Konfigurationsdatei – Nginx-Multi-Site-Konfiguration, der Zugriff über den Domänennamen ist nicht möglich. Bei Verwendung des IP-Zugriffs wird zu einer der Sites gesprungen

Question

Ich habe Nginx Multi-Site auf einem Server eingerichtet, aber auf die Domänennamen, die für den Zugriff auf diese Sites verwendet werden, kann nicht zugegriffen werden. Der Fehler ist wie folgt:

Sie werden über IP zu einer der Seiten weitergeleitet, und zwar wie folgt:

Wenn alle Konfigurationen aktiviert sind, kann nicht auf alle Domänennamen zugegriffen werden. SiteD
Nach dem Entfernen von SiteD springt es zu SiteB, nach dem Entfernen von SiteB springt es zu 404, nach dem Entfernen von SiteB springt es zu SiteA, und nach dem Entfernen von SiteA wird zu SiteC

gesprungen

Nach langer Suche weiß ich immer noch nicht, wo das Problem liegt. Bitte helfen Sie mir, das Problem zu beheben

Im Folgenden sind die spezifischen Konfigurationsdateien aufgeführt:

Answer 1

此问题已在v2ex获得解答，由@Showfom 解答，原因为域名没有备案，被机房屏蔽了

Answer 2

貌似缺省值的default，不用通配符比较好

server {
    listen 80 default;
    return 404 'no site found';
}

Answer 3

检查域名是否被有效的解析到服务器, 若未被正确解析, 在域名运营商处设置正确解析.

检查服务器防火墙设置, 时候开启 80 端口访问限制, 另也检查服务器运营商是否也有设置防火墙设定.

在配置好 nginx 后, 可在服务器进行测试是否可用.

curl siteA.domain.com

若域名处于未解析状态

echo '127.0.0.1 siteA.domain.com' >> /etc/hosts
systemctl restart nginx
curl siteA.domain.com

服务器若不能正常访问, 则问题出现在 nginx 配置上.
服务器若能访问, 而本地不行, 则问题就发生在域名解析或防火墙.

从我所知不多的 nginx 配置知识上来看, 没有太大毛病.
