1.安裝opam
因為是透過opam來安裝google-drive-ocamlfuse套件，所以要先把opam裝起來。opam有推出CentOS系列的版本，所以只要下載套件庫，就可以透過yum進行安裝。下面針對不同的發行版進行解說。
# yum install sqlite-devel fuse fuse-devel libcurl-devel zlib-devel m4
# yum install ocaml ocamldoc ocaml-camlp4-devel
# wget https://raw.github.com/ocaml/opam/master/shell/opam_installer.sh -O - | sh -s /usr/local/bin/
2.安裝google-drive-ocamlfuse
# opam init
# opam install google-drive-ocamlfuse
# opam list
# google-drive-ocamlfuse --help
3.存取 Google Drive API
Next, we’re going to enable API access to Google Drive and create a set of credentials. These steps require a web browser on your local computer, and access to the Google account with which your Drive is associated.
(a) Visit the Google API developer’s console on your desktop at
https://console.developers.google.com/project
(b) Create a project. Click Create Project, then give the project a name and click Create again:
Google will take a moment to create the project, and when it’s complete you’ll arrive at the dashboard:
(c) Enable the Google Drive API. Click APIs & auth, then APIs when the menu expands. You’ll see a list like the one below. Click on Drive API:
If you don’t see the Drive API on the list as pictured, you may need to search for it. After you’ve selected it, click the blue Enable button at the top of the page.
(d) Click Credentials in the menu on the left side of the page. Then click Add New Credential.
Click Configure consent screen. Google assumes you are writing a piece of software so it wants some information about it.
The product name field is required, but you can leave everything else blank. Then click Save at the bottom of the page.
Now click Other for the application type. Google will ask for a name again - you may use the default or choose a name you’ll easily associate with this project. Then click Create.
Click Credentials on the menu on the left side of the screen, and select your project from the list. You will now be able to view your Client ID and Client secret strings:
4. 授權 OCamlfuse 存取
Next, we’ll provide the credentials for your Drive API to OCamlfuse in your Linode, authorizing it to access your Google Drive.
(a) Authorize your Google Drive link, replacing client-ID and client-secret with those you received from the Google API Manager in the steps above:
QUOTE:
# google-drive-ocamlfuse -headless -label backup -id client-ID -secret client-secret
The output from this command will give you a long URL. Copy it and paste it for use in step 2:
QUOTE:
Please, open the following URL in a web browser: https://accounts.google.com/o/oauth2/auth?client_id=URL_SNIPPED
Please enter the verification code:
(b) Google will ask for permission to allow this new application (OCamlfuse) to access your Google Drive. Click Accept to receive the verification code:
(c) Copy/paste the verification code back to OCamlfuse in your VPS.
5.設定掛載點
QUOTE:
# mkdir -p /Data
# google-drive-ocamlfuse -label backup /Data
用以下指令即可卸載：
# fusermount -u /Data
6.設定開機自動掛載 google driver
首先在根目錄新增一個檔叫 gdfuse
QUOTE:
#!/bin/bash
su root -l -c "google-drive-ocamlfuse -label backup /Data”
exit 0
然後變更權限
# chmod 700 /gdfuse
再加進去 rc.local
# vi /etc/rc.local
再最後面加上
QUOTE:
# Auto Mount Google Driver
/gdfuse
這樣就可以囉～
