Starting Rails apps on server's reboot

Rails
1

Hello list,

I’ve got a server with several Rails application running under mongrel.
It
works fine, but the problem is when I reboot it. Having to go to each
app’s
dir and restart mongrel is a pain, so I would like to know if there’s
already something (maybe a rake task or bash script) that solves this
problem? If not, what would be the recommended way? A bash script?

Thanks in advance.

Use whatever mechanism your OS uses for other services, likely an rc

Pat, thanks for the reply.

So basically I should add to the script a line to start mongrel for each
Rails app I have on the server?

I use @reboot in cron:

@reboot cd /www/eq2guild/guildcorner/current && ./script/spin
@reboot cd /www/blog/flame-blog/current && ./script/spin
…

That starts the tasks as a user I choose (in my case, the user is
named ‘webtoys’) and since cron starts very late in the OS boot
process, things will generally be well up and running before my
application starts.

Note that if you put them in an rc script, they might run as root
unless you specifically ask them them not to. And then what happens
if you mess up that file? Will the system still boot?

Running things in a crontab also has the advantage that anyone who can
run the crontab command can set it up – no special root privs needed.

On Linux systems, aren’t daemon tools or runit a more attractive
option? These have the added benefit of restarting Mongrel whenever
it stops, regardless of the reason. I used to have this working using
mongrel_cluster, but I haven’t had it working right since switching to
Capistrano 2.1. Cap2.1 doesn’t support the mongrel_cluster gem, and I
haven’t fully figured out everything necessary to make it work again.

I also have a backgroundrb task to restart.

Anyone have the magic for runit?

Hi Marcelo

In the Win2003 server environment, just set each mongrel service to
start automatically.
