KeystoneERROR 1045 (28000):Access denied for user 'keystone'@'controller'(using password YES)HTTP500

错误如下：

问题分析：keystone创建服务时 HTTP500
接下来 我们使用keystone 用户登陆Mysql 数据库发现无法登陆，密码错误

解决方法：使用root用户登陆mysql 对keystone重新给予权限
grant all privileges on keystone.* to ‘keystone’@‘localhost’ identified by ‘000000’;
grant all privileges on keystone.* to ‘keystone’@’%’ identified by ‘000000’;

如果同步数据后，进入数据库查看，无数据，请看这篇博客https://blog.csdn.net/fly1574/article/details/87616984
