由于測(cè)試的東西內(nèi)核版本不一樣，所以新裝了版本的，但是發(fā)現(xiàn)文件共享有問(wèn)題，我另一個(gè)虛擬機(jī)是OK的，早就忘了以前是怎么弄的了，人不能在同一個(gè)坑栽多次不是么？好記性不如爛筆頭，所以特此記錄解決過(guò)程：

1、正常配置文件共享，如下圖：

但是啟動(dòng)linux 客戶機(jī)，執(zhí)行sudo mount 發(fā)現(xiàn)并沒(méi)有生效，/mnt/mac_share下面并沒(méi)有任何東西

安裝客戶端增強(qiáng)工具，報(bào)錯(cuò)：

手動(dòng)mount工具：

jin@k53:~$ sudo mount  /dev/cdrom  /media/cdrom
[sudo] password for jin: 
mount: unknown filesystem type 'iso9660'

2、解決問(wèn)題：
2.1 未知的文件類型iso9660

jin@k53:~$ sudo apt-get install --reinstall linux-image-$(uname -r)

安裝好以后，重新mount

jin@k53:~$ sudo mount  /dev/cdrom  /media/cdrom
mount: block device /dev/sr0 is write-protected, mounting read-only
jin@k53:~$ cd /media/cdrom/
jin@k53:/media/cdrom$ ls
AUTORUN.INF  OS2        VBoxDarwinAdditions.pkg            VBoxLinuxAdditions.run    VBoxWindowsAdditions-amd64.exe  VBoxWindowsAdditions.exe  cert
NT3x         TRANS.TBL  VBoxDarwinAdditionsUninstall.tool  VBoxSolarisAdditions.pkg  VBoxWindowsAdditions-x86.exe    autorun.sh                runasroot.sh
jin@k53:/media/cdrom$ sudo ./VBoxLinuxAdditions.run 
......

vboxadd-service.sh: Starting VirtualBox Guest Addition service.
jin@k53:/media/cdrom$ sudo apt install gcc make perl

2.2 報(bào)錯(cuò)了，發(fā)現(xiàn)有依賴沒(méi)有安裝，那就安裝依賴：

This system is currently not set up to build kernel modules.
Please install the gcc make perl packages from your distribution.

vboxadd-service.sh: Starting VirtualBox Guest Addition service.
jin@k53:/media/cdrom$ sudo apt install gcc make perl

jin@k53:/media/cdrom$ sudo ./VBoxLinuxAdditions.run 
.....
Building the VirtualBox Guest Additions kernel modules.  This may take a while.

  /sbin/rcvboxadd quicksetup <version>
or
  /sbin/rcvboxadd quicksetup all

3、安裝好以后，重新啟動(dòng)

這樣，mac和虛擬機(jī)之間的文件共享就OK了
