Installation/configuration stuck on setup/dosetupstart.action page

[Armin Müller]

Hi,

I'm trying to install a Confluence trial on an Ubuntu 18.04.4 LTS box, using the installer method. Everything works fine until I get to the setup/dosetupstart.action page which comes up like attached below.

There are no suspicious outputs in the tomcat logs, and I tried this both with the JRE which ships with Confluence and the default OpenJDK 64-Bit Server VM (25.242-b08) for linux-amd64 JRE (1.8.0_242-8u242-b08-0ubuntu3~18.04-b08) on that box.

Also no errors in the browser console.

Jira already runs without problems on the same box.

Thanks,
Armin

@Armin Müller  Could you show the Confluence logs  files in <confluence_home>/logs  there could be  some information there.

[Armin Müller]

Here you go:

startup log (the Ctrl+C was after the test obviously):

https://justpaste.it/3n1oa 

catalina log:

https://justpaste.it/4nb38 

gc log;

@Armin Müller  Most likely you will need to  disable Firewall / SeLinux / Apparmor  in  Ubuntu server and try again

[Armin Müller]

I've temporarily disabled the firewall (ufw disable) (there was/is an allow rule for the port I'm trying to run confluence on, otherwise, I couldn't have accessed the setup page at all) and app-armor (systemctl stop apparmor), there's no SELinux in that box.

-> no change in behaviour

I am running the setup remotely, not on localhost - does that make a difference?

[Moses Thomas]

@Armin Müller  If the host  is running  in a  particular network,  then you need to access the link to  the setup in that network. If this is ok,  then  restart the installation it should work.

[Armin Müller]

Not sure if I understand you correctly: Are you saying I can only run the setup via http://localhost:8090/ and not remotely? This is difficult to accomplish on a headless server...

[Moses Thomas]

@Armin Müller  

OK let me explain, what i am saying is that since you are doing it remotely,

A- local host (your PC, IP.192.X.3.0.1)

B- Confluence server(Ubuntu host  192.X.1.0.1)

Firstly,you could have firewall/App-armor which is blocking complete access to  confluence Startup page (A) and (B)

If you are using Ubuntu on both host then disable app-armor.As for firewall i suggest you copy rules to word-pad and disable on  your PC, and then modify  fire  wall on confluence server to  access confluence so it will  be  http://<ip-adress>:8090

if you have other OS on your PC(for example windows make sure you modify firewall not to block anything).

[Armin Müller]

Turning off the firewall on my client Windows PC didn't change anything. But then, it's behind a router which doesn't know how to route incoming confluence related traffic anyway.

So for now, I picked a different Ubuntu box where I can start a browser to run the configuration on http://localhost:8090 - that worked.

So my conclusion is that remotely configuring confluence after the installation really doesn't work without further port forwarding on gateways etc. (and that is IMHO a real limitation).

As a side note: Remote configuration did work with Jira.

@Armin MüllerThis is networking Concept, Confluence is different app entirely, Confluence(tomcat)  needed  some external  resources  to  work properly which he is not able to  access.  JIRA is also  different app, so the behaviors are different.

Well  this  is not a limitation because  this is  how internet works,  you cannot access a app running on another host  via some port. via  your local host just like that  you  will  have to  configure that is(route,firewall) .

[Armin Müller]

Fine. At any rate, I can evaluate. Thanks.

@Armin Müller  You are welcome
