apache configuration for SequenceServer, sinatra error

sequenceserver
#1

Hey

I’ve successfully installed SequenceServer and got it working under the default webserver and port 4567. But when I tried to get it run with the apache webserver, I encountered the following problem: After following the instructions (SequenceServer on Apache or Nginx with Phusion Passenger), I modified my apache config file httpd.conf to

<VirtualHost *:80>
ServerName www.diamond.tuebingen.mpg.de

!!! Be sure to point DocumentRoot to ‘public’!

DocumentRoot /var/lib/gems/1.8/gems/sequenceserver-0.8.7/public/
<Directory /var/www/blast/ >

This relaxes Apache security settings.

AllowOverride all

MultiViews must be turned off.

Options -MultiViews

included the path to my SequenceServer config file to the config.ru file
…
SequenceServer::App.config_file = ‘/home/roedel/.sequenceserver.conf’
SequenceServer::App.init
run SequenceServer::App

and restarted apache.
When I now access www.diamond.tuebingen.mpg.de/blast/ from my web browser, I get the message

Oops! Something went wonky!

Apologies, there was an error with your request: Sinatra::NotFound

I would greatly appreciate any help.

Thanks a lot

Christian

PS. Here is the error log of the apache webserver:

I tried a little bit more and used the information on http://collab.stat.ucla.edu/users/jose/weblog/9e335/

Essentially, I added a symbolic link to SequenceServer in my DocumentRoot folder /var/www

sudo ln -s /var/lib/gems/1.8/gems/sequenceserver-0.8.7/public/ blast

and modified the default file in the /etc/apache2/sites-available folder

DocumentRoot /var/www

Options FollowSymLinks
AllowOverride None

<Directory /var/www/>
Options Indexes FollowSymLinks MultiViews
AllowOverride None
Order allow,deny
allow from all

RailsBaseURI /blast
RailsEnv development

and restarted apache

sudo /etc/init.d/apache2 restart

Hi Christian,

I’m glad your problem could be solved, and thank you for contributing your solution back to the mailing list.

I followed these tips but couldn’t get to the ‘blast’ page, the httpd error log says ‘…/…/gems/sequenceserver-0.8.7/public/blast’ does not exist. I’m sure this is a simple symlink problem: why is it keep pointing to /public/blast/ instead of /public?

Thanks!

Hi Ke,

Would you mind sharing your apache config please? Also, first thought is that it might be due to a relative rather than absolute symlink that Christian created - how did you make the symlink?

Thanks,
ben

Hi, Ben,

Thanks for the response! I’ve read a bit more on passenger and apache and have found a solution, mainly from here:

https://www.phusionpassenger.com/documentation/Users guide Apache.html

In the end, I didn’t change the root document, nor did I use any symlinks. I added this block in my httpd configuration:

<VirtualHost *:80>
ServerName *****

!!! Be sure to point DocumentRoot to ‘public’!

DocumentRoot /usr/local/lib/ruby/gems/1.9.1/gems/sequenceserver-0.8.7/public/
<Directory /usr/local/lib/ruby/gems/1.9.1/gems/sequenceserver-0.8.7/public>

This relaxes Apache security settings.

AllowOverride all

MultiViews must be turned off.

Options -MultiViews

create an alias to the application

Alias /blast /usr/local/lib/ruby/gems/1.9.1/gems/sequenceserver-0.8.7/public/

setup the URI

<Location /blast>
PassengerBaseURI /blast
PassengerAppRoot /usr/local/lib/ruby/gems/1.9.1/gems/sequenceserver-0.8.7/

point to the application location

Allow from all Options -MultiViews

Looks like creating the alias ‘blast’ correctly finds the place ‘/var/www/html/blast’. I only used this for CentOS 5.9, so I’m not sure whether it holds for Ubuntu/Debian systems.

Thanks!

Ke

Well, that is pleasing. Thanks for contributing your solution back to the mailing list.
