Help with Apache config

Rails
1

I have been attempting for days to configure Apache for Rails. I have
read forums, followed How-To’s all in vain. I am hoping someone can help
me out. I am getting the Rails Welcome screen, but when trying to go to
any other url, I get the 500.html message. Take a look for yourself at
http://66.139.78.237 and click on “about your application’s
environment”.

Below is my VirtualHost directive in httpd.conf. I can provide more
info if necessary.

<VirtualHost *:80>

SetEnv RAILS_ENV production
DocumentRoot /usr/local/apache/htdocs/test/public/
ErrorLog /usr/local/apache/logs/apache.log
ServerName 66.139.78.237
LogLevel emerg

<Directory /usr/local/apache/htdocs/test/public/>
Options ExecCGI FollowSymLinks
AddHandler cgi-script .cgi
AllowOverride all
Order allow,deny
Allow from all

Now you need to look in the rails error log.
It’ll be in

RAILS_ROOT/logs/production.log

If that’s blank, apache probably has trouble running cgis, so look in

/usr/local/apache/logs/apache.log

How is your configuration of mod_fcgi ??

You should have something like

FastCgiIpcDir /tmp/fcgi_ipc
FastCgiServer /usr/local/www/my_ror_app/public/dispatch.fcgi
-initial-env RAILS_ENV=production
-idle-timeout 30

Do you ?

Yes, Here is what I have… It looks a little different than your
example… Maybe I should change it?

FastCgiIpcDir /tmp/fcgi_ipc FastCgiServer fastcgi-script .fcgi -initial-env RAILS_ENV=development \ -idle-timeout 60

I have been using it, however the sessions directory is clear. Is the
“permission denied” referring to the dispatch.fcgi script? Looks like
all should have execute permission there:

-rwxr-xr-x 1 zwilliam apache 473 May 17 07:29 dispatch.cgi
-rwxr-xr-x 1 zwilliam apache 855 May 17 07:29 dispatch.fcgi
-rwxr-xr-x 1 zwilliam apache 473 May 17 07:29 dispatch.rb

That’s not what the error said. Are you sure you’re checking the right
directory? Should be:

/usr/local/apache/htdocs/test/tmp/sessions/

No, it’s not that. You’re not using fastcgi yet.

I have often wondered about this IfModule mod_fastcgi.c setting. Don’t
seem to need it. At least everything runs fine without it. What do I
gain by putting this in?

The IfModule is just a check to be sure that mod_fastcgi is available on
the system…

Sorry… I was unclear… I meant the whole part. including this part of
it.

FastCgiIpcDir /tmp/fcgi_ipc
FastCgiServer /usr/local/www/my_ror_app/public/dispatch.fcgi
-initial-env RAILS_ENV=production
-idle-timeout 30

Is it just to cofigure the enviroment? What if I have multiple rails
apps. Do I simply have multiple FastCgiServer lines?

WebBrick runs as your user, but apache runs as a different user. Make
sure Apache has write access to the sessions/cache/sockets in
yourapp/tmp.
