omero web start but

[phm]

Hi,
I have Omero running on CentOS 6.5, and omero web using Nginx fastcgi-tcp. And when I trie to connect to the web server (https://localhost/omero/) I get this screen :


Go back to: Webadmin, Webclient or Logout
Page not found. (404)

The requested object or URL was not found on this server. The link you followed is either outdated, inaccurate, or the server has been instructed not to let you have it.

Hi,

Have you created an https config section for nginx? Does it work if you try http://localhost/omero/, without the 's'?

Thanks,

Kenny

Could you try disabling the https redirect and see if it works? If not is there anything in your nginx logs (/var/log/nginx)? What was the exact command you used to generate your omero-web.conf file?

Thanks

Hi Simon,
If I comment the https redirection the http connexion works. Thanks
The command to generate the omero-web.conf is (as in the documentation) :
bin/omero web config nginx --system > omero-web.conf

Thanks

I've just taken a closer look at your omero-web.conf, nginx is only listening on port 80. Does https work for you if you configure nginx to listen on https port 443 (either in addition to or instead of http port 80)?

Code: Select all

    listen              443 ssl;

Hi Simon,

If I enable only https I could'nt connect to the server either with 80 and 443. for https I get ssl_error_rx_record_too_long

Thanks

Hi,

I'd recommend removing any customisation you've made to the central system nginx configuration file /etc/nginx/nginx.conf, since you have the line "include /etc/nginx/conf.d/*.conf;" - meaning you can leave this file at the defaults, and place OMERO's nginx config in /etc/nginx/conf.d/

e.g.

Code: Select all

bin/omero web config nginx --system >> /etc/nginx/conf.d/omero.conf

Hopefully that will get us to a working state.

Then introduce SSL once you have the working OMERO.web.

Best,

Kenny

Hi Kenny,

I did all these things and now nothing works. No http or https connexions, however http://localhost works I get the nginx page

and omero.conf after omero web nginx --system >> /etc/conf.d/omero.conf

Worked through issues with Philippe:

Summary:

Reinstalled Nginx
Moved /etc/nginx/conf.d/default.conf to default.conf.orig
Asked OMERO to create an nginx config, and placed in a separate file in the nginx config dir

Code: Select all

bin/omero web config nginx --system >> /etc/nginx/conf.d/omero.conf

Edited omero.conf from listening on port :8080 to port :80
Restarted nginx

Code: Select all

service nginx restart

OMERO.web interface was now working at http://localhost

All the best,

Kenny
