VMware中CentOS 7设置文件夹共享

通过VMware Tools实现物理机与虚拟机之间的文件共享。然而CentOS 7在安装（或更新）VMware Tools可能会遇到一些问题，需要手动修改源文件并打包，重新安装。

1. 环境说明

环境	版本
物理机	Windows 10
VMware	VMware Workstation 12 Pro, 版本是 12.5.2 build-4638234
CentOS 7	kernel-3.10.0-514.21.1.el7.x86_64

2. 检查VMware Tools
   检查是否已经安装了VMware Tools, 如果已经安装好，可以跳到步骤4，配置共享文件夹。
   单击菜单 虚拟机

• 如果下拉列表中出现了如下图所示的 更新 VMware Tools ，则说明已经安装好了（但这并不意味着能成功配置共享文件夹，如果此时VMware默认的共享目录/mnt/hgfs/不存在，那基本意味着需要重新安装了），可以暂时跳过安装步骤。
  
  

  检查是否已经安装了VMware Tools
• 如果出现 安装 VMware Tools ，则直接点击安装

3. 安装 VMware Tools

• 点击安装VMware Tools或更新VMware Tools后， CentOS会自动挂载VMware Tools， 双击打开，将里面的VMwareTools-X.tar.gz复制到桌面上
  
  

  拷贝安装文件到桌面
• 在桌面打开终端，解压tar.gz包

 [hadoop@centos7-2 Desktop]$ tar -xzvf VMwareTools-10.0.10-4301679.tar.gz 

• 进入解压得到的vmware-tools-distrib目录，开始安装(需要已root身份进行)，过程中遇到需要输入信息的，一路回车下去，采用默认设置即可

[hadoop@centos7-2 vmware-tools-distrib]$ sudo ./vmware-install.pl  

安装过程可能不会一路顺利，比如会遇到以下错误

上网查了下，此时需要修改vmware-tools-distrib/lib/modules/source/vmhgfs-only/page.c

[hadoop@centos7-2 vmware-tools-distrib]$ cd lib/modules/source/
[hadoop@centos7-2 source]$ tar -xvf vmhgfs.tar 
[hadoop@centos7-2 source]$ cd vmhgfs-only/
[hadoop@centos7-2 vmhgfs-only]$ chmod 777 page.c #该文件是只读的，这里随便更改了下权限，只要让它可写就行
[hadoop@centos7-2 vmhgfs-only]$ vi page.c 
# 进入文件编辑模式
:set number # 显示行号
:1639 # 跳到第1639行，需要对该行进行修改

把第1639行的：
if LINUX_VERSION_CODE >= KERNEL_VERSION(3, 19, 0)
改成
if LINUX_VERSION_CODE >= KERNEL_VERSION(3, 10, 0)
说明：因为 CentOS 7 的内核版本是 3.10.0
修改保存后，重新归档

[hadoop@centos7-2 source]$ mv vmhgfs.tar vmhgfs.tar.bak
[hadoop@centos7-2 source]$ tar -cvf vmhgfs.tar vmhgfs-only
[hadoop@centos7-2 source]$ cd ../../..
[hadoop@centos7-2 vmware-tools-distrib]$ sudo ./vmware-install.pl   

此后一路回车下去，最终看到如下信息，表示安装成功

Creating a new initrd boot image for the kernel.
   Starting Virtual Printing daemon:                                   done
Starting vmware-tools (via systemctl):  [  OK  ]
The configuration of VMware Tools 10.0.10 build-4301679 for Linux for this running kernel completed successfully.

Enjoy,

重新启动CentOS

4. 配置共享文件夹

打开虚拟机设置

进入虚拟机设置

启用共享文件夹，添加物理机上需要共享的目录

启用共享文件夹，添加物理机上需要共享的目录

VMware默认的共享路径是在/mnt/hgfs，这是写死在VMware Tools的脚本里的，我们可以从/etc/init.d/vmware-tools查到：

vmhgfs_mnt="/mnt/hgfs"
#Mount all hgfs filesystems" 
vmware_mount_vmhgfs() {
   if [ "`is_vmhgfs_mounted`" = "no" ]; then
    if [ "`vmware_vmhgfs_use_fuse`" = "yes" ]; then
       mkdir -p $vmhgfs_mnt
       vmware_exec_selinux "$vmdb_answer_BINDIR/vmhgfs-fuse \
        -o subtype=vmhgfs-fuse,allow_other $vmhgfs_mnt"
     else
        vmware_exec_selinux "mount -t vmhgfs .host:/ $vmhgfs_mnt"
     fi
 fi
}

此时在CentOS 7中就能看到物理机上面共享的文件夹了：

[hadoop@centos7-2 ~]$ ll /mnt/hgfs/
dr-xr-xr-x. 1 root root 0 Jun 15 00:17 pc-share

至此物理机与虚拟机CentOS 7之间的文件夹共享设置就成功了。
