Spring Boot 和单实例 AWS Beanstalk SSL 设置错误

Question

我在单实例 AWS Beanstalk 上设置了与 SSL 和 HTTPS（在 64 位 Amazon Linux 2/3.1.0 上运行的 Corretto 11 上的 Certbot 和 LetsEncrypt）相关的问题。 此环境用于暂存环境，稍后我将使用负载均衡器设置真实环境。

我按照下面的教程https://medium.com/@phil_mldtsv/configuring-your-aws-elastic-beanstalk-single-instance-spring-boot-app-for-https-using-lets-9750c03a8860

这是我的错误：

截至目前 (https://docs.aws.amazon.com/elasticbeanstalk/latest/dg/https-singleinstance-java.html) 的所有当前 AWS 文档都适用于 corretto java 8 Linux 1 平台。此外，您提到的 .config 文件也适用于旧平台。

对于 Corretto Java 11 Linux 2 平台，由于它是不同的平台，您需要不同的配置文件。

现在，您需要添加 .ebextensions 文件夹以及另一个名为 .platform 的文件夹

在 .ebextensions 文件夹中，您需要添加两个 .config 文件 - 一个用于安装 certbot 和生成证书，另一个用于创建 cron 作业以更新证书。第二步是可选的，但是由于 Letsencrypt 证书在 3 个月后到期，因此更新证书以使 https 继续工作至关重要。

在 .platform 中，创建此文件夹结构 nginx/conf.d。 在 conf.d 文件夹中，创建一个名为 https.conf 的文件。

现在，如果您想从 HTTP 重定向到 HTTPS，那么您需要在 conf.d/elasticbeanstalk 文件夹中添加一个名为 00_application.conf 的配置文件。请注意，名称 00_application.conf 非常重要，因为 Nginx 文件夹中已经有一个具有该名称的文件，我们将用新文件替换该文件内容，以将流量从 HTTP 重定向到 HTTPS。如果您提供其他名称，则它将不起作用。

项目结构：

root
  - .ebextensions
      - https-instance.config
      - renew-ssl.config
  - .platform
      - nginx
          - conf.d
              - elasticbeanstalk
                 - 00_application.conf
              - https.conf
  - Procfile
  - Application Jar

https-instance.config

packages:
  rpm:
    epel: https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

commands:
  01_install_certbot_packages:
    command: sudo yum -y install certbot-nginx
  02_generate_ssl:
    command: sudo certbot certonly --nginx -d ${enter_your_domain_name} --non-interactive --email ${enter_your_email_here}@gmail.com  --agree-tos

renew-ssl.config（此命令在每周一凌晨 3:30 更新证书）

files:
  /etc/cron.d/renewssl:
    content: |
      30 3 * * 1 root /usr/bin/certbot renew --quit

00_application.conf

location / {
     set $redirect 0;
     if ($http_x_forwarded_proto != "https") {
       set $redirect 1;
     }
     if ($http_user_agent ~* "ELB-HealthChecker") {
       set $redirect 0;
     }
     if ($redirect = 1) {
       return 301 https://$host$request_uri;
     }

     proxy_pass          http://127.0.0.1:5000;
     proxy_http_version  1.1;

     proxy_set_header    Connection          $connection_upgrade;
     proxy_set_header    Upgrade             $http_upgrade;
     proxy_set_header    Host                $host;
     proxy_set_header    X-Real-IP           $remote_addr;
     proxy_set_header    X-Forwarded-For     $proxy_add_x_forwarded_for;
}

https.conf

# HTTPS server

server {
    listen       443;
    server_name  localhost;

    ssl                  on;
    ssl_certificate      /etc/letsencrypt/live/${enter_your_domain_name}/fullchain.pem;
    ssl_certificate_key  /etc/letsencrypt/live/${enter_your_domain_name}/privkey.pem;

    ssl_session_timeout  5m;

    ssl_protocols  TLSv1 TLSv1.1 TLSv1.2;
    ssl_prefer_server_ciphers   on;

    location / {
        proxy_pass  http://localhost:5000;
        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;
        proxy_set_header        X-Forwarded-Proto https;
    }
}

过程文件

web: java -jar ${application_jar_name}.jar

最后，将所有 conf 文件夹连同 jar 一起压缩，并将压缩后的文件夹上传到 aws。

PS：我在这里假设默认端口为 5000。如果您通过环境变量更改它，那么您需要在配置文件中更改端口值。

Answer 2

由于与最新版本的 Amazon LInux 2/4.10 的兼容性问题，Certbot 出错。 没什么可做的，你需要自己设置手动负载均衡器，并在那里设置ssl证书。
