NFS配置随手记录

apt-get install nfs-kernel-server
在/etc/exports中加入
/usr/nfsshare *(rw,sync,fsid=0,no_root_squash)
wp@MySQL:~$ sudo /etc/init.d/nfs-kernel-server restart
 * Stopping NFS kernel daemon
   ...done.
 * Unexporting directories for NFS kernel daemon...
   ...done.
 * Exporting directories for NFS kernel daemon...
exportfs: /etc/exports [1]: Neither 'subtree_check' or 'no_subtree_check' specified for export "*:/usr/nfsshare".
  Assuming default behaviour ('no_subtree_check').
  NOTE: this default has changed since nfs-utils version 1.0.x

   ...done.
 * Starting NFS kernel daemon
   ...done.
wp@MySQL:~$ sudo /etc/init.d/idmapd restart
Rather than invoking init scripts through /etc/init.d, use the service(8)
utility, e.g. service idmapd restart

Since the script you are attempting to invoke has been converted to an
Upstart job, you may also use the stop(8) and then start(8) utilities,
e.g. stop idmapd ; start idmapd. The restart(8) utility is also available.
idmapd stop/waiting
idmapd start/running, process 2020

wp@MySQL:~$ sudo exportfs -ra

nfs版本更新后参数不同
客户端的/etc/fstab <nfs-hostname>:共享目录地址 nfs4 defaults 0 0
nfs服务器的修改/etc/exports 内容如下：共享目录地址 *(rw,sync,no_root_squash,no_subtree_check,fsid=0)
更改后不报错
 

 

wp@web:~$ sudo apt-get install rpcbind nfs-common

wp@web:~$ sudo mount 192.168.1.203:/usr/nfsshare /usr/nfsshare
mount.nfs: rpc.statd is not running but is required for remote locking.
mount.nfs: Either use '-o nolock' to keep locks local, or start statd.
mount.nfs: an incorrect mount option was specified

问题锁定，portmap防火墙受阻
测试要求 按照ubuntu server最佳解决方案部署
在服务器端
/etc/hosts.allow中加入portmap mountd nfsd statd lockd rquotad : 192.168.1.201 192.168.1.203
/etc/hosts.deny加入   portmap mountd nfsd statd lockd rquotad : ALL
sudo /etc/init.d/portmap restart
在客户端
/etc/hosts.deny加入   portmap : ALL
/etc/hosts.allow加入  portmap : 192.168.1.203
sudo /etc/init.d/portmap restart
