在vps中部署rails 7和nginx

Question

我有一个包含 importmap、scss、rails 7 和 nginx 的 Rails 项目。

我使用 digital ocean 上的 vps 来通过 docker 和 nginx 进行部署。

我的 Rails 代码留在这里 https://github.com/TryTech/try_tech

和我的 nginx.conf

worker_processes auto;
worker_rlimit_nofile 500000;
pcre_jit on;

error_log /var/log/nginx/error.log warn;

events {
use epoll;
worker_connections 1024;
}

http {
include /etc/nginx/mime.types;
access_log off;
error_log /dev/null emerg;

    ssl_session_cache shared:SSL:10m; 
    ssl_session_timeout 10m; 
    
    upstream web {
        server localhost:3000;
        server localhost:3001;
        keepalive 500;
    }
    
    server {
        listen 443 ssl;
        server_name trytech.app;
    
        ssl_certificate  /var/www/certbot/live/trytech.app/fullchain.pem;
        ssl_certificate_key /var/www/certbot/live/trytech.app/privkey.pem;
    
        location / {
            proxy_buffering off;
            proxy_set_header Connection "";
            proxy_http_version 1.1;
            proxy_set_header Keep-Alive "";
            proxy_set_header Proxy-Connection "keep-alive";
            proxy_pass http://web;
        }
    
        location ~ ^/assets/ {
            expires 1y;
            add_header Cache-Control public;
    
            add_header ETag "";
        }

}
}

我使用 docker-compose 来启动容器。

docker-compose：

version: '3.8'

services:
  certbot:
    image: certbot/certbot:latest
    volumes:
      - ./certbot/www/:/var/www/certbot/:rw

      - postgres_data:/var/lib/postgresql/data
    env_file:
      - ./.env.prod
    healthcheck:
      test: [ "CMD-SHELL", "pg_isready" ]
      interval: 5s
      timeout: 5s
      retries: 20
      start_period: 10s
    deploy:
      resources:
        limits:
          cpus: '0.35'
          memory: '1.3GB'

volumes:

我认为如果您需要更多信息，这已经足够了。简而言之，我的问题归结为无法使用来自服务器的 javascript 和 css。

我已经尝试过几种实现方式，例如让rails处理资产或仅让nginx处理，但我还没有成功，我对这两种技术都不是很有经验，这是我的第一个项目。如果您想在生产环境中调试浏览器，请使用以下 url。 https://trytech.app/

提前感谢您的宝贵时间

期望网站能够正确使用 javascript 和 css。

您的问题与部署无关。首先在本地修复您的应用程序。

手动添加引导引脚以从 jspm 加载：

# config/importmap.rb

pin "bootstrap", to: "https://ga.jspm.io/npm:[email protected]/dist/js/bootstrap.esm.js"
pin "@popperjs/core", to: "https://ga.jspm.io/npm:@popperjs/[email protected]/lib/index.js"

暂时将

importmap-rails

降级为

v1

：

# Gemfile 

gem "importmap-rails", "~> 1.0"

由于此更改，

importmap-rails

v2

目前很多时候无法使用：
