Opal Installation (Debian) fails to launch, missing env variables

[Ahmet Akkoç]

Hi,

I recently tried installing Opal as a Debian Package. Somehow, I think the environment variables OPAL_HOME, OPAL_DIST, OPAL_LOG and OPAL_ARGS are not created correctly.

--------

After following all instructions upto `sudo apt-get install opal`, I was unable to load web ui. Also `service opal` gives `opal: unrecognized service`.

Running systemctl:

```
# systemctl status opal.service
● opal.service - OBiBa Opal service
     Loaded: loaded (/lib/systemd/system/opal.service; enabled; vendor preset: enabled)
     Active: failed (Result: exit-code) since Wed 2024-01-17 22:21:24 UTC; 22min ago
   Main PID: 3024 (code=exited, status=127)

Jan 17 22:21:24 ubuntu-8gb-hel1-2 systemd[1]: Started OBiBa Opal service.
Jan 17 22:21:24 ubuntu-8gb-hel1-2 systemd[1]: opal.service: Main process exited, code=exited, status=127/n/a
Jan 17 22:21:24 ubuntu-8gb-hel1-2 systemd[1]: opal.service: Failed with result 'exit-code'.
```

The log file is also interesting:

/var/log/opal/stderr.log
```
/usr/share/opal/bin/start.sh: line 3: /usr/bin/java: No such file or directory
```

start.sh references OPAL_HOME and its sister OPAL variables:

```
#!/bin/bash

$JAVA $JAVA_ARGS -cp "${OPAL_HOME}/conf:${OPAL_DIST}/lib/*" -DOPAL_HOME=${OPAL_HOME} -DOPAL_DIST=${OPAL_DIST} -DOPAL_LOG=${OPAL_LOG} org.obiba.opal.server.OpalServer $OPAL_ARGS
```

When I check my env, these are missing.

If I restart opal.service from systemctl:
* The variables are seemingly loaded in correctly
```
/usr/bin/java -Xms1G -Xmx2G -XX:+UseG1GC -cp /var/lib/opal/conf:/usr/share/opal/lib/* -DOPAL_HOME=/var/lib/opal -DOPAL_DIST=/usr/share/opal -DOPAL_LOG=/var/log/opal  org.obiba.opal.server.OpalServer
```
* The web UI loads but log-in fails for the admin/password I chose.
* service opal remains unavailable.

Is there anything I am skipping here?

Machine Details:
* Ubuntu 20 (Freshly Spun-up)
* RAM: 8GB
* Storage: 80GB

Hi,

I assume that you had read this part. It looks like you do not have a Java installed, make sure you have Java 8. 

There is also a Docker version for Opal which I recommend, less messing around with your server, read info here.

Best,

[Ahmet Akkoç]

Okay this makes sense.

Before I would install MongoDB before Opal, inadvertently adding Java 8 in the process. I will see what happens if I install Java myself instead.

Thanks

Good news: java stopped the initial crash.

Bad news: There is still an issue when the admin password should have been updated during instalation.

What else could it be?

Opal needs Java 8 and if you are using Mongo, it should be installed prior to Opal installation.

Does Opal run at all? I mean, if you go to http://localhost:8080 (or your server address), do you see the login page? Maybe restart installation from scratch by purging the opal package and monitor /var/log/opal/opal.log once it loads up.

Opal runs now (if Java or Mongo is installed prior to opal)

It’s giving a new error when attempting to assign a password. 

See the line from above:

SLF4J: Failed to load class "org.slf4j.impl.StaticLoggerBinder".

Did you try a clean install, purge and install again?

I rebuilt the entire system.

This is to help me debug an active issue I have on an older installation of Opal.

There, updating the shiro.ini file does not reflect on the admin password, so I have been spinning up clean machines to try and find what causes the password update problem.

Seeing that I cannot update the admin password on the initial prompt on a clean install of Opal suggests that there is something funny going on.
