Unable to run yum update on centos 7

Not able to run yum update. It fails with the message connection refused.

When I run sudo yum update I get the following message

Loaded plugins: fastestmirror
Loading mirror speeds from cached hostfile
Could not retrieve mirrorlist error was
14: curl#7 - "Failed connect to localhost:3000; Connection refused"

I am able to connect to internet.

This is my solution.

1. Find your appropriate version on next site (in this example I'm using 7.0.1406):

2. Execute next commands to update your yum configuration files:

   sed -i -e 's/mirrorlist=/#mirrorlist=/g' /etc/yum.repos.d/CentOS-*

   sed -i -e 's/mirrorlist=/#mirrorlist=/g' /etc/yum.conf

   sed -E -i -e 's/#baseurl=http:\/\/mirror.centos.org\/centos\/\$releasever\/([[:alnum:]_-]*)\/\$basearch\//baseurl=https:\/\/vault.centos.org\/7.0.1406\/\1\/\$basearch\//g' /etc/yum.repos.d/CentOS-*

   sed -E -i -e 's/#baseurl=http:\/\/mirror.centos.org\/centos\/\$releasever\/([[:alnum:]_-]*)\/\$basearch\//baseurl=https:\/\/vault.centos.org\/7.0.1406\/\1\/\$basearch\//g' /etc/yum.conf

Good Luck!
