/nfs/public 192.168.0.0/255.255.0.0(ro,sync,all_squash)
/nfs/app 192.168.0.0/255.255.0.0(rw,sync,all_squash)

rw:可读写
ro: 只读
no_root_squash：对root用户不压制，如果客户端以root用户写入，在服务端都映射为服务端的root用户
root_squash：默认情况使用的是相反参数root_squash，如果客户端是用户root操作，会被压制成nobody用户
all_squash: 不管客户端的使用nfs的用户是谁，都会压制成nobody用户
insecure: 允许从客户端过来的非授权访问
sync: 数据同步写入到内存和硬盘
async: 数据先写入内存，不直接写入到硬盘
anonuid: 指定uid的值，此uid必须存在于/etc/passwd中
anongid: 指定gid的值
