解決辦法1：
地址：http://stackoverflow.com/questions/38423925/ambari-confirm-hosts-step-fails-registration-with-the-server-failed
說明：中文和英文作業系統版本問題，中文作業系統出錯，英文則成功；
Hey,thank both of you.i got it.The character in China is UTF8,and Ambari is ascii.And Python 2.6 for UTF8 has a bug.
和
I think this is because I set a non-English language (i.e,. Trad. Chinese) as a default language when I installed CentOs 7. It would encounter a charset problem (UTF-8<->ascii) when confirming hosts. After changing the default language to English, This problem has been solved.
解決方法是將系統的預設語言改成英語。
解決辦法2：
最有效的方式就是關閉 openssl 的檢查
sed -i 's/verify=platform_default/verify=disable/' /etc/python/cert-verification.cfg source /etc/python/cert-verification.cfg
解決辦法3：
若還是不能註冊ambari-agent,使用下面介紹的方式。
如果上面方式還不能註冊，說明jdk版本不通過，使用預設oracle啊jdk，博主是（centos7.3，所以選擇jdk1.8）
（1）先停掉：ambari-server stop；
（2）解除安裝掉所有節點agent:rpm -qa | grep ambari-agent 得到對應版本，使用rpm -e ambari-agent-XXX解除安裝；
（3）啟動setup：ambari-server setup，配置你的東西，直到選擇jdk如下圖：
這裡，選擇3
然後，yum -y install ambari-agent
等下載安裝完成，繼續後續步驟。直到結束
（4）啟動ambari：ambari-server start
（5）配置ambari即可正常註冊ambari-agent
