筹备 FTP和HTTP安装
对于FTP和HTTP安装来说,ISO映像文件应该通过回路挂载在公用的目录下,如下面的格式:
对于DVD:
mount -o loop /location/of/disk/space/RHEL5.iso /export/directory/
在这里,/export/directory 将通过FTP或HTTP作为共享目录。
对于CDROM:
mount -o loop /location/of/disk/space/diskX.iso /export/directory/diskX
对于每个CDROM ISO映像文件重复上面的步骤,例如:
mount -o loop /var/isos/disk1.iso /var/www/html/rhel5-install/disk1/之后,确保/export/directory 目录通过FTP或HTTP共享,并且验证客户的访问。你可以检查这个目录是否可以从服务器自身来访问,然后再从你准备安装的同一个子网的其他机器上进行访问。
筹备NFS安装
对于NFS安装来说,没有必要挂载iso映像。使iso映像通过NFS可用就足够了。你可以把iso映像移到NFS的输出目录来使它可用。
对于DVD:
mv /location/of/disk/space/RHEL5.iso /export/directory/
对于CDROM:
mv /location/of/disk/space/disk*.iso /export/directory/
在/etc/exports里进行设置确保 /export/directory通过NFS输出。
要输出到指定的系统:
/export/directory client.ip.address(ro,no_root_squask)
要输出到所有系统里,使用如下的设置:
/export/directory*(ro,no_root_squask)
启动NFS守护进程在红帽企业Linux系统里,使用/sbin/service nfs start命令如果NFS已在运行,重新加载配置文件在红帽企业Linux系统上运行 /sbin/service nfs reload
 

Storage media

For installation media on an http server the address should resemble "http://servername.example.com/pub/dist/rhel5" where the actual source on your local host is /var/www/html/pub/dist/rhel5.
For installation media on an ftp server the address should resemble "ftp://servername.exampe.com/dist/rhel5", where the actual source on your local host is /var/ftp/pub/dist/rhel5.
For installation media on an NFS server the address should resemble "nfs:servername.example.com:/dist/rhel5". The actual location depends on your NFS share. Use the system-config-nfs command to configure NFS to share media.
For more information on configuring these network services read the relevant sections of your Red Hat Enterprise Linux Deployment Guide in the System->Documentation menu.
