traccar service cannot be executed normally.

I installed traccar on CentOS according to the document at https://www.traccar.org/install-digitalocean/. When executing traccar service, the mysql table is generated, but traccar service cannot be executed normally. Can someone please help me?
Download and extract the installer package
Execute traccar.run file

sudo ./traccar.run

Start systemd service

sudo systemctl start traccar

[root@iZj6c7b8cg52hq2yie2lo1Z ~]# sudo systemctl status traccar.service

What is the problem with that?
