--第一步，修改配置文件
[root@serv01 share]# vim /etc/exports
[root@serv01 share]# cat /etc/exports
/share 192.168.1.0/255.255.255.0(rw,all_squash,anonuid=501,anongid=501)172.16.1.0/255.255.255.0(rw)
#/share192.168.1.0/24(rw,all_squash,anonuid=501,anongid=501)
--第二步，重启服务
[root@serv01 share]# /etc/init.d/nfs restart

--第三步，测试
