WebFaction Forum / How to install gems for your Rails application.

IAIHMB · 2007-11-22 22:16:49

If you're a WebFaction customer the best way to install gems for your Rails application is to install Ruby and RubyGems in your home directory and update your application of type Rails' autostart.cgi to use your local installation of Ruby. The procedure looks something like this:

Code:

# Install Ruby
cd
mkdir ruby1.8/ ruby1.8/src/
cd ruby1.8/src/
wget ftp://ftp.ruby-lang.org/pub/ruby/1.8/ruby-1.8.6-p110.tar.gz
tar fxz ruby-1.8.6-p110.tar.gz
cd ruby-1.8.6-p110/
./configure --prefix=$HOME/ruby1.8/
make
make install
cd ../../
rm -fr src/

# Add ~/ruby1.8/bin/ and ~/ruby1.8/lib/ruby/gems/1.8/bin/ to your PATH.
cd
echo "export PATH=$HOME/ruby1.8/bin/:$HOME/ruby1.8/lib/ruby/gems/1.8/bin/:\$PATH" >> .bash_profile
source .bash_profile

# Install RubyGems
cd
mkdir temp/
cd temp/
wget http://rubyforge.org/frs/download.php/20989/rubygems-0.9.4.tgz
tar fxz rubygems-0.9.4.tgz
cd rubygems-0.9.4/
ruby setup.rb config
ruby setup.rb install
cd
rm -fr temp/

# Update RubyGems
gem update --system

# Install the Mongrel, MySQL, and PostgreSQL gems.
export POSTGRES_INCLUDE=/usr/local/pgsql/include/
export POSTGRES_LIB=/usr/local/pgsql/lib/
gem install --platform=ruby mongrel mysql postgres

At this point you should install every gem that your Rails application needs.

Code:

# Replace XXX with the name of your application of type Rails in the following command.
cd ~/webapps/XXX/

# Update autostart.cgi to use your installation of Mongrel.
sed -i "s|/usr/local/bin/mongrel_rails|$HOME/ruby1.8/lib/ruby/gems/1.8/bin/mongrel_rails|" autostart.cgi

# Restart Mongrel
kill `cat log/mongrel.pid`
./autostart.cgi

That's it, now you can install gems using "gem install (Gem Name)".

Hope it helps.

Hi - I got a little bit stuck following these instructions:

I got ruby installed, I added the paths, I downloaded Gems, and now Gems is stuck.

[seanharper@web1 rubygems-1.1.0]$ pwd
/home2/seanharper/tmp/rubygems-1.1.0
[seanharper@web1 rubygems-1.1.0]$ ~/ruby1.8/bin/ruby setup.rb
./lib/rubygems.rb:10:in `require': no such file to load -- thread (LoadError)
from ./lib/rubygems.rb:10
from setup.rb:19:in `require'
from setup.rb:19
[seanharper@web1 rubygems-1.1.0]$

Any ideas?

[seanharper@web1 rubygems-1.1.0]$ $PATH
-bash: /home2/josh/git_app/bin:/home2/seanharper/ruby1.8/bin/:/home2/seanharper/ruby1.8/lib/ruby/gems/1.8/bin/:/usr/kerberos/bin:/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin:/home2/seanharper/bin:

Sean,

I su'd into your account and ran Step 1 of the procedure here:
https://help.webfaction.com/index.php?_ … p;nav=0,21

No errors, so I think you're good to go.. just pick up at Step 2

Regards,

@IAIHMB

Im trying to set up Ozark (http://github.com/brennandunn/ozark/tree/master). Have successfully installed Ruby, all the required gems and mongrel but when I try to restart mongrel:

[vomitols@web22 ozark]$ kill `cat log/mongrel.pid`
cat: log/mongrel.pid: No such file or directory
kill: usage: kill [-s sigspec | -n signum | -sigspec] pid | jobspec ... or kill -l [sigspec]

Could you please take a look?

Didn't migrate the db yet. Waiting for this step.
All the best,
Bernardo.

seanf · 2008-07-08 21:13:53

I'm looking in your 'ozark' directory now, and I see no "log" subdirectory.

You can get your PID from:

ps -u vomitols -o pid,command

The PID will be the first column.

@seanf

thank you!

@seanf

Now the site is restarting over and over again.

I went with 1.8.6 (patch level 110) of ruby since that appears to be what webfaction is already using (patch level 0), didn't want to shake the boat too much, not convinced it matters, but anyway,

I'm getting stuck hereabouts:

Code:

[conner@web41 ~]$ gem update --system
Updating RubyGems

Updating rubygems-update

[conner@web41 ~]$ gem -v

[conner@web41 ~]$ which gem
~/ruby1.8/bin/gem

Is there some environment variable i should be setting to keep it inside my space?

conner · 2009-05-07 16:05:43

Code:

[conner@web41 ~]$ gem env

a lot of that looks wrong... i'll keep plugging away at it

apparantly running 'source .bash_profile' wasn't enough, a logout/login seemed to make everything happy.

'which gem' gave me my install of gem, but when interacting with it any other way i got the usr/local install

That's strange... first time I've heard of 'source .bash_profile' not working. But, glad you were able to sort it out

I first got an error for mongrel and mysql, fastthread needs 1.1.2 or higher of rubygem. Couldn't seem to upgrade it using the traditional means, so I used the update rubygem plugin to bring me up, which left me here.

seanf · 2009-05-07 16:29:08

Try the following for the MySQL gem:

Code:

gem install --platform=ruby mysql -- --with-mysql-config=/usr/bin/mysql_config

Hope that helps!
