What dir should I deploy Rails apps into?

What would be a reasonable and logical directory into which to deploy my production Rails apps on a Linux system?

Some candidates...

/var/rails  <= There's a /var/www so this would be consistent with that 
               pattern. But I.T. guys have complained about stuff in /var 
               before.

/home/my_home_dir/rails  <= OK, not /var, but I'm not the only developer. 
                            Seems like it really ought to be a systemwide
                            location.

/home/rails  <= I don't know. That just seems weird.

/rails  <= Seems even weirder.

What is the least astonishing, most normal thing to do here?

(Background info -- a Rails app is a bunch of server side code written in Ruby along with a public dir containing JavaScript, CSS, and maybe a little HTML. The public dir is mapped to an Apache vhost. Apache handles the Ruby code through a module called Passenger or mod_rails.)

Thanks for the help, all. I think I'm going to go with /opt/deployed_rails_apps. (I like long, expository directory names, and tab completion.) /var/... is also a good place, but I've gotten stern grumbling from I.T. when I tried to deploy stuff there. If it were my own machine I might go with /var or /srv.

Solution 1:

I think /opt would be the place for an application like this. I agree with following the FHS as suggested by chmeee, but I don't agree that a Rails app is a service per se.

Solution 2:

You may want to follow the Filesystem Hierarchy Standard (FHS) and place it in

/srv : Data for services provided by this system

EDIT:

I wouldn't place it in /opt:

/opt : Add-on application software packages

It's purpose says:

/opt is reserved for the installation of add-on application software packages.

A package to be installed in /opt must locate its static files in a separate /opt/ or /opt/ directory tree, where is a name that describes the software package and is the provider's LANANA registered name.

I don't think a developed application is a 'software package'.

The rationale for /srv is

This main purpose of specifying this is so that users may find the location of the data files for particular service, and so that services which require a single tree for readonly data, writable data and scripts (such as cgi scripts) can be reasonably placed.

I understand that a rails app is a cgi script and should be placed in /srv.
