配置文件 - nginx多站点配置，无法通过域名访问，使用ip访问会跳转到其中一个站点-PHP中文网问答

在一台服务器设置了Nginx多站点，但是访问这些站点的域名均无法访问，错误如下图：

通过ip会跳转到其中一个站点，具体表现为：

全部配置开启的情况下所有域名无法访问，ip访问显示的是siteD
去除siteD后跳转siteB,去除siteB后404，去除siteB后跳转siteA，去除siteA后跳转siteC

检查了半天还是不知道是啥问题，请各位大神帮忙排查下/w

以下为具体配置文件：

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

貌似缺省值的default，不用通配符比较好

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

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.
