配置pxe自动化安装centos系统

一、配置kickstart应答文件
要想配置kickstart ，首先要配置个本地yum源，要不然用system-config-kickstart时选不上包。而且，centos6的yum 源的名字一定是[base],要不然会报:
Package selection is disabled due to problems downloading package information.
centos7要把仓库名称更改为development
[development]
name=base
baseurl=file:///mnt/
利用安装system-config-kickstart
yum -y system-config-kickstart
如果不能启动，用xshell,连接，左键属性，隧道勾选转发X11连接到(X)，选择Xmanager(M)
安装httpd服务，执行system-config-kickstart时会用到httpd服务来对安装文件目录进行配置
yum -y install httpd
mkdir /var/www/html/7/x86_64 -p
mount /dev/sr0 /var/www/html/7/x86_64
systemctl start httpd




二、设置dhcp服务器
rpm -ivh /var/www/html/6/Packages/dhcp-4.1.1-60.P1.el6.centos.x86_64.rpm
vim /etc/dhcp/dhcpd.conf
option domain-name "magedu.com"; ping自动补全
option domain-name-servers 192.168.0.1,8.8.8.8; DNS1DNS2
default-lease-time 86400; 默认租期
max-lease-time 86400; 客户端可获取的最长租期
subnet 192.168.100.0 netmask 255.255.255.0 { 网段及掩码
range 192.168.100.1 192.168.100.200; 分配的ip地址
option routers 192.168.100.1; 分配的网关地址
}
service dhcpd start
vim /var/lib/dhcpd/dhcpd.leases 查看分配记录
三、设置tftp服务器
yum -y install tftp-server
vim /etc/xinetd.d/tftp
disable = no
service xinetd start
ss -unlp | grep xinetd 查看是否监听udp的69端口
tftp共享文件目录在/var/lib/tftpboot
四、准备pxe安装centos系统
mkdir /var/lib/tftpboot/pxelinux.cfg/
cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/
cd /misc/cd/images/pxeboot/
cp vmlinuz initrd.img /var/lib/tftpboot
Cd /misc/cd/isolinux/
cp boot.msg vesamenu.c32 splash.jpg /var/lib/tftpboot

vim /var/lib/tftpboot/pxelinux.cfg/default
default vesamenu.c32 指定菜单风格
#prompt 1
timeout 600
display boot.msg
menu background splash.jpg
menu title Welcome to wang CentOS 6
