NGINX配置问题：Symphony应用/app请求无法转发至app.php

我正在为Symphony应用配置NGINX，目标是将所有指向/app的请求转发到app.php，但配置后无法实现需求：

• 第一次配置用location /时，访问http://*.host.com/app无响应
• 修改为location /app/后，访问返回404错误
  目前应用可通过site.host.com/login/访问，后台实际路由是site.host.com/app.php/login/，需要实现site.host.com/app/login/的路由形式。

第一次配置尝试 #

server {
    listen       81;
    server_name  *.host.com;
    port_in_redirect off;

    access_log  /var/log/nginx/_access.log;
    error_log   /var/log/nginx/_error.log;

    root   /var/www/html/web;
    index index.php index.html index.htm;

    location / {
        # try to serve file directly, fallback to rewrite
        try_files $uri @rewriteapp;
    }

    location @rewriteapp {
        # rewrite all to app.php
        rewrite ^(.*)$ /app.php/$1 last;
    }

    # PHP-FPM configuration
    location ~ [^/]\.php(/|$) {
        fastcgi_split_path_info  ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php/php8.2-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param HTTP_PROXY "";
        fastcgi_param PATH_INFO       $fastcgi_path_info;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include       fastcgi_params;
    }
}

修改后的配置尝试 #

server {
    listen       81;
    server_name  *.host.com;
    port_in_redirect off;

    access_log  /var/log/nginx/_access.log;
    error_log   /var/log/nginx/_error.log;

    root   /var/www/html/web;
    index index.php index.html index.htm;

    location /app/ {
        # try to serve file directly, fallback to rewrite
        try_files $uri @rewriteapp;
    }

    location @rewriteapp {
        # rewrite all to app.php
        rewrite ^(.*)$ /app.php/$1 last;
    }

    # PHP-FPM configuration
    location ~ [^/]\.php(/|$) {
        fastcgi_split_path_info  ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php/php8.2-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param HTTP_PROXY "";
        fastcgi_param PATH_INFO       $fastcgi_path_info;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include       fastcgi_params;
    }
}

解决方案 #

问题出在路由重写规则和location匹配逻辑上，调整后的完整配置如下：

server {
    listen       81;
    server_name  *.host.com;
    port_in_redirect off;

    access_log  /var/log/nginx/_access.log;
    error_log   /var/log/nginx/_error.log;

    root   /var/www/html/web;
    index index.php index.html index.htm;

    # 同时匹配/app和/app/的请求，处理末尾斜杠问题
    location /app {
        # 先尝试访问实际文件，不存在则重写
        try_files $uri $uri/ @rewriteapp;
    }

    location @rewriteapp {
        # 重写时去除/app前缀，将剩余路径传递给app.php
        rewrite ^/app(.*)$ /app.php$1 last;
    }

    # PHP-FPM配置保持不变，确保正确解析PATH_INFO
    location ~ [^/]\.php(/|$) {
        fastcgi_split_path_info  ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php/php8.2-fpm.sock;
        fastcgi_index index.php;
        fastcgi_param HTTP_PROXY "";
        fastcgi_param PATH_INFO       $fastcgi_path_info;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        include       fastcgi_params;
    }
}

配置说明 #

• location /app：匹配所有以/app开头的请求（包括/app和/app/login/），用try_files $uri $uri/处理末尾斜杠自动跳转，避免无响应
• rewrite ^/app(.*)$ /app.php$1 last：捕获/app后的路径部分，直接重写到app.php后，比如/app/login/会被重写为/app.php/login/，和后台实际路由一致
• 保留原PHP-FPM配置，确保Symphony能正确获取PATH_INFO解析路由
