Code: Select all
systemctl start omero-web

Thanks, Simon

Hi,
I did the change in the omero-web.service file except for the line :
Environment="PATH=/home/omero/omerowebvenv/venv/bin:/bin:/usr/bin"
Modified as
Environment="PATH=/home/omero/omerowebvenv/bin:/bin:/usr/bin"
/home/omero/omerowebvenv/venv/bin don't exist !
I restarted the deamon, however the problem is the same :
Code: Select all
root@omero:/home/omero#>systemctl daemon-reload
root@omero:/home/omero#>systemctl enable omero-web.service
root@omero:/home/omero#>systemctl start omero-web.service
Job for omero-web.service failed because the control process exited with error code. See "systemctl status omero-web.service" and "journalctl -xe" for details.

Hi Simon,
I did the modifications in the file omero-web.service except for the path because /home/omero/omerowebvenv/venv/bin should be /home/omero/omerowebvenv/bin
After reloading and restarting the deamon I got the same error :

Could you try one last change for me? Get rid of WEBBINDIR completely and use the full path:
Code: Select all
Environment="PATH=/home/omero/omerowebvenv/bin:/bin:/usr/bin"
ExecStart=/home/omero/omerowebvenv/venv/python /home/omero/OMERO.py/bin/omero web start
ExecStop=/home/omero/omerowebvenv/venv/python /home/omero/OMERO.py/bin/omero web stop

Hi Simon,
This seems to work however it still lacks something .... :)
Code: Select all
root@omero:/home/omero#>systemctl daemon-reload
root@omero:/home/omero#>systemctl enable omero-web.service
root@omero:/home/omero#>systemctl start omero-web.service

I did get any error message youpi. However, omero diagnostics still show that omero web is not started :evil:

Hi,
In fact the omero web server start from systemctl and the web page is ok. However, the omero diagnostics report that omero web is not started, I suppose that is because there is a lake of synchronization or connection between omero and the virtual env.

But when I try to connect this my brower have I login page without template I guest ????:


This normally means nginx can't access the statics directory (/opt/OMERO.server/lib/python/omeroweb/static). Is that the correct path? Elsewhere you're mentioned /home/omero/OMERO.py, maybe it's worth regenerating your config?

Could you check all files are world-readable, and all directories are world-executable, starting from /? Is there anything in /var/log/nginx/error.log? If SELinux is enabled could you also check
Code: Select all
audit2why < /var/log/audit/audit.log
audit2allow < /var/log/audit/audit.log


omero diagnostics report that omero web is not started

This only works when OMERO.server and OMERO.web are run together. We're moving towards decoupling the two, so in general that message is misleading. I'll add a ticket for it to be reviewed.

Hi,
I success now to start correctly omero.web thanks to your helps and suggestions. However, It still stay some "bugs" in the configuration. It seems that some config are not taking in account for example I have configured some options in the omero web as :
Code: Select all
omero@omero:~$>omero config get
omero.data.dir=/OMERO
omero.db.name=omero_database
omero.db.pass=*****************
omero.db.user=db_omero
omero.mail.config=true
omero.mail.host=smtp.college-de-france.fr
omero.web.apps=["omero_fpbioimage", "omero_iviewer", "omero_figure"]
omero.web.login_logo=/omero/static/webclient/image/logo_CIRB.jpg
omero.web.open_with=[["Image viewer", "webgateway", {"supported_objects": ["image"], "script_url": "webclient/javascript/ome.openwith_viewer.js"}], ["omero_fpbioimage", "fpbioimage_index", {"supported_objects": ["image"], "script_url": "fpbioimage/openwith.js", "label": "FPBioimage"}], ["omero_iviewer", "omero_iviewer_index", {"supported_objects": ["image"], "script_url": "omero_iviewer/openwith.js", "label": "OMERO.iviewer"}], ["omero_figure", "new_figure", {"supported_objects": ["images"], "target": "_blank", "label": "OMERO.figure"}]]
omero.web.ui.top_links=[["Data", "webindex", {"title": "Browse Data via Projects, Tags etc"}], ["History", "history", {"title": "History"}], ["Help", "http://help.openmicroscopy.org/", {"target": "new", "title": "Open OMERO user guide in a new tab"}], ["Figure", "figure_index", {"target": "_blank", "title": "Open Figure in new tab"}], ["Figure", "figure_index", {"target": "_blank", "title": "Open Figure in new tab"}]]
omero.web.viewer.view=omero_iviewer.views.index

And I didn't get the logo and the scripts on the web page. It's mentioned in your doc that these options are taking in account when you restart the omero web:
Note that depending on the deployment choice, OMERO.web will not activate configuration changes until gunicorn is restarted using bin/omero web restart.

However, I don't start the omero web server with this command because it give me a error. And it do not read correctly the config when with start omero as a ctl service ????

If you're using systemd it's best if you avoid running omero web commands directly- for instance your systemd service file takes care of activating the virtualenv which you'll otherwise have to do yourself. These three commands should all work:
Code: Select all
systemctl stop omero-web
systemctl start omero-web
systemctl restart omero-web

Hi,
I'm using systemctl to restart omero-web service. However, why configuration about scripts and logo image image are not read ???

Hi,

Any configs that start with "omero.web..." need to be configured on the OMERO.web deployment.

Code: Select all
$ OMERO.py/bin/omero config set omero.web.login_logo "/omero/static/webclient/image/logo_CIRB.jpg"


Hope that helps,

Will.
