PXE 装机服务器的搭建

一、环境准备  
\[root@pxesvr ~\]\# ifconfig eth0 | grep "inet "  
inet 192.168.4.5 netmask 255.255.255.0 broadcast 192.168.4.255  
\[root@pxesvr ~\]\# hostname  
pxesvr.tedu.cn  
\[root@pxesvr ~\]\# cat /etc/resolv.conf  
\# Generated by NetworkManager  
search tedu.cn  
nameserver 192.168.4.5  
\[root@pxesvr ~\]\# grep SELINUX= /etc/sysconfig/selinux  
\# SELINUX= can take one of these three values:  
SELINUX=disabled  
\[root@pxesvr ~\]\# setenforce 0  
\[root@pxesvr ~\]\# getenforce  
Permissive  
\[root@pxesvr ~\]\# firewall-cmd --get-default-zone  
public  
\[root@pxesvr ~\]\# firewall-cmd --set-default-zone=trusted  
success  
\[root@pxesvr ~\]\# yum-config-manager --add http://192.168.4.254/rh7dvd/  
\[root@pxesvr ~\]\# echo "gpgcheck=0" >> /etc/yum.repos.d/192.168.4.254\_rh7dvd\_.repo  
二、PXE服务部署  
1. 配置HTTP，实现YUM源  
\[root@pxesvr ~\]\# yum clean all  
\[root@pxesvr ~\]\# rpm -q httpd  
\[root@pxesvr ~\]\# yum list httpd  
\[root@pxesvr ~\]\# yum -y install httpd  
把RHEL7.2 dvd光盘放入光驱  
\[root@pxesvr ~\]\# umount /dev/cdrom  
\[root@pxesvr ~\]\# mount /dev/cdrom /mnt/  
\[root@pxesvr ~\]\# mkdir /var/www/html/rh7dvd  
\[root@pxesvr ~\]\# cp -rfp /mnt/\* /var/www/html/rh7dvd/  
\[root@pxesvr ~\]\# du -sh /var/www/html/rh7dvd/ /mnt/  
3.9G /var/www/html/rh7dvd/  
3.9G /mnt/  
\[root@pxesvr ~\]\# systemctl restart httpd  
\[root@pxesvr ~\]\# systemctl enable httpd  
\[root@pxesvr ~\]\# netstat -anptu | grep httpd  
tcp6 0 0 :::80 :::\* LISTEN 6061/httpd  
测试：  
http://192.168.4.5/rh7dvd/  
2. 配置DHCP服务器  
\[root@pxesvr ~\]\# rpm -q dhcp  
\[root@pxesvr ~\]\# yum list dhcp  
\[root@pxesvr ~\]\# yum -y install dhcp  
\[root@pxesvr ~\]\# cat /etc/dhcp/dhcpd.conf  
subnet 192.168.4.0 netmask 255.255.255.0 \{  
range 192.168.4.10 192.168.4.20;  
option domain-name-servers 192.168.4.5;  
option domain-name "tedu.cn";  
next-server 192.168.4.5;  
filename "pxelinux.0";  
\}  
\[root@pxesvr ~\]\# systemctl restart dhcpd  
\[root@pxesvr ~\]\# systemctl enable dhcpd  
\[root@pxesvr ~\]\# netstat -anptu | grep dhcpd  
udp 0 0 0.0.0.0:57024 0.0.0.0:\* 6963/dhcpd  
udp 0 0 0.0.0.0:67 0.0.0.0:\* 6963/dhcpd  
udp6 0 0 :::21554 :::\* 6963/dhcpd  
3. 配置TFTP服务器  
\[root@pxesvr ~\]\# rpm -q tftp-server  
\[root@pxesvr ~\]\# yum list tftp-server  
\[root@pxesvr ~\]\# yum -y install tftp-server  
\[root@pxesvr ~\]\# systemctl restart tftp  
\[root@pxesvr ~\]\# systemctl enable tftp  
\[root@pxesvr ~\]\# netstat -anptu | grep :69  
udp6 0 0 :::69 :::\* 1/systemd  
4. 配置启动文件  
\[root@pxesvr ~\]\# rpm -q syslinux  
\[root@pxesvr ~\]\# yum list syslinux  
\[root@pxesvr ~\]\# yum -y install syslinux  
\[root@pxesvr ~\]\# rpm -ql syslinux |grep pxelinux.0  
\[root@pxesvr ~\]\# cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/  
\[root@pxesvr ~\]\# mkdir /var/lib/tftpboot/rhel7  
\[root@pxesvr ~\]\# cd /var/www/html/rh7dvd/isolinux/  
\[root@pxesvr isolinux\]\# cp initrd.img vmlinuz /var/lib/tftpboot/rhel7/  
\[root@pxesvr isolinux\]\# cp vesamenu.c32 splash.png /var/lib/tftpboot/  
\[root@pxesvr isolinux\]\# mkdir /var/lib/tftpboot/pxelinux.cfg/  
\[root@pxesvr isolinux\]\# cp isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default  
\[root@pxesvr isolinux\]\# ls -R /var/lib/tftpboot/  
/var/lib/tftpboot/:  
pxelinux.0 pxelinux.cfg rhel7 splash.png vesamenu.c32

/var/lib/tftpboot/pxelinux.cfg:  
default

/var/lib/tftpboot/rhel7:  
initrd.img vmlinuz  
\[root@pxesvr isolinux\]\# vim /var/lib/tftpboot/pxelinux.cfg/default  
...  
61 label linux  
62 menu label ^Install Red Hat Enterprise Linux 7.2  
63 kernel rhel7/vmlinuz  
64 append initrd=rhel7/initrd.img inst.stage2=http://192.168.4.5/rh7dvd quiet  
5. 检验pxe装机服务器

6. 生成Kiskstart文件  
\[root@pxesvr ~\]\# rpm -q system-config-kickstart  
\[root@pxesvr ~\]\# yum list system-config-kickstart  
\[root@pxesvr ~\]\# yum -y install system-config-kickstart  
\[root@pxesvr ~\]\# system-config-kickstart  
具体文件内容参考FTP ks-rhel7.cfg

7.调整default文件  
\[root@pxesvr ~\]\# vim /var/lib/tftpboot/pxelinux.cfg/default  
...  
61 label linux  
62 menu label ^Install Red Hat Enterprise Linux 7.2  
63 menu default  
64 kernel rhel7/vmlinuz  
65 append initrd=rhel7/initrd.img ks=http://192.168.4.5/ks/ks-rhel7.cfg

8. 测试

三、增加rhel6.7的安装源  
1. 准备rhel6.7源  
在光驱中放入rhel6.7 ios文件  
\[root@pxesvr ~\]\# umount /dev/cdrom  
\[root@pxesvr ~\]\# mount /dev/cdrom /mnt/  
\[root@pxesvr ~\]\# mkdir /var/www/html/rh6dvd  
\[root@pxesvr ~\]\# cp -rfp /mnt/\* /var/www/html/rh6dvd/  
2. 添加rhel6的内核文件，初始化文件  
\[root@pxesvr ~\]\# cd /var/lib/tftpboot/  
\[root@pxesvr tftpboot\]\# mkdir rhel6  
\[root@pxesvr tftpboot\]\# cd /var/www/html/rh6dvd/isolinux/  
\[root@pxesvr isolinux\]\# cp vmlinuz initrd.img /var/lib/tftpboot/rhel6/  
3. 修改default文件  
\[root@pxesvr isolinux\]\# vim /var/lib/tftpboot/pxelinux.cfg/default  
...  
61 label rhel6  
62 menu label Install Red ^Hat Enterprise Linux 6.7  
63 kernel rhel6/vmlinuz  
64 append initrd=rhel6/initrd.img ks=http://192.168.4.5/ks/ks-rhel6.cfg  
65  
66 label rhel7  
67 menu label ^Install Red Hat Enterprise Linux 7.2  
68 menu default  
69 kernel rhel7/vmlinuz  
70 append initrd=rhel7/initrd.img ks=http://192.168.4.5/ks/ks-rhel7.cfg  
4. 生成ks-rhel6.cfg文件  
\[root@pxesvr isolinux\]\# cd /var/www/html/ks/  
\[root@pxesvr ks\]\# cp -p ks-rhel7.cfg ks-rhel6.cfg  
\[root@pxesvr ks\]\# vim ks-rhel6.cfg  
...  
12 url --url="http://192.168.4.5/rh6dvd"  
...  
36 part /boot --fstype="ext4" --size=200  
37 part / --fstype="ext4" --size=10000  
38 part swap --fstype="swap" --size=8192  
39  
40 %post --interpreter=/bin/bash  
41 rm -rf /etc/yum.repos.d/\*.conf  
42 echo "\[rhel6\]  
43 name=rhel6.7  
44 baseurl=http://192.168.4.5/rh6dvd  
45 enabled=1  
46 gpgcheck=0" > /etc/yum.repos.d/rhel6.repo  
47 yum clean all  
5. 测试
