Before You Begin

(Optional) Configure an HTTP Proxy

The Cloudera Manager installer accesses archive.cloudera.com by using yum on RHEL systems, zypper on SLES systems, or apt-get on Ubuntu systems. If your hosts access the Internet through an HTTP proxy, you can configure yum, zypper, or apt-get, system-wide, to access archive.cloudera.com through a proxy.

To do so, modify the system configuration on every cluster host as follows:

OS File Property
RHEL-compatible /etc/yum.conf proxy=http://server:port/
SLES /root/.curlrc --proxy=http://server:port/
Ubuntu /etc/apt/apt.conf Acquire::http::Proxy "http://server:port";
