Question

我有一个目前在Apache中定义的简单API，其定义如下：

<VirtualHost *:80>
ServerName http://exampleapi.org
ServerAlias http://exampleapi.org
ProxyPreserveHost On
ProxyPass /api http://localhost:3000
</VirtualHost>

出于各种原因，我需要迁移Nginx，因此在/etc/nginx/conf.d/<domain>.conf中，我选择了：

server {
  listen 80;
  listen [::]:80;

  server_name http://exampleapi.org;
  # API endpoint
  location = / {
    proxy_pass http://127.0.0.1:4000;
  }
}

问题似乎是我在/etc/nginx/conf.d/<domain2>.conf中有另一个文件/站点，并且它总是与之匹配，正如我从访问日志中清楚看到的那样。那么它在其他配置中与所有内容匹配吗？（请注意，example.com等站点名称已被<domain>所迷惑。）

server_name指令是要查找的主机头值。它不包含协议。

server {
    listen 80;
    listen [::]:80;

    server_name exampleapi.org;
    # API endpoint
    location / {
        proxy_pass http://127.0.0.1:4000;
    }
}

另外，请注意，我将location = /更改为location /，因为使用=只会匹配确切的路径，我认为这不是计划。

Nginx反向代理不匹配主机名
