Omero web on separate machine

[Gebhard]

Hi guys,

I've just upgraded to OMERO 5.4 ; The upgrade from 5.3.1 to 5.4 went very smoothly!

Now, I'm trying to setup a machine which is only running omero web.
Omero web itself is running.
In my nginx conf I've set the upstream server to the IP of the actual Omero server and the port is 4080.
However, on the Omero server port 4080 is listening on 127.0.0.1 and thus refusing the connection.

How can I "convince" Omero to accept incomming connections from my webserver(s) [there might be more in the future]? Or, do I have to specify another port in my nginx config?


Best,
Gebhard

Hi Gebhard,

the property you're looking for is omero.web.application_server.host. See https://docs.openmicroscopy.org/omero/5.4.0/sysadmins/unix/install-web.html#customizing-your-omero-web-installation for more information.

Cheers,
~Josh.

So, omero web and omero have to be on the same machine, only nginx can be run on a separate server?

I've used omero.web.applicaiton_server , omero.web.applicaiton_server.host and omero.web.applicaiton_server.port to adjust my configuration and then the omero web config nginx command to generate the configuration file.

No. They can all be on different machines.

I've used omero.web.application_server , omero.web.application_server.host and omero.web.application_server.port to adjust my configuration and then the omero web config nginx command to generate the configuration file.

Can you perhaps paste us your configuration from nginx as well as

Code: Select all

bin/omero config get --hide-password


?

Thanks,
~Josh.

Hi Gebhard,

Ah, ok. Then NGINX should in fact use localhost. NGINX talks to OMERO.web and OMERO.web talks to OMERO.server. Port 4080 belongs to OMERO.web and so *shouldn't* be open on 10.60.8.228, but instead on the machine where NGINX and OMERO.web are running.

omero.web.application_server.host tells Django (i.e. OMERO.web) which interface to listen on.

omero.web.server_list defines the logins available to the end-user and points to OMERO.server, but the port should be 4064 (which should be open on 10.60.8.228).

Cheers,
~Josh.

Hi Josh,

this seems to go into the right direction, however, now I get
Invalid SERVER_LIST (omero.web.server_list = '[[10.60.8.228,4064,omero]]'). Expecting , delimiter: line 1 column 8 (char 7). A list of servers the Web client can connect to.
when I try to restart omero.web, but I don't see what's wrong...


Best,
Gebhard

Hi Gebhard,

you're missing quotes around "OMERO". That property is parsed as JSON so strings need to be quoted.

Cheers,

Here's what I do

Code: Select all

bin/omero config set omero.web.server_list [["10.60.8.228",4064,"omero"]]

I also tried

Code: Select all

bin/omero config set omero.web.server_list [['10.60.8.228',4064,'omero']]

but the result is still the same.

Also, if I look at etc/grid.config.xml the quotas are always gone

[jmoore]

Your shell is eating them. You can either use:

Code: Select all

bin/omero config edit


to not interact with the shell, or wrap everything in one more set of quotes:

Code: Select all

bin/omero config set omero.web.server_list '[["10.60.8.228",4064,"omero"]]'
