Ruby 1.9.2

Question

Wondering if there is an update on when a Ruby update is expected at WebFaction. I am developing a couple of sites using 1.9.2 at my office, and constantly have syntax errors going backwards to 1.8.7 at WebFaction.

So, any time estimates, or is there a recommended way of using rvm etc. to update our own apps?

thanks,

Peter

Okay, this should do it:

# first, install a rails app from the control panel.
# Use the "Rails 3.1.0 (nginx 1.0.6/Passenger 3.0.9/Ruby Enterprise Edition 1.8.7)" version.

APP_NAME='rails'           # replace with your rails application name (i.e: ~/webapps/$APP_NAME)
PROJ_NAME='hello_world'    # replace with your rails project name     (i.e: ~/webapps/$APP_NAME/$PROJ_NAME)

#### stop the app ###
$HOME/webapps/$APP_NAME/bin/stop    # Also disable the associated cronjob via `crontab -e`

#### install ruby 1.9.2 ####

# do the install:
cd $HOME
bash -s stable < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer )
echo "[[ -s \"$HOME/.rvm/scripts/rvm\" ]] && source \"$HOME/.rvm/scripts/rvm\"  # This loads RVM into a shell session." >> $HOME/.bash_profile

# Now log out and back in  # don't forget this step :)

# re-set your environment variables:
APP_NAME='rails'           # replace with your rails application name
PROJ_NAME='hello_world'    # replace with your rails project name

# check it to make sure it's working:
type rvm | head -n 1       # you should see "rvm is a function"

#### install ruby 1.9.2 ####

rvm install 1.9.2    # take a 5-minute break

# set it as your default and current ruby:
rvm --default use 1.9.2
rvm use 1.9.2

# and ensure that it's right:
ruby --version    # should show ruby 1.9.2 (currently at patch level "p290" as of this writing)

# note, you can switch between ruby versions using:
# rvm use system   # use system ruby (1.8.7)
# rvm use 1.9.2    # use local ruby (1.9.2)
#
# You can also reset everything with:
# rvm reset

#### Installing rvm into passenger ####

# get the ruby version.
RUBY_VERSION=$(echo $(basename $GEM_HOME) | cut -d'-' -f2,3)    # gives something like "1.9.2-p290"

rvm --create use "${RUBY_VERSION}@${APP_NAME}"

# note: in the future, you need to set APP_NAME and PROJ_NAME, then use:
# rvm use "${RUBY_VERSION}@${APP_NAME}"
# in order to "switch" to this ruby app

cd $HOME/webapps/$APP_NAME/$PROJ_NAME/config

# create setup_load_paths.rb . This file generally shouldn't exist already in a new project.
if [[ -f setup_load_paths.rb ]]; then
echo " ---------------------------------------------------------- "
echo "     setup_load_paths.rb already exists. Edit manually.     "
echo " ---------------------------------------------------------- "
else
cat << EOF > setup_load_paths.rb
if ENV['MY_RUBY_HOME'] && ENV['MY_RUBY_HOME'].include?('rvm')
  begin
    rvm_path     = File.dirname(File.dirname(ENV['MY_RUBY_HOME']))
    rvm_lib_path = File.join(rvm_path, 'lib')
    $LOAD_PATH.unshift rvm_lib_path
    require 'rvm'
    RVM.use_from_path! File.dirname(File.dirname(__FILE__))
  rescue LoadError
    # RVM is unavailable at this point.
    raise "RVM ruby lib is currently unavailable."
  end
end
EOF
fi

Helpful webfaction engineers - rvm get head worked correctly.

That let me finish going thru the above script line by line, and I got to the end without error.

However, I think I configured something incorrectly - when I run bin/restart I get an error on my port saying the address is already in use e.g. nginx: [emerg] bind()

Looked in the nginx conf file - it had the wrong root (was pointing to old $PROJ_NAME in new $APP_NAME). e.g. should be:

.../webapps/paper_caddy/paper-caddy/public.

I modified this file and tried to restart again - same problem.

Could you take a look please...

You can search for and manually kill old PIDs by the open port number. Replace the 12345 at the end with your app's port number,

[you@webx]$ netstat -antuwp | egrep "(^[^t])|(^tcp.*LISTEN)" | grep 12345
tcp        0      0 0.0.0.0:12345              0.0.0.0:*                   LISTEN      8070/httpd.worker

In this case the PID is 8070, you would kill the pid like this,

kill -9 8070

This should force the application on that port to close and the new app to restart without a problem.

Running rvm install 1.9.2 makes prompt for root password: password required for 'rhn-channel -l':

How to avoid it?
