Introduction

This document will give you steps to install LinuxFr.org website on your Debian Stretch development machine.

Note that all commands which require root access are prefixed by sudo.

Install Debian packages

Packages to install from main Stretch source:

~ $ sudo apt install mysql-server mysql-client libmysql++-dev git \
build-essential openssl libreadline-dev curl libcurl4-openssl-dev zlib1g \
zlib1g-dev libssl-dev libxml2-dev libxslt-dev autoconf libgmp-dev libyaml-dev \
ncurses-dev bison automake libtool imagemagick libc6-dev hunspell \
hunspell-fr-comprehensive redis-server ruby ruby-dev ruby-rack

Note:

  • you can use libcurl4-gnutls-dev instead of libcurl4-openssl-dev.
  • the mysql packages will install MariaDB on Debian Stretch

Get LinuxFr.org code and external resources

Use git to get LinuxFr.org sources:

~ $ git clone git://github.com/linuxfrorg/linuxfr.org.git

To be able to reach ruby external resources, you need the bundler packager. The minimal required version is written at the end of the Gemfile.lock file. Actually, Debian has the 1.13.6 version and the lock file requires already the 1.16.4 version.

So we first install the bundler packager directly from rubygems.org:

~ $ gem install --user-install bundler

Don't forget to update your PATH environment according to the warning message shown during installation.

Now, we can reach external Ruby resources:

~ $ cd linuxfr.org
~/linuxfr.org $ bundle config set path 'vendor/bundle'
~/linuxfr.org $ bundle install
~/linuxfr.org $ bundle check

The check command above should say you there's no problem.

Install the LinuxFr.org board

The board-linuxfr gem server is used to allow users chat on the /boards and the collaborative redaction space to work asynchronously.

To install it, the simplest is to run gem install --user-install board-linuxfr

Configure LinuxFr.org

To configure LinuxFr.org, you need to copy both sample configuration files:

~/linuxfr.org $ cp config/database.yml{.sample,}
~/linuxfr.org $ cp config/secrets.yml{.sample,}

For the database, you'll need to configure both development and test section. Set there the MySQL password you will use for connections in clear text and eventually the database names to use (they have to be two different databases). In this document we'll assume you took the default values for database names: linuxfr_rails and linuxfr_test.

Note that, on production, you'll need to customize secrets inside the secrets.yml file.

Configure SQL data base

Prepare time zones information inside the mysql database:

~ $ mysql_tzinfo_to_sql /usr/share/zoneinfo | sudo mysql mysql

Create LinuxFr.org databases and MySQL users:

~/linuxfr.org $ sudo mysql
> CREATE DATABASE linuxfr_rails CHARACTER SET utf8mb4;
> CREATE USER linuxfr_rails IDENTIFIED BY 'linuxfr_rails password';
> GRANT ALL PRIVILEGES ON linuxfr_rails.* TO linuxfr_rails;
>
> CREATE DATABASE linuxfr_test CHARACTER SET utf8mb4;
> CREATE USER linuxfr_test IDENTIFIED BY 'linuxfr_test password';
> GRANT ALL PRIVILEGES ON linuxfr_test.* TO linuxfr_test;
>
> quit

Now every thing is ready and we can ask rails to setup our databases with every structures needed:

~/linuxfr.org $ bin/rails db:setup

Run LinuxFr.org

Now, you can run LinuxFr.org server with:

~/linuxfr.org $ bin/rails server

If everything were good, you can reach the server with a browser inside the virtual machine using the http://localhost:3000 URL.

Additionally, you run the boards within another terminal:

~/linuxfr.org $ board-linuxfr -s -a localhost -p 9000

Configure redirection

This extra step isn't really needed to be able to use LinuxFr.org.

In the config/environments/development.rb file, there are two domains set inside variables MY_DOMAIN and IMG_DOMAIN. By default both domains are dlfp.lo.

You'll find this domain inside some documents like emails to confirm user subscription. To simplify your usage of LinuxFr.org, you should consider install a website locally using this domain name.

Set the domain dlfp.lo to target localhost:

~ $ sudo bash -c 'echo "127.0.0.1 dlfp.lo" >> /etc/hosts'

For Nginx, create a new server configuration with content like:

server {
    server_name dlfp.lo;
    access_log /var/log/nginx/dlfp.access.log;

    listen 0.0.0.0:80;

    location ~ ^/medias/ {
      root /home/linuxfr/linuxfr.org/uploads;
    }

    # Avatars files uploaded on linuxfr server are stored in partitions
    # with folder name containing 3 digits
    location ~ ^/avatars/\d\d\d/ { 
      root /home/linuxfr/linuxfr.org/uploads;
    }

    # Avatars URLs has to be served by the image service
    location ~ ^/avatars/ {
        # To install the LinuxFr img service, see: https://github.com/linuxfrorg/img-LinuxFr.org
        proxy_pass http://localhost:8000;
    }

    location /img/ {
        # To install the LinuxFr img service, see: https://github.com/linuxfrorg/img-LinuxFr.org
        proxy_pass http://localhost:8000;
    }

    # To install the LinuxFr board, see: https://github.com/linuxfrorg/board-sse-linuxfr.org
    location /b/ {
        proxy_buffering off;
        proxy_pass http://localhost:9000;
    }

    location / {
        proxy_set_header X_FORWARDED_PROTO $scheme;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header Host $http_host;
        proxy_redirect off;
        proxy_pass http://localhost:3000;
    }
}

and restart the web server:

~ $ sudo systemctl restart nginx

Now, on the virtual machine, you can access LinuxFr.org with the http://dlfp.lo URL.

Create administrator

To create new users, you can use directly the website.

Although, to set roles on users, you need to manually edit one user directly in the database.

For example, to set as admin the user with login admin_login:

$ sudo mysql linuxfr_rails
> update accounts set role = 'admin' where login = 'admin_login' ;

Then, you can update other users role directly from the URL http://dlfp.lo/admin/comptes.

Finally, you'll certainly need to visit http://dlfp.lo/admin/ to configure sections, forums...

Sections for news

To be able to create your first news, you will need to add sections with link http://dlfp.lo/admin/section.

Be sure to set title LinuxFr.org to one of your sections, otherwise you won't be able to create news in the redaction space.
