/opt/wwwroot 192.168.142.174(rw,sync,no_root_squash)
将文件夹/opt/wwwroot共享给192.168.142.0/24网段，允许读写操作
- 客户机地址可以是主机名、IP地址、网段地址，允许使用*、？通配符
- 权限选项中的含义
- rw表示允许读写（ro为只读）
- sync表示同步写入
- no_root_squash表示当客户机以root身份访问时赋予本地root权限（默认是root_squash，将作为nfsnobody用户降权对待）

调整服务器端的selinux
[root@server ~]# getenforce
Enforcing
[root@server ~]# setenforce 0
客户端再次查看
[root@client ~]# showmount -e 192.168.142.173

关闭服务器端的iptables
[root@server ~]# /etc/init.d/iptables stop

客户端继续测试
[root@client ~]# showmount -e 192.168.142.173
Export list for 192.168.142.173:
/opt/wwwroot 192.168.142.0/24
/var/ftp/pub 192.168.4.110,192.168.4.11
能够查看到服务器端发布的信息，总结
- 服务器端的配置文件写正确，然后重启rpcbind，nfs服务
- 服务器端的iptables需要关闭
手动挂载NFS共享目录到/test下面
[root@client ~]# mkdir /test
[root@client ~]# mount 192.168.142.173:/opt/wwwroot /test
[root@client ~]# tail -1 /etc/mtab
192.168.142.173:/opt/wwwroot /test nfs rw,vers=4,addr=192.168.142.173,clientaddr=192.168.142.174 0 0
[root@client ~]# mount | grep opt

编辑/etc/fstab实现自动挂载

自动挂载成功
客户端写文件测试
[root@client ~]# cd test
bash: cd: test: No such file or directory
[root@client ~]# cd /test
[root@client test]# echo "this is test from client" > fromclient.txt
服务器端查看
[root@server ~]# cd /opt/wwwroot/
[root@server wwwroot]# ls
fromclient.txt
[root@server wwwroot]# cat fromclient.txt
this is test from client
