pxe+kickstart简单搭建

pxe+kickstart简单搭建，我这里写得比较粗略，不过比较容易看懂
[root@ha1 ~]# yum -y install tftp tftp-server httpd syslinux dhcp
复制dhcp样例配置文件到dhcp的配置文件目录下
[root@ha1 dhcp]# cp /usr/share/doc/dhcp-4.1.1/dhcpd.conf.sample /etc/dhcp/dhcpd.conf
cp: overwrite `/etc/dhcp/dhcpd.conf'? y
[root@ha1 dhcp]# vim dhcpd.conf
配置文件内容如下
option domain-name "example.org";
option domain-name-servers ns1.example.org, ns2.example.org;
default-lease-time 600;
max-lease-time 7200;
log-facility local7;
主要添加以下内容，其他内容视实际情况而定
subnet 172.16.0.0 netmask 255.255.0.0 {
range 172.16.6.99 172.16.6.199;
#option routers 172.16.0.1; 网关
option routers 172.16.6.20; #vm 调整为
next-server 172.16.6.20;
filename "pxelinux.0";
}
修改xinetd超级守护线程的配置文件
[root@ha1 dhcp]# 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 = no #默认值为yes，把yes改为no
per_source = 11
cps = 100 2
flags = IPv4
}
[root@ha1 dhcp]# service xinetd restart
Stopping xinetd: [FAILED]
Starting xinetd: [ OK ]
[root@ha1 dhcp]# ls /usr/share/syslinux
复制pxelinux.0文件到/var/lib/tftpboot/目录下
[root@ha1 dhcp]# cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
[root@ha1 dhcp]# ls /var/lib/tftpboot/
pxelinux.0
测试tftp服务是否正常

[root@ha1 dhcp]# cd /tmp/
[root@ha1 tmp]# tftp 172.16.6.20
tftp> get pxelinux.0 #使用get下载pxelinux.0文件
tftp> quit
[root@ha1 tmp]# ls #查看是否能下载pxelinux.0文件
pulse-KLoEGFAUVElg pxelinux.0
[root@ha1 tmp]# cd ~
[root@ha1 ~]# mkdir -pv /media/cdrom
mkdir: created directory `/media/cdrom
在vm虚拟机上挂载centos6.6.iso镜像
[root@ha1 ~]# mount -r /dev/cdrom /media/cdrom/ #把系统镜像文件挂载到centos6.6.iso镜像
[root@ha1 ~]# cd /media/cdrom/
[root@ha1 cdrom]# ls
