请尝试一下:下载 iso 并将其放在 /data/iso 中,例如:
[root@geppetto ~]# ls -al /data/iso
total 708620
drwxr-xr-x. 2 root root 4096 Oct 17 14:40 .
drwxr-xr-x. 3 root root 4096 Oct 17 14:36 ..
-rw-r--r--. 1 root root 725614592 Jul 7 19:26 CentOS-6.3-x86_64-LiveCD.iso
然后挂载
[root@geppetto ~]# mkdir -p /media/centos6.3-64-live
[root@geppetto ~]#
[root@geppetto ~]# mount -t iso9660 /data/iso/CentOS-6.3-x86_64-LiveCD.iso /media/centos6.3-64-live
然后通过 nfs 导出它的父目录,
[root@geppetto ~]# cat /etc/exports
/export/iso cal-26.oma.be(ro)
[root@geppetto ~]#
[root@geppetto ~]# service nfs reload
[root@geppetto ~]# showmount -e
Export list for geppetto.oma.be:
/export/iso cal-26.oma.be
[root@geppetto ~]#
然后将其挂载到客户端
[root@cal-26 ~]# mount -v -t nfs puppet-me.oma.be:/export/iso /geppettoiso
mount.nfs: timeout set for Thu Oct 25 13:39:16 2012
mount.nfs: trying text-based options 'vers=4,addr=192.168.16.49,clientaddr=192.168.15.194'
[root@cal-26 ~]#
在 NFS 服务器上可以浏览:
[root@geppetto media]# ls -al
total 10
drwxr-xr-x. 3 root root 4096 Oct 17 15:23 .
dr-xr-xr-x. 26 root root 4096 Oct 25 11:28 ..
dr-xr-xr-x. 5 root root 2048 Jul 7 19:23 centos6.3-64-live
[root@geppetto media]#
[root@geppetto media]# ls -al /media/centos6.3-64-live/
total 30
dr-xr-xr-x. 5 root root 2048 Jul 7 19:23 .
drwxr-xr-x. 3 root root 4096 Oct 17 15:23 ..
dr-xr-xr-x. 3 root root 2048 Jul 7 19:22 EFI
-r--r--r--. 1 root root 18416 Jul 7 19:23 GPL
dr-xr-xr-x. 2 root root 2048 Jul 7 19:23 isolinux
dr-xr-xr-x. 2 root root 2048 Jul 7 19:24 LiveOS
[root@geppetto media]#
但在 nfs 客户端上,它看起来就像原始 iso 文件:
[root@cal-26 geppettoiso]# ls -al /geppettoiso/CentOS-6.3-x86_64-LiveCD.iso
-rw-r--r--. 1 root root 725614592 Jul 7 19:26 /geppettoiso/CentOS-6.3-x86_64-LiveCD.iso
[root@cal-26 geppettoiso]#
原始文件:
[root@geppetto media]# ls -al /data/iso/CentOS-6.3-x86_64-LiveCD.iso
-rw-r--r--. 1 root root 725614592 Jul 7 19:26 /data/iso/CentOS-6.3-x86_64-LiveCD.iso
[root@geppetto media]#
只是为了完整性:
[root@cal-26 geppettoiso]# mount | grep -i iso
puppet-me.oma.be:/export/iso on /geppettoiso type nfs4 (rw,relatime,vers=4.0,rsize=524288,wsize=524288,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=192.168.15.194,local_lock=none,addr=192.168.16.49)
[root@cal-26 geppettoiso]#
[root@geppetto media]# mount | grep -i iso
/data/iso/CentOS-6.3-x86_64-LiveCD.iso on /media/centos6.3-64-live type iso9660 (ro,loop=/dev/loop0)
/data/iso on /export/iso type none (rw,bind)
[root@geppetto media]#
答案1
据我所知,一旦您的 NFS 共享已安装,只需在客户机器。NFS 共享被视为本地文件系统的一部分。
