Localhost:7180 Connection Refused Cloudera Manager

[#1]

Hi,

I have an issue with localhost connecton to cloudera manager web ui. I installed CM via the installer.bin and if I try to connect to localhost, the connection gets refused.

The things I've checked are:

selinix disabled

firewalls disabled

cloudera server is running

port 7180 is open

Does anybody know how to fix this issue?

Thanks in advance

Do you have a password for a root user? You can always su root and open it with this user. Otherwise add your user to sudo group (https://www.digitalocean.com/community/tutorials/how-to-create-a-sudo-user-on-ubuntu-quickstart) and you will always be able to open a file adding sudo at the beginning of your command

Hope it helps!

Best

Anna

@DivyaniS,

What URL are you using in the browser?

What is the netstat -nap |grep 7180 output (when run on the Cloudera Manager host?)

What is the error you see exactly?

@iram,

You need to have permission in the OS file system to view the log file.  You will need sudo or root access.

Also note that I said "cloudera-scm-server.log", not the agent log.

I would recommend opening new threads for all of these as every issue here appears to differ and there would be no one solution.

Hi,

When I am rejected, I will first check if I have logged into the Oracle website. Then, I will log in to my registered email address. Then search for cloudera, cloudera will automatically log in to the "My Account Home" page.
You can try to see if this can help you.
