a trouble of nfs service
1、This is the nfs service's configure file
[root@localhost public]# vi /etc/exports /home/public 60.191.63.*(rw,root_squash) 2、The nfs service directory is /home/public,it like this: [root@localhost public]# pwd /home/public [root@localhost public]# ls -l total 0 -rw-r--r-- 1 nfsnobody nfsnobody 0 04-29 03:00 han -rw-r--r-- 1 nfsnobody nfsnobody 0 04-29 03:12 yz [root@localhost public]# touch zy [root@localhost public]# ls -l total 0 -rw-r--r-- 1 nfsnobody nfsnobody 0 04-29 03:00 han -rw-r--r-- 1 nfsnobody nfsnobody 0 04-29 03:12 yz -rw-r--r-- 1 root root 0 04-29 06:42 zy 3、the client pc's ip address is 60.191.63.9,login as root,according above /etc/exports configure the directory of /home/public as root_squash,as this,root is squashed the user of nfsnobody,while i mount the nfs file,i shouldn't delete zy file,but to my surprise i delete it. [root@localhost public]# ls -l 总计 0 -rw-r--r-- 1 nfsnobody nfsnobody 0 04-29 03:00 han -rw-r--r-- 1 nfsnobody nfsnobody 0 04-29 03:12 yz -rw-r--r-- 1 root root 0 2009-04-29 zy [root@localhost public]# rm -f zy [root@localhost public]# ls -l 总计 0 -rw-r--r-- 1 nfsnobody nfsnobody 0 04-29 03:00 han -rw-r--r-- 1 nfsnobody nfsnobody 0 04-29 03:12 yz 4、what's the reason? |
Did you restart the nfs server after changing the /etc/exports file?
After restart try mount -o remount /home/public |
