multiple rails app in apache using passenger on centos - ruby-on-rails

Question

I have been following this guide on how to run a rails app in an apache server. I have successfully made it work but with only 1 rails app running. I tried editing the httpd.conf with 2 virtual hosts.
LoadModule passenger_module /usr/local/rvm/gems/ruby-2.1.1/gems/passenger-4.0.42/buildout/apache2/mod_passenger.so
PassengerRoot /usr/local/rvm/gems/ruby-2.1.1/gems/passenger-4.0.42
PassengerDefaultRuby /usr/local/rvm/wrappers/ruby-2.1.1/ruby
RackEnv development
<VirtualHost *:3000>
ServerName ***.***.***.***
# !!! Be sure to point DocumentRoot to 'public'!
DocumentRoot /var/www/html/testapp/public
<Directory /var/www/html/testapp/public>
# This relaxes Apache security settings.
AllowOverride all
# MultiViews must be turned off.
Options -MultiViews
</Directory>
</VirtualHost>
<VirtualHost *:3001>
ServerName ***.***.***.***
# !!! Be sure to point DocumentRoot to 'public'!
DocumentRoot /var/www/html/testapp2/public
<Directory /var/www/html/testapp2/public>
# This relaxes Apache security settings.
AllowOverride all
# MultiViews must be turned off.
Options -MultiViews
</Directory>
</VirtualHost>
but it seems only port 3000 is working.

Answer 1

You'll need to make sure you have the other server set up on port 3001
Port
The problem you'll have is that you're capturing the same request (to same domain / IP), except listening on different ports. If you want to access the different sites, therefore, you have to access by the ports you define.
#app1 -> ***.***.***.***:3000
#app2 -> ***.***.***.***:3001
This should give you the ability to access your Rails apps respective to your apache implementation.

VirtualHosts
If I were you, I'd either create a virtualhost with a directory setup:
/etc/apache2/apache2.conf
<VirtualHost *:80>
ServerName [ip]
# !!! Be sure to point DocumentRoot to 'public'!
DocumentRoot /apps/public
#Other App
Alias /app1 /apps/app1/public
<Location /reach>
PassengerAppRoot /apps/app1/public
RackEnv production
RackBaseURI /app1
</Location>
#Other App
Alias /app2 /apps/app2/public
<Location /apps>
PassengerAppRoot /apps/app2/public
RackEnv production
RackBaseURI /app2
PassengerFriendlyErrorPages off
</Location>
</VirtualHost>
This will give you a much simpler way to handle the incoming requests:
***.***.***.*** -> IP index
***.***.***.***/app1 -> application 1
***.***.***.***/app2 -> application 2
I'd be much more tempted to use the above setup than your own.
Further, you may also wish to actually deploy separate virtual hosts for your applications. The above example details how you'd introduce different directories for your different apps - if you'd prefer to create different virtualhosts, here's what you can do:
#etc/apache2/sites-available/default (standard site - I'd recommend static)
<VirtualHost *:80>
ServerAdmin webmaster#localhost
DocumentRoot /var/www
<Directory />
Options FollowSymLinks
AllowOverride None
</Directory>
<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all
</Directory>
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
<Directory "/usr/lib/cgi-bin">
AllowOverride None
Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Order allow,deny
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
#etc/apache2/sites-available/app1
<VirtualHost *:80>
ServerName yourdomain.com
ServerAlias yourdomain.com
DocumentRoot /apps/app1/public
<Directory /apps/app1/public>
Allow from all
Options -MultiViews
</Directory>
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
<Directory "/usr/lib/cgi-bin">
AllowOverride None
Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
Order allow,deny
Allow from all
</Directory>
ErrorLog ${APACHE_LOG_DIR}/error.log
# Possible values include: debug, info, notice, warn, error, crit,
# alert, emerg.
LogLevel warn
CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>
Don't forget to symlink these to your /etc/apache2/sites-enabled folder:
> $ ln -s /etc/apache2/sites-available/app1 /etc/apache2/sites-enabled/app1
