I googled and found that since the port is over 1024 I needed to add the insecure option to the relevant line in /etc/exports on the server. Once I did that (and ran exportfs -r ), the mount -a on the client wor ked. //如果端口号大于1024,

I googled and found that since the port is over 1024 I needed to add the "insecure" option to the relevant line in /etc/exports on the server. Once I did that (and ran exportfs -r), the mount -a on the client worked.

//如果端口号大于1024,则需要将 insecure 选项加入到配置文件(/etc/exports)相关选项中mount客户端才能正常工作:

查看 exports 手册中关于 secure 选项说明也发现确实如此

[root@lzgonline init.d]# man exports

secure,This option requires that requests originate on an Internet port less than IPPORT_RESERVED (1024). This option is on by default. To turn it off, specify insecure.

//secure 选项要求mount客户端请求源端口小于1024(然而在使用 NAT 网络地址转换时端口一般总是大于1024的),默认情况下是开启这个选项的,如果要禁止这个选项,则使用 insecure 标识

修改配置文件/etc/exports,加入 insecure 选项

/home/lzgonline/rootfs *(insecure,rw,async,no_root_squash)

保存退出

然后重启nfs服务:service nfs restart

然后问题就解决了
