mount沒有權限？

是rw權限。什么情況？

看下權限，755，沒有問題啊

root@pts/4?#?ll

total?16

drwxr-xr-x?4?root?root?4096?Dec??3?11:30?client

drwxr-xr-x?2?root?root?4096?Dec?25?15:17?flash

drwxr-xr-x?6?root?root?4096?Dec??3?16:46?touch

drwxr-xr-x?7?root?root?4096?Dec??3?15:47?web賦值777權限試試？

root@pts/4?#?chmod?-R?777?/tmp/sem/

chmod:?changing?permissions?of?`/tmp/sem/client':?Read-only?file?system

chmod:?changing?permissions?of?`/tmp/sem/flash':?Read-only?file?system

chmod:?changing?permissions?of?`/tmp/sem/web/model2':?Read-only?file?system

服務器的文件系統(tǒng)損壞了？驗證下

root@pts/1?#?mkdir?1

192.168.3.150?[/tmp/sem]?2014-12-26?12:08:18

root@pts/1?#?ls

1??client??flash??touch??web

服務器端沒有問題啊。

難道是nfs問題嗎？

root@pts/1?#?vim?/etc/exports

/tmp/htdocs/sem?*?(rw)

沒有看出來，重啟下nfs試試？

192.168.3.150?[/www/youyuan.com.1/htdocs/sem]?2014-12-26?12:49:59

報配置文件有誤，*和(rw)之間不能有空格。

修正下吧，“*”范圍太大了

root@pts/1?#?vim?/etc/exports

/tmp/htdocs/sem?192.168.0.0/22(rw,sync,no_root_squash)

重啟nfs：

root@pts/1?#?/etc/init.d/nfs?restart

Shutting?down?NFS?mountd:??????????????????????????????????[??OK??]

客戶端在試一下？

root@pts/4?#?touch?1

touch:?cannot?touch?`1':?Permission?denied

這次報訪問拒絕，這個是與權限相關的，再次賦值777試試？

root@pts/4?#?touch?1

192.168.0.193?[/tmp/sem]?2014-12-26?13:01:47

root@pts/4?#?ls

1??client??flash??touch??web

root@pts/4?#?rm?1

可以了，修正權限為755

root@pts/4?#?touch?1

192.168.0.193?[/tmp/sem]?2014-12-26?13:02:14

root@pts/4?#?ls

1??client??flash??touch??web
