这看起来像是 nginx 配置问题，而不是权限问题。
如果/xxxxx是项目目录，则项目的 Web 根目录应为/xxxxx/web.
您的日志显示您正在尝试列出项目目录的内容，而您应该只访问/xxxxx/web/app_dev.php,/xxxxx/web/app.php或/xxxxx/web/config.php，
所以这个 403 错误是预期的行为。
尝试访问开发环境时，您的 URL 应该类似于
http://localhost/xxxxx/web/app_dev.php，
或者http://xxxxx.local/app_dev.php如果您的网络主机配置正确。
symfony 文档有一个 2.8 的 nginx 配置示例：
https ://symfony.com/doc/2.8/setup/web_server_configuration.html#nginx
我对其进行了一些更改以适合您的情况：
server {
server_name xxxxx.local;
root /var/www/html/xxxxx/web;
location / {
# try to serve file directly, fallback to app.php
try_files $uri /app.php$is_args$args;
}
# DEV
# This rule should only be placed on your development environment
# In production, don't include this and don't deploy app_dev.php or config.php
location ~ ^/(app_dev|config)\.php(/|$) {
fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
# When you are using symlinks to link the document root to the
# current version of your application, you should pass the real
# application path instead of the path to the symlink to PHP
# FPM.
# Otherwise, PHP's OPcache may not properly detect changes to
# your PHP files (see https://github.com/zendtech/ZendOptimizerPlus/issues/126
# for more information).
fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $realpath_root;
}
# PROD
location ~ ^/app\.php(/|$) {
fastcgi_pass unix:/var/run/php/php7.1-fpm.sock;
fastcgi_split_path_info ^(.+\.php)(/.*)$;
include fastcgi_params;
# When you are using symlinks to link the document root to the
# current version of your application, you should pass the real
# application path instead of the path to the symlink to PHP
# FPM.
# Otherwise, PHP's OPcache may not properly detect changes to
# your PHP files (see https://github.com/zendtech/ZendOptimizerPlus/issues/126
# for more information).
fastcgi_param SCRIPT_FILENAME $realpath_root$fastcgi_script_name;
fastcgi_param DOCUMENT_ROOT $realpath_root;
# Prevents URIs that include the front controller. This will 404:
# http://domain.tld/app.php/some-path
# Remove the internal directive to allow URIs like this
internal;
}
# return 404 for all other php files not matching the front controller
# this prevents access to other php files you don't want to be accessible.
location ~ \.php$ {
return 404;
}
error_log /var/log/nginx/xxxxx_error.log;
access_log /var/log/nginx/xxxxx_access.log;
}
这将进入您的 nginx 配置文件，例如：
/etc/nginx/conf.d/xxxxx.conf
然后您需要将主机名添加xxxxx.local到您的/etc/hosts文件中：
127.0.0.1 xxxxx.local
