到配置mysql的步骤，到初始化数据库cloud时在命令行输入以下命令：
sudo cloud-setup-databases cloud:123456@localhost --deploy-as=root:123456 -e file -m cloudstack -k cloudstack
后，自动执行时老是到这里就出错（如下）
Applying /usr/share/cloud/setup/create-schema-premium.sql
We apologize for below error:
Encountering an error when executing mysql script
table:
/usr/share/cloud/setup/create-schema-premium.sql
Error:
ERROR 1046 (3D000) at line 285: No database selected
菜鸟求帮助～
