Hi Juan,
I just wrote a service (based on
https://github.com/fhd/init-script-template) to run the glances webserver. You only need to modify line 14 in the file; change [YOUR_USER_NAME] to your user name, so it says something like this:
user="clrung"
Put this file in /etc/init.d/glances, assign it to the root user and root group (sudo chown root:root), and make it executable to the root user (sudo chmod 755 /etc/init.d/glances).
Next, run sudo service glances start, and the glances webserver should be up and running!
After a service is started, it will run at boot (that's what the Default-Start: 2 3 4 5 part of the script does).
