Omero 5.0.0-beta1 and fastCGI

[bpavie]

Hi everybody,

I finished to install OMERO 5 beta1 following the online tutorial available at https://www.openmicroscopy.org/site/support/omero5/sysadmins/unix/server-install-linux.html on Ubuntu 12.04 LTS and everything went fine.
However, when I tried to not use the web development and integrate the omero web interface into Apache, things didn't work:
I followed the tutorial available here:
http://www.openmicroscopy.org/site/supp ... l-web.html

But my main problem is that after configuring omero we to use fastcgi and started the web server:

Code: Select all

omero config set omero.web.application_server "fastcgi-tcp"
omero web start

I cannot see any omero.fcgi file mention in the /etc/apache2/sites-enabled/99-omero-web.conf generated by running the command

Code: Select all

omero web config apache

Code: Select all

RewriteEngine on
RewriteRule ^/?$ /omero/ [R]

Alias /static /opt/OMERO/OMERO.server/lib/python/omeroweb/static
Alias /omero "/opt/OMERO/OMERO.server/var/omero.fcgi/"

So when I access to mywebserver.com/omero, I got an error message and the following in the apache.log file:

Code: Select all

[Tue Jan 14 15:35:54 2014] [notice] FastCGI: process manager initialized (pid 5318)

I am probably missing something, but I can't see what.

Any help will be appareciate
Thanks,
Benjamin

Hi Benjamin,

The first thing there is that you have a UNIX socket configuration when you are trying to use TCP.

Code: Select all

omero config set omero.web.application_server "fastcgi-tcp"

FastCGIExternalServer "/opt/OMERO/OMERO.server/var/omero.fcgi" -socket "/opt/OMERO/OMERO.server/var/django_fcgi.sock"


So configuration is definitely mismatched.

I am guessing, it came like this because apache config had been generated before setting "omero.web.application_server" to "fastcgi-tcp". Please either run "omero web config apache" again or just change the following:

Code: Select all

FastCGIExternalServer "/opt/OMERO/OMERO.server/var/omero.fcgi" -host 0.0.0.0:4080

I hope it will help.
