nginx代理https访问

通过外部访问必须使用https访问,外部有其它域名的https证书也可以使用:

        listen   80 ;
        server_name  test.dashboard.cn;
            rewrite ^(.*) https://$server_name$1 permanent;

        error_page   500 502 503 504  /50x.html;
        location = /50x.html {
            root   html;
        }
    }

    server {
        listen   443 ssl;
        server_name  test.dashboard.cn;
        ssl_certificate      ssl/server.cer;
