Ruby on Rails on OSX Server

Has any one built or have instructions for installing Ruby on Rails on OSX Server 10.4?
Do these instructions still apply:
http://hivelogic.com/narrative/articles/ruby-rails-mongrel-mysql-osx
And can it play alongside Apache if you use Mongrel as the web server?

I have been trying for the last couple of weeks to get Ruby on Rails running on OSX Server as well. I followed the instructions on the site you refer to. The whole installation proceeds just fine, I can run my RoR sites locally by running scripts/server, but when trying to access the web site I get a 403 error and the log says "Directory index forbidden by rule".
I have followed directions from other sites regarding: installing and activating the fastcgi module, setting access rights to various folders and files, modifying the httpd.conf file to allow overwrite all and access to indexes,... No progress. I still can't get the RoR site to work.

Arch is currently not ideal as a Ruby on Rails server

Hi all. This is my first post. I hope I am posting in the right place. I have just started using Arch, and I love it! I have used many server distros in the past, have real experience in production environments, and I'd love to use Arch for any servers I need in the future.
There's a problem, though. Best as I can tell, the only version of Ruby available on Arch right now is version 1.9.1. While that's the latest stable, for certain reasons it is not the recommended version on which to run the popular web framework, Ruby on Rails, which I make my living developing in. You can see that for yourself here:
http://rubyonrails.org/download - "We recommend Ruby 1.8.7 for use with Rails."
I'm sure this isn't the first time there have been popular versions of software despite there being later releases. People are often slow to adapt in production environments. However, I couldn't even find a ruby18 package, or anything like that.
I'm not requesting years-old stability or anything absurd like that. In general, I like having the newest software. But in practice, it's sometimes prudent to prefer the next-to-newest software.
In addition, the ruby package installs "rubygems", a separate package management system for Ruby analogous to CPAN in Perl. The problem is, it installs an old version of rubygems, 1.3.1, which is so old it doesn't work. The latest stable version of this is 1.3.7, and version 1.3.2 is required for Rails. I was able to upgrade it using the special rubygems updater ("gem update --system") but I worry this will conflict with pacman, and it shouldn't be necessary.
In short: please upgrade rubygems, and please provide a 1.8 version of the ruby package.
All of the packages I'm discussing were based on the present pacman versions as of this post. Thanks for your help and for the great distro!

It may end up being just for you, or others may also find it useful and help you out, but either way you get what you want, and Arch gets the "community support which it does not have". There have been numerous examples of this over the years.
I understand your point, but using the AUR dramatically diminishes the ease of use from the whole setup. I have to manually download the PKGBUILD and any patch files, build it, install it, and then manually keep track of updates, manually delete the installed files (there is no uninstall) and then repeat the process. While it's great that the AUR is there for specialized interests, it seems that things from the AUR should be incorporated into the official packages if they have enough support. My problem is mainly in the selection of "official packages", and the deference to the AUR anything that doesn't meet the strict and dare I say impractical requirements for inclusion therein. There needs to be more respect for widely-used earlier branches, and there needs to be respect for upstream packaging problems such as the rubygems one. And I am here, in the community, voicing my opinion on this issue, but I cannot change the official packages or the philosophy by sheer force of individual will. It's going to require that people consider what I have to say, and consider what Arch should be.
Ruby 1.8, as with many other major releases, continued in its development and had point releases even after Ruby 1.9 came out. Despite being official, these releases are not available via pacman. It remains the dominant form of Ruby in use today, and probably will be for another year or so.
Consider the release of MySQL 5.0. Would you expect everyone to switch from 4.1 immediately to 5.0 once they released their first stable? Or shouldn't it be possible to stay on the prior major version branch and make the conscious decision to switch? At some point, the keyword "mysql" should switch to the newer branch, and the old one should be maintained as mysql4.1 for legacy support for a while; but this should be a while in, after the tide has turned in its favor. I'm certain something like this is already the policy for the Linux kernel, for instance. I'm just asking it also be applied to Ruby.
Instead, I'm relegated as a minority interest to the AUR ghetto. I think Rails and its philosophy has a lot in common with Arch Linux, and I've heard other Rails people speaking of it favorably. They are both focused on ease of use. They could be compatriots, and Arch could benefit from the friendship. Both communities are often interested in using brand new software, when appropriate. Rails is ruthless with its deprecation. But the community for Arch Linux needs to decide whether it can be useful as a young, innovative new server distro for practical use, or whether it's beleaguered by the philosophy that "true" "critical" server distros use "stable" archaic software and sacrifice maintainability, bug fixes, new features, and simple pleasure in the process, and therefore Arch has no place amongst their anachronistic pantheon, doomed to dwell underground forever with Gentoo and the other thoughtful playthings.
I was surprised to find myself being criticized for suggesting I would use Arch as a production server. I think it has the chops, it just needs to commit to the purpose. Don't be defeatist, there are a wide variety of possible production scenarios, many which use fresh new software; let server admins make the decision whether or not Arch is capable of the job.
As for variations on upstream releases (such as fixing this rubygems version problem), I think the best solution is that pacman should have something that allows automatic building, installing, upgrading and uninstalling of community packages -- maybe even binary variants -- so that users can have the ease of use, but also realize they are using something that differs from the official upstream releases. A convention to install in /opt or /usr/local/ would further the mental divide and diminish the risk.
Please understand my criticism comes with respect, and a desire to use Arch. I ache every time I check the replies, knowing I've likely offended people. I apologize for the length of this post. The truth is, if I can't use Arch as a production server, I don't see any point to it. I am an outsider looking in, sharing my thoughts, and I don't expect they will be received warmly, but it would be great if they were. However, so far the impression I get from this thread is that Arch has no interest in being a production server, sees it as a sideline, implausible interest in conflict with its theory.

OSX Server Ruby device manager hogging RAM

I am running OSX Server (10.8.4 Server 2.2.1) on an iMac 8,1 (2.66 GHz Intel Core 2 Duo 6 GB RAM). In looking at the Activity Monitor I have 13 and sometimes more "ruby _devicemgr" Processes running that use about 75 MB of RAM each. That is close to 1/6 th of my total RAM. Is this normal? Are there settings that I can use/not use to reduce these processes? Since the Tech Specs only call for 2 GB of RAM (I know it's a minimum req) it seems a bit strange that ruby should be getting so much RAM.

In case anyone else comes here looking for a solution,and the above doesn't work for them. I was trying to resolve the repeated instances of this in my log file, plus the effects of not having postgres running. I'm on OS X Lion Server, 10.7.5, on an XServe.
org.postgresql.postgres[18789]: postgres_real cannot access the server configuration file "/var/pgsql/postgresql.conf": No such file or directory
com.apple.launchd[1] (org.postgresql.postgres[18789]): Exited with code: 2
com.apple.launchd[1] (org.postgresql.postgres): Throttling respawn: Will start in 10 seconds
I ran these commands:
sudo chmod 777 /var
sudo mv /var/pgsql /var/pgsql.OLD
sudo -u _postgres /usr/bin/pg_ctl initdb -D /var/pgsql
sudo chmod 755 /var
This initialized the postgres setup and everything seems to be running happily now.

Ruby on Rails Concurrent program registration in EBS 11i

hi everyone
I'm trying to see if it is possible to register a Ruby on Rails concurrent program in Oracle E-business Suite 11i applications. We have Ruby on the Rail program we are using to create a GL Daily Rates file into one of our Custom top directory. Our intention is to create a request set that includes this Ruby on Rails program and SQL*Loader program that loads the data into staging table before data is uploaded to the GL_Daily_Rates_Interface.
I have seen that the execution method for Ruby on Rails does not exist in 11i and have tried to use perl but without success.
Any help will be much appreciated.
Thanks in advance.

New wiki page on Ruby on Rails

Hi,
Just wanted to let you know that I created a Ruby on Rails page on the
wiki. It's not really long but the basis is there to quickly set up a
rails application.

As always, please feel free to comment and edit the wiki.

Hi,
It is a really nice idea. Maybe the page ought to serve as a hub for other articles.
A couple of comments on sharing medias:
* I have not been very happy with upnp. I used it for a while when I had a Synology NAS, but the fact that it seemed to rely on some kind of index made it less attractive. Samba has treated me nice; it always works (as oppose to "real" Windows shares which is a drag to setup). I use samba for sharing videos and pictures to XMBC4Xbox.
* For streaming live audio output, i.e. what is playing *right now* on my laptop to my stero, I have found a combo of icecast, pulseaudio and gstream to work nice. For serving static audio files I use squeezeboxserver. Had I used a Sonos sound system I would have used Samba again.
* For PS3, which is a somewhat limited device, there is a nice java application that takes care of everything.
* What I really miss is some way to preserve metatags when downloading video podcasts. To me it does not matter much at the moment as xbmc does not support local rss feeds. . .
I could add some comments on some of the above if you think it fits into your article.

[SOLVED]Ruby on Rails won't run with apache/passenger

Hi I want to run Redmine, a Ruby on Rails application, on a personal server using MariaDB as the database and Apache with the Phusion Passenger module as the application platform. So far I am able to run Redmine with the default WeBrick server, but if I try to run it via Apache (http://192.168.1.5/redmine) I just get the directory index of /usr/share/webapps/redmine. I've been running various php webapps using this apache installation without issues but my unfamiliarity with Ruby on Rails makes me unsure how to fix this. If I create a Ruby on Rails test application as described at https://wiki.archlinux.org/index.php/Ru … figuration I get the same issue.
Using the arch wiki articles on Ruby on Rails and Redmine, This is basically how I installed things:
$ yaourt -S ruby1.9 rubygems1.9 nodejs redmine
# gem-1.9 install rails
# gem-1.9 install passenger
/opt/ruby-1-9/ and subfolders ended up having no read/exexute permissions for 'other', probably because of my umask settings, so I changed the permissions, also because apache runs as user/group 'apache'.
Ran the script that installs the passenger apache module:
# /opt/ruby1.9/bin/passenger-install-apache2-module
added to httpd.conf:
LoadModule passenger_module /opt/ruby1.9/lib/ruby/gems/1.9.1/gems/passenger-4.0.5/libout/apache2/mod_passenger.so
PassengerRoot /opt/ruby1.9/lib/ruby/gems/1.9.1/gems/passenger-4.0.5
PassengerDefaultRuby /opt/ruby1.9/bin/ruby
ServerName arch-server
DocumentRoot /usr/share/webapps
<Directory "/usr/share/webapps">
# This relaxes Apache security settings.
AllowOverride all
Order allow,deny
Allow from all
# MultiViews must be turned off.
Options -MultiViews
</Directory>
I checked if the passenger module is loaded, and judging from /var/log/httpd/error_log that seems the case:
[ 2013-07-03 22:52:22.8947 28902/b7407700 agents/Watchdog/Main.cpp:440 ]: Options: { 'analytics_log_user' => 'nobody', 'default_group' => 'nobody', 'default_python' => 'python', 'default_ruby' => '/opt/ruby1.9/bin/ruby', 'default_user' => 'nobody', 'log_level' => '0', 'max_instances_per_app' => '0', 'max_pool_size' => '6', 'passenger_root' => '/opt/ruby1.9/lib/ruby/gems/1.9.1/gems/passenger-4.0.5', 'pool_idle_time' => '300', 'temp_dir' => '/tmp', 'union_station_gateway_address' => 'gateway.unionstationapp.com', 'union_station_gateway_port' => '443', 'user_switching' => 'true', 'web_server_pid' => '28901', 'web_server_type' => 'apache', 'web_server_worker_gid' => '1001', 'web_server_worker_uid' => '1006' }

'apachectl configtest' gives 'Syntax OK'.
I followed the wiki on redmine (https://wiki.archlinux.org/index.php/Redmine), chose to use "bundle install" to install the required gems with only a 'production' environment. What worried me is that those gems are now in /root/.gems while the webserver runs as user 'apache'.
I can run Redmine at 192.168.1.5:3000 without errors using:
# ruby script/rails server webrick -e production
But if I kill it and try via apache http://192.168.1.5/redmine I get a directory content listing.

Ruby on Rails environment

I have tried the Apple tutorial and Adam Blackbourne's book and website and still cannot get a functional environment started so that I can develop using Ruby on Rails. I get Ruby installed, Textmate installed, and then seem to get bogged down with Textmate and sql. I seem not to have mysql properly installed but I can't figure out what's wrong. Both these sources above refer to some great package call Locomotive that is "the golden path..." but it has been withdrawn by its author. Any ideas on how to proceed? What sources are available?

Hi,
I'm not sure what your stated problem is here? It seems you are describing problems with Ruby on Rails on Leopard and coincidentally with mysql based on the Apple tutorial; are these one problem or two? Please note that the tutorial is describing running mysql on server which is part of the 10.5 server package.
I have been running Rails 2.0.2 on Leopard client which I loaded following the tutorial (once I loaded Xcode 3 on the client as well). Since Rails 2.0 comes with sqlite3 as its default database, you can be up and running on 10.5 client in short order and save your mysql for deployment. In my case I also have 10.5 Server and have been testing with Rails and reverse proxies while operating in development mode (with sqlite3). When I start porting over to Server, mysql is a service on server and has a unique configuration. So the tutorial may not be applicable if you are using it with a mysql standard type install. You can read about the server install environment of mysql at
http://docs.info.apple.com/article.html?path=ServerAdmin/10.5/en/c6ws25.html
Actually, Ruby on Rails 2.0.2, TextMate and Ruby-Debug form a great environment for development. Not quite an IDE on 10.5 but almost there.
Hope this helps,
Harry

Ruby on Rails, Apache2, OS X 10.5

I cannot get Ruby on Rails to work on Apache while running OS X 10.5. I've searched the web for configurations that say they will allow ruby to work, with out any luck. Any help would be greatly appreciated.

Thanks for both replies.

Ruby on Rails

I tried to follow the Ruby on Rails example post by Apple but it simply didn't work. I got the server started but the SQL migration didn't work. Has anybody made this work or been able to get through the "tutorial?"

Thanks. It is hard to describe exactly what doesn't work, but I will try. I get to the point in the tutorial where the server is up and running, I get Textmate running, but I keep having trouble with MySQL. I have installed MySQL 5.0.5 but at one point I got a screen that said I was using SQLite3. I think that came with some Apple package. I don't know how to "look at that particular section of the config/database.yml file." Nor how to modify it per the tutorial. "mysqladmin" commands generate an error message saying they can't be found. It seems that I have environmental issues. Of course, the "golden path installation guide," Locomotive, has been removed from circulation. So, I think that the tutorial assumes things will be done for you by installing Locomotive and that can't happen. I can't even get to the sample application.
Does this help in analyzing my problem?

Sending BitmapData to Ruby On Rails

Hi
I have a project that has a SAVE button that on click needs to save a PNG file of an area of the stage (or a MC if that is easier) to a server and put and entry for said file into a database. The database end of things is going to be handled by the web developer so not a concern for me.
I found an example on the web that uses PHP to write the PNG file to a remote drive, and the ActionScript just needed to call a PHP page with POST variables to execute the save. I cannot however find any examples of how to do this with Ruby On Rails. Would the methodology be the same; call a URL to a Ruby script and send the variables via POST? In which case the ActionScript side of things would essentially be the same as for the PHP method? Or does using RoR require some other means of executing this kind of function?
Many thanks for any advice. I'm out of my league on this one
cheers
adam

I would say that YES the method should be the same -- at least inasmuch as you are POSTING enough data to make the image to your server. Ruby should be able to find the bitmap data in POST.

Ruby one rails Web application

Hi, I have been working on setting up the ruby on rails application for web review that apple sent to my boss and I had some questions if people knew how to fix a few certain problems. I am not very proficient when it comes to ruby or rails, but I don't have the money to hire some one to do this for me, so I am trying to teach my self.

[Priority 1] Can we convert the QT served files to be streamed rather than 'wait while downloading"? If we can't stream, we need a progress bar to track the download pace.
- [Priority 2] Web-based upload tool
- [Priority 3] Who/When an event happens: specifically, who approved the clip & when (on the website)?
- [Priority 4] Clip length displayed next to the clips.
- [Prpriority 5]simple log in and password
I know this is a lot to ask and I am not asking any one to go out of there way to figure anything out, just if any one know any reading material or tutorials and can point me in the right direction it would be appreciated.
thank you

Unless you want to learn and support a Ruby on Rails application like the one you are trying to implement, which will work, but will never be officially supported by Apple.
I would recommend you take a look at services like:
Media Silo
http://www.mediasilo.com/fcs
Wiredrive
http://www.wiredrive.com
They do very excellent jobs of offering Robust review and approval workflows.

Solaris 10, Ruby on Rails, Core Dumps

I am not very savvy with Solaris administration and we are having issues with configuring our system to run Ruby on Rails applications. We opted to use the Coolstack framework for our environment, thankfully without many hiccups. That said, our applications load but core dump during the second page load.
At this point, I'm not sure if it's our recent switch to Coolstack that is causing the problem. We've also worked to get a Mongrel cluster up and running, so that could also be the culprit.
What I'm looking for really is advice on how to pin down what the error is. I've learned about pstack to deal with the core dump file, but I'd have a better time understanding Chinese than that output. I also read about gdb and dbx, neither of which appear to be installed on our system. A strings on the file, another recommendation I found, spits out a bunch of gibberish.
How can I move forward in discovering the problem?

I'm having the exact same problem with my Solaris server. I can't seem to get any form of Rails running on the system, and pages generated by Rails crash after a few page loads (not always the same number).
Did you have any luck tracking down the issue? I've asked around in a number of places and come up empty-handed every time.

OSX Server Website DNS problems

I wanted to have a server so I decided to get the mac mini server. We want to set up a small website with simple web services running on python and ruby.
Now I'm trying to set it up to have a website connected to our domain (olm.io), but the domain name doesn't forward to the mac mini server.
I believe the server is set up correctly. The router is set up to port forward incoming connections on port 80 to the server. To test that, connections to the ip 190.160.227.68 retrieves the server and shows up the test website.
I entered our ISP dns servers and also set up a dns server on the osx server.
From outside this shows from outside:

Thanks for the help

You will have two sets of DNS servers, your public DNS and the DNS running on your local network. If your external DNS is getting to your servers, then that's probably working. If you are getting the public IP address from your local network, then your gateway-router needs to "reflect" that address, or you'll need to configure local DNS services (OS X Server needs that in any case) to provide the local IP address for the public DNS name.
Put another way, read the article cited earlier and make sure your local DNS is correct. You can test for most of the common network and DNS configuration errors with the following harmless, diagnostic Terminal.app command:
sudo changeip -checkhostname
...and this will tell you about the configuration, and whether no changes are required, or about the various errors that might be detected.
You can see what IP address you're getting with the following Terminal.app command:
dig +short oc.example.com
...or whatever DNS host name you're using. You'll get either the public IP address (which if you use on the local network, your gateway-router needs to be able to detect that and run the connections back into your network) or your internal local network address.
Your local network clients will want to reference your local DNS server.
Do read the article cited earlier, too.
