I am trying to run Apache NiFi on my CentOS system. I downloaded it and run it with command:

/opt/nifi-1.1.1.0-12/bin/nifi.sh start

the result is here:

Java home: /usr/java/jdk1.7.0_45
NiFi home: /opt/nifi-1.1.1.0-12

then I check the status of Apache NiFi with command:

/opt/nifi-1.1.1.0-12/bin/nifi.sh status

and the result was:

Java home: /usr/java/jdk1.7.0_45
NiFi home: /opt/nifi-1.1.1.0-12

but at the end when I try to access to http://localhost:8090/nifi or http://localhost:8080/nifi on my browser it said : unable to connect. (I changed the http port to 8090 to avoid conflicts, but still have the same problem). Please help me, what is the problem?
