Nginx配置问题求助：/blog/可访问但子路径返回404

你的问题核心在于/blog/路径的请求转发规则配置错误，导致动态路由无法正确解析到Bludit的入口文件。以下是修正后的完整配置及关键修改说明：

关键修改点 #

• 修正try_files的 fallback 路径：原配置中/index.php?$args会指向主站根目录的index.php，应改为/blog/index.php?$args，让子路径请求正确转发到Bludit的入口文件
• 清理冗余的无效规则：删除未做任何处理的location ~ ^/bl-content/(databases|workspaces|pages|tmp)/.*$ { }规则
• 优化PHP请求的路径解析：确保SCRIPT_FILENAME正确指向Bludit目录下的PHP文件

修正后的完整Nginx配置 #

##
# This is the main Nginx configuration file.
# It should typically be located at /etc/nginx/nginx.conf
# This file includes configuration snippets from other files.
# Those files are located in /etc/nginx/conf.d/.
##

# Default server configuration
server {
    # SSL configuration
    listen [::]:443 ssl ipv6only=on; # Listen for IPv6 connections on port 443
    listen 443 ssl; # Listen for IPv4 connections on port 443
    server_name insurancepadosi.in www.insurancepadosi.in; # Your domain names

    # SSL certificate configuration
    ssl_certificate /etc/letsencrypt/live/insurancepadosi.in/fullchain.pem;
    ssl_certificate_key /etc/letsencrypt/live/insurancepadosi.in/privkey.pem;
    include /etc/letsencrypt/options-ssl-nginx.conf; # SSL configuration options
    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem; # Diffie-Hellman parameter for SSL

    # Root directory for the main website
    root /var/www/html/public;

    # Default index files
    index index.html index.htm index.nginx-debian.html index.php;

    # Main location block for handling requests to the root
    location / {
        # Try serving the requested file or directory,
        # fallback to displaying a 404 error if not found
        try_files $uri $uri.html $uri/ =404;
    }

    # Location block for serving the blog at /blog
    location /blog/ {
        alias /var/www/html/bludit/;
        index index.php;
        # 修正fallback路径，指向blog子路径的index.php
        try_files $uri $uri/ /blog/index.php?$args;

        location ~ \.php$ {
            include snippets/fastcgi-php.conf;
            # 确保SCRIPT_FILENAME正确指向alias目录下的PHP文件
            fastcgi_param SCRIPT_FILENAME $request_filename;
            fastcgi_pass unix:/var/run/php/php8.1-fpm.sock;
        }
    }

    # Bludit安全防护规则
    location ^~ /blog/bl-content/databases/ {
        deny all;
    }
    location ^~ /blog/bl-content/workspaces/ {
        deny all;
    }
    location ^~ /blog/bl-content/pages/ {
        deny all;
    }
    location ^~ /blog/bl-kernel/ {
        deny all;
    }

    # 禁止访问.htaccess文件
    location ~ /\.ht {
        deny all;
    }
}

# HTTP转HTTPS配置
server {
    listen 80 default_server; # Listen for HTTP connections on port 80
    listen [::]:80 default_server; # Listen for HTTP IPv6 connections on port 80
    server_name insurancepadosi.in www.insurancepadosi.in; # Your domain names

    # Redirect all HTTP traffic to HTTPS
    return 301 https://$host$request_uri;
}

生效步骤 #

1. 执行nginx -t验证配置语法是否正确
2. 验证通过后执行systemctl reload nginx重新加载配置
3. 确保/var/www/html/bludit目录的权限正确，Nginx进程（通常为www-data用户）需要拥有读取权限
