First, install any missing (also for font) related dependencies:

sudo apt-get update;
sudo apt-get install git unzip build-essential chrpath libssl-dev libxft-dev libfreetype6 libfreetype6-dev libfontconfig1 libfontconfig1-dev fontconfig fontconfig-config fonts-dejavu-core fonts-droid fonts-freefont-ttf fonts-kacst fonts-kacst-one fonts-khmeros-core fonts-lao fonts-liberation fonts-lklug-sinhala fonts-nanum fonts-opensymbol fonts-sil-abyssinica fonts-sil-padauk fonts-takao-pgothic fonts-thai-tlwg fonts-tibetan-machine fonts-tlwg-garuda fonts-tlwg-kinnari fonts-tlwg-loma fonts-tlwg-mono fonts-tlwg-norasi fonts-tlwg-purisa fonts-tlwg-sawasdee fonts-tlwg-typewriter fonts-tlwg-typist fonts-tlwg-typo fonts-tlwg-umpush fonts-tlwg-waree -y;

Then, get a copy of the repository:

git clone https://github.com/ioi/translation.git

Switch to the newly created directory:

cd translation/

And, add the gpg keys needed to make the setup.
The gpg command in the setup will contact a public key server (hkp://keys.gnupg.net) and request the key associated with the RVM project key which is used to sign each RVM release. To get the key, we need to provide the ID that is related to the key, in this case the ID is 409B6B1796C275462A1703113804BB82D39DC0E3. Having the RVM project’s public key allows us to verify the legitimacy of the RVM release we will be downloading, which is signed with the matching private key.

gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3

If the above command fails with the following error

$ gpg --keyserver hkp://keys.gnupg.net --recv-keys 409B6B1796C275462A1703113804BB82D39DC0E3
gpg: requesting key D39DC0E3 from hkp server keys.gnupg.net
?: [fd 4]: read error: Connection reset by peer
gpgkeys: HTTP fetch error 7: couldn't connect: eof
gpg: no valid OpenPGP data found.
gpg: Total number processed: 0

Try using the following alternative:

command curl -sSL https://rvm.io/mpapis.asc | gpg --import -

Afterwards, perform the installation (this might take some time, depending on your connection to the server where it will download the necessary packages and your CPU performance as it will perform some compilation locally):

./deploy.sh

While installing codemirror we got the following prompt:

replace public/codemirror-3.22/doc/upgrade_v3.html? [y]es, [n]o, [A]ll, [N]one, [r]ename:

We typed A and pressed Enter. We are not sure if this is what we are supposed to do but it worked later on properly.

Edit the ./config.yml file and set new values for the api_token and cookie_secret.

api_token: "4c0a6fe55f3d4aa9c5dbb9a59db7b20e"
cookie_secret: "SDfadadsf90u84oh23jnrwf"

You can generate random passwords from here http://bytefreaks.net/random-password-generator

Then start the redis service using the following:

redis-server

 

In an new terminal, go to DbInit folder:

cd translation/DbInit/

and update the files users.json and tasks.json to prepare the initial data to be imported in redis:

The original content of tasks.json is:

[
    { "id": "1",    "title": "notice",     "filename": "notice.md" },
    { "id": "2",    "title": "gondola",    "filename": "gondola.md" },
    { "id": "3",    "title": "friends",    "filename": "friends.md" },
    { "id": "4",    "title": "holiday",    "filename": "holiday.md" }
]

Place the original .md files in this folder. And then initialize redis using the following command:

ruby dbinit.rb

Finally, go to the previous folder and start the translation system:

cd ..;
shotgun -o 0.0.0.0 -p 8080;

Visit http://SERVER_NAME_OR_IP:8080 to view the translation system.

You can use the admin account to make changes to users, to send notifications (if you omit the to field, then the notification will be send to all users) and to check out all task with their translations.

Staff accounts allow you to check out all task with their translations.

Note on the architecture

The deploy.sh script assumes your architecture and OS is 64bit. To find what type of architecture you are using execute uname -i. If the result is not x86_64, then phantomjs will not work for you and you will not be able to generate the PDFs. To fix this issue you need to download the correct version from https://bitbucket.org/ariya/phantomjs/downloads. At the time this tutorial was written deploy.sh was installing version https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-1.9.7-linux-x86_64.tar.bz2, so we installed https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-1.9.7-linux-i686.tar.bz2 using the following commands:

wget https://bitbucket.org/ariya/phantomjs/downloads/phantomjs-1.9.7-linux-i686.tar.bz2;
tar xf phantomjs-1.9.7-linux-i686.tar.bz2;
sudo cp phantomjs-1.9.7-linux-i686/bin/phantomjs /usr/local/bin;
rm -rf phantomjs-1.9.7-linux-i686*;

The above commands follow the example in deploy.sh.

Updating logos and website look

To update the views of the website you can do the by editing the .erb files that are in the translation/views folder.
