I registed my domain "wanghongmeng.com" on Aliyun, and applied free EC2 server for one year on AWS.

After building my blog on AWS, I set A parse to the server's IP of AWS.

But yesterday I received email from Aliyun which said that my server was not in Aliyun after they checking, it was not allowed, I have to miggrate my blog server to Aliyun, otherwise they will undo my authority number.

After thinking about this, for saving money(Aliyun is not free for one year), I solved it by the way below:

1.Set A parse to my friend's server ip which was bought in Aliyun.

I thought something before, when I check nginx's log, I found a wired hostname.

After checking, I think out website was mirrored.

I think they parsed their domain by CNAME to our domain, and we don't do any host check at that time.

To prevent being mirrored again, I add host check configuration in nginx.conf

set $flag 0;
