SSL for masses

Motivation

 I expanded my tool for enabling wired encryption in the HDP cluster.

Previously, only self-signed certificates were supported. I added automation for CA-signed certificates. Important: it works only if CA-signed certificate package follows the supported format.

There are two paths possible: self-signed certificates and CA-signed certificates.

Self-signed certificates

  1. ./run.sh 0 Creates self-signed certificate and truststores for every node.
  2. ./run.sh.1 Creates and distributes all-client truststore.
  3. ./run.sh 2 Secure keystores and truststores. Apply owner and Linux permissions.
CA-signed certificates
  1. ./run.sh 3 Creates self-signed certificates and CSR (Certificate Signing Request) for every node
  2. Manual step. Send all CSR to CA centre for signing. The CA-signed certificates  should be stored in a designed format.
  3. ./run.sh 4 CA-signed certificates are imported into corresponding keystore and replacing the self-signed certificates. Truststores are created.
  4. ./run.sh 1 Creates and distributes all-client trustore.
  5. ./run.sh 2 Secure keystores and trustores.

There is a number of pages containing practical steps on how to enable SSL for HDP components. It is based on documentation but more practical based on experience. 

For instance:

HDFS Ranger Plugin for SSL

NiFi service for SSL
