在AWS EC2上安装Ruby 2.0和Rails 4.0.0beta

Question

Installing Ruby 2.0.0 and Rails 4.0.0beta1 on the default Amazon EC2 Linux install (Amazon Linux AMI 2012.09.1) goes smoothly. But openssl gets in the way (eg http://railsapps.github.com/openssl-certificate-verify-failed.html ) and weird either prevent openssl from getting installed or causing the RubyGem package manager from installing rails.

How can I work around these problems?

Answer 1

Log into your brand new instance:

[19:59:22] paul:~ $ ssh -i ~/.ssh/server.pem ec2-user@your.ip

   __|  __|_  )
   _|  (     /   Amazon Linux AMI
  ___|\___|___|

  https://aws.amazon.com/amazon-linux-ami/2012.09-release-notes/

and impersonate the root:

$ sudo su -

You are logged in as root from here. Apply the server updates:

[root@ip-xx ~]# yum update
...
Complete!
[root@ip-xx ~]# yum groupinstall "Development Tools"
...
Install      72 Package(s)
...
Complete!

Now, this is where it differs from the standard solution. Install RVM but without a distribution of ruby:

[root@ip-xx ~]# \curl -L https://get.rvm.io | bash -s stable

Installing RVM to /usr/local/rvm/
    Creating group 'rvm'

# RVM:  Shell scripts enabling management of multiple ruby environments.
# RTFM: https://rvm.io/
# HELP: http://webchat.freenode.net/?channels=rvm (#rvm on irc.freenode.net)
# Cheatsheet: http://cheat.errtheblog.com/s/rvm/
# Screencast: http://screencasts.org/episodes/how-to-use-rvm

# In case of any issues read output of 'rvm requirements' and/or 'rvm notes'

Installation of RVM in /usr/local/rvm/ is almost complete:

  * First you need to add all users that will be using rvm to 'rvm' group,
    and logout - login again, anyone using rvm will be operating with `umask u=rwx,g=rwx,o=rx`.

  * To start using RVM you need to run `source /etc/profile.d/rvm.sh`
    in all your open shell windows, in rare cases you need to reopen all shell windows.

# root,
#
#   Thank you for using RVM!
#   I sincerely hope that RVM helps to make your life easier and
#   more enjoyable!!!
#
# ~Wayne

Let's check that no ruby version is installed:

[root@ip-xx ~]# rvm list

rvm rubies


# No rvm rubies installed yet. Try 'rvm help install'.

Now, openssl is already installed on the system but is incompatible with setup:

[root@ip-xx ~]# openssl version
OpenSSL 1.0.0k-fips 5 Feb 2013

[root@ip-xx ~]# openssl version -d
OPENSSLDIR: "/etc/pki/tls"

Attempting to install ruby2 with this version will result in the following error:

[root@ip-xx ~]# rvm install 2.0.0 -- --with-openssl-dir=/etc/pki/tls

Although you'll get ruby2, the "Installation of rubygems did not complete successfully" - notice the warning: "Error running 'env GEM_PATH=..."

Instead, we'll get RVM install a copy of openssl for us (see https://rvm.io/packages/openssl/ ). The zlib-devel package is required:

[root@ip-xx ~]# yum install zlib-devel
...

Answer 2

Here is a variant with rbenv.

SSH into your brand new instance:

   __|  __|_  )
   _|  (     /   Amazon Linux AMI
  ___|\___|___|

https://aws.amazon.com/amazon-linux-ami/2012.09-release-notes/
There are 16 security update(s) out of 57 total update(s) available
Run "sudo yum update" to apply all updates.
Amazon Linux version 2013.03 is available.
[jimjh ~]$ ruby --version
ruby 1.9.3p286 (2012-10-12 revision 37165) [x86_64-linux]

Impersonate the root and apply server updates:

$> sudo su -
$> yum update

Install couple of packages:

$> yum install git pcre pcre-devel

Clone rbenv :

$> git clone git://github.com/sstephenson/rbenv.git /usr/local/rbenv

Create the following file:

# /etc/profile.d/rbenv.sh
export RBENV_ROOT=/usr/local/rbenv
export PATH="${RBENV_ROOT}/bin:$PATH"
eval "$(rbenv init -)"

Install ruby-build :

$> . /etc/profile
$> git clone https://github.com/sstephenson/ruby-build.git /usr/local/rbenv/plugins/ruby-build

Install ruby:

$> rbenv install 2.0.0-p195  # wait ...
$> rbenv global 2.0.0-p195
$> rbenv rehash

Update rubygems and install passenger:

$> gem update --system
$> gem install bundler     
$> gem install passenger

Install nginx through passenger:

$> passenger start

At the time of writing, the latest version of passenger is 4.0.0, which works with ruby 2.0.0.

Elastic Beanstalk If you are using Elastic Beanstalk, stop passenger

$> sudo service passenger stop

Initialize rbenv by adding the following to /opt/elasticbeanstalk/support/envvars.d/appenv

. /etc/profile.d/rbenv.sh

Start passenger

$> sudo service passenger start
