This is how to setup a basic Rsyslog server and building a database. Rsyslog connects the applications on the users computer to the databases and the dashboard and management of the log server.
On client, add server address with syslog-server to /etc/hosts.
On server, install rsyslog with apt-get and check with systemctl status rsyslog. Enable TCP Protocol and UDP Protocol in /etc/rsyslog.conf. Restart with systemctl restart rsyslog.
