来自nginx的未知"服务器"变量

Question

我正在将容器化的nginx服务器部署到AWS上。但是，当我尝试访问它时，我从浏览器中收到"无法连接"错误。日志文件给我错误：nginx: [emerg] unknown "server" variable

这是我的 prod.conf 文件：

server {
    listen 80;
    location / {
        proxy_pass          http://users:5000;
        proxy_redirect      default;
        proxy_set_header    Host $host;
        proxy_set_header    X-Real-IP $remote_addr;
        proxy_set_header    X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header    X-Forwarded-Host $server-name;
    }
}

这是在 Dockerfile-prod 文件中：

FROM nginx:1.15.8-alpine
RUN rm /etc/nginx/conf.d/default.conf
COPY /prod.conf /etc/nginx/conf.d

compose-prod.yml 文件：

version: '3.7'
services:
  users:
    build:
    context: ./services/users
    dockerfile: Dockerfile-prod
  expose:
    - '5000'
  environment:
    - FLASK_ENV=production
    - APP_SETTINGS=project.config.ProductionConfig
    - DATABASE_URL=postgres://postgres:postgres@users-db:5432/users_prod
    - DATABASE_TEST_URL=postgres://postgres:postgres@users-db:5432/users_test
  depends_on:
    - users-db
users-db:
  build:
    context: ./services/users/project/db
    dockerfile: Dockerfile
  expose:
    - '5432'
  environment:
    - POSTGRES_USER=postgres
    - POSTGRES_PASSWORD=postgres
nginx:
  build:
    context: ./services/nginx
    dockerfile: Dockerfile-prod
  restart: always
  ports:
    - 80:80
  depends_on:
    - users

为什么给我这个错误？

您应该使用带下划线的$server_name而不是$server-name http://nginx.org/en/docs/http/ngx_http_core_module.html#server_name
