pxe无人值守安装linux
简要介绍:我这里使用的是 dhcp+tftp+ftp+kickstat使用的组合工具
yum -y install xinetd dhcpd tftpdtftp-server syslinux system-config-kickstart
# 运行system-config-kickstart命令然后保存ks.cfg文件
vim /etc/dhcp/dhcpd.conf
subnet 192.168.8.0 netmask 255.255.255.0 {
option routers 192.168.8.101;
range 192.168.8.103 192.168.8.200;
option domain-name-servers 192.168.8.101;
filename "pxelinux.0";
next-server 192.168.8.101;
default-lease-time 600;
max-lease-time 7200;
}
# 改完之后重新dhcpd
# 命令详解
# option routers dhcp路由地址
# range dhcp分配地址池
# default-lease-time dhcp默认时长
# filename pxe服务名称
# next-server pxe服务器地址
# allow members pxe最大值
vim /etc/xinetd.d/tftp
disable = no
# 将disable 改为no 改完之后重新瞬间守护进程
service xinetd restart
mount -t iso9660 /dev/sr0 /mnt
# 1. pxelinux.0, vesamenu.c32放到tftp根目录下 这个目录/var/lib/tftpboot/是默认的
cp/usr/share/syslinux/{pxelinux.0,vesamenu.c32} /var/lib/tftpboot/
# 2.创建pxelinux.cfg目录 ，该目录下准备存放default文件
mkdir /var/lib/tftpboot/pxelinux.cfg
# 3.创建要安装系统目录CentOS，拷贝initrd.imgvmlinuz至该目录
mkdir /var/lib/tftpboot/CentOS
cp /mnt/images/pxeboot/{initrd.img,vmlinuz}/var/lib/tftpboot/
cp /mnt/isolinux/isolinux.cfg/var/lib/tftpboot/pxelinux.cfg/default
cp ks.cfg /var/www/html/
vim /var/lib/tftpboot/pxelinux.cfg/default
default vesamenu.c32

#重新启动服务
service xinetd restart
service dhcpd restart
# ftp文件不需要做修改
# 使用命令system-config-kickstart
# 将命令生成的文件ks.cfg 复制到ftp目录下
cp /mnt /var/ftp/cdrom #将光盘整个打包放置ftp目录下
chmod 744 ks.cfg
# ks.cfg 文件如下

错误1： 使用system-config-kickstart命令之后无法选择软件
解决：必须在本地新建一个yum源 我这使用的是cd

baseurl=file:///var/ftp/cdrom
enabled=1
gpgcheck=0
错误2：CentOS时提示an error has occurred. - no valid devices were found
解决：更换光盘
