I am just starting to try out Mesos. I followed the instructions to get the master installed. For now, I am using a single master (with 3 slaves). I am installing on CentOS 6.5 - which is a Virtual Machine, terminal only.
The problem I am having is that if I navigate to port 5050 on that virtual machine from my desktop browser, I get no response.
However, from a terminal window if I do:
curl http://localhost:5050/
I get back an AngularJS page. Which looks in part like:
<!DOCTYPE html>
<html lang="en" ng-app="mesos">
<head>
<meta charset="utf-8">
<title>Mesos</title>
<meta name="viewport" content="width=device-width, initial-scale=1.0">

<link rel="shortcut icon" href="/static/ico/favicon.ico">
</head>
<body>
<div data-ng-show="doneLoading" style="width: 75px; margin: 0 auto; text-align: center;">
If I ping the VM from my desktop, that works fine too. However, if I use the curl command from my desktop (using the 'IP ADDRESS':5050), I get "couldn't connect to host"
Anyone with suggestions on what I might try to get this to work properly?
New Information
I ran netstat on the VM. It gives me:
netstat -tapen | grep 5050
tcp 0 0 0.0.0.0:5050 0.0.0.0:* LISTEN 0 21589 2852/mesos-master
I suspect that is telling me what is wrong, but not sure how to fix it! Also, running nmap from my desktop machine and scanning ports 5000-5100 on the VM shows all 101 ports closed.
Depends on what VM networking mode you're using. If the VM has an external IP (like 10.0.2.15), then you may be able to reach Mesos on http://10.0.2.15:5050, otherwise you may need to set up port forwarding or bridged/host-only networking modes.
