Redmine

Hello,
I am creating high availability clustering so that I create 3 server (server1, server2,server3) using pacemaker.
I want to add many resources into this servers for example apache redmine etc..
now I have problem running redmine.
I created redmine platform each server. And setup passenger.conf and 000-default.conf

/etc/apache2/mods-available/passenger.conf

PassengerDefaultUser www-data
PassengerUserSwitching on
PassengerUser redmine
PassengerGroup redmine

/etc/apache2/sites-available/000-default.conf

<Directory /var/www/html/redmine>
RailsBaseURI /redmine
PassengerResolveSymlinksInDocumentRoot on
</Directory>

I do it in each and every server.
server2 get actual output (redmine homepage)
on server1 i got message "*We're sorry, but something went wrong.*
We've been notified about this issue and we'll take a look at it shortly."
on server3 i got Index of /redmine

why I got different output for different server? what is the reason for this kind of output?
