sudo /etc/init.d/nfs-kernel-server restart

⑤ 检查nfs服务器中挂载的目录。

NFS 的默认传输协议是 UDP,而PC机与嵌入式系统通过UPD交互时就会出现严重的网卡丢包现象.可用的解决方案是:在客户端改用TCP协议,使用下面的命令,

mount -t nfs -o intr,nolock,tcp,rsize=1024,wsize=1024 192.168.100.10:/home/nfs /mnt/nfs

mount -t nfs -o nolock -o tcp 192.168.100.10:/home/nfs /mnt/nfs

https://www.jianshu.com/p/aad01daf1447

修改完成后，保存并退出“ /etc/exports” 文件。然后新建“ /nfsroot”目录，并为该目录
设置最宽松的权限：
vmuser@Linux-host:~$ sudo mkdir /nfsroot
vmuser@Linux-host:~ s u d o c h m o d − R 777 / n f s r o o t v m u s e r @ L i n u x − h o s t sudo chmod -R 777 /nfsroot vmuser@Linux-host ~ sudochmod−R777/nfsrootvmuser@Linux−host sudo chown -R nobody /nfsroot

3、启动 NFS 服务

在虚拟机命令框执行如下命令，可以启动 NFS 服务：
vmuser@Linux-host ~$ sudo /etc/init.d/nfs-kernel-server start
执行如下命令则可以重新启动 NFS 服务：
vmuser@Linux-host ~$ sudo /etc/init.d/nfs-kernel-server restart
执行启动命令后，其操作结果如图所示，表示 NFS 服务已正常启动。

Networking support

–>Networking options
–>TCP/IP networking
–>IP:kernel level autoconfiguration
File systems

–>Network File System
–>NFS client support
–>Root file system on NFS

showmount -e 192.168.161.133 #成功检测到共享
cat /var/log/messages |grep nfs

2)举例说明：

NFS Server IP :192.168.168.0.200

客户端： 192.168.0.201

#snoop 192.168.0.200 192.168.0.201

这行命令表示抓 192.168.0.200和192.168.0.201之间的数据流。抓取的信息如图3所示。

showmount -e 显示某台主机的/etc/exports所共享的目录数据

showmount -a 显示当前主机与客户端NFS联机共享状态

showmount -e

https://www.csdn.net/tags/MtzaAgxsOTk2MjctYmxvZwO0O0OO0O0O.html
在查看对应的挂载信息的时候，也可以使用命令nfsstat，如下所示：

[root@nfsclient~]# nfsstat -m（查看挂载的NFS的信息）

/opt from192.168.1.70:/

解决方案：

将rpcbind服务启动即可。

[root@nfsserver~]# /etc/init.d/rpcbind start（启动rpcbind服务）
