We have been searching for a Rails deployment architecture which works for us for some time. We''ve recently moved from Apache 1.3 + FastCGI to Apache 2.2 + mod_proxy_balancer + mongrel_cluster, and it''s a significant improvement. But it still exhibits serious performance problems. We have the beginnings of a fix that we would like to share. To illustrate the problem, imagine a

I have an Apache 2.2.3 (mod_proxy_balancer) frontend server that does not have mongrel installed. It does proxy requests to several other mongrel-only servers (each running 2 mongrel processes). Each mongrel node has the same rails code-base and it''s working perfectly. However, my question is when I add an upload file form... where is it going to physically put that file? I mean since

Hey All, I just wanted to get other peoples take on problems when running merb in production? Just as Rails used to do, the mongrels tend to get heavy/unresponsive over time so need a good kicking by a watcher daemon like god or monit. However, I have had serious problems getting God to restart the process, as the "merb -k <port>" command doesnt appear to work reliably

Hello Mongrels, Building on the last messages about Fastthread, can we get a detailed survey of the different ways people are deploying their applications? It will help with near-future Mongrel development. Please include the following things: * Framework, if any (Camping, Merb, Rails, Nitro, Ramaze, IOWA, Rack...) * Mongrel version * Mongrel handlers used (rails, dirhandler, camping,

Hello! What is the simplest way to make merb respond to the client sending Accept-Encoding: gzip? Just checking if it exists, otherwise I''ll implement it myself. Regards, Magnus

Hi, I''m having a problem where connections started through BackgrounDRb::MiddleManDRbObject.init are not stopped, resulting in an ever growing established connections between my Mongrels and remote backgroundrbs I added DRb.stop_service to my code executed after requests that init MiddleManDRbObjects but that does not help. Any ideas? Thanks, Robert Bjarnason

hi, i am trying to grasp some concepts about mongrel, rails, and backgroundrb on how they all work in terms of threads and such. is there a book about distributed ruby and processes? i havent seen any on amazon yet... from my blog reading, i have some questions.... rails can handle 1 request at a time and can buffer to a certain extent? when mongrel instances are created, a copy of the rails

Hey All, I am looking for an example of the proper config settings for background rb to run my rails app and my backgroundrb instance on separate machines (or more precisely, to have a rails cluster with one backgroundrb machine). Does anyone have such examples? Thanks! -Noah -------------- next part -------------- An HTML attachment was scrubbed... URL:

I''m following merb trunk. This morning I updated my gems, sync''d merb source and installed the merb gem from source. I don''t know if I did something wrong, or if a new gem messed things up, or if there was a merb change which broke something. Now I get this error: Request: REQUEST_URI: / (2007-11-05 20:27:04) Params: {"action"=>"index",

Has anyone had troubles from Mongrel > 1.0.1? Just curious, because the last time I tried to run Merb it gave me some Mongrel error about the wrong number of arguments, or something like that. I can post the exact message tonight when I get home. -- Cheers, Kevin Williams http://kevwil.com/ http://www.almostserio.us/ http://kevwil.jaiku.com/

Hello, maybe someone can help with backgroundrb. I''ve written an application, which makes use of backgroundrb. Everything works fine on my development machine, but it crashes on my production server. Something seems to be wrong with backgroundrb, but I don''t know the cause. All I get is the error message attached below, which is extracted from the production.log. I

Hi, first off thanks Ezra for Merb - it''s certainly interesting and I''m keen to have a play. However, I''m having difficulties in getting started. I''ve followed the docs for setting up mrblog and everything seems to be installed correctly, and merb appears to start fine: $ merb you must install the markaby gem to use .mab templates you must install the

Hi all, We use mongrel behind apache (using mod_proxy_balancer) to run an internal app for our business. Lately we''ve been seeing frequent errors from some of our mongrel processes. [Sun Dec 16 08:48:47 2007] [error] [client <CLIENT1>] (70007)The timeout specified has expired: proxy: error reading status line from remote server 127.0.0.1, referer:

I''m having trouble getting backgroundrb up and running in a production environment. Here''s my backgroundrb.yml: --- port: "22222" timer_sleep: 60 load_rails: true environment: production host: XXX.XX.XXX.50 database_yml: config/database.yml acl: deny: all allow: localhost 127.0.0.1 XXX.XX.XXX.51 order: deny,allow I start BackgroundRB from XXX.XX.XXX.50 with

Hi, I''ve been looking for a light weight alternative to rails for a few small projects, and just came across merb, which looks perfect. The only issue is that merb seems to be tied to mongrel, and I have to deploy to our internal infrastructure which uses FastCGI. How difficult would it be for me to modify merb to support a fcgi interface (actually a rack interface - rack is

Hi, Can somebody point me in the right direction about what approach would be best to load-balance between two or more physical servers running backgroundrb while using BackgrounDRb::Worker::RailsBase with mongrel? Thanks, Robert Bjarnason

Hi , If you are following commits, I have pushed following changes: 1. Now, you can specify :environment option in config file to load production environment and stuff. 2. Exeptions that were exposed to the user has been changed to BdrbConnError if rails is not able to connect to bdrb server. 3. loading mechanism has been changed, so remove backgroundrb script from your backgroundrb directory

I have an archiving application that handles large file uploads. I already use backgroundrb to run a behind the scenes bulk import of records. All good. Thank you Ezra. Now I would like to add long running file uploads to the things that backgroundrb does for me. That''s right that ole chestnut. I''ve seen a lot of mention of this practice around the web, but have yet

I have a worker as follows: class SampleWorker < BackgrounDRb::MetaWorker set_worker_name :sample_worker def create(args = nil) # this method is called, when worker is loaded for the first time end def my_method # Deliver test e-mail message Notifications.deliver_message(1, "DM") end end I have a rails controller that calls the following code: worker =

hi all, I want to move some routing tasks out of the router and into the controller. The goal is to make Merb feel less like mod_rewrite and give the user more control at the controller. The new Router is simple: it takes the path_info (not the whole request) then outputs a controller class and some parameters from the path matching. The rest of the routing would be done at the controller level.
