Configure Ambari server to use a proxy server

You can configure Ambari Server to access the Internet using a proxy server.

1. On the Ambari Server host, stop Ambari Server.
   ambari-server stop
2. Add proxy settings to the following script: /var/lib/ambari-server/ambari-env.sh.
   -Dhttp.proxyHost=[YOUR_PROXY_HOST] -Dhttp.proxyPort=[YOUR_PROXY_PORT]
3. Optionally, to prevent some host names from accessing the proxy server, define the list of excluded hosts.
   -Dhttp.nonProxyHosts=[pipe|separated|list|of|hosts]
4. If your proxy server requires authentication, add the username and password.
   -Dhttp.proxyUser=[USER_NAME] -Dhttp.proxyPassword=[PASSWORD]
5. Restart the Ambari Server to pick up this change.
   ambari-server restart
