Capistrano is an open-source tool used for automating the deployment of web applications to remote servers. In this tutorial, we will go through the steps of installing Capistrano on Ubuntu Server Latest.
Before moving onto the installation process, you first need to have the following:
Capistrano is built on top of Ruby, so it is essential to have Ruby installed on your server. You can install Ruby by running the following command:
sudo apt update
sudo apt install ruby-full
This will install the latest version of Ruby on your server.
Bundler is a popular Ruby gem that is used to manage dependencies for Ruby applications. Capistrano relies on Bundler to manage its dependencies. You can install Bundler by running the following command:
sudo gem install bundler
Once you have installed Ruby and Bundler, you can now proceed to install Capistrano. To install Capistrano, you need to create a new Ruby project and add Capistrano to the Gemfile.
To create a new Ruby project, run the following command:
mkdir myapp
cd myapp
You need to initialize the project using the following command:
bundle init
This will create a Gemfile for your project.
To add Capistrano to your project, you need to add the following line to your Gemfile:
gem 'capistrano', '~> 3.14'
To install Capistrano, run the following command:
bundle install
This will install Capistrano along with its dependencies.
Now that you have installed Capistrano, it's time to configure it for your project. Capistrano uses a set of configuration files to manage the deployment process. The configuration files are stored in a folder called config at the root of your project directory.
To generate the default configuration files, run the following command:
bundle exec cap install
This will create a config/deploy.rb file and a config/deploy/ folder with a set of configuration files for the different environments.
With Capistrano configured, you are now ready to deploy your application. To deploy your application, you need to run the following command:
bundle exec cap <environment> deploy
Replace <environment> with the name of the environment to deploy to, such as staging or production. This will deploy your application to the remote server.
Congratulations! You have successfully installed Capistrano on your Ubuntu Server Latest and deployed your application using it.
If you want to self-host in an easy, hands free way, need an external IP address, or simply want your data in your own hands, give IPv6.rs a try!
Alternatively, for the best virtual desktop, try Shells!
