在默认的 Amazon EC2 Linux 安装 (Amazon Linux AMI 2012.09.1) 上安装 Ruby 2.0.0 和 Rails 4.0.0beta1 非常顺利。但是 openssl 阻碍了（例如http://railsapps.github.com/openssl-certificate-verify-failed.html）并且奇怪的是阻止 openssl 安装或导致 RubyGem 包管理器安装 rails。
我该如何解决这些问题？

登录到您的全新实例：
[19:59:22] paul:~ $ ssh -i ~/.ssh/server.pem ec2-user@your.ip
__| __|_ )

https://aws.amazon.com/amazon-linux-ami/2012.09-release-notes/
并模拟根：
$ sudo su -
您从这里以 root 身份登录。应用服务器更新：
[root@ip-xx ~]# yum update
...
Complete!
[root@ip-xx ~]# yum groupinstall "Development Tools"
...
Install 72 Package(s)
...
Complete!
现在，这就是它与标准解决方案不同的地方。安装 RVM 但没有 ruby 的分发：
[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
让我们检查一下没有安装 ruby 版本：
[root@ip-xx ~]# rvm list
rvm rubies
# No rvm rubies installed yet. Try 'rvm help install'.
现在，openssl 已经安装在系统上，但与 setup 不兼容：
[root@ip-xx ~]# openssl version
OpenSSL 1.0.0k-fips 5 Feb 2013
[root@ip-xx ~]# openssl version -d
OPENSSLDIR: "/etc/pki/tls"
尝试使用此版本安装 ruby2 将导致以下错误：
[root@ip-xx ~]# rvm install 2.0.0 -- --with-openssl-dir=/etc/pki/tls

相反，我们将让 RVM 为我们安装一个 openssl 副本（请参阅https://rvm.io/packages/openssl/）。zlib-devel 包是必需的：
[root@ip-xx ~]# yum install zlib-devel
...

zlib-devel.x86_64 0:1.2.5-7.11.amzn1

这是 rbenv 的变体。
SSH 进入您的全新实例：
__| __|_ )

模拟根并应用服务器更新：
$> sudo su -
$> yum update
安装几个包：
$> yum install git pcre pcre-devel
克隆rbenv：
$> git clone git://github.com/sstephenson/rbenv.git /usr/local/rbenv
创建以下文件：
# /etc/profile.d/rbenv.sh
export RBENV_ROOT=/usr/local/rbenv
export PATH="${RBENV_ROOT}/bin:$PATH"
eval "$(rbenv init -)"
安装ruby-build：
$> . /etc/profile
$> git clone https://github.com/sstephenson/ruby-build.git /usr/local/rbenv/plugins/ruby-build
安装红宝石：
$> rbenv install 2.0.0-p195 # wait ...
$> rbenv global 2.0.0-p195
$> rbenv rehash
更新 rubygems 并安装乘客：
$> gem update --system
$> gem install bundler
$> gem install passenger
通过passenger安装nginx：
$> passenger start
在撰写本文时，乘客的最新版本是 4.0.0，它适用于 ruby 2.0.0。
Elastic Beanstalk 如果您使用的是 Elastic Beanstalk，请停止乘客
$> sudo service passenger stop
通过添加以下内容来初始化 rbenv/opt/elasticbeanstalk/support/envvars.d/appenv
. /etc/profile.d/rbenv.sh
启动乘客
$> sudo service passenger start
