Keifer, thanks,

Try navigating to /var/log/tor/. This is where tor will normally save the log files to. See if there is a tor log text file there. If you have not started your relay, tor might not have created the log file yet.

Try starting the tor software then see if the file appears after that.

As it showed before there is no /var/log/tor.
I thought I installed it from root but typing tor as root brought 
/var/lib/tor is not owned by this user (root, 0) but by debian-tor (107)
Failed to parse/validate config: Couldn't create private data directory "/var/lib/tor"
