1 文档编写目的

本文档主要介绍如何为已经安装好的CDH集群配置Cloudera Manager启用TLS。

• 主要内容

1. Certificate Authority搭建

2. 创建节点证书

3. 配置Cloudera Manager Console使用TLS协议

4. Cloudera Manager Agents配置TLS

5. 配置Cloudera Manager Agents认证Server证书

6. 配置Cloudera Manager Server认证Agent证书

• 环境介绍

1. CDH6.1.0

2. RedHat7.2

2 Certificate Authority搭建

由于CDH集群大部分都是在内网当中，无法用到PUBLIC CA，因此需要搭建内网CA，这里使用OpenSSL Certificate Authority。

2.1 Root CA

1. 创建文件夹存放keys和certificates
   mkdir /root/ca
   
2. 在该目录下创建根CA的目录结构

cd /root/ca
mkdir certs crl newcerts private
chmod 700 private
touch index.txt
echo 1000 > serial

3. 准备配置文件/root/ca/openssl.cnf,内容如下：

[ ca ]
# `man ca`
default_ca = CA_default
[ CA_default ]
# Directory and file locations.
dir               = /root/ca
