I Followed these steps :

First i took a server(Cent OS 6) from Google Cloud in Asia South reagion. and Executed these commands :

sudo -i
chkconfig iptables off
service iptables stop
setenforce 0
vi /etc/selinux/config (SELINUX=disabled)
init 6
wget http://archive.cloudera.com/cm5/installer/latest/cloudera-manager-installer.bin
chmod u+x cloudera-manager-installer.bin
sudo ./cloudera-manager-installer.bin

Done! Cloudera manager installed Successfully.

But when I am trying to access http://my_public_ip:7180/ then getting timed out error.

Also i waited for almost an hour after installing cloudera(for startup settings). but again same response.

Hello Gaurav,

Please share the output of curl on http://my_public_ip:7180 from cm host itself.

And tcpdump from the source host.

@Gaurav,

The first thing to check is whether the server is up and listening.

- service cloudera-scm-server status

- netstat -nap |grep 7180

Next, check the Cloudera Manager server log to find out if it had trouble starting.

- review /var/log/cloudera-scm-server/cloudera-scm-server.log

If you do find that Cloudera Manager is listening on 7180, make sure it is listening on all interfaces.

If you are getting a timed out message or a hang, that makes me suspicious that the server is coming up, but your route to that host is not working properly. Could there be a proxy configured in your browser that cannot connect to your CM server?

You might try tcpdump or browser developer tools to find out what the client/server communication looks like.

I'd start with making sure the server is listening on 7180 and review the log for any exceptions or errors that look important.

Hi @bgooley,

Thankyou for response.

here what i got

1. service cloudera-scm-server status

Running

2. netstat -nap |grep 7180

tcp        0      0 0.0.0.0:7180                0.0.0.0:*                   LISTEN      1623/java

and it seems that all right in log file.

Thankyou @bgooley for the help.

I Just figured it out by tcpdump. now it's working.

I am also facing the same issue, can you let me know how did you solve it

Hi @dewdrop,

Please see my initial comments in this thread. We'll need to know more about what you try to do and what the result is.

Thanks,

Hi,

I've installed cloudera Manager on Amazon VM Ec2 server.

disabled SELinux, disabled filewall setting

sudo service cloudera-scm-server status - up and running

netstat -nap |grep 7180
(No info could be read for "-p": geteuid()=1000 but you should be root.)
tcp 0 0 0.0.0.0:7180 0.0.0.0:* LISTEN

i tried these two on the running server

ec2-user@ip-172-31-44-224 ~]$ curl -i http://localhost:7180

{
"message" : "Hello, World!"

}

both returned an output,

However when trying to access the below url from chrome or fixefox i am getting the below error

http://ip-172-31-44-224.us-west-2.compute.internal:7180

Error :

We can’t connect to the server at ip-172-31-44-224.
If that address is correct, here are three other things you can try:

Any suggestions would be very helpful.

Thanks,

Hi @dewdrop,

Which Cloud Service are You using.
Have you allowed Port 7180 to access publicly?

dewdrop · ‎03-27-2018

EC2 and port 7180 is open for public access

[ec2-user@ip-172-31-44-224 ~]$ netstat -na | grep 7180
tcp 0 0 0.0.0.0:7180 0.0.0.0:* LISTEN
