similar to: mongrel cluster and rails cache.

Greetings, I posted this not on the Rails mailing list and didn''t get a definitive response so I thought I''d post it here, since I figure lots of you are using mongrel with Rails apps. Any suggestions would be greatly appreciated. I''ve been using file-based fragment caching and DB-based session caching quite extensively. I decided to try out memcached for both to

Hi all, I am out of my head here... I have a 3 node cluster with 10 mongrels running on each. When I deploy, I break all the mongrels every time. I have tried just about everything. I can restart my mongrels without a hitch manually, it''s only when I use cap deploy. Maybe I am missing something here... so if I can get some help it would be appreciated. The errors are the typical mongrel

Hi, I am deploying a Rails website using Capistrano to a VPS running the site through Apache and Mongrel. ''cap deploy'' works fine, and mongrels are restarted. When I execute ''cap deploy:rollback'', however, my script fails to restart the mongrels giving this error: !!! PID file tmp/pids/mongrel.5000.pid already exists. Mongrel could be running already.

While I could figure this out, I''m asking here first to see if anyone has already dealt with/created this. I''m running a mongrel cluster, running 4 mongrels on ports 8001-4. I''m using capistrano to deploy. And I''d like to use monit to check to make sure everything is running nice. I''d like to have monit restart only single mongrels if they fail, and

I just created a test rails app, and am having very wierd issues with mongrel cluster. Here''s what I''m doing: rails test sudo chown -R mongrel:mongrel test cd test sudo mongrel_rails \ cluster::configure -e production \ -p 8000 -N 3 -a 127.0.0.1 --user mongrel \ --group mongrel It correctly writes the mongrel_cluster.yml file to the config directory. Now,

I want to restart my Mongrels from crontab periodically to free up memory. I tried this: [admin at mudcrapce ~]$ mongrel_rails cluster::restart -C /var/www/apps/mudcrapce/current/config/mongrel_cluster.yml Restarting 5 Mongrel servers... mongrel_rails restart -P log/mongrel.3040.pid !!! PID file log/mongrel.3040.pid does not exist. Not running? mongrel::restart reported an error. Use

The company I work for is launching a new web site tomorrow. News of our launch will be published in major publications throughout the week so I want to make sure we are prepared for the load. Production Environment: HP Proliant server w/ 8GB RAM and dual AMD64 Opterons Memcache is used as the session and fragment store (512MB for it) MySQL is running on a seperate server in the same rack We use

Let me give you the background. I am using rxml for a lot of my views for a rails project. I also noticed that there is a lot of the XML being dynamically generated on data that doesn''t change that often. I worked on trying to cache the xml fragment that I needed but came to the quick realization that cache only handle ERB/RHTML files. Needless to say, I have spent some time creating an

Hi -- I have been reading documentation and googling around to find the correct way to do this but I have found many ways that seem to not work, or the documentation makes no reference to. I am using mongrel cluster with 10 mongrels for each server. Recently I installed monit but which lead me to find the correct way to start/stop mongrel instances one pid at a time. I am assuming one pid at a

Hi All, Machine A: has Apache 2.2 doing load balancing, also has DB and 8 mongrel processes I''m using mongrel_cluster . Now, I want to run Mongrels on Machine''s B and C (ie Cluster 3 Mongrels in three different machines). Is this possible? If possible then, please describe me the steps required (I''m using windows machines, and already losdt one week :-( ) Best

Hi All, I am new to the mongrel mailing list and I have a question (and I didn''t find any answer in the archives). I have successfully installed the apache2.2 proxy balancer with mongrel cluster and that works just fine. For a single rails app I have started 2 mongrels which consume about 100M (ps says 5.0% for each and I have 1G RAM). It seems a bit much but OK. However that would

Hi all, I just wanted to share a project I''ve been working on now for a few months. It''s still far from complete, but has already been very useful for me and my coworkers. I''m calling it mongrel-esi. ESI stands for Edge Side Include. The specs live here, http://www.w3.org/TR/esi-lang. I currently only have support for <esi:include, <esi:try,

Hi all: Here''s a pre-release for mongrel_cluster to support current Mongrel 0.3.13.4 pre-release. Changes: - ''mongrel_rails cluster::restart'' now calls ''mongrel_rails stop'' and ''mongrel_rails start''. ''cluster::restart'' now accepts the ''force'' argument instead of ''soft''. -

Hi, I''ve configured a rails application on my VPS to run on two mongrels. When I run curl on localhost, the starting page comes up fine. That is, mongrel is serving the app perfectly. The problem arises when trying to access the app on my ip through apache. I get a 403 error. Just to test things out, I''ve set generous permissions on the entire rails directory structure

Hi all, I''ve been having problems with the apache 2.2-mod_proxy_balancer- mongrel setup. My setup is: CentOS 4.3 apache 2.2.3 (compiled from source) with mod_proxy_balancer mysql 4.1 ruby 1.8.4 mongrel 0.3.14 (I know I need to update but I think this problem is independent of the mongrel version) mongrel_cluster 0.2.0 rails_machine 0.1.1 I have apache setup as per Coda''s

Hi, I''ve a few problems with my rails app at the minute, causing mongrels in a cluster to die, while I debug I''ve setup monit to keep the site running. Problem is, whenever monit starts one of my mongrels via mongrel_rails cluster::start --only 8000 --clean -C /url/to/yml/file I get the following in my log/mongrel.log: ** Mongrel available at 127.0.0.1:8000 ** Writing PID file

According to the mongrel_cluster.yml file you provided, you''re starting only 14 mongrels, but in your proxy balancer config you have 30 mongrels listed on ports 21000 - 21029. In this scenario, if apache tries to proxy to any ports higher than 21014 then you''ll get a proxy error as a mongrel doesn''t exist on that port. Or am I missing something? -----Original

Hello, I''m a noobie to Rails and even more to mongrel. I have an issue with one server that I''ve installed mongrel. Its a Fedora Core 5 box, and it is having problems loading the Oracle OCI8 libraries. However, this only occurs when I use mongrel_cluster, or mongrel with out the - d switch. I have no problem using the library from the commandline and with Webrick or

I''m running two sets of mongrels using mongrel 1.1.4, one for production one for staging. When executing ''ps'' from a linux shell, the production mongrels report as expected, however the staging processes are listed as [ruby 18]. The result seems to be that mongrel_rails cannot stop the staging processes because it doesn''t recognize [ruby18] as a mongrel

I''ve done a clean install of Ubuntu 7.04 server in 2 different machines and everytime I reboot the machine or manually run /etc/ init.d/mongrel_cluster restart/start the mongrels won''t start correctly. I have to manually start them by using mongrel_rails cluster::start from each app folder. I''ve been searching around and it looks like mongrel has some problems
