Bad Gateway

[phm]

I had another thoguht, If you managed to start webserver I think your issues with nginx has nothing to to with OMERO at all. Permission denied must come from some changes in nginx configurations when you installed php-fpm. I would google for that

Ola

You'r right Ola, I did google about php-fpm and nginx, however all proposed solutions didn't change my problem. And I have the hrm conf using fastcgi_pass on 127.0.0.1:9000 which works ?????

Hi Philippe

I'm afraid none of us have any experience with php-fpm. The best I can suggest is to go back to a completely clean OMERO/Nginx install: uninstall Nginx and any related packages, remove all Nginx configuration files (so there should be nothing under /etc/nginx/), then re-install Nginx and regenerate your OMERO.web configuration file.

If OMERO.web works then create a backup and attempt to get your other web services (hrm, php-fpm) working. If you can't then perhaps ask on the PHP-FPM mailing list?

Best wishes

Hi Simon,

Finally I removed nginx and install apache on the server. But now I have Page not found when I try to connect to the omero page, and I have the following error in ssl_error_log :
[Mon Dec 15 16:28:40 2014] [error] [client 192.168.188.18] File does not exist: /opt/OMERO.server/var/omero.fcgi

Here my http conf files

Hi Philippe

Could you try the following:

• comment out all lines in fastcgi.conf beginning with 'FastCgi' (unfortunately they conflict with one of the settings in omero.conf, https://www.openmicroscopy.org/site/sup ... figuration)
• Check that /opt/OMERO.server/var/ and all parent directories are world-readable/executable

Hello,
I have the same problem ... almost.

I have pure installation according the "OMERO.server Linux walkthrough"
CentOS 6.6., Omero 5.0.6, NGINX, and
If I run the nginx by command:

Code: Select all

service nginx start

than I get the error 502 Bad Gateway.

If I run the nginx just as

Code: Select all

nginx

, than it is working.

I thing that it is a permission problem, but I am not able to find it. (I am using the default fastcgi-tcp configuration)

Could you help me?

Hi,

To be able to identify what is exactly the problem, could you:
- send your omero nginx conf,
- send what is in the nginx logfile when you access the URL
- send output of your bin/omero config get

Ola

[xkunes]

Yes I can,
- just the standard installation and nginx is trying to open maintenance.html (but it should not to do that.)
(IPs, names, pass was manually changed.)

Could you double check the permissions on your directories:

ls -ld /home/omero /home/omero/OMERO.server
