Registration with the server failed

可以看到 Connecting to Ambari server at https://slave1:8440 (10.10.22.203)

slave1是以前的hostname

解决方法：

修改ambari-agent hostname配置

vim /etc/ambari-agent/conf/ambari-agent.ini

把server hostname修改正确，改成ambari server安装的主机名，一般是master

然后重启ambari-agent

ambari-agent restart

然后点击back重新register就可以了
