Windows folder sharing, firewall turned off. The linux network mount folder is mounted locally.

mount -t cifs -o username=Administrator,password="123456",
rw,dir_mode=0777,file_mode=0777 //192.168.1.26/test /var/www/test/

上面命令是一行，中间没换行。
大概意思是
先把windows里面的test文件夹设置共享，防火墙关掉。
然后在linux上mount过来， 加 rw,dir_mode=0777,file_mode=0777 保证一挂载过来的文件夹可读可写。。 
192.168.1.26 是windows的ip
username=Administrator,password="123456"是我windows的账号密码
最后挂载到了 /var/www/test/ 下。进去就能看到了。

Virtual Windows Mount VirtualBox shared folder:

First, turn on the virtual machine shared folder option, and then press the 1st floor operation.

After installing the enhanced function, restart Windows and mount it directly. There is an extra I drive ~~
