将 Elastic Beanstalk URL 重定向到域名

the*_*est 5 apache dns amazon-web-services amazon-route53 amazon-elastic-beanstalk

我有一个托管在 AWS Elastic Beanstalk 上的应用程序,它被分配了一个环境 URL,如下所示:

<my-appname>.<aws-region>.elasticbeanstalk.com

我还注册了一个域名,如下:

my-appname.com

在 AWS Route 53 中,我指出了A ALIASEBmy-appname.com环境:

my-appname.com>A ALIAS <my-appname>.<aws-region>.elasticbeanstalk.com

我通过我的注册商设置了 Route 53 域名服务器,以通过 Amazon 管理 DNS。

一切正常

我想了解如何确保对<my-appname>.<aws-region>.elasticbeanstalk.com>域的任何请求都到达301my-appname.com

我当前使用 ApacheRewriteRule将所有非 www 请求重定向到网站的 www 版本,在文件中使用以下内容.config

<If "'%{HTTP_HOST}' !~ /^www\./">
    RewriteRule ^(.*)$ http://www.%{HTTP_HOST}%{REQUEST_URI} [R=301,L]
</If>

HTTP_HOST简单地更改为是一个好的做法吗my-appname.com

编辑:无论如何,这种方法似乎不起作用。不知道为什么?

使用 Elastic Beanstalk (Amazon Linux 2) 和 Nginx 时,您有两种解决方案:

扩展 Elastic Beanstalk 默认 nginx.conf

.platform/nginx/conf.d/redirections.conf创建一个在源代码中命名的文件,其中包含:

server {
    server_name .elasticbeanstalk.com;
    return 301 https://example.com$request_uri;
}

Nginx 文档:https://www.nginx.com/blog/creating-nginx-rewrite-rules/

(example.com 是您自己的域名)

创建您自己的 nginx.conf 以替换 Elastic Beanstalk 中的默认配置

  • /etc/nginx/nginx.conf使用 SSH 连接到 Elastic Beanstalk EC2 实例,复制原始内容(*)
  • 创建一个在源代码中命名的文件.platform/nginx/nginx.conf并粘贴内容
  • 根据您的需要修改它并添加:
server {
    server_name .elasticbeanstalk.com;
    return 301 https://example.com$request_uri;
}

您最终应该得到/etc/nginx/nginx.conf如下所示的结果(截至 2022 年 5 月 8 日取自 Amazon Linux 2):

有关 Nginx 配置的更多信息

同时,我还建议对 Nginx 配置进行其他修改。

将 www 重定向到 root

将www.example.com重定向到 example.com 的示例。

# .platform/nginx/conf.d/redirections.conf

# /sf/answers/3016277701/
# https://tribulant.com/docs/hosting-domains/hosting/9867/redirecting-to-www-or-non-www/
# This can be done at the load balancer level but I prefer to do it here
# Test this with `curl --head https://www.example.com` and `curl --head http://www.example.com`
server {
    server_name www.example.com;
    return 301 https://example.com$request_uri;
}

先决条件:

HTTP 安全标头

为了安全起见,我建议设置这些 HTTP 标头:

# .platform/nginx/conf.d/security_headers.conf

# Remove Nginx version in error page and header
server_tokens off;

# Security headers thanks to https://observatory.mozilla.org/ and https://webpagetest.org/
# Inspired by https://www.mozilla.org/ HTTP headers
# https://gist.github.com/plentz/6737338
# https://github.com/GetPageSpeed/ngx_security_headers
add_header Content-Security-Policy "default-src 'self';
add_header Strict-Transport-Security "max-age=31536000; includeSubDomains; preload";
add_header X-Content-Type-Options nosniff;
add_header X-Frame-Options DENY;
add_header X-XSS-Protection "1; mode=block";

文件压缩(.js、.css、.html...)

您可以使用 启用压缩gzip on;。不幸的是,您无法扩展默认的 nginx.conf 来启用压缩。您必须复制粘贴并修改原始的 nginx.conf ( .platform/nginx/nginx.conf)。

注意:您可以拥有自己的文件.platform/nginx/nginx.conf并仍然使用.platform/nginx/conf.d/目录中的文件。

将 HTTP 重定向到 HTTPS

2 解决方案:使用负载均衡器(Application Load Balancer)或者自定义.platform/nginx/nginx.conf

# .platform/nginx/nginx.conf

...

    server {
        listen        80 default_server;

        ...

我目前的理解是最好的方法是使用服务器级重写来解决该问题。示例(对于 Apache 服务器)如​​下:

Rewrite Engine On

# Catch requests to domains other than your primary (custom) domain
Rewrite Cond %{HTTP_HOST} !~ appname.tld

# Send those requests to the primary domain
RewriteRule (.*) http://www.appname.tld%{REQUEST_URI} [R=301, L]
