Change Ambari server from TCP6 to TCP

Expert Contributor

Hello All,

I have installed ambari and it got successfully got running on a vm.

but when i check ipaddress:8080, it is not getting access.

When i run the command netstat -nl | head


Active Internet connections (only servers)

Proto Recv-Q Send-Q Local Address Foreign Address State

tcp6 0 0 :::5901 :::* LISTEN

tcp6 0 0 :::8080 :::* LISTEN
tcp6 0 0 :::8081 :::* LISTEN

it is running under tcp6 protocal.

how can i make it to run under tcp so that i can access through out the network.

Any suggestions,


Mohan V

Your answer is just for httpd, not for Ambari

Cloudera Employee

# vi /etc/sysctl.conf
net.ipv6.conf.eth0.disable_ipv6 = 1

and then restart you Ambari server:

sudo ambari-server restart


What are the impacts on other ports if I change from TCP6 to TCP? And will my Ambari server work on TCP?
