我在启动ambari平台是遇到了问题：

[root@master ~]# ambari-server restart
Using python  /usr/bin/python
Starting ambari-server

......Unable to determine server PID. Retrying...
ERROR: Exiting with exit code -1. 
REASON: Ambari Server java process died with exitcode 1. Check /var/log/ambari-server/ambari-server.out for more information.

错误：退出并退出代码-1。原因：Ambari Server java进程因exitcode 1而死亡。检查/var/log/ambari-server/ambari-server.out以获取更多信息。
这个方法解决了我的问题，也希望能给你们一些帮助。
解决方法：
导入mysql脚本

1. mysql -uroot -pbigdata

2. mysql> use ambari; mysql> source
   /var/lib/ambari-server/resources/Ambari-DDL-MySQL-CREATE.sql;

但是我之前已经导入过脚本，不知道是哪里出现了问题，下面是我的过程

[root@master ~]# mysql -uroot -pbigdata
