Apache Server installation and deployment of rails applications using the passenger plugin

A small example can be deployed on rails ' webrick, and it will take Apache to move backwards.

Installing the Apache server

command is sudo apt-get install apache2

Installing the Passenger plugin

The installation is not ready for immediate use, because you want to run the Rails app and install the plugin passenger for the Apache server.

Passenger is a gem package and the installation command is gem install passenger

Passenger integrated into Apache

Execute the command passenger-install-apache2-module and enter the installer.

The procedure also gives a solution. Although they are given separately, we can do it together. Your environment may not be the same as mine, follow the above tips to 90%.

Perform the Passenger-install-apache2-module installation again, and after the compilation is complete, a successful prompt is given. It is also required to place the following in the Apache configuration file.

12345678910111213

The Apache 2 module was successfully installed.Please edit your Apache configuration file, and add these lines:   LoadModule passenger_module /home/abbuggy/.rvm/gems/ruby-1.9.2-p320/gems/passenger-3.0.18/ext/apache2/mod_passenger.so   PassengerRoot /home/abbuggy/.rvm/gems/ruby-1.9.2-p320/gems/passenger-3.0.18   PassengerRuby /home/abbuggy/.rvm/wrappers/ruby-1.9.2-p320/ruby After you restart Apache, you are ready to deploy any number of Ruby on Railsapplications on Apache, without any further Ruby on Rails-specificconfiguration!Press ENTER to continue.

Apache configuration files are located in/etc/apache2/httpd.conf, edited and added. So far, httpd.conf has been like this.

Deploy Rails Apps

I want to visit my example site through an address similar to "localhost/simple-cms", and more sites can follow the form

Localhost/site1

Localhost/site2

The format.

First you have to configure a base directory, which is the root directory of Apache.

Add the following configuration to httpd.conf, set/var/www as the root of the web and go back to the directory where you want to place each site.

1234567

<VirtualHost*:80>      ServerName localhost      DocumentRoot /var/www      <Directory/var/www>         Allow from all      </Directory></VirtualHost>

Next, hang a specific site under the Web root directory, such as this simple-cms. or configure it to/etc/apache2/httpd.conf, the next four lines are added. /simple-cms is the access address relative to the above localhost

123456789101112

<VirtualHost *:80>   ServerName localhost   DocumentRoot /var/www   <Directory/var/www>      Allow from all   </Directory>       RailsBaseURI /simple-cms   <Directory/var/www/simple_cms>      Options -MultiViews   </Directory></VirtualHost>

/var/www/test_site is a soft connection that points to the public directory in the development environment.

1	sudo ln -s /home/abbuggy/workspace/simple_cms/public  /var/www/simple-cms

However, when I configure myself, I am wrong, always prompt "We ' re sorry,but something went wrong!" The solution was finally found near the edge of the crash. "The DEFAULTRAILS_ENV environment in which deployed Rails Applicationsare run, is" production ". You can change this by changing therailsenv configuration option. "-From phusion passenger users Guide

That is, the default is the production environment, if you use the development environment when debugging, you need to add a line railsenv development in the Apache configuration file, so the correct configuration is.

12345678910111213

<VirtualHost*:80>   ServerName localhost   DocumentRoot /var/www   <Directory/var/www>      Allow from all   </Directory>      RailsBaseURI /simple-cms   RailsEnv development   <Directory/var/www/simple_cms>      Options -MultiViews   </Directory></VirtualHost>

Restart the Apache,sudo service apache2 restart to access Localhost/simple-cms successfully.
