How to Install AlchemyCMS Rails Framework on Ubuntu Linux

AlchemyCMS is an open-source, headless content management system (CMS) based on Rails that adapts to your needs. It makes it super easy to develop and design static websites and is one of the leading open-source CMS frameworks based on Rails.

You can use AlchemyCMS to create your personal or business websites in minutes by creating markup pages and content. It splits pages into logical parts like headlines, paragraphs, images, etc.

The only thing it stores in the database is text, ids of images, and rich text content. Nothing else.

For more about AlchemyCMS, check its homepage.

These are the packages we’re going to set up.

  • Ruby version 2.5.3
  • Rails version 5.2.1
  • MySQL Server

Install Ruby

You’ll need to install some dependencies to install Ruby and Rails on Ubuntu. To make that happen, install Node.js and Yarn repositories. This will make installing the dependencies easier.

First, install these curl and git packages.

sudo apt update
sudo apt install curl git

Then run the commands below to add Node.js and Yarn repositories and keys to your system. Then install some core packages to get your environment going.

curl -sL | sudo -E bash -
curl -sS | sudo apt-key add -
echo "deb stable main" | sudo tee /etc/apt/sources.list.d/yarn.list

sudo apt-get update
sudo apt-get install nodejs yarn zlib1g-dev build-essential libpq-dev libssl-dev libreadline-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt1-dev libcurl4-openssl-dev libffi-dev

When you’re done, Continue below:

After adding the repositories and installing the necessary packages above, install Ruby with your local profile settings using rbenv. You’ll then use rbenv to install ruby-build.

cd ~/
git clone ~/.rbenv
echo 'export PATH="$HOME/.rbenv/bin:$PATH"' >> ~/.bashrc
echo 'eval "$(rbenv init -)"' >> ~/.bashrc
exec $SHELL

git clone ~/.rbenv/plugins/ruby-build
echo 'export PATH="$HOME/.rbenv/plugins/ruby-build/bin:$PATH"' >> ~/.bashrc
exec $SHELL

After setting up your local profile, run the commands below to install Ruby version 2.5.3. If a newer version is available, replace the version number with that. Then, visit this site to find out about Ruby’s latest versions.

rbenv install 2.5.3
rbenv global 2.5.3

To verify that Ruby is installed, run the commands below:

ruby -v

You should see similar lines below:

ruby 2.5.3p105 (2018-10-18 revision 65156) [x86_64-linux]

Another package management you’ll want to install is bundler. to do that, run the commands below

gem install bundler

Now run the command below after installing the bundler.

rbenv rehash

Install MySQL Server

MySQL server can be installed on Ubuntu by running the commands below:

sudo apt-get install mysql-client mysql-server libmysqlclient-dev

Install Rails

Now that the Ruby environment is set up run the commands below to install Rails. Rails can be installed from Node.Js. First, run the commands below to install the Node.js repository, then install the Node.js package.

curl -sL | sudo -E bash -
sudo apt-get install -y nodejs

Now that Node.js is installed run the commands below to install Rails.

gem install rails -v 5.2.1

Don’t forget to rehash your rbenv environment installing install new packages.

rbenv rehash

To verify if Rails is installed, run the commands below.

rails -v

You should see something similar to the lines below:

Rails 5.2.1

The installation of AlchemyCMS is very easy. First, you need to run Ruby’s gem command. To do that, run the commands below.

gem install alchemy_cms
npm install gm

Configure AlchemyCMS

Now that your environment is ready run the commands below to install Alchemy CMS and build your first site. Alchemy is a Rails 4 engine, so you can generate a fresh Rails 4 application by running this command.

rails new alchemycms

Next, change it into the Alchemy CMS folder and install it there.

cd ~/alchemycms

Then run the commands to open the Gemfile there.

nano Gemfile

When it opens, copy and paste the lines below into the file and save.

gem 'alchemy_cms'
gem 'alchemy-devise'

Then the file should look like this:

ruby '2.5.3'
gem 'alchemy_cms'
gem 'alchemy-devise'
# Bundle edge Rails instead: gem 'rails', github: 'rails/rails'
gem 'rails', '~> 5.2.1'
# Use sqlite3 as the database for Active Record
gem 'sqlite3'

Save and exit.

After that, run the commands below:

bundle install

After that, you should see the message below:

Using web-console 3.7.0
Bundle complete! 19 Gemfile dependencies, 103 gems now installed.
Use `bundle info [gemname]` to see where a bundled gem is installed.
Post-install message from alchemy_cms:
