在AWS EC2上安裝Ruby 2.0和Rails 4.0.0beta

Question

在默認Amazon EC2 Linux安裝（Amazon Linux AMI 2012.09.1）上安裝Ruby 2.0.0和Rails 4.0.0beta1可以順利進行。 但openssl阻礙（例如http://railsapps.github.com/openssl-certificate-verify-failed.html）和怪異阻止openssl安裝或導致RubyGem包管理器安裝rails。

我該如何解決這些問題？

登錄到你的品牌新的實例：

[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/ 

和冒充根：

$ sudo su - 

你從這裏以root身份登錄。應用服務器更新：

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

現在，這是它與標準解決方案不同的地方。安裝RVM但沒有紅寶石的分佈：

[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 

讓我們來看看，沒有紅寶石版本安裝：

[root@ip-xx ~]# rvm list 

rvm rubies 


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

現在，OpenSSL是已經安裝在系統上，但不符合設置：

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

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

嘗試安裝此版本的ruby2將導致以下錯誤：

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

雖然你會得到ruby2，在「RubyGems的安裝沒有成功完成」 - 請注意警告：「錯誤運行「ENV GEM_PATH = ...」

相反，我們會得到RVM安裝openssl的副本給我們（見https://rvm.io/packages/openssl/）。 zlib的-devel軟件包要求：

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

Please note that it's required to reinstall all rubies:

Answer 2

這是一個rbenv的變種。

SSH到你的品牌新的實例：

__| __|_ ) 
    _| ( / 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] 

冒充根和應用服務器更新：

$> sudo su - 
$> yum update 

包夫婦安裝：

$> yum install git pcre pcre-devel 

克隆rbenv：

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

創建以下文件：

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

安裝ruby-build：

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

安裝Ruby：

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

更新RubyGems的安裝乘客：

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

直通客車安裝nginx的：

$> passenger start 

在寫作的時候，乘客的最新版本是4.0.0，它與紅寶石2.0.0工作。

彈性魔豆 如果使用的是彈性魔豆，加制止乘客

$> sudo service passenger stop 

初始化rbenv以下到/opt/elasticbeanstalk/support/envvars.d/appenv

. /etc/profile.d/rbenv.sh 

開始乘客

$> sudo service passenger start
