Unable to complete cmdbuild/openmaint database setup

  • 772

I'm attempting to install Openmaint on ubuntu 20.04. I'm almost at the final hurdle and I cant solve this.

At the openmaint database configuration page, I can succesfully connect to the database but then cannot save the database.conf file. This is the error

java.lang.RuntimeException: error saving config to file for namespace = org.cmdbuild.database, caused by: org.apache.commons.configuration.ConfigurationException: Unable to save to file /var/lib/tomcat9/conf/openmaint/database.conf, caused by: java.io.FileNotFoundException: /var/lib/tomcat9/conf/openmaint/database.conf (Read-only file system)

The file is definitely there and it's already configured with correct variables. Tomcat user definitely has write permission. If I delete the file, I only get an error about read-only file system.

Can anyone help please?

tomcat cmdb

  1. Solved by editing the systemd service file for tomcat. Systemd sandboxes file access and it's necessary to place an explicit file path in the service file to allow access.
