proxy Aliyun's domain to AWS's server

proxy_aliyun_to_aws.md

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.

2.Add a piece of configuration in his nginx.conf:

server {
    listen  80;
    server_name  wanghongmeng.com www.wanghongmeng.com;

    location / {
        rewrite ^/(.*)$ https://$server_name/$1 permanent;
    }
}

server {
    listen 443;
    server_name wanghongmeng.com www.wanghongmeng.com;
    ssl on;
    ssl_certificate "Location of Pem File";
    ssl_certificate_key "Location of Key File";
    ssl_session_timeout 5m;
    ssl_protocols TLSv1 TLSv1.1 TLSv1.2;
    ssl_ciphers "Your Algorithm";
    ssl_session_cache shared:SSL:50m;
    ssl_prefer_server_ciphers on;

    location / {
        proxy_pass  http://AWS's IP:443/;
    }
}

3.Expose 443 port on my AWS, and only accept requests from my friend's server IP:

server {
    listen  443;
    
    set $flag 0;
    if ($host = 'www.wanghongmeng.com') {
        set $flag 1;
    }
    if ($host = 'wanghongmeng.com') {
        set $flag 1;
    }
    if ($flag = 0){
        return 403;
    }    
    
    location / {
        allow "My Friend's Server IP";
        proxy_pass  http://blog-ip;
    }
}

Things done!
