使用 SSL 在 nginx 反向代理后面的 Docker 上的 Wordpress

Question

这是我的问题，

我需要在子目录 url ("https://test.com/blog/") 上安装 wordpress 应用程序。 由于我的整个环境都在 Docker 上运行，我决定对 wordpress 应用程序做同样的事情。

为了尽可能简单地启动它，我将 wordpress 图像添加到我的 docker-compose.yml 中，并在应用程序上创建了一个子域（“http://blog.test.com”，它没有使用 https）使用我的 nginx 反向代理。

效果很好，我就这样安装了我的 wordpress。

现在我正在尝试将此迁移到我最初的需求，我的问题是一切正常，除非我无法访问管理网址 (https://test.com/blog/admin)，因为它会在 https://test.com/blog/wp-admin 上保持重定向，而我收到“重定向过多”错误。

这是我的 nginx 配置：

server {
  listen 80 default_server;
  listen [::]:80 default_server;
  server_name test.com;
  return 301 https://$server_name$request_uri;
}

server {
    listen 443 ssl default_server;
    listen [::]:443 ssl default_server;
    server_name test.com;

    error_log /var/log/nginx/test_error.log;
    access_log /var/log/nginx/test_access.log;

    location /blog/ {
        auth_basic "Restricted";
        auth_basic_user_file /etc/nginx/test-htpasswd;
        proxy_pass http://127.0.0.1:8090;
        proxy_http_version 1.1;
        proxy_buffering off;
        proxy_read_timeout    90;
        proxy_connect_timeout 90;
        proxy_redirect        off;
        proxy_set_header Host $host;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header Connection $proxy_connection;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Ssl $proxy_x_forwarded_ssl;
        proxy_set_header X-Forwarded-Port 443;

    # Mitigate httpoxy attack (see README for details)
           proxy_set_header Proxy "";
    }

    location / {
        auth_basic "Restricted";
        auth_basic_user_file /etc/nginx/test-htpasswd;
        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_pass http://127.0.0.1:8082;
    }

    ssl_certificate /etc/letsencrypt/live/test.com/fullchain.pem; # managed by Certbot
    ssl_certificate_key /etc/letsencrypt/live/test.com/privkey.pem; # managed by Certbot

    add_header X-Robots-Tag "noindex, nofollow, nosnippet, noarchive";
}

我还在 wordpress 容器中 wp-config.php 文件的顶部添加了以下内容：

define('FORCE_SSL_ADMIN', true);

if($_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https'){

    $_SERVER['HTTPS'] = 'on';
    $_SERVER['SERVER_PORT'] = 443;
}

define('WP_HOME','https://test.com/blog/');
define('WP_SITEURL','https://test.com/blog/');

我注意到的是，如果我尝试通过以下方式打印 $_SERVER 变量

var_dump($_SERVER);

在 wp-config.php 中，没有任何 nginx 代理变量。

这是输出：

你有什么想法吗？

其实我找到了办法！ 我的 nginx 配置出错，如果有人感兴趣，这是我的最终工作配置：

nginx.conf 文件（wordpress 块）：

location /blog/ {
        proxy_pass http://127.0.0.1:8093/;
        proxy_http_version 1.1;
        proxy_buffering off;
        proxy_read_timeout    90;
        proxy_connect_timeout 90;
        proxy_redirect        off;
        proxy_set_header Host $host;
        proxy_set_header Upgrade $http_upgrade;
        proxy_set_header X-Real-IP $remote_addr;
        proxy_set_header X-Forwarded-Proto https;
        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
        proxy_set_header X-Forwarded-Port 443;
        proxy_set_header Proxy "";
    }

这是我在 wordpress 容器的 wp_config.php 文件顶部添加的内容：

define('FORCE_SSL_ADMIN', true);

$_SERVER['REQUEST_URI'] = str_replace("/wp-admin/", "/blog/wp-admin/",  $_SERVER['REQUEST_URI']);

if($_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https'){

    $_SERVER['HTTPS'] = 'on';
    $_SERVER['SERVER_PORT'] = 443;
}

define('WP_HOME','https://test.com/blog/');
define('WP_SITEURL','https://test.com/blog/');

干杯！
