pxe 远程安装linux

[root@slave1 ~]# mount -t iso9660 -o loop CentOS-6.3-x86_64-bin-DVD1.iso /linshi/

[root@slave1 ~]# cp -r /linshi/* /Centos/

[root@slave1 ~]# yum install -y dhcp*

[root@slave1 ~]# yum install -y tftp*

[root@slave1 ~]# yum install -y rpcbind

[root@slave1 ~]# yum install -y nfs-utils-*

配置tftp
注意：关闭selinux
[root@slave1 ~]# vi /etc/selinux/config
SELINUX=disabled

[root@slave1 ~]# vi /etc/xinetd.d/tftp
service tftp
{
socket_type = dgram
protocol = udp
wait = yes
user = root
server = /usr/sbin/in.tftpd
server_args = -u nobody -s /tftpboot //-s 表示用/tftpboot作为tftp目录的根目录
disable = no //修改成no
per_source = 11
cps = 100 2
flags = IPv4
}

[root@slave1 ~]# service xinetd restart

配置：dhcp

[root@slave1 tftpboot]# vi /etc/dhcp/dhcpd.conf
