网络系统安装部署

一  安装

 yum -y install dhcp tftp-* vsftpd pykickstart-*

二 配置 dhcpd.conf

  vim /etc/dhcpd.conf

ddns-update-style interim;
ignore client-updates;

subnet 192.168.18.0 netmask 255.255.255.0 {

 

     option routers 192.168.18.1;
     option subnet-mask  255.255.255.0;
     option domain-name-servers 192.168.18.153;

     range dynamic-bootp 192.168.18.100 192.168.18.200;
     default-lease-time 21600;
     max-lease-time 21600;
     filename "pxelinux.0";
     next-server 192.168.18.153;
}

三 启动

  service dhcpd restart

[root@localhost ~]# service dhcpd restart
关闭 dhcpd：                                               [确定]
启动 dhcpd：                                               [确定]

四 配置  tftp
 
   vim /etc/xinetd.d/tftp

# default: off
# description: The tftp server serves files using the trivial file transfer \
#       protocol.  The tftp protocol is often used to boot diskless \
#       workstations, download configuration files to network-aware printers, \
#       and to start the installation process for some operating systems.
service tftp
{
        socket_type             = dgram
        protocol                = udp
        wait                    = yes
        user                    = root
        server                  = /usr/sbin/in.tftpd
        server_args             = -s /tftpboot
        disable                 = no
        per_source              = 11
        cps                     = 100 2
        flags                   = IPv4
}

 [root@localhost ~]# cd pxelinux.cfg/
 [root@localhost ~]# mv isolinux.cfg default
 [root@localhost ~]# cd pxelinux.cfg/
 
配置 
 [root@localhost ~]# vim default

default menu.c32
#prompt 1
