Question

我们将上周五的一个网站迁移到运行nginx 1.10.3 + ngx_pagespeed的新服务器1.11.33.4：

Nginx配置了两个主机：

PHPMyAdmin - pma.mydomainname.com

    server {

        listen 80;

        server_name pma.MYDOMAINNAME.com;

        root /usr/share/phpmyadmin/;
        index index.php;

        # set expiration of assets to MAX for caching
        location ~* \.(ico|css|js)(\?[0-9]+)?$ {

            expires max;
            log_not_found off;
        }

        location ~* \.php$ {

            fastcgi_pass unix:/var/run/php/php7.0-fpm.sock;
            fastcgi_index index.php;
            fastcgi_split_path_info ^(.+\.php)(.*)$;
            include fastcgi_params;
            fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        }
    }

网站本身 - www.MYDOMAINNAME.com

    server {
        listen 80;

        server_name MYDOMAINNAME.com www.MYDOMAINNAME;

        return 301 https://www.MYDOMAINNAME.com$request_uri;
    }

    server {

        listen 443 ssl http2;

        server_name www.MYDOMAINNAME.com;

        ssl on;
        ssl_certificate /etc/nginx/ssl/certificate.ca-bundle;
        ssl_certificate_key /etc/nginx/ssl/certificate.key;
        ssl_prefer_server_ciphers on;
        ssl_ciphers EECDH+CHACHA20:EECDH+AES128:RSA+AES128:EECDH+AES256:RSA+AES256:EECDH+3DES:RSA+3DES:!MD5;
        ssl_dhparam  /etc/nginx/ssl/dhparam.pem;
        ssl_session_cache shared:SSL:5m;
        ssl_session_timeout 1h;

        error_log /var/log/nginx/DOMAIN_error.log debug;
        access_log /var/log/nginx/DOMAIN_access.log;

        root /var/www/www.MYDOMAINNAME.com/web;
        client_max_body_size 25M;

        }

        location ~ \.php$ {
            rewrite (.*) /app.php/not-found;
        }

}

因为我们在周末看到了30％的流量下降，所以我查看了日志，我看到了一些奇怪的消息：

2017/04/03 06:24:47 [error] 6667#6667: *1093138 open() "/usr/share/phpmyadmin/FULL-REQUEST-PATH-HERE" failed (2: No such file or directory), client: <IP>, server: pma.MYDOMAINMANE.com, request: "GET /FULL-REQUEST-PATH-HERE HTTP/1.1", host: "www.MYDOMAINNAME.com"

它基本上将请求路由到www.MYDOMAINNAME.com到pma.MYDOMAINNAME.com但请求标头中的主机名实际上是www.MYDOMAINNAME.com

为什么nginx从错误的server_name提供内容？
