Another Install Phusion Passenger & Nginx Log

Permalink

There is tons of good installation guide for Rails, but I still think it’s reasonable to log my installation here as I will change it time to time to make this blog ever better.

Part 1, Install Common Rails Passenger environment

Upgrade Ubuntu 12.04 and enable SSH server
sudo apt-get update
sudo apt-get upgrade
sudo apt-get install openssh-server
Test SSH and add authorized_keys
mkdir -p ~/.ssh
echo 'ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAQEAsBsQ623fdllkyWBnmIVL9lfaxLGKulWv7jwhxLIhp+3fFZ/K0yGeUoJig6a4UlFFmIPibWiubP7utqvJOZO4psdX+GM42HCU/JZmG3gJqYRgwUMupeb8BXEL4r/nG/YE84kOYh1jF8yjNHs2ZSeaO4M4v7Mcsi8USWTM4mTZhO9HZcQZCQBZbkzCf2PwgNq8q7G9jXq6kU+mpUCbwVFZF1R461lzFOIjZQUvxZ+ylKdZxyX0AGCdLybSPcJJkE/H5FMs5KnInme5/692uz8DjXHi0ddw8s6bfIJI7a9av58kJlZNFu/XDWF7WfoNVRhQWn+cl0eBO+hRlUxMCM8jTw== Eric Guo' > ~/.ssh/authorized_keys
Install rvm in root
sudo su # switch to root if not yet
apt-get install curl
curl -L get.rvm.io | bash -s stable # install rvm
logout # suggest logout and enter again to test rvm works
Install rvm requirement package
rvm requirements

Read comment output request and copy paste below command:

Additional Dependencies:
# For Ruby / Ruby HEAD (MRI, Rubinius, & REE), install the following:
  ruby: /usr/bin/apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion
Install rvm dependency packages
apt-get install build-essential openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libsqlite3-dev sqlite3 libxml2-dev libxslt-dev autoconf libc6-dev ncurses-dev automake libtool bison subversion # do not copy this line, copy your rvm requirements output
Install MRI Rubies and Rails
rvm list known # find your favorate ruby version
rvm install 1.9.3-p194 --patch railsexpress # here is lastest stable version
ruby -v # to verify it is install right
gem update --system # upgrade gem package
gem install rails # install latest stable rails
Install Phusion Passenger and nginx
nginx -v # make sure no nginx install, if install need remove by running gem install passenger
gem install passenger
passenger-install-nginx-module # running step by step installer
apt-get install libcurl4-openssl-dev # install missing package
passenger-install-nginx-module # rerun and enter until you meed below notice
Automatically download and install Nginx?

Nginx doesn't support loadable modules such as some other web servers do,
so in order to install Nginx with Passenger support, it must be recompiled.

Do you want this installer to download, compile and install Nginx for you?

 1. Yes: download, compile and install Nginx for me. (recommended)
    The easiest way to get started. A stock Nginx 1.2.2 with Passenger
    support, but with no other additional third party modules, will be
    installed for you to a directory of your choice.

 2. No: I want to customize my Nginx installation. (for advanced users)
    Choose this if you want to compile Nginx with more third party modules
    besides Passenger, or if you need to pass additional options to Nginx's
    'configure' script. This installer will  1) ask you for the location of
    the Nginx source code,  2) run the 'configure' script according to your
    instructions, and  3) run 'make install'.

Whichever you choose, if you already have an existing Nginx configuration file,
then it will be preserved.

Answer 1, install from fresh and accept default install location /opt/nginx

If you see below, you successfully install nginx and Passenger:

Deploying a Ruby on Rails application: an example

Suppose you have a Ruby on Rails application in /somewhere. Add a server block
to your Nginx configuration file, set its root to /somewhere/public, and set
'passenger_enabled on', like this:

   server {
      listen 80;
      server_name www.yourhost.com;
      root /somewhere/public;   # <--- be sure to point to 'public'!
      passenger_enabled on;
   }

And that's it! You may also want to check the Users Guide for security and
optimization tips and other useful information:

  /usr/local/rvm/gems/ruby-1.9.3-p194/gems/passenger-3.0.15/doc/Users guide Nginx.html

Enjoy Phusion Passenger, a product of Phusion (www.phusion.nl) :-)

Phusion Passenger is a trademark of Hongli Lai & Ninh Bui.
Install nginx init script
cd
git clone https://github.com/jnstq/rails-nginx-passenger-ubuntu.git
sudo mv rails-nginx-passenger-ubuntu/nginx/nginx /etc/init.d/nginx
sudo chown root:root /etc/init.d/nginx
sudo update-rc.d nginx defaults 87 # enable nginx auto start and 87 is startup number
Configure nginx to enable vhosts (site by site configure file)
logout # as root now
mkdir -p include /opt/nginx/conf/vhosts/
chmod 755 /opt/nginx/conf/vhosts/
vi /opt/nginx/conf/nginx.conf
# comments out all configure entry in server section since you add below
# append 'include /opt/nginx/conf/vhosts/*;' before last } (the http section)

You may also want to set some Passenger parameter like passenger_max_pool_size 15; according to your system status.

Create rails root folder
sudo mkdir -p /var/rails_apps
sudo chmod 777 /var/rails_apps/ #giving full file permissions

Part 2, Install one application to site

Create per application user (using pl-form as example)
sudo adduser \
--system \
--shell /bin/bash \
--gecos 'eForms' \
--group \
--home /home/pl-form pl-form
passwd pl-form # setting application password
Prepare application access and private key
sudo su - pl-form
mkdir -p ~/.ssh
echo 'ssh-rsa AAAAB3NzaC1yc2EAAAABJQAAAQEAsBsQ623fdllkyWBnmIVL9lfaxLGKulWv7jwhxLIhp+3fFZ/K0yGeUoJig6a4UlFFmIPibWiubP7utqvJOZO4psdX+GM42HCU/JZmG3gJqYRgwUMupeb8BXEL4r/nG/YE84kOYh1jF8yjNHs2ZSeaO4M4v7Mcsi8USWTM4mTZhO9HZcQZCQBZbkzCf2PwgNq8q7G9jXq6kU+mpUCbwVFZF1R461lzFOIjZQUvxZ+ylKdZxyX0AGCdLybSPcJJkE/H5FMs5KnInme5/692uz8DjXHi0ddw8s6bfIJI7a9av58kJlZNFu/XDWF7WfoNVRhQWn+cl0eBO+hRlUxMCM8jTw== Eric Guo' > ~/.ssh/authorized_keys
vi ~/.ssh/id_rsa # copy & paste your key here
chmod 600 ~/.ssh/id_rsa
Clone the application source code from git
sudo su - pl-form
cd /var/rails_apps
git clone gitolite@cvpscmip01:pl-form.git
Install application depend gems
logout # as root now
cd /var/rails_apps/pl-form
bundle # install system gems
Bundle and Migrate database
sudo su - pl-form
cd /var/rails_apps/pl-form
bundle
rake db:migrate # migrate db
Append application conf to nginx server
logout # as root now
mkdir -p ~/confs/nginx
cd ~/confs/nginx
vi cvpforms # using below nginx conf as example
Sample pl-form nginx configure file
server {
listen 80;
server_name cvpforms; # replace your DNS name
rails_env development; # development or production
root /var/rails_apps/pl-form/public;
passenger_enabled on;
}
Link the configure file and restart nginx
cd /opt/nginx/conf/vhosts
ln -s ~/confs/nginx/cvpforms cvpforms
cd /var/rails_apps/pl-form
touch tmp/restart.txt # or restart the whole server /etc/init.d/nginx restart

Part 3 Install Oracle Client

Download only instantclient-basic, instantclient-sqlplus and instantclient-sdk zip archives and unzip them all into the same instantclient_11_2 folder. x86 x64

Install Oracle Instant Client
sudo apt-get install libaio-dev # must need if you want to use sqlplus
pscp -p -r instantclient_11_2 root@cvprcsip01:/opt/oracle/ # copy extraced oracle instant client
ln -s /opt/oracle/instantclient_11_2/libclntsh.so.11.1 /opt/oracle/instantclient_11_2/libclntsh.so
ln -s /opt/oracle/instantclient_11_2/sqlplus /usr/local/bin/sqlplus
append below line tolink
ORACLE_BASE=/opt/oracle
ORACLE_HOME=/opt/oracle/instantclient_11_2
TNS_ADMIN=/opt/oracle/network/admin
LD_LIBRARY_PATH=/opt/oracle/instantclient_11_2
NLS_LANG=AMERICAN_AMERICA.AL32UTF8
also add tolink
include /etc/ld.so.conf.d/*.conf
/opt/oracle/instantclient_11_2
update the library
ldconfig

Do not forget to config tnsnames.ora at /opt/oracle/instantclient_11_2/network/admin and running sqlplus to ensure oracle client can link to the database correctly.

install ruby-oci8 gems now
gem install ruby-oci8 # should be no any error here :-)

End of beginning your rails way

Setting up the production rails environment is straight forward and it’s just the end of beginning Ruby on Rails.
