Ruby Forum Typo > Typo on mongrel + apache + ubuntu

I have typo running on mongrel proxied thru apache2.  But I have two
problems:
* If a page request comes in while mongrel/typo is down I get an error 
but
when typo comes back up I see it on the port mongrel uses but
apachecontinues to give the error.  I have to restart apache to get 
things
back in sync.  Why?
* What form should my sysv init.d scripts take?  I created the one below 
to
get around my apache restart problem but I see other talk about starting
mongrel instead of typo on reboot.  Which is right?  Can someone point 
me to
a good init.d script that can be used for typo?

#!/bin/bash
# Starts the ruby mongrel server that runs the occamsmachete blog
#

case "$1" in
start)  cd /home/pat/blog
        typo start .
    /etc/init.d/apache2 restart
        ;;
stop)   cd /home/pat/blog
        typo stop .
        ;;
restart)  cd /home/pat/blog
        typo restart .
    /etc/init.d/apache2 restart
        ;;
sweep_cache)  cd /home/pat/blog
        typo sweep_cache .
        ;;
*)  log_action_msg "Usage: /etc/init.d/typo
{start|stop|restart|sweep_cache}"
        exit 2
        ;;
esac
exit 0


I guess this is a mongrel question but thought I¹d try first here in 
case
another typo user has run into this.

Pat,

Unfortunately that is an Apache thing, what it does is determine that
the service it is connecting to as a proxy is down, and it remembers
that it is down.

You would see in the apache error_log (for example)

[Sat Feb 16 11:55:38 2008] [error] (111)Connection refused: proxy:
HTTP: attempt to connect to 127.0.0.1:4485 (xxx.xxxxx.xxx) fad
[Sat Feb 16 11:55:38 2008] [error] ap_proxy_connect_backend disabling
worker for (xxx.xxxxx.xxx)
[Sat Feb 16 11:55:38 2008] [error] proxy: HTTP: disabled connection
for (xxx.xxxxx.xxx)

Sometimes, a hard refresh after starting/stopping typo will resolve it
without restarting apache.  However that is really a limitation of
apache and has nothing to do with mongrel or typo. :(

As far as your init script, it looks fine... you might have a case
where when you stop apache it doesn't kill all of it's children and
the restart fails... not very likely since it's a restart but I've
seen it happen.

BTW, I just did that, it disabled it, re-started typo and it started
working again without restarting apache... running Apache 2.2.8

Hope that helps.

Hmm, I've had typo not start on me on more than one occasion and my
apache hasn't done this.  I wonder what's different about my config.

I'm using:

         RewriteEngine On
         RewriteRule /(.*) http://localhost:8080/$1 [P,L]
         ProxyPassReverse / http://localhost:8080/

I¹m using the virtual host def that came with the most recent typo shown
below.  Do you have sysv init.d scripts to start typo?

<VirtualHost *>
  ServerName blog.occamsmachete.com
  ServerAlias www.blog.occamsmachete.com

  # Change this to your email address
  ServerAdmin pat@occamsmachete.com

  # Change these to be valid paths for your host.  The DocumentRoot path
  # isn't very important because we don't actually use it for anything.
  # For security's sake, it's best that it points to an empty directory,
  # but that's not critical.
  DocumentRoot /var/www/blog
  ErrorLog /var/log/apache2/blog_error.log
  CustomLog /var/log/apache2/blog_access.log combined

  ServerSignature On

  # This is the important part--it sets up proxying.
  ProxyRequests Off
  <Proxy *>
    Order deny,allow
    Allow from all
  </Proxy>

  ProxyPass / http://localhost:4155/
  ProxyPassReverse / http://localhost:4155/
  ProxyPreserveHost On
</VirtualHost>

Oops, sorry, missed your reply.

No, I have to admit to having some rc.local lines. :P
