安装HDP2.1 在注册ambari-agent发生的错

具体错误如下:
SSLError: Failed to connect. Please check openssl library versions

解决方案:
这是由于centos6.5(我们是用的这个)默认装的openssl的版本问题太低造成的,通过以下解决:
1、Check the OpenSSL library version installed on your host(s):
rpm -qa | grep openssl

openssl-1.0.1e-15.el6.x86_64
2、If the output says openssl-1.0.1e-15.x86_64 (1.0.1 build 15) you will need to upgrade the OpenSSL library by running the following command:
yum upgrade openssl

3、Verify you have the newer version of OpenSSL (1.0.1 build 16):
rpm -qa | grep openssl

openssl-1.0.1e-16.el6.x86_64

Restart Ambari Agent(s) and Click Retry Failed on the Wizard.
