You are missing Java or Java is misconfigured.

root@vps [/opt]# java -version
java version "1.7.0_67"
Java(TM) SE Runtime Environment (build 1.7.0_67-b01)
Java HotSpot(TM) 64-Bit Server VM (build 24.65-b04, mixed mode)

how can I set java to traccar

You need to install Java properly so it's available on the path for all users. Remember that Traccar runs as a system service. It's not the same environment as your shell.

in which directory must be installed jdk?

Just install it using package manager.

I have linux centos

This is how you install Java on CentOS:

sudo yum install java-1.7.0-openjdk

I'm not sure what directories you are talking about.

Thank you very kind and expert!.
