使用多個 wordpress 站點配置 nginx 多個子文件夾時出錯

我在為多個子文件夾配置 nginx 時遇到問題，我在 serverfault 上應用了許多解決方案，但它不適用於我的網站。我的網站使用兩個 wordpress。主站https://optshare.com>和部落格站：<https://optshare.com/blog

我在根文件夾 /var/www/html/blog 中創建了一個子文件夾 blog

這是我的 nginx 配置

主站點正在執行，但部落格站點無法執行

我會設置一個反向代理並通過它為兩個 WordPress 網站提供服務。此設置的邏輯是：

• 在您的主 vhost 文件（這將是反向代理）中，將伺服器設置為使用 server_name optopshare.com 在公共 IP 上列出。
• 在其中添加 http->https 重定向和 SSL 處理（因為您已經這樣做了）。
• 添加兩個位置部分

location / {
   proxy_set_header X-Original-Request $request_uri;
   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 $scheme;
   proxy_pass http:127.0.0.1:8001;
}
location /blog/ {
   proxy_set_header X-Original-Request $request_uri;
   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 $scheme;
   proxy_pass http:127.0.0.1:8002;
}

• 這就是主要的 vhost 文件。
• 使用偵聽 127.0.0.1:8001 的伺服器創建第二個 vhost 文件，以服務於 WordPress 主站點。
• 使用偵聽 127.0.0.1:8002 的伺服器創建第三個 vhost 文件，用於為 /blog WordPress 站點提供服務。

請記住，如果在反向代理後面提供 WordPress，則需要注意一些事項，具體取決於您的個人設置。例如：

• 要讓 WordPress 在反向代理後使用 SSL 執行，您需要將其添加到 wp-config.file：

if (isset($_SERVER['HTTP_X_FORWARDED_PROTO']) && $_SERVER['HTTP_X_FORWARDED_PROTO'] == 'https') {
   $_SERVER['HTTPS']='on';
}
