I'm writing a webhook to automatically publish a site when I push to GitHub. Part of the process requires that I build the site with
bundle exec middleman build --clean
I was able to figure this out. First, I installed rvm as a multi-user installation to ensure the
www-data account can access it.
$ curl -sSL https://get.rvm.io | sudo bash -s stable
Install the desired ruby version, in my case 2.3.1, then set rvm to use it:
$ rvm install 2.3.1 $ rvm use 2.3.1
gem to install any gems that are needed. Because rvm is a multi-user installation, these gems are stored to the system and not your specific user.
$ gem install packagename
I don't know if this is necessary, but I would close the SSH session and reopen it. rvm messes with environment variables, so better safe than sorry.
env to print all environment variables.
printenv also works if
env doesn't for some reason. You'll get a big list of everything set, you only need the ruby-related ones. Do not copy/paste these values, they are examples I pulled from my system. Yours will be different!
PATH=/usr/local/rvm/gems/ruby-2.3.1/bin:/usr/local/rvm/gems/ruby-2.3.1@global/bin:/usr/local/rvm/rubies/ruby-2.3.1/bin:/usr/local/rvm/bin:/home/steven/bin:/home/steven/.local/bin:/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin:/usr/games:/usr/local/games:/snap/bin rvm_bin_path=/usr/local/rvm/bin GEM_HOME=/usr/local/rvm/gems/ruby-2.3.1 IRBRC=/usr/local/rvm/rubies/ruby-2.3.1/.irbrc MY_RUBY_HOME=/usr/local/rvm/rubies/ruby-2.3.1 rvm_path=/usr/local/rvm rvm_prefix=/usr/local rvm_ruby_string=ruby-2.3.1 GEM_PATH=/usr/local/rvm/gems/ruby-2.3.1:/usr/local/rvm/gems/ruby-2.3.1@global RUBY_VERSION=ruby-2.3.1
Now we need PHP to recognize these variables. You'll need to find the right file on your system, which can be tricky. I don't have a way of knowing which one is correct, I used trial and error.
The file on my system is
/etc/php/5.6/fpm/pool.d/www.conf. Add all of the environment variables you previously grabbed into this file with the below format. Note that you DO need
PATH in here as well!
env[rvm_path] = /usr/local/rvm env[rvm_prefix] = /usr/local
php-fpm. Your service name may be different from mine; I'm using the 5.6 build from ondrej/php.
Ubuntu 15.04 and newer (systemd):
$ sudo systemctl restart php5.6-fpm
Ubuntu 14.10 and newer:
$ sudo service php5.6-fpm restart
Finally, in the script itself you'll need to
cd to the directory you're running the
bundle command from. My short script is this:
cd /opt/slate /usr/bin/git reset --hard /usr/bin/git pull bundle exec middleman build --clean cp -R /opt/slate/build/* /var/www/docs
Works for me!
