NFS：安裝時服務器拒絕訪問。客戶端是一個LXC proxmox（！）

Question

抱歉，但我開始相同的話題，因爲它https://stackoverflow.com/questions/22246477/mounting-nfs-results-in-access-denied-by-server

我做的解決方案的所有步驟，但它沒有任何意義我。仍然不起作用。

我有什麼：

服務器爲U buntu 14.04.5 LTS

客戶端的Ubuntu 14.04.2 LTS - 這是proxmox LXC

#cat /etc/exports 

/nfs  192.168.88.0/24(ro,fsid=0,insecure,no_root_squash,no_subtree_check,sync) 
/nfs/keycdn 192.168.88.0/24(rw,nohide,insecure,no_root_squash,no_subtree_check,sync) 

如果我從服務器運行此命令：

mount 192.168.88.185:/nfs/keycdn /mnt 

它的安裝和工作 - 我可以創建一個文件

如果我在客戶端上運行，我得到一個錯誤：

root@kafka-02:/# mount 192.168.88.185:/nfs/keycdn /mnt 
mount.nfs: access denied by server while mounting 192.168.88.185:/nfs/keycdn 

我有一個文件夾上這樣的權利： 服務器

#ll /nfs/ 
drwxrwxrwx 3 nobody nogroup 4096 Mar 27 13:49 ./ 
drwxr-xr-x 24 root root 4096 Mar 27 12:41 ../ 
drwxrwxrwx 2 nobody nogroup 4096 Mar 27 15:17 keycdn/ 

要修改/ etc/exports中我跑exportfs -rav和服務NFS的內核服務器重新啓動後生效

我試圖定義的NF VERS s在客戶端的/ etc/fstab中。但沒有效果

有上運行冗長mount命令在服務器和客戶端：

服務器

Answer 1

只有當您使用LXC proxmox時，此答案纔有幫助，但我認爲您應該在其他情況下嘗試使用他。

問題出在proxmox方面。 Proxmox已經知道了，那東西阻止了一切。

要停止AppArmor的，讓他無法正常工作，做這個步驟

# /etc/init.d/apparmor stop 
# /etc/init.d/apparmor teardown 
# update-rc.d apparmor disable 

在此之後

步驟都開始工作就像一個魅力
