Not able to connect to cloudera manager admin console even after successful start

I am installing cloudera manager on a vm on amazon aws cloud.

I followed the instructions given

Please see my security group and you can see that I have opened the required inbound traffic

In my logs I can see that the cloudera-scm-server is starting correctly without any errors. the last line which I see in my log is

2015-06-05 23:26:45,222 INFO WebServerImpl:org.mortbay.log: jetty-6.1.26.cloudera.4
2015-06-05 23:26:45,231 INFO WebServerImpl:org.mortbay.log: Started SelectChannelConnector@0.0.0.0:7180

and yet when I put the public dns name of my VM http://<<public dns>>:7180/

it does not connect and just says "this web page is not available"

OK. I solved it.

it was my age old nemisis iptables.

I did these 2 steps to solve the problem

service iptables stop

chkconfig iptables off

now CM is appearning nice and easy in the browser.

This did not solve it for me. I am using AWS and 1GB of memory on my CMS. Could this be an issue with the HTTP service on port 7180 not allowing my page to pull up.

All my settings are the same as in this thread.

What else would cause the page not to be displayed?

Thanks

I was having the exact same issue, cannot hit the CM login using public DNS or IP on port 7180.

Following steps will help you :

iptables stopped (service iptables stop)  
SELinux disabled (got to /etc/selinux/config and disbaled the selinux)   
curl/wget localhost:7180 works (check the curl status)  
ufw allow 7180  
service httpd status should be running.  
check va/log/cloudera-scm-server log : if any error found then troubleshoot the error      
cloudera-scm-server status (should be running state)
netstat -nap | grep 7180 returns  (if running other service then kill it)
telnet localhost 7180 (should be connected)
