阿正老師教你免費玩Amazon EC2雲端主機(下篇)：主機實戰篇

• Amazon 雲端服務(一) - Amazon 的 AWS 以及 EC2 申請
• Amazon 雲端服務(二) - 透過 EC2 來產生 Instance

UNPROTECTED PRIVATE KEY FILE!  
permissions 0644 for 'xxxxx.pem' are too open.
It is recommended that your private key files are NOT accessible by others.
This private key will be ignored.
bad permissions: ignore key: xxxxx.pem
Permission denied (publickey).

chmod 400 xxxxx.pem

#ssh -i xxxx.pem ec2-user@ec2-50-19-62-58.compute-1.amazonaws.com

• Ruby 
• RubyGems 
• Rails 
• Apache + Passenger（註：Passenger為一Apache_mod，可將Apache與RoR做結合）

更新 yum

$sudo -s //root
$yum update 

將ec2-user加入rvm群組

$ groupadd rvm
$ gpasswd -a ec2-user rvm

安裝預先需求套件

$ yum install -y gcc-c++ patch readline readline-devel zlib zlib-devel libyaml-devel libffi-devel openssl-devel make bzip2 autoconf automake libtool bisonniconv-devel git sqlite-devel libcurl-devel 

install RVM

$ curl -L get.rvm.io | bash -s stable 

ec2-user登出再重新登入 (否則會回rvm命令找不到) $ rvm -v

install Ruby      this may take time...

$ rvm install 1.9.3
$ ruby -v //確認安裝

install Rails    this may take time...

$ gem update
$ gem install rails
$ rails -v 

install Apache     

$ yum install httpd -y
$ yum install httpd-devel -y

install Passenger     

$ gem install passenger

install Passenger on Apache    

$ passenger-install-apache2-module 

install sqlite3 and mysql   

$ yum install mysql mysql-devel

vim httpd.conf   

修改新增Apache客製設定檔 e.g. custom.conf

[root@domU-12-31-39-09-C0-EF conf.d]# ruby -v
ruby 1.9.3p362 (2012-12-25 revision 38607) [x86_64-linux]
[root@domU-12-31-39-09-C0-EF conf.d]# passenger -v
Phusion Passenger version 3.0.19

$ cd /etc/httpd/conf.d
$ vi custom.conf

[root@domU-12-31-39-09-C0-EF conf.d]# vi custom.conf
                                                                                   

LoadModule passenger_module /usr/local/rvm/gems/ruby-1.9.3-p362/gems/passenger-3.0.19/ext/apache2/mod_passenger.so
