Registration with the server failed.主要是两个问题：
1、vim /etc/ambari-agent/conf/ambari-agent.ini
查看hostname是否改成本机的主机名；
输入hostname即可知道自己主机的hostname
2、中文和英文操作系统版本问题，中文操作系统出错，英文则成功；
centos6：
修改vim /etc/sysconfig/i18n
LANG="en_US.UTF-8"
SYSFONT="latarcyrheb-sun16"
centos7：
修改vim /etc/locale.conf
LANG="en_US.UTF-8"
LANGUAGE="en_US:en"
