Subject: [Mongrel] mongrel_rails start and restart differences
Message-ID: <7e68c833cde0b111f2b064605da96f25@ruby-forum.com>

Hello everyone.

I've got a rails application that is using 3 mongrels that sit behind
nginx.  I'm  monitoring the mongrels, nginx and mysql with Munin and I'm
restarting the processes when they hit certain levels with God.

Can someone shed some light on this for me.

I'm starting the mongrels off with this command, looping through 3
ports.

mongrel_rails start -d -e production -a 127.0.0.1 -c
/var/www/rails/daughter/current -p #{port} -P
/var/www/conf/log/mongrel.#{port}.pid -l
/var/www/conf/log/mongrel.#{port}.log.

If my mongrels start chewing up too much memory I restart them like so

mongrel_rails restart -P /var/www/conf/log/mongrel.#{port}.pid

All works well.  The problem is that munin does not record the mongrel
after it's been restarting as the restarted mongrel runs underneath a
ruby process as opposed to a mongrel_rail process.

Here's what ps aux | grep mongrel_rails outputs after one mongrel has
restarted.

/USR/BIN/RUBY1.8 /USR/BIN/MONGREL_RAILS START -D -E PRODUCTION -A
127.0.0.1 -C /VAR/WWW/RAILS/DAUGHTER/CURRENT -P 5001 -P
/VAR/WWW/CONF/LOG/MONGREL.5001.PID -L /VAR/WWW/CONF/LOG/MONGREL.5001.LOG

RUBY /USR/LIB/RUBY/GEMS/1.8/GEMS/MONGREL-1.1.5/BIN/MONGREL_RAILS START
-D -E PRODUCTION -A 127.0.0.1 -C /VAR/WWW/RAILS/DAUGHTER/CURRENT -P 5000
-P /VAR/WWW/CONF/LOG/MONGREL.5000.PID -L
/VAR/WWW/CONF/LOG/MONGREL.5000.LOG

I've capitalised them all so don't worry about the switches, any ideas
why mongrel_rails start does this

/USR/BIN/RUBY1.8 /USR/BIN/MONGREL_RAILS START

but mongrel_rails restart does this
RUBY /USR/LIB/RUBY/GEMS/1.8/GEMS/MONGREL-1.1.5/BIN/MONGREL_RAILS START

Any help would be greatly appreciated.

I have you tried mongrel_cluster_restart ?

You can define a config file which says how many servers to startup,
and what port # to start at (ie: 9000).
You can also do a --clean to remove old pid files.

Subject: [Mongrel] mongrel_cluster : up to 500 MiB memory
Message-ID: <d2a1bbf1adae65970a464885babc5d85@ruby-forum.com>

Hi everyone,

I've got some trouble with my RoR application running with apache
(2.2.9) and mongrel (1.1.5).

The site i manage has about 20'000 visits a day, and we run 14 mongrel
instances switched with mongrel_cluster (1.0.5). The fact is, sometime,
half of my mongrel instances are raising something like 500MiB memory
and don't seem to work anymore.

The server itself has 8 CPU's and 8Go of RAM.

I read different how-to's about mongrel and mongrel_rails but most of
them are just talking about how to start with mongrel.

I would like to know if there is a way to monitor mongrel instance
and/or how to improve my configuration?

If anyone has a suggestion, it'll be very helpfull.

You didn't specify exactly what you want to monitor but a lot of
people use Monit to monitor their mongrel clusters: 
	http://mmonit.com/monit/

I have also heard people talk about using 'god'

Subject: [Mongrel] Disabling static file lookups?
Message-ID: <749ead610812111805y635c08c5yfd3ae1cb4d881ba3@mail.gmail.com>

In looking at a running mongrel process in strace and at the code
itself Mongrel will always look for a file under "public" (with and
without a .html extension). When those filesystem lookups fail, it
then passes the request to Rails.

So my question is, would you get more performance by disabling this
lookup and just handing it off to Rails from the get go?

I understand that in development, the current behavior is desired as
Mongrel is acting as the primary HTTP server. But in production, with
a HTTP server like Apache or nginx in front and configured to serve
static files, then it might make sense to not have Mongrel concern
itself with looking for static files.

Maybe the OS caches those filesystem calls (stat cache?) and this
would be a crazy premature optimization.

Thoughts?

	You should be able to alter the railshandler to not do these lookups  
when a config option is set. Merb uses rack middleware to do the  
static pages and that can be easily turned off in production. I  
believe latest rails does this as well and maybe you can disable these  
checks with rack in rails as well?

Ezra- thanks for your feedback.

My greater question is: is it worth it, in the long run? Or is it too
negligible?

	Hmm i bet it is probably worth it but only if you are trying to  
squeeze every last drop of perf out of your setup. A fast local  
filesystem does stats fairly quick and I doubt you will be bale to  
tell the difference.

	But if you have overtaxed disks or are using NFS or a shared  
filesystem of sorts then every littel bit helps to keep from touching  
the filesystem.

	So its probably worth it eventually when you get big but probably is  
not worth it until you actually know it is a problem.

Hello,

I am having to restart my mongrel_cluster instances every morning because they are hung.
Has anyone else had this problem.

I am running Red-Hat 5.0 and Mongrel_cluster (1.0.5) and Apache (2.2.3).

I have a strace of the mongrel_cluster when it is hung.

I don't have mongrels hanging, but I _do_ have mongrels that cease to 
exist without leaving anything in the logs at all. Very odd.

I did get past this but now the "service mongrel_cluster" fails with the 
following; (i've added the env command to the script)
service mongrel_cluster start

Let me be clear on this... did you add /usr/local/bin to the path in such a
way that 'service mongrel_cluster start' showed PATH=/usr/local/bin:..., but
the cluster did still not start?  Or do you mean that you didn't succeed in
adding /usr/local/bin to the path?  Or something else?

Seeing as three months have gone and we're now in a different era, you could
have a go at setting up apache with mod_rails instead.  The time might be
better spent there; I understand that mod_rails (Fusion passenger) is a nice
experience.

Good luck!

Hello,

I am having to restart my mongrel_cluster instances every morning because they are hung.
Has anyone else had this problem.

I am running Red-Hat 5.0 and Mongrel_cluster (1.0.5) and Apache (2.2.3).

I have a strace of the mongrel_cluster when it is hung.

Hello.

I use capistrano with mongrel and apache.

When I cap deploy:start, It launches nothing. So I :
sd-17133:/var/rails/canardps3/current# mongrel_cluster_ctl start
Starting all mongrel_clusters...
/usr/local/bin/mongrel_cluster_ctl:7:in `chdir': No such file or
directory - /etc/mongrel_cluster (Errno::ENOENT)
        from /usr/local/bin/mongrel_cluster_ctl:7:in `run'
        from /usr/local/bin/mongrel_cluster_ctl:55
guess it may be the problem. Any idea on what can I do to fix this ?

clearly you are missing a configuration file on the server. /etc/ 
mongrel_cluster.. you need to create a configuration file to start  
your mongrel cluster. It first looks into your rails config directory  
and then in /etc/mongrel_clusters.

Have you tried passing a configuration file in?

I have my config file for prod, qa, etc. under
./config/{environment}_mongrel.conf

The cluster can be started with -c ./path/to/config/file   (which has
startup directory, ports, etc)...or you can create a directory in
/etc/mongrel_cluster that has symlinks to all your config files for
each environment.

Sylvain, can you post your mongrel_cluster_ctl to the list?  It looks like
your start script is trying to find a file but it's not there.

Ok, I get the config file, but in fact this don't make the cap deploy:start
working.

Some information :

my script/spin :

#!/bin/sh

/var/rails/canardps3/current/script/process/spawner \

mongrel \

--environment=production \

--instances=1 \

--address=127.0.0.1 \

--port=8000



my spawner :

#!/usr/bin/env ruby

require File.dirname(*__FILE__*) + '/../../config/boot'

require 'commands/process/spawner'



I got no error except
C:\railsapp\canardps3>cap deploy:start
  * executing `deploy:start'
  * executing "cd /var/rails/canardps3/current && sudo -p 'sudo password: '
-u s

    command finished

but a ps aux | grep mongrel isn't returning a thing.

Were can I find some clue ?

I did add /usr/local/bin to the path in the mongrel_cluster file and I 
still had issues; these were other ruby issues.
What I ended up doing was creating a custom file to do the start and 
stop. That worked and I did have to add /usr/local/bin to the path.

I've pasted in the file I created; I am sure there are issues with it. 
But it works...

Thanks for your help the path suggestion was key to my getting this to 
work.

Subject: [Mongrel] rails 2.2 upload progress handler
Message-ID: <aebc58490812180114v2ff7c698y373ce44d19375f47@mail.gmail.com>

Hello,

I am trying to change my rails 1.2.6 application to rails 2.2
I have made all the other changes and able to make everything work
except upload progress.
When I try to start the mongrel server using the command

 mongrel_rails start -S config/mongrel.conf

it throws the error

** Rails loaded.
** Loading any Rails specific GemPlugins
** Loading config/mongrel.conf external config script

`run'
	from /usr/lib/ruby/gems/1.8/gems/mongrel-1.1.5/bin/mongrel_rails:281

the

config/mongrel.conf contains

uri "/",
  :handler => plugin("/handlers/upload", :path_info =>
'/upload/create', :memcached => UPLOAD_PROGRESS_CACHE),
  :in_front => true

We are using memcache to store the upload progress info. This works
smoothly in Rails 1.2.6.
What has changed in the new rails version which is causing this error,
how to get it working?

Any help on this issue will be much appreciated.

Thanks in advance.

I realize not many people will benefit from this, but it would be nice
if mongrel_rails, in development mode, output the tail of its log "with"
color output on windows.
Currently it outputs it with the Linux style coloration marking which is
somewhat confusing.
Thanks!

Is not possible.

For that mongrel will require to depend on win32console to capture
ANSI coloring and output colored strings.

ANSI coloring differs from Windows coloring since Windows allow page
locks and memory buffers to be updated. In that front, ANSI is dumb.

If you want color highlight use tail from msys ;-)

Anyway, now I realize it better, mongrel_rails doesn't output with
colors, the one that outputs is Rails to log/development.log.

One thing that could be done is to force a GC every "x" requests--that 
way a GC is for sure run between requests [at least with single threaded 
rails] and that way the stack is most shallow and the GC will not pick 
up ghost references left on the stack.  But hopefully we won't have to 
worry about that soon :)

There are some patches on ruby-core that discuss a sweller GC maybe that 
would help.
