Question

我定义了两个等价 nginx指令，例如：

server {
    listen 80;
    server_name translations.example.com;

    location / {
        proxy_pass http://localhost:8080;
    }
}

server {
    listen 80;
    server_name img.example.com;

    location / {
        proxy_pass http://localhost:9069;
    }
}

但是，我发现第一个仅显示nginx欢迎页面（地址栏中有124.26.119.135），而第二个按预期工作（img.example.com并显示img-service）。

直接通过IP地址和端口访问服务对它们两者均有效（例如124.26.119.135:8080和124.26.119.135:9069）。

我看不出有什么区别吗？

nginx -t不返回任何错误或警告：

nginx: the configuration file /etc/nginx/nginx.conf syntax is ok
nginx: configuration file /etc/nginx/nginx.conf test is successful

进一步的分析表明，似乎存在一个重定向循环，不断获取301 Permanently moved，将translations.example.com重定向到124.26.119.135到124.26.119.135等。

nginx日志显示：

域似乎已正确配置：

host -t A translations.example.bot产生translations.example.com has address 124.26.119.135，对于img.example.com：img.example.com has address 124.26.119.135返回相同的结果。

重定向循环：Nginx仅显示特定子域的欢迎页面
