概述本文以Redhat6.5为基础，通过配置网络安装服务器，实现Redhat Linux的网络安装。主要用到的软件（服务）有DHCP,TFTP,NFS,Kickstart等。本文只列出具体步骤，不含原理说明。1. 基础配置1.1 更改IP地址rootlocalhost # vi /etc/sysconfig/network-scripts/ifcfg-eth0rootlocalhost # cat /etc/sysconfig/network-scripts/ifcfg-eth0 DEVICE=eth0HWADDR=08:00:27:53:44:fbTYPE=EthernetUUID=82affeef-922e-40b2-b89f-a5df8e9fa236ONBOOT=yesNM_CONTROLLED=yesBOOTPROTO=noneIPADDR=192.168.7.30NETMASK=255.255.255.0GATEWAY=192.168.7.1IPV6INIT=noUSERCTL=norootlocalhost # ifup eth0Active connection state: activatedActive connection path: /org/freedesktop/NetworkManager/ActiveConnection/11.2 更改hostnmerootlocalhost # vi /etc/sysconfig/networkrootredhatnis # cat /etc/sysconfig/networkNETWORKING=yesHOSTNAME=redhatnisrootlocalhost # vi /etc/hostsrootlocalhost # cat /etc/hosts127.0.0.1 localhost localhost.localdomain localhost4 localhost4.localdomain4:1 localhost localhost.localdomain localhost6 localhost6.localdomain6192.168.7.30 redhatnis1.3 关闭SELINUX及防火墙（iptables）rootlocalhost # vi /etc/selinux/configrootredhatnis # cat /etc/selinux/config |grep disa#disabled - SELinux is fully disabled.SELINUX=disabledrootlocalhost # chkconfig |grep iptaiptables 0:off1:off2:on3:on4:on5:on6:offrootlocalhost # chkconfig -level 2345 iptables offrootlocalhost # shutdown -ry 02. 软件安装122.1 挂载安装光盘rootredhatnis # mount /dev/sr0 /mntmount: block device /dev/sr0 is write-protected, mounting read-onlyrootredhatnis # df -hFilesystem Size Used Avail Use% Mounted on/dev/mapper/vg_root-lv_root 20G 6.2G 12G 35% /tmpfs 940M 72K 940M 1% /dev/shm/dev/sda1 485M 39M 421M 9% /boot/dev/sr0 3.6G 3.6G 0 100% /mnt2.2 配置YUM源rootredhatnis # cd /etc/yum.repos.drootredhatnis yum.repos.d# vi installmedia.reporootredhatnis yum.repos.d# cat installmedia.repo InstallMedianame=Red Hat Enterprise Linux 6.5baseurl=file:/mnt/Serverenabled=1gpgcheck=0rootredhatnis yum.repos.d# yum listLoaded plugins: product-id, refresh-packagekit, security, subscription-managerThis system is not registered to Red Hat Subscription Management.
