在Linux VPS上实现挂载Google Drive只映射不同步

本教程将帮你实现在Linux VPS上挂载Google Drive只映射不同步。这样不会占用本地磁盘，也可以高效的利用远程Google Drive。实现效果如下图。

首先我们需要一个KVM的VPS。OpenVZ虚拟化的VPS是肯定不行的。这里推荐用DigitalOcean。

系统用Debian 7 64 bit

apt-get update
apt-get dist-upgrade

更新系统至最新

root@GoogleDrive:~# uname -a
Linux GoogleDrive 3.2.0-4-amd64 #1 SMP Debian 3.2.54-2 x86_64 GNU/Linux
root@GoogleDrive:~# cat /etc/issue
Debian GNU/Linux 7 \n \l
root@GoogleDrive:~#

安装如下packages

apt-get install ocamapt-get install ocaml
apt-get install ocaml-findlib
apt-get install sqlite3
apt-get install camlidl
apt-get install m4 libcurl4-gnutls-dev libfuse-dev libsqlite3-dev
apt-get install camlp4-extra
apt-get install fuse
apt-get install build-essential sudo ssh make gitl

安装opam

git clone https://github.com/OCamlPro/opam
cd opam
./configure && make && make install

Build Successful in 76.86s. 840 jobs (parallelism 1.8x), 1124 files generated.

mkdir -p /usr/local/share/man/man1 && cp doc/man/* /usr/local/share/man/man1

root@GoogleDrive:~/opam# opam init

Do you want OPAM to modify ~/.bashrc and ~/.ocamlinit?
(default is 'no', use 'f' to name a file other than ~/.bashrc)
    [N/y/f] {type enter}
...

1. To configure OPAM in the current shell session, you need to run:

      eval `opam config env`

2. To correctly configure OPAM for subsequent use, add the following
line to your profile file (for instance ~/.bashrc):

      . /root/.opam/opam-init/init.sh > /dev/null 2> /dev/null || true

3. To avoid issues related to non-system installations of `ocamlfind`
  add the following lines to ~/.ocamlinit (create it if necessary):

      let () =
        try Topdirs.dir_directory (Sys.getenv "OCAML_TOPLEVEL_PATH")
        with Not_found -> ()
      ;;

1.trouble shooting:

=-=-= Synchronizing package archives =-=-=
[ERROR] Actions cancelled because of # opam-version    1.1.1 (71b2a01ee571507c1819fbd282b0500d628f92d3)

You need to add some swap to be able to run this installation.

当你看到如下的时候就说明已经开始下载编译和安装了

这里会卡一段时间，正常的

=-=-= Installing ocamlnet.3.7.3 =-=-=

进入Google Project建立一个Project

https://console.developers.google.com/project

进入项目的API设置开启Drive API

 

建立一个OAuth验证ID

建立项目的Client ID

 

记录下这两个生成的参数做稍后使用

进入/root/.opam/system/bin/目录绑定项目

cd /root/.opam/system/bin/
./google-drive-ocamlfuse -headless -label googledrive -id ##Client ID##.apps.googleusercontent.com -secret ##secret key##

执行完上述指令会返回一个https的网址在浏览器粘贴到浏览器后会进入google页面询问是否允许访问该项目，选accept然后记录下浏览器页面返回的密码

例如：

root@GoogleDrive:~/.opam/system/bin# ./google-drive-ocamlfuse -headless -label googledrive -id 123123231.apps.googleusercontent.com -secret ASDASDASDASQWE!@#
Please, open the following URL in a web browser: https://accounts.google.com/o/oauth2/auth?client_id=123123231.apps.googleusercontent.com&redirect_uri=urn%3Aietf%3Awg%3Aoauth%3A2.0%3Aoob&scope=https%3A%2F%2Fwww.googleapis.com%2Fauth%2Fdrive&response_type=code&access_type=offline&approval_prompt=force
Please enter the verification code:[input here]
Access token retrieved correctly.
root@GoogleDrive:~/.opam/system/bin#

进入~/.gdfuse/googledrive

cd ~/.gdfuse/googledrive
nano config

编辑config修改内容例如

verification_code= [key returned from browser]

client_id= [eg. 123123231.apps.googleusercontent.com]

client_secret= [eg. ASDQWEWGSD!$@#@#ASD]

完成配置加载Google Drive远端存储到本地/googledrive

mkdir /googledrive
cd ~/.opam/system/bin
./google-drive-ocamlfuse -label googledrive /googledrive
