Help installing in CentOS Linux release 8.1.1911 (Core)

Hello all,
I really want to use this app but I cannot install it. I have done all steps in previous posts but still get an error:

[root@vmi343359 traccar]# sudo /opt/traccar/bin/traccar start
Starting traccar...
Waiting for traccar......
WARNING: traccar may have failed to start.
[root@vmi343359 traccar]#

And no response in my server address, can anyone help, please?

Have you checked logs or done any troubleshooting before posting here?

No, I dont know how, can you help?

I dont know how

That's why we have documentation. We also provide paid support for people who don't want to do work themselves.

I can pay for help, no one told me that. How do I find paid help?

Again, it's all on the website:

https://www.traccar.org/product/professional-services/

Once you make the payment, send an email to support address.

Sorry, cannot afford those prices. Thanks anyway

2 hours to install on Linux its a lot for me
