我的aws弹性beantalk日志文件中的Nginx错误

Question

我已经在配置了 nginx 服务器的弹性 beanstalk 上部署了我的 nodejs rest API，我收到以下错误：

2021/03/03 15:01:15 [error] 18614#0: *1381 upstream prematurely closed connection while reading response header from upstream, client: 172.31.17.180, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8080/", host: "172.31.43.117"

2021/03/03 15:01:30 [error] 18614#0: *1385 upstream prematurely closed connection while reading response header from upstream, client: 172.31.17.180, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8080/", host: "172.31.43.117"

2021/03/03 15:01:45 [error] 18614#0: *1389 upstream prematurely closed connection while reading response header from upstream, client: 172.31.17.180, server: , request: "GET / HTTP/1.1", upstream: "http://127.0.0.1:8080/", host: "172.31.43.117"

我已经尝试了很多东西，还在我的根目录中添加了一个 .ebextensions 文件夹，其中包含一个名为 nginx.config 的文件，该文件具有以下配置，由 aws 文档提供，但它似乎仍然不起作用。我花了 3 天时间试图解决这个问题，但我无法解决。如果有人能帮我解决这个问题，我将不胜感激

我的nginx配置如下：

files:
/etc/nginx/conf.d/proxy.conf:

owner: root
group: root

  upstream nodejs {
    server 127.0.0.1:5000;
    keepalive 256;
  }

  server {
    listen 8080;

    if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})T(\d{2})") {
        set $year $1;
        set $month $2;
        set $day $3;
        set $hour $4;
    }
    access_log /var/log/nginx/healthd/application.log.$year-$month-$day-$hour healthd;
    access_log  /var/log/nginx/access.log  main;

    location / {
        proxy_pass  http://nodejs;

        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    gzip on;
    gzip_comp_level 4;
    gzip_types text/html text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

    location /static {

    }

Answer 1

您尝试使用的 nginx 设置 (/etc/nginx/conf.d/proxy.conf) 适用于 Amazon Linux 1。

由于您可能使用的是 Amazon Linux 2 (AL2)，因此您应该使用不同的文件来设置 nginx。对于 AL2，nginx 设置应在.platform/nginx/conf.d/ 中，而不是在.ebextentions 中，如docs 中所示。或者，如果您想完全覆盖主要的 nginx.conf，您应该使用 .platform/nginx/nginx.conf 提供其自定义版本。

假设你的 nginx 配置没问题，你可以尝试创建文件.platform/nginx/conf.d/myconf.conf，内容为：

  upstream nodejs {
    server 127.0.0.1:5000;
    keepalive 256;
  }

  server {
    listen 8080;

    if ($time_iso8601 ~ "^(\d{4})-(\d{2})-(\d{2})T(\d{2})") {
        set $year $1;
        set $month $2;
        set $day $3;
        set $hour $4;
    }
    access_log /var/log/nginx/healthd/application.log.$year-$month-$day-$hour healthd;
    access_log  /var/log/nginx/access.log  main;

    location / {
        proxy_pass  http://nodejs;
        proxy_set_header   Connection "";
        proxy_http_version 1.1;
        proxy_set_header        Host            $host;
        proxy_set_header        X-Real-IP       $remote_addr;
        proxy_set_header        X-Forwarded-For $proxy_add_x_forwarded_for;
    }

    gzip on;
    gzip_comp_level 4;
    gzip_types text/html text/plain text/css application/json application/x-javascript text/xml application/xml application/xml+rss text/javascript;

    location /static {
        alias /var/app/current/static;
    }

  }
