    I successfully implemented ruby on rails with the tutorial from howtoforge for debian, running on a debian 3.1 machine.
    users also have chrooted ssh access.

    one problem I have, is that a client is constantly complaining, that as he tells me his site is running in production mode, and to see changes he made, he asks me to do a killall dispatch.fcgi after each of his changes so they reflect in the online version.
    this seems dubious to me but he explained, he needs a killall after every change because in production mode changes are not reflected without reload...

    Now I am wondering how to fix his problem without compromising security... all dispatch.fcgi processes are running as the www-data user

    What is the way to go? Could somehow tell me how they solved this? did anyone get the suexec wrapper to work with ruby on rails?

    I also noticed that I am still running fastcgi not fcgid also I have both modules enabled inside apache2 but if I disable fastcgi the site stops working, so I need some help with that too :-(

    falko or tim are you interested in giving paid support?

    anyone else got some tips and tricks on this subject?

    regarding the use of mod_fcgid:

    I already did these steps:

    We will also need to modify the .htaccess file in the same directory. You'll have to search for the line:
    RewriteRule ^(.*)$ dispatch.cgi [QSA,L]

    replacing it with:
    RewriteRule ^(.*)$ dispatch.fcgi [QSA,L]

    If you use mod-fcgid instead of mod-fastcgi, you will have to change the following line too, in .htaccess:
    AddHandler fastcgi-script .fcgi
    replacing it with:
    AddHandler fcgid-script .fcgi

    I also found this on their original homepage:

    the problem is I have done all that is suggested to get mod_fcgid running, but nevertheless when I a2endismod fastcgi and force-reload apache2 the site stops working...

    I am especially unsure about this line, as to where to add it:
    FCGIWrapper '/usr/bin/ruby /var/www/web2/web/dispatch.fcgi' .fcgi

    with fastcgi I used this line inside /etc/apache2/mods-enabled/fastcgi.conf:
    FastCgiServer /var/www/web2/web/dispatch.fcgi -idle-timeout 120 -processes 2

    I read another tutorial for having apache2 serve static content + php and proxy ror apps to a mongrel server.

    but this would mean, I set up the proxying for the ROR sites, and the users have to manually start their own mongrel server? this smells like trouble, too much control and responsibility on the users side...

    open for other suggestions...

    ok, I tried to give those users that use ruby the possibility to killall dispatch.fcgi which means the ruby process will be restarted. I tried to do it with sudoers but it does not work out.

    web2_test ALL=NOPASSWD: /usr/bin/killall dispatch.fcgi

    but when I do a su web2_test and do a killall dispatch.fcgi I get this:

    any other ideas how to solve this?

    hi Tenaka,

    first sorry for my english,

    I saw that you tried to give the user the posibility to killall fcgi instances, now I want to make the same, did you can resolved this issue???

    I think the problem is that the fcgi instance is started by www-data user, then I want to find the way to start the process by each one of the web users..
