[基础]RHEL6下LINUX服务器批量部署

包准备：xinetd，tftp-server，dhcp，httpd，system-config-kickstart，syslinux，nfs

试验环境：

本机地址：192.168.46.98

本地网关：192.168.46.254

配置DHCP服务器：

Sample:

---

  subnet 192.168.46.0 netmask 255.255.255.0 {

  range 192.168.46.100 192.168.46.105;

  option routers 192.168.46.254;

  default-lease-time 600;

  max-lease-time 7200;

  next-server 192.168.46.98;    /*指向tftp服务器*/

  filename="pxelinux.0"; ｝        /*ftp根目录的相对路径*/

---

参考文件：

ddns-update-style interim; /*dhcp支持的dns动态更新方式*/

ignore client-updates; /*忽略客户端DNS动态更新*/

authoritative; /*授权*/

allow booting; /*支持PXE启动*/

allow bootp; /*支持boottp*/

subnet 192.168.129.0 netmask 255.255.255.0 { /*作用域*/

range 192.168.129.30 192.168.129.78; /*ip地址段范围*/

option routers 192.168.129.1; /*网关*/

option subnet-mask 255.255.255.0; /*子网掩码*/

option domain-name-servers 203.103.24.68; /*DNS服务器的地址*/

default-lease-time 21600; /*租期，秒数*/

max-lease-time 43200; /*最大租期，秒数*/

next-server 192.168.129.22; /*TFTPServer的IP*/

filename "/pxelinux.0"; /*Bootstrap文件*/

挂载系统光盘到 /mnt

配置TFTP根目录（tftpboot）

# cp /mnt/images/pxeboot/vmlinuz  /mnt/images/pxeboot/initrd.img  /var/lib/tftpboot

# cp /mnt/isolinux/boot.msg /mnt/isolinux/splash.jpg  /var/lib/tftpboot

# cp /usr/share/syslinux/pxelinux.0 /var/lib/tftpboot/

# mkdir /var/lib/tftpboot/pxelinux.cfg

# cp -p /media/cdrom/isolinux/isolinux.cfg /var/lib/tftpboot/pxelinux.cfg/default

TFTP下default配置

# vi /var/lib/tftpboot/pxelinux.cfg/default

开启服务

tftp包含于xinetd中，所以要进入配置文件中开启

# vi /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

        per_source              = 11

        cps                     = 100 2

        flags                   = IPv4

}

---

开启

# service dhcpd start

# service xinetd start

# service httpd start

# service nfs start
