Annis as a service in `/etc/systemd/system`

[gcelano]

There is a problem with Annis finding the directory for the database in application.properties. If I leave the default values

annis.webservice-config=${user.home}/.annis/service.toml
spring.datasource.url=jdbc:h2:file:${user.home}/.annis/v4/frontend_data.h2

Annis starts, but no database is shown. In fact, my system user/group is annis, and therefore I guess there may be a problem with the value of ${user.home}, because the database is in /home/celano/.annis ...

If I try to substitute ${user.home} with /home/celano/, then I get the error:

java.net.ConnectException: Failed to connect to localhost/[0:0:0:0:0:0:0:1]:5711

Can you post your /etc/systemd/system/annis.service file? It looks, indeed, that the service is or was started as the wrong user. Please also post the output of the command

sudo systemctl status annis.service

The application.properties file is located in another users' home folder, which might be a problem when the process running as annis user tries to access it because it might lack the access right for this. I would check if the annis user and its home directory /home/annis/ actually exists and move all files to the /home/annis/ directory so it is always accessible for the annis user.

Or as an alternative, you could the service to use the celano to start the service.

[Unit]
Description=ANNIS corpus search and visualization

[Service]
Type=simple
ExecStart=/usr/local/bin/annis-gui-4.12.2-server.jar --spring.config.location=file:/home/celano/.annis/application.properties
Environment=""
User=celano
Group=celano
WorkingDirectory=/usr/local/bin

[Install]
WantedBy=multi-user.target

Then, the ${user.home} placeholde should be resolved correctly.

annis.webservice-config=${user.home}/.annis/service.toml
spring.datasource.url=jdbc:h2:file:${user.home}/.annis/v4/frontend_data.h2

I have moved /.annis to the home directory of the user annis, changed file ownership, and now it works.
