如何为不同的上下文 URI 配置位置指令

Question

发生了什么：

我使用以下 nginx.conf 文件进行负载平衡。 Web 应用程序已启动并且运行在 nginx 8080 端口上并且能够访问登录页面。但是，当从着陆页移动到 "signup" 页面时，它会抛出错误。

期望值：

nginx 负载均衡器应该将负载重定向到 Location 指令中提到的页面。但这并没有发生。

nginx 文件:

events {

}

http {

upstream 3.121.253.126 {
    server 3.121.253.126:8080;
    server 3.121.253.126:8080;
    server 3.121.253.126:8080;
 }
  error_log /etc/nginx/error_log.log warn;
  client_max_body_size 20m;

  proxy_cache_path /etc/nginx/cache keys_zone=one:500m max_size=1000m;

  server {
    listen 8080;
    server_name 3.121.253.126;
    root /etc/nginx/html;
    index index.html;

    location /signup {
      root /etc/nginx/html;
      index add-user.html;

    #  proxy_pass http://localhost:8080/signup;
    #  proxy_set_header Host $host;
   #   rewrite ^/welcome(.*)$  break;
    }

  }

}

这是错误日志：

2019/02/21 09:07:42 [error] 6#6: *510 recv() failed (104: Connection reset by peer) while reading response header from upstream, client: 127.0.0.1, server: 3.121.253.126, request: "GET /signup HTTP/1.0", upstream: "http://127.0.0.1:8080/signup", host: "localhost:8080", referrer: "http://3.121.253.126:8080/" 2019/02/21 09:07:42 [warn] 6#6: *510 upstream server temporarily disabled while reading response header from upstream, client: 127.0.0.1, server: 3.121.253.126, request: "GET /signup HTTP/1.0", upstream: "http://127.0.0.1:8080/signup", host: "localhost:8080", referrer: "http://3.121.253.126:8080/" 2019/02/21 09:13:10 [error] 6#6: *1 open() "/etc/nginx/html/signup" failed (2: No such file or directory), client: 157.33.175.127, server: 3.121.253.126, request: "GET /signup HTTP/1.1", host: "3.121.253.126:8080", referrer: "http://3.121.253.126:8080/" 2019/02/21 09:15:57 [error] 6#6: *3 open() "/etc/nginx/html/signup" failed (2: No such file or directory), client: 157.33.175.127, server: 3.121.253.126, request: "GET /signup HTTP/1.1", host: "3.121.253.126:8080", referrer: "http://3.121.253.126:8080/"

根据日志，需要注册 html 文件。但是，我指示它使用 add-user.html 文件。不确定为什么没有发生这种情况。

请推荐

您想将 URI /signup 指向位于 /etc/nginx/html/add-user.html

的文件

有很多方法可以使用 Nginx 实现这一点，包括 rewrite 和 try_files 指令。

例如：

location /signup {
    try_files /add-user.html =404;
}

不需要在此 location 块中重复 root 指令，因为它将从周围的块继承相同的值。

=404 什么都不做，因为 add-user.html 总是存在，但是 try_files 需要两个参数。有关详细信息，请参阅 this document。

以上位置将处理任何以 /signup 开头的请求（例如 /signup/ 或 /signups）。

要将其限制为单个 URI /signup，请使用 = 修饰符。有关详细信息，请参阅 this document。

例如：

location = /signup {
    try_files /add-user.html =404;
}
