Rails Deployment(1)modrails

1. Install Passenger
>sudo gem install passenger

>sudo passenger-install-apache2-module

This is the console output of the command:
checking for required software...
GNU C++ compiler... found at /usr/bin/g++
Curl development headers with SSL support... not found
OpenSSL development headers ... not found
Zlib development headers ... found
Ruby development headers...found

Apache 2... found at /usr/sbin/apache2
Apache 2 development headers... not found
Apache Portable Runtime (APR) development headers... not found
Apache Portable Runtime Utility (APU) development headers ... not found

I need to install all the related softwares.

>sudo apt-get install libcurl4-openssl-dev  or >sudo apt-get install libcurl4-gnutls-dev
>sudo apt-get install libssl-dev
>sudo apt-get install apache2-prefork-dev
>sudo apt-get install libapr1-dev
>sudo apt-get install libaprutil1-dev

For the standalone version, we can use this command:
>cd /home/luohua/work/projectname/
>passenger start

That is ok, we can visit http://localhost:3000 to test the websites now.

2. Configure and run with apache2
And we can also put the server on apache together.
Please edit the apache configuration file:

>vi httpd.conf

LoadModule passenger_module /usr/lib/ruby/gems/1.8/gems/passenger-3.0.8/ext/apache2/mod_passenger.so
PassengerRoot /usr/lib/ruby/gems/1.8/gems/passenger-3.0.8
PassengerRuby /usr/bin/ruby1.8

Deploying a Ruby on Rails application: an example

Suppose the rails application in /somewhere.
Add a virtual host to my apache configuration file and set its DocumentRoot
to /somewhere/public:

>cd /etc/apache2/sites-available
>vi projectname

<VirtualHost *:81>
ServerName www.yourhost.com
DocumentRoot /somewhere/public #be sure to point to public
<Directory /somewhere/public>
  AllowOverride all
  Options -MultiViews
</Directory>
</VirtualHost>

>cd /etc/apache2/sites-enabled
>ln -s ../sites-available/projectname

when I visit the URL http://localhost:81, I got these error messages:
syntax error, unexpected ':', expecting '}' format.json { render json: @accounts }

After I change the syntax from render json: @accounts to render json => @accounts. That is fine then.
