Error when trying to execute serve code

Hello,
First thank you for all you do, it a formidable work.

When I execute this in a server (aws ec2 with ubuntu)
java -jar tracker-server.jar conf/traccar.xml

I have this error:

Exception in thread "main" java.io.FileNotFoundException: ./logs/tracker-server.log (Permission denied)
	at java.io.FileOutputStream.open0(Native Method)
	at java.io.FileOutputStream.open(FileOutputStream.java:270)
	at java.io.FileOutputStream.<init>(FileOutputStream.java:213)
	at java.io.FileOutputStream.<init>(FileOutputStream.java:133)

	at org.traccar.Context.init(Context.java:273)
	at org.traccar.Main.main(Main.java:35)

There is no file in logs, should I create it?
Or how can I give the Permissions to traccar to do that?

Thank you

The problem seems to be with Linux file permissions. Maybe you don't have the "logs" folder?

I do have the logs folder, for now i didn’t change any permission. Should i change the permission of any file or folder?

Obviously process has to have access to the folder.

Thank you!

I resolved the problem by launching Traccar with admin access.
This line:
sudo java -jar tracker-server.jar conf/traccar.xml
Instead of this one:
java -jar tracker-server.jar conf/traccar.xml

Is it a good solution? is that secure?

I think it's fine. We usually run it from a root user.
