virtualbox - 设置共享文件夹

 

正常操作：

1 添加共享文件夹

设置-》共享文件夹-》添加共享路径。

 

2 linux 内部挂载共享目录

mount -t vboxsf 共享文件名称 /mnt/文件夹名称
mount -v vboxsf software /mnt/hsoft

 

 

3 设置开机启动

添加执行权限： chmod +X etc/rc.d/rc.local  x是大写

编辑： vi /etc/rc.local 或者 vi /etc/rc.d/rc.local  

mount -t vboxsf software /mnt/hsoft

指定挂载目录的用户组：
如果挂载时候需要指定目录权限，先获取用户组ID
如www -》 id www
uid=1000(www) gid=1000(www) groups=1000(www)

挂载目录是www用户组
mount -t vboxsf -o uid=1000,gid=1000,umask=022 software /mnt/hsoft

 

 df -h 查看磁盘情况，验证磁盘是否加入成功，目录共享成功

常见问题：

1 挂载失败 -unknown filesystem type vboxsf

mount -t vboxsf software /mnt/hsoft

提示：-unknown filesystem type vboxsf

 
解决：安装虚拟增强。设备-》安装增强功能。

 

 或者设置存储，设置光盘选择VBoxGuestAdditions.ios（在安装目录）。没有可以去官网下载

 

 

安装成功以后一般在 /media/GuestAdditionsISO 有VBoxLinuxAdditions.run文件。

 

 执行：

./VBoxLinuxAdditions.run

然后挂载

mount -t vboxsf software /mnt/hsoft

2 增强时候报错

./VBoxLinuxAdditions.run

解决：

yum -y install build-essential gcc make perl 

3 增强以后 /media/目录下无 /GuestAdditionsISO/VBoxLinuxAdditions.run
find / -name VBoxLinuxAdditions.run 不存在文件

第一种方式：

存储 添加光驱  VBoxGuestAdditions.iso，centos 挂载。

yum update kernel -y
yum install kernel-devel kernel-headers -y
yum install the gcc make perl -y

uname -r
reboot
uname -r

iso文件挂载到自己的系统中,lsblk 查看下设备号.
lsblk

mkdir /mnt/cdrom
mount /dev/sr0  /mnt/cdrom

cd /mnt/cdrom
./VBoxLinuxAdditions.run

vi /etc/rc.d/rc.local
mount /dev/sr0  /mnt/cdrom

查看挂载
df -h

 

 

第二种方式：下载导入VBoxGuestAdditions.iso文件。根据virtualbox版本下载。比如我的virtualbox是5.2.16
下载目录：http://download.virtualbox.org/virtualbox/5.2.16/

http://download.virtualbox.org/virtualbox/5.2.16/VBoxGuestAdditions_5.2.16.iso

 

wget 下载
wget http://download.virtualbox.org/virtualbox/5.2.16/VBoxGuestAdditions_5.2.16.iso

[root@localhost home]# ls
ftpuser  VBoxGuestAdditions_5.2.16.iso

mount -o loop /home/VBoxGuestAdditions_5.2.16.iso /media/GuestAdditionsISO

cd /media/GuestAdditionsISO

ls -l

./VBoxLinuxAdditions.run
