VMware中CentOS 7設定資料夾共享

通過VMware Tools實現物理機與虛擬機器之間的檔案共享。然而CentOS 7在安裝（或更新）VMware Tools可能會遇到一些問題，需要手動修改原始檔並打包，重新安裝。

1. 環境說明

環境	版本
物理機	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. 檢查VMware Tools
   檢查是否已經安裝了VMware Tools, 如果已經安裝好，可以跳到步驟4，配置共享資料夾。
   單擊選單 虛擬機器

• 如果下拉選單中出現瞭如下圖所示的 更新 VMware Tools ，則說明已經安裝好了（但這並不意味著能成功配置共享資料夾，如果此時VMware預設的共享目錄/mnt/hgfs/不存在，那基本意味著需要重新安裝了），可以暫時跳過安裝步驟。
  
  

  檢查是否已經安裝了VMware Tools
• 如果出現 安裝 VMware Tools ，則直接點選安裝

3. 安裝 VMware Tools

• 點選安裝VMware Tools或更新VMware Tools後， CentOS會自動掛載VMware Tools， 雙擊開啟，將裡面的VMwareTools-X.tar.gz複製到桌面上
  
  

  拷貝安裝檔案到桌面
• 在桌面開啟終端，解壓tar.gz包

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

• 進入解壓得到的vmware-tools-distrib目錄，開始安裝(需要已root身份進行)，過程中遇到需要輸入資訊的，一路回車下去，採用預設設定即可

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

安裝過程可能不會一路順利，比如會遇到以下錯誤

上網查了下，此時需要修改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 #該檔案是隻讀的，這裡隨便更改了下許可權，只要讓它可寫就行
[hadoop@centos7-2 vmhgfs-only]$ vi page.c 
# 進入檔案編輯模式
:set number # 顯示行號
:1639 # 跳到第1639行，需要對該行進行修改

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)
說明：因為 CentOS 7 的核心版本是 3.10.0
修改儲存後，重新歸檔

[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   

此後一路回車下去，最終看到如下資訊，表示安裝成功

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,

重新啟動CentOS

4. 配置共享資料夾

開啟虛擬機器設定

啟用共享資料夾，新增物理機上需要共享的目錄

VMware預設的共享路徑是在/mnt/hgfs，這是寫死在VMware Tools的指令碼里的，我們可以從/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
}

此時在CentOS 7中就能看到物理機上面共享的資料夾了：

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

至此物理機與虛擬機器CentOS 7之間的資料夾共享設定就成功了。
