jar installation with ssl reverse proxy

[m7-marcus]

Hello,

I’m trying to run the embedded tomcat with apache2 as reverse proxy. Icescrum is invoked by
java -Xmx512M -XX:MaxPermSize=256m -jar icescrum.jar acontext=/

Apache is configured as follows:
ProxyRequests Off
ProxyPreserveHost On
ProxyStatus On
ProxyPass / http://public_ip:8080/
ProxyPassReverse / http://public_ip:8080/

When I try to access https://mydomain.com in a browser, I get redirect to http://public_ip:8080.
Any idea, how to solve this?

Thanks and regards,
Marcus

Hello Marcus,

With the jar installation you cannot use an reverse proxy in front of iceScrum. Why? Because as you seen the address used in your browser must be the same as the one registered in the config. This config grails.serverURL variable is dynamically set using jar installation.

In your case, you should have :

java -Xmx512M -XX:MaxPermSize=256m -jar icescrum.jar context=/ host=mydomain.com port=443

but your apache will be useless.

So you will need to go to more customized setup: https://www.icescrum.com/documentation/application-server/#application-server_2

Hi Vincent,

Thank you for your reply.

I guess that means, it’s not possible to combine the standalone installation with a reverse proxy?

I tried with tomcat, but ran into another issue. CSS and JS don’t load properly. I get the following errors:

I configured apache like here:
https://www.icescrum.com/documentation/application-server/#proxy-ssl_1

So:

Servername icescrum.mydomain.com
SSLStuff
...
ProxyRequests Off
ProxyPreserveHost On
ProxyStatus On
ProxyPass        / http://tomcat_ip:8080/icescrum/
ProxyPassReverse / http://tomcat_ip:8080/icescrum/

My config.groovy:

dataSource.password="mypass"
icescrum.baseDir="/usr/share/tomcat7/icescrum"
dataSource.driverClassName="com.mysql.jdbc.Driver"
dataSource.username="icescrum"
icescrum.login.retrieve.enable=false
icescrum.project.import.enable=true
icescrum.log.dir="logs"
grails.serverURL="https://icescrum.mydomain.com"
icescrum.alerts.enable=false
icescrum.gravatar.enable=false
icescrum.project.private.default=false
icescrum.project.creation.enable=true
icescrum.invitation.enable=false
icescrum.project.private.enable=true
icescrum.debug.enable=false
dataSource.url="jdbc:mysql://localhost:3306/icescrum?useUnicode=true&characterEncoding=utf8"
icescrum.project.export.enable=true
icescrum.registration.enable=false

How to resolve that?

Thanks and regards,
Marcus

Hello Marcus,

We “iceScrum standalone” stands for both the .jar and the .war versions, “standalone” just means that you install iceScrum on your own server rather than on our Cloud.

I confirm that the .jar version cannot be used in combination with a reverse Proxy, whereas the .war version with a custom Tomcat can!

You are heading in the right direction, but there are two remaining problems:

• The context name (here the /icescrum that comes at the end of the iceScrum URL) must be the same for the public URL and internal URL (it’s a limitation of a library we use).
  That means that you can either have
  – http://tomcat_ip:8080/icescrum/ and https://icescrum.mydomain.com/icescrum
  – or http://tomcat_ip:8080/ and https://icescrum.mydomain.com, which seems to be better. To make iceScrum start on the empty context on Tomcat, rename icescrum.war to ROOT.war and restart Tomcat
• You didn’t change the connector to be NIO and iceScrum will not work properly with BIO, change it in your server.xml as explained in the documentation: https://www.icescrum.com/documentation/application-server/

[m7-marcus]

Hi Nicolas,

thank you for your reply. I changed the connector to NIO and moved the war file to tomcat’s root. Proxying now works as expected, but unfortunately I still get some errors:
2016-03-11 10:44:13,841 [http-nio-127.0.0.1-8080-exec-4] ERROR org.grails.plugin.resource.ResourceMeta - Resource not found: /icescrum/plugins/icescrum-plugin-chat-0.1/js/flXHR/checkplayer.js

I tried reinstalling icescrum, I cleared the folders

/var/lib/tomcat7/work
/usr/share/tomcat7/icescrum
/usr/share/tomcat7/.icescrum
/tmp/hsperfdata_tomcat7

and the database. Now I get stuck in an endless loop throwing the above error when accessing /setup.

Any suggestions?

Thank you and regards,
Marcus

[Nicolas Noullet]

Did you rename the .war file to ROOT.war ?

[m7-marcus]

Yes, I have.

[Vincent Barrier]

Did you find a solution? If not, could we do a remote access session?

[m7-marcus]

Unfortunately no solution yet.

An SSH session would be possible. Could you send me your public key to marcus@module-7.com?

Thanks and regards,
Marcus

I checked icescrum’s log during autodeployment and startup. Contains some warnings and errors, too. Maybe full output is helpful?
