我在 CentOS 上工作。

我已经按照教程学习了:

• http://symfony.com/doc/current/best_practices/creating-the-project.html

• https://symfony.com/doc/current/page_creation.html

当我使用 Apache 时，我也关注了这个页面:

• https://symfony.com/doc/current/setup/web_server_configuration.html

我做了一个默认 Controller 和一个默认模板。使用此 Controller (/)，我得到以下错误(在调试工具栏中):

An error occurred while loading the web debug toolbar. Open the web profiler.

当我点击链接:“Open the web profiler”时，我可以看到 Apache 响应:

Not Found
The requested URL /_profiler/177403 was not found on this server.

在 chrome 检查器中，我可以看到: 获取 http://172.31.18.7/_wdt/177403 404(未找到)

这是我的 composer.json 中有趣的部分:

    "require": {
        "php": "^7.1.3",
        "ext-iconv": "*",
        "doctrine/doctrine-fixtures-bundle": "^3.0",
        "sensio/framework-extra-bundle": "^5.1",
        "sonata-project/admin-bundle": "^3.35",
        "sonata-project/doctrine-orm-admin-bundle": "^3.6",
        "symfony/apache-pack": "^1.0",
        "symfony/console": "^4.0",
        "symfony/flex": "^1.0",

    },

        "symfony/dotenv": "^4.0",
        "symfony/web-profiler-bundle": "^4.0"
    },

我的 httpd.conf :

<VirtualHost *:80>
DocumentRoot /var/www/html/elora/public
ServerName eloradev
ServerAlias www.elora.dev
DirectoryIndex index.php

<Directory "elora/public">
    AllowOverride all
    Order Allow,Deny
    Deny from all
    Allow from 127.0.0.1
    Allow from ::1
    Allow from localhost
</Directory>

<Directory elora>
    Options FollowSymlinks
</Directory>    

ErrorLog /var/apache/logs/error.log
CustomLog /var/apache/logs/access.log combined  

</VirtualHost>

还有我的 .htaccess :

DirectoryIndex index.php

<IfModule mod_negotiation.c>
    Options -MultiViews
</IfModule>

<IfModule mod_rewrite.c>
    RewriteEngine On

    RewriteCond %{REQUEST_URI}::$1 ^(/.+)/(.*)::\2$
    RewriteRule ^(.*) - [E=BASE:%1]

    RewriteCond %{HTTP:Authorization} .
    RewriteRule ^ - [E=HTTP_AUTHORIZATION:%{HTTP:Authorization}]

    RewriteCond %{ENV:REDIRECT_STATUS} ^$
    RewriteRule ^index\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]

    RewriteCond %{REQUEST_FILENAME} -f
    RewriteRule ^ - [L]

    RewriteRule ^ %{ENV:BASE}/index.php [L]
</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        RedirectMatch 307 ^/$ /index.php/
    </IfModule>
</IfModule>

最后，我的/lucky/number ( https://symfony.com/doc/current/page_creation.html ) 引发了 apache 消息:

Not Found
The requested URL /lucky/number was not found on this server.

看起来路由组件不起作用。

路由器规则(调试:路由器):

 -------------------------- -------- -------- ------ -----------------------

我已经手动创建了目录/_wdt，以防万一，但它并没有改变任何东西。

我已经用 debug:event-dispatcher 检查了错误，没什么特别的。

我注意到探查器的缓存位于该目录中:var/cache/dev/profiler/03/74/并命名为 177403

还有一件事，我用“root”用户运行了 composer。而且我已经使用 chown 更改了我的项目的所有者。

这是我的文件 .env 的一部分:

###> symfony/framework-bundle ###
APP_ENV=dev

最佳答案

我认为这需要 htaccess 或 mod_rewrite

composer require symfony/apache-pack
