1、在客户端挂载NFS文件系统出现如下错误：
pi@raspberrypi:/mnt $ sudo mount -t nfs -o nolock,rw,async,wsize=32768,rsize=327 68 192.168.2.35:/share /mnt/share mount.nfs: access denied by server while mounting 192.168.2.35:/share pi@raspberrypi:/mnt $ sudo mount -t nfs -o nolock,rw,async,wsize=32768,rsize=32768 192.168.2.35:/share /mnt/share mount.nfs: access denied by server while mounting 192.168.2.35:/share pi@raspberrypi:/mnt $
2、查看NFS文件系统配置文件访问限制在192.168.1.0网段
root@ubuntu-mate:~# nano /etc/exports GNU nano 2.2.6 File: /etc/exports # /etc/exports: the access control list for filesystems which may be exported # to NFS clients. See exports(5). # # Example for NFSv2 and NFSv3: # /srv/homes hostname1(rw,sync,no_subtree_check) hostname2(ro,sync,no_sub$ # # Example for NFSv4: # /srv/nfs4 gss/krb5i(rw,sync,fsid=0,crossmnt,no_subtree_check) # /srv/nfs4/homes gss/krb5i(rw,sync,no_subtree_check) # /share 192.168.1.*(rw,sync,no_root_squash,no_subtree_check)
3、原来服务器IP为1段，后来改为了2段，所以把192.168.1.*替换为192.168.2.*，重新启动NFS服务即可。
root@ubuntu-mate:~# /etc/init.d/nfs-kernel-server restart [ ok ] Restarting nfs-kernel-server (via systemctl): nfs-kernel-server.service. root@ubuntu-mate:~#
