how to deploy a padrino project into a server

To deploy a padrino project with passenger and nginx to a new server,it should be a easy job,but I did not use nginx before,and It seems quite a lot of problems came out.

This article may be useful for those who get the same probelms.

First we should install some necessary linux libs.

sudo apt-get install build-essential bison openssl libreadline6 libreadline6-dev curl git-core zlib1g zlib1g-dev libssl-dev libyaml-dev libxml2-dev libxslt-dev autoconf libc6-dev zlib1g-dev libssl-dev build-essential curl git-core libc6-dev g++ gcc

then install RVM and loading RVM ENV.

bash < <(curl -s https://raw.github.com/wayneeseguin/rvm/master/binscripts/rvm-installer)

Loading rvm ENV

source .bashrc

use rvm info or type rvm|head -n 1 to check if the rvm installed successfully.

install necessary ruby libs.

sudo aptitude install build-essential bison openssl libreadline5 libreadline5-dev curl git-core zlib1g zlib1g-dev libssl-dev libsqlite3-0 libsqlite3-dev sqlite3 libxml2-dev libmysqlclient-dev

install ruby in rvm

rvm install 1.9.3

then rvm list ,got

get Problem :

Default ruby not set. Try ‘rvm alias create default ruby’.

solution :

rvm alias create default 1.9.3

then add 1.9.3 as default:

rvm use 1.9.3 --default

add passenger as ruby version 1.9.3

rvm 1.9.3 –passenger

but get Note message : NOTE: If you are using Passenger 3 you no longer need the passenger_ruby, use the wrapper script for your ruby instead (see ‘rvm wrapper’)

No need to take care of this Note,cause the ENV will be setted by itself.

rvm use 1.9.3 default.

then install passenger and nginx with Gem and rvmsudo

gem install passenger

rvmsudo passenger-install-nginx-module

when we install the passenger-install-nginx-module , there comes another problem ,

Problem:

Curl development headers with SSL support… not found

Solution:

just go on ,cause it will prompt us that which libs we need and should be installed

To install Curl development headers with SSL support: Please run apt-get install libcurl4-openssl-dev or libcurl4-gnutls-dev, whichever you prefer.

Solution:

sudo apt-get install libcurl4-openssl-dev

try to get “passenger start” with it’s command:passenger start,

but alse got problems:

Problem three

passenger start

”=============== Phusion Passenger Standalone web server started ===============” PID file: /home/ubuntu/humanoid/tmp/pids/passenger.3000.pid Log file: /home/ubuntu/humanoid/log/passenger.3000.log Environment: development Accessible via: http://0.0.0.0:3000/

You can stop Phusion Passenger Standalone by pressing Ctrl-C.: pid=32362 thr=13093500 file=utils.rb:176 time=2012-05-03 01:02:55.601 Exception PhusionPassenger::UnknownError in PhusionPassenger::Rack::ApplicationSpawner (undefined method <<' for nil:NilClass (NoMethodError)) (process 32362, thread #<Thread:0x000000018f94f8>) from /home/ubuntu/.rvm/gems/ruby-1.9.2-p320/gems/rack-flash-0.1.2/lib/rack/flash.rb:20:inrun’ :

I don’t know how to fix this problem,try to restart the nginx,

comes other problems

restart ngnix

sudo /etc/init.d/nginx start

Segmentation fault ,I tried to find out what the problems were ,but fail, the solutions which google gives can’t help.

so I ask kevin and Yasith for help.

It may arise by diffrent versions of passenger and nginx ,so sooyoung create anouther new server ,and start to install again,Segmentation problem disappear.

Then I clone the project from the server.

First I should create a key and add it to the server system.

how to add ssh key document.click the link http://help.github.com/mac-set-up-git/

then git clone the code,git clone "code address"

we cannot run the project without database,so install Mysql.

install mysql

sudo apt-get install mysql-client mysql-server

and install padrino by Gem.

gem install padrino

we should bundle install, but some small problems happen,so after bundle install,just use bundle update

bundle install and bundle update.

create the database for this project.

bundle exec padrino rake ar:create

problem

rake aborted! uninitialized constant Mysql

Tasks: TOP => ar:create (See full trace by running task with –trace)

so bundle exec padrino rake ar:create --trace

Can’t connect to local MySQL server through socket ‘/tmp/mysql.sock’

then I found the database ENV has another link,just ln it to that which the server needs.

Solution

ln -s /var/run/mysqld/mysqld.sock /tmp/mysql.sock

Try again,creates migrations

problem

rake aborted! undefined method name' for nil:NilClass

/home/ubuntu/.rvm/gems/ruby-1.9.3-p194/gems/activerecord-3.0.12/lib/active_record/schema_dumper.rb:44:in header'

/home/ubuntu/.rvm/gems/ruby-1.9.3-p194/gems/activerecord-3.0.12/lib/active_record/schema_dumper.rb:26:in dump'

/home/ubuntu/.rvm/gems/ruby-1.9.3-p194/gems/activerecord-3.0.12/lib/active_record/schema_dumper.rb:21:in dump'

/home/ubuntu/.rvm/gems/ruby-1.9.3-p194/gems/padrino-gen-0.10.1/lib/padrino-gen/padrino-tasks/activerecord.rb:244:in block (4 levels) in <top (required)>'

/home/ubuntu/.rvm/gems/ruby-1.9.3-p194/gems/padrino-gen-0.10.1/lib/padrino-gen/padrino-tasks/activerecord.rb:243:

solution

then open the file,

home/ubuntu/.rvm/gems/ruby-1.9.3-p194/gems/activerecord-3.0.12/lib/active_record/schema_dumper.rb :44

add .nil? to jump this problem.

if stream.respond_to?(:external_encoding).nil? stream.puts “# encoding: #{stream.external_encoding.name}” end

start nginx again

sudo /etc/init.d/nginx start

problem

Starting Nginx Server…

nginx: emerg bind() to 0.0.0.0:80 failed (98: Address already in use)

solution:

stop other nginx ,use bin ,not init.d/nginx

sudo /opt/nginx/sbin/nginx -s stop

start nginx again

problem

undefined method ’«’ for nil:NilClass

thanks to the article,https://github.com/nakajima/rack-flash/issues/8

Confirmed with these:

Using bundler (1.0.21) Using rack (1.3.5) Using rack-flash (0.1.2) Using sinatra (1.3.1) ruby 1.9.3p0

solution

degrade the versions of rack,rack-flash,sinatra

But another problem comes,

problem

Passenger encountered the following error:

The application spawner server exited unexpectedly: Connection closed

Exception class:

PhusionPassenger::Rack::ApplicationSpawner::Error

It is hard to find out the solution for this problem, http://code.google.com/p/phusion-passenger/issues/detail?id=590,this article may be helpful, but after my trying,it seems not.

In fact,I don’t know why I can meet these quite a lot of problems,finally,another new server was created to deploy for the project,with kevin,yasith,sooyoung’s help, It works. I should ask them for steps and attention about deploying this padrino project on Monday.
