wd mycloud ex4 开启nfs

wd mycloud ex4升级后nfs功能没有了，如何恢复呢？计划重新安装一个，在检查wd时发现在/usr/sbin下有些nfs相关的文件nfs内容如下

其中create_nfs_needed_files ()delete_nfs_needed_files () 分别是建立和删除环境，start_up_nfs ()stop_of_nfs ()启动、停止nfs功能。下边主程序几个入口：start、stop、p2p、restart等，我们只需要start和stop就可以了。
复制一个nfsnew，修改成

改运行权限

nfs的配置文件见下图

最后添加开机启动
忘记怎么加的了，/usr/local/config/config.xml是配置文件，其中有nfs enable 0字样（当时不是用的这个）。
另外改了nfs配置要exportfs -r

————————————————————————————

重启后nfsnew没了，放到public里一份，先把nfsnew文件cp到sbin，然后start
再把exports文件cp到etc，exportfs -arv，OK (｀・ω・´)
