Install and configure the rails3 + nginx runtime environment on an Amazon EC2 instance

Environment: Ubuntu lts 12.04 (free usage tier)

0. preparation:

0.1. Update the system
$ Sudo apt-Get update
$ Sudo apt-Get upgrade
0.2 install the compiling environment
$ Sudo apt-Get install build-essential Git-core
$ Sudo apt-Get install curl
1. Install rvm and ruby1.9.3
1.1 install rvm
Run the following command:
$ Bash-s stable <(curl-s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)
Modify the. bashrc file. Note that Ubuntu in/home/Ubuntu is the user name and must be replaced with your own.
$ Echo '[[-s "/home/Ubuntu /. rvm/scripts/rvm "] & source"/home/Ubuntu /. rvm/scripts/rvm "'> ~ /. Bashrc
(Or echo "Source \ $ home/. rvm/scripts/rvm" >> ~ /. Bashrc)
Make the modification take effect immediately. Execute:
$ Source. bashrc

1.2 install ruby1.9.3
Install zlib1g
$ Sudo apt-Get install zlib1g zlib1g-dev
Install OpenSSL
$ Rvm PKG install OpenSSL

Installation: (this step is time-consuming and may take 10 minutes)
$ Rvm install 1.9.3 -- With-OpenSSL-Dir = $ home/. rvm/usr
Set the default value:
$ Rvm use -- default 1.9.3
$ Rvm gemset use global
$ Gem list

$ Rvm ruby-1.9.3-p194 @ rails326 -- create -- default
$ Rvm gemset list

1.3 install rails3
$ Gem install rails

Install SQLite
$ Sudo apt-Get install sqlite3 libsqlite3-dev

2. Test the rails Environment
2.1 create a test application: firstapp, path :~ /Webapps/firstapp (~ Point to the root directory of the current user, the same below)
$ Cd
$ Mkdir webapps
$ CD webapps
$ Rails new firstapp
$ CD firstapp
2.2 edit gemfile
$ Nano gemfile
Use nano to edit gemfile and add downstream information to gemfile,
Gem 'therubyracer'
Save and exit. Run
$ Bundle install
2.3 run the rails Service
$ Rails s
2.4 open a browser: (port 3000 must be added to the security policy of the EC2 instance)

Http://ec2-x-x-x-x.ap-southeast-1.compute.amazonaws.com: 3000

If it is enabled successfully, rails installation is complete. (X-X is the IP address of your EC2 instance)

3. Install nginx + passenger
3.1 install passenger
$ Gem install passenger
3.2 install ngigx
Install the dependency package first:
$ Sudo apt-Get install libcurl4-openssl-dev
Run the following command to install nginx. Two options are displayed: select 1 to install nginx1.2.1.
$ Rvmsudo passenger-install-nginx-Module
The default installation path is/opt/nginx.

3.3 download nginx Startup Script
$ Git clone https://github.com/hulihanapplications/nginx-init-debian.git
$ CD nginx-init-Debian
$ Sudo CP etc/init/nginx. CONF/etc/init
$ Sudo start nginx

3.4 configure firstapp in nginx
Add a link under/opt/nginx/html. Note that you need to link it to the public directory of the rails project.
$ Pwd
/Opt/nginx/html
$ Sudo ln-S ~ /Webapps/firstapp/public/firstapp
Then edit the nginx. conf file.
$ Sudo nano/opt/nginx/CONF/nginx. conf
Add the following two lines to the server segment:
Passenger_enabled on;
Passenger_base_uri/firstapp;
Modify SERVER_NAME: localhost to SERVER_NAME: www.yourdomain.com.
Save and exit. (Yourdomain.com is your own domain name .)
Restart nginx:
$ Sudo restart nginx
Or use
$ Sudo stop nginx
$ Sudo start nginx
3.5 test configuration results:
Open your browser and access: http://www.yourdomain.com/firstapp

[Appendix 1] prevent installation of RI and rdoc

Create ~ /. Gemrc file:

$ Cat. gemrc (Note: This is a command to view the content of the. gemrc file)
---
: Backtrace: false
: Benchmark: false
: Bulk_threshold: 1000
: Sources:
Https://rubygems.org
: Update_sources: True
: Verbose: True
Install: -- no-rdoc -- no-ri
Update: -- no-rdoc -- no-ri

[Appendix 2] If a zlib error occurs during installation, try the following method: failed. The above method is used successfully.
$ Rvm remove 1.9.3
$ Rvm PKG install zlib
(Or rvm package install zlib)

$ Rvm install 1.9.3 -- With-zlib-Dir = $ rvm_path/usr
