpd.conf << EOF # option domain-name "dwhd.org"; #设置DHCP的DNS option domain-name-servers 172.16.0.1,114.114.114.114; #设置DHCP 分配出去的IP超时时间 单位秒 default-lease-time 86440; #设置DHCPlease-time时间 单位秒 max-lease-time 100000; log-facility local7; #设置DHCP的 IP 和掩码 subnet 192.168.1.0 netmask 255.255.255.0 { #设置DHCP对外分配IP段 range 192.168.1.50 192.168.1.70; #设置路由IP option routers 192.168.1.1; #下面的4行是根据mac分配指定IP host Centos7 { hardware ethernet 00:0c:29:ba:3c:76; fixed-address 192.168.1.65; } #如果是PXE网卡来获取到了IP 告诉网卡下一步联系的服务器IP 192.168.1.120 next-server 192.168.1.120; #PXE网卡联系了服务器之后告诉它应该去获取文件pxelinux.0 filename "pxelinux.0"; } EOF
3、检测dhcp配置和启动dhcp
[root@localhost pxelinux.cfg]# service dhcpd configtest Syntax: OK #检测dhcp配置,如果出现Syntax: OK则说明配置OK了 #启动DHCP服务 service dhcpd start
4、设置TFTP开机启动
chkconfig tftp on[/bash] [bash highlight="9,10"][root@localhost ~]# netstat -unl Active Internet connections (only servers) Proto Recv-Q Send-Q Local Address Foreign Address State udp 0 0 0.0.0.0:1005 0.0.0.0:* udp 0 0 0.0.0.0:111 0.0.0.0:* udp 0 0 0.0.0.0:631 0.0.0.0:* udp 0 0 0.0.0.0:776 0.0.0.0:* udp 0 0 0.0.0.0:48819 0.0.0.0:* udp 0 0 0.0.0.0:67 0.0.0.0:* udp 0 0 0.0.0.0:69 0.0.0.0:* udp 0 0 :::1005 :::* udp 0 0 :::111 :::* udp 0 0 :::42066 :::* ##看看 67 69端口是否被监听了,如果是的就说明好了
开始为PXE启动做准备,由于我在当前Windows物理机上架设了FTP服务,所以我这里就直接用FTP服务器做源了
5、下载必要的文件到TFTP目录
ftpurl="ftp://lookback:lookback@192.168.1.20/centos/6/x86_64/base/" tftpdir="/var/lib/tftpboot/" for I in vmlinuz initrd.img; do wget -O ${tftpdir}$I ${ftpurl}images/pxeboot/$I;done for II in splash.jpg vesamenu.c32 boot.msg isolinux.cfg; do [ "$II" == "isolinux.cfg" ] && wget -O ${tftpdir}default ${ftpurl}/isolinux/$II wget -O ${tftpdir}$II ${ftpurl}/isolinux/$II done #安装syslinux yum -y install syslinux #复制pxelinux.0到TFTP目录下 cp $(rpm -ql syslinux | grep ‘\bpxelinux.0‘) /var/lib/tftpboot/ #最后核对下文件 tree /var/lib/tftpboot/ #结果和下图一样就对了
6、制作kf.cfg文件 用于自动化安装
下面是我自己制作的ks.cfg,可根据自己的需求做改动 root密码是centos6,这个文件存放的位置需要在系统安装的时候被获取到,我这里存放在我物理机上的FTP下

现在来修改下PXE启动后引导菜单
vi /var/lib/tftpboot/pxelinux.cfg/default
