HTTP Proxy

The Cloudera Manager installer accesses by using yum on RHEL systems. If your hosts access the Internet through an HTTP proxy, you can configure yum system-wide, to access through a proxy.

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

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


If you are using SELinux in enforcing mode, you must disable SELinux for the Cloudera Manager installer to work.

Configure SELINUX=disabled in the /etc/selinux/config file.


setenforce 0

Cluster Host

The hosts you intend to use must satisfy the following requirements:

  • You must be able to log in to the Cloudera Manager Server host using the root user account or an account that has passwordless sudo privileges.
  • The Cloudera Manager Server host must have uniform SSH access on the same port to all hosts.
  • All hosts must have access to standard package repositories for the operating system and either or a local repository with the required installation files.
