This method is useful if you are already using RBEnv to manage Ruby, or if you are already a Ruby developer. If neither of these cases are true, just use the system Ruby method as described in the readme.

Follow the instructions to set up RBEnv and Ruby Build on your WebFaction server.

Once you have done so, install Ruby 2.4 . Then set the local Ruby and install the Gem. Finally unset the local Ruby so that you don't run into problems.

$ rbenv install 2.7.0 # Installs Ruby 2.7.0
$ rbenv local 2.7.0 # Sets Ruby 2.7.0 as the default version in the current folder.
$ gem install letsencrypt_webfaction # Installs this utility from RubyGems.
$ rbenv rehash # Makes RBenv aware of the letsencrypt_webfaction utility.
$ rm .ruby-version # Unsets Ruby 2.7.0 as the default version in the current folder.

Instead of the cron command in the readme, when using rbenv it would look like the following:

18 3 * * *     RBENV_ROOT=~/.rbenv RBENV_VERSION=2.7.0 ~/.rbenv/bin/rbenv exec letsencrypt_webfaction --letsencrypt_account_email [[email protected]] --domains [yourdomain.com,www.yourdomain.com] --public ~/webapps/[yourapp/your_public_html]/ --quiet --username [yourusername] --password [yourpassword]

To upgrade the installed version, run:

RBENV_VERSION=2.7.0 gem install letsencrypt_webfaction
