Not able to access Cloudera Manager Web UI

Hi,

 

I have successfully installed Cloudera Manager on RHEL 7 Azure VM but I'm not able to access the web ui. I have tried after adding 7180 port as inbound port in Network Security Group in azure portal.

When you see this log entry, the Cloudera Manager Admin Console is ready:

INFO WebServerImpl:com.cloudera.server.cmf.WebServerImpl: Started Jetty server

 

Try to access the CM API instead, you should use the login credentials 

curl -u <username>:password http://<cm_host>:<port>/api/v19/clusters

 

Are you able to reach out to the CM server from your desktop?

#ping cmserverhost

#telnet cmserverhost port

I'm using Windows 7(firewall and proxy disabled) and accessing the RHEL 7 VM through putty. I'm getting connection refused on using curl command. 

 

Here's the output for service cloudera-scm-server status-

/etc/init.d/cloudera-scm-server: line 109: pstree: command not found
● cloudera-scm-server.service - LSB: Cloudera SCM Server

Jul 07 08:52:42 vm2 systemd[1]: Started LSB: Cloudera SCM Server.

 

Here's the output for  netstat -na | grep 7180-

tcp 0 0 0.0.0.0:7180 0.0.0.0:* LISTEN

 

I have also checked  /var/log/cloudera-scm-server/cloudera-scm-server.log and there doesn't seem to be any errors. 

 

Any help is appreciated.

Correction : curl output

 

curl -i http://vm2:7180 gives following output-

    For this u dont need to add any properties..

    very simple just add the Inbound roles..

    like Http,Https and most important 7180 port no u should add this inside Azure NSG (inbound rule)..

     

    I have faced the same issue ..But Now i can get the cloudera Ui...
