Hostinger共享主机部署Symfony 6：.htaccess重定向public目录失败求助

我在Hostinger共享主机上部署Symfony 6应用，主机根目录是public_html，服务商告知无法手动修改根目录，需通过配置.htaccess将请求重定向至public目录，但配置后并未生效，域名dijeesco.com.co无法正常访问。

public_html目录下的.htaccess原内容 #

#RewriteCond %{REQUEST_URI} !^/public/
#RewriteRule ^(.*)$ /public/$1 [L]

<IfModule mod_rewrite.c >
    RewriteEngine on
    RewriteOptions inherit

    # SSL and let's encrypt
    RewriteCond %{REQUEST_URI} !^/\.well-known/acme-challenge/.+$
    RewriteCond %{REQUEST_URI} !^/\.well-known/pki-validation/[A-F0-9]{32}\.txt(?:\ Comodo\ DCV)?$
    RewriteRule ^.well-known/acme-challenge - [L]

    # redirect to no-www
    RewriteBase /
    RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC]
    RewriteRule ^(.*)$ http://%1/$1 [R=301,L]

    # https redirect
    RewriteCond %{HTTPS} !=on
    RewriteRule .* https://%{HTTP_HOST}%{REQUEST_URI} [R=301,L]

    # redirect all requests to public directory
    RewriteCond %{REQUEST_URI} !public/
    RewriteRule (.*) /public/$1 [L]
</IfModule>

public目录下的.htaccess原内容 #

RewriteEngine On 
RewriteCond %{HTTP:X-Forwarded-Proto} !https
RewriteCond %{HTTPS} !on
RewriteRule ^(.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# Use the front controller as index file. It serves as a fallback solution when
# every other rewrite/redirect fails (e.g. in an aliased environment without
# mod_rewrite). Additionally, this reduces the matching process for the
# start page (path "/") because otherwise Apache will apply the rewriting rules
# to each configured DirectoryIndex file (e.g. index.php, index.html, index.pl).
DirectoryIndex index.php

# By default, Apache does not evaluate symbolic links if you did not enable this
# feature in your server configuration. Uncomment the following line if you
# install assets as symlinks or if you experience problems related to symlinks
# when compiling LESS/Sass/CoffeScript assets.
# Options +FollowSymlinks

# Disabling MultiViews prevents unwanted negotiation, e.g. "/index" should not resolve
# to the front controller "/index.php" but be rewritten to "/index.php/index".
<IfModule mod_negotiation.c>
    Options -MultiViews
</IfModule>

<IfModule mod_rewrite.c>
    # This Option needs to be enabled for RewriteRule, otherwise it will show an error like
    # 'Options FollowSymLinks or SymLinksIfOwnerMatch is off which implies that RewriteRule directive is forbidden'
    Options +FollowSymlinks

    RewriteEngine On

    # Determine the RewriteBase automatically and set it as environment variable.
    # If you are using Apache aliases to do mass virtual hosting or installed the
    # project in a subdirectory, the base path will be prepended to allow proper
    # resolution of the index.php file and to redirect to the correct URI. It will
    # work in environments without path prefix as well, providing a safe, one-size
    # fits all solution. But as you do not need it in this case, you can comment
    # the following 2 lines to eliminate the overhead.
    RewriteCond %{REQUEST_URI}::$0 ^(/.+)/(.*)::\2$
    RewriteRule .* - [E=BASE:%1]

    # Sets the HTTP_AUTHORIZATION header removed by Apache
    RewriteCond %{HTTP:Authorization} .+
    RewriteRule ^ - [E=HTTP_AUTHORIZATION:%0]

    # Redirect to URI without front controller to prevent duplicate content
    # (with and without `/index.php`). Only do this redirect on the initial
    # rewrite by Apache and not on subsequent cycles. Otherwise we would get an
    # endless redirect loop (request -> rewrite to front controller ->
    # redirect -> request -> ...).
    # So in case you get a "too many redirects" error or you always get redirected
    # to the start page because your Apache does not expose the REDIRECT_STATUS
    # environment variable, you have 2 choices:
    # - disable this feature by commenting the following 2 lines or
    # - use Apache >= 2.3.9 and replace all L flags by END flags and remove the
    #   following RewriteCond (best solution)
    RewriteCond %{ENV:REDIRECT_STATUS} =""
    RewriteRule ^index\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]

    # If the requested filename exists, simply serve it.
    # We only want to let Apache serve files and not directories.
    # Rewrite all other queries to the front controller.
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ %{ENV:BASE}/index.php [L]
</IfModule>

<IfModule !mod_rewrite.c>
    <IfModule mod_alias.c>
        # When mod_rewrite is not available, we instruct a temporary redirect of
        # the start page to the front controller explicitly so that the website
        # and the generated links can still be used.
        RedirectMatch 307 ^/$ /index.php/
        # RedirectTemp cannot be used instead
    </IfModule>
</IfModule>

修复方案 #

1. 优化public_html下的.htaccess #

合并规则避免冲突，确保ACME验证路径正常，统一处理HTTPS和www跳转：

<IfModule mod_rewrite.c>
    RewriteEngine On
    RewriteBase /

    # 保留ACME验证路径，不做重定向
    RewriteCond %{REQUEST_URI} ^/\.well-known/acme-challenge/ [OR]
    RewriteCond %{REQUEST_URI} ^/\.well-known/pki-validation/
    RewriteRule ^ - [L]

    # 跳转至无www的HTTPS地址
    RewriteCond %{HTTP_HOST} ^www\.(.*)$ [NC,OR]
    RewriteCond %{HTTPS} !=on
    RewriteRule ^(.*)$ https://%1/$1 [R=301,L]

    # 所有请求重定向至public目录，排除已在public下的请求
    RewriteCond %{REQUEST_URI} !^/public/
    RewriteRule ^(.*)$ public/$1 [L]
</IfModule>

去掉RewriteOptions inherit避免上层配置冲突，将绝对路径/public/$1改为相对路径public/$1适配Hostinger环境。

2. 调整public目录下的.htaccess #

删除重复的HTTPS重定向规则，防止循环跳转：

# 移除原有的HTTPS重定向规则（已在根目录统一处理）
# RewriteCond %{HTTP:X-Forwarded-Proto} !https
# RewriteCond %{HTTPS} !on
# RewriteRule ^(.*) https://%{HTTP_HOST}%{REQUEST_URI} [L,R=301]

# 保留Symfony核心配置
DirectoryIndex index.php

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

<IfModule mod_rewrite.c>
    Options +FollowSymlinks
    RewriteEngine On

    # 自动设置RewriteBase
    RewriteCond %{REQUEST_URI}::$0 ^(/.+)/(.*)::\2$
    RewriteRule .* - [E=BASE:%1]

    # 保留HTTP_AUTHORIZATION头
    RewriteCond %{HTTP:Authorization} .+
    RewriteRule ^ - [E=HTTP_AUTHORIZATION:%0]

    # 若出现循环跳转，可注释以下两行index.php重定向规则
    # RewriteCond %{ENV:REDIRECT_STATUS} =""
    # RewriteRule ^index\.php(?:/(.*)|$) %{ENV:BASE}/$1 [R=301,L]

    # 静态文件直接返回，其余请求转发至index.php
    RewriteCond %{REQUEST_FILENAME} !-f
    RewriteRule ^ %{ENV:BASE}/index.php [L]
</IfModule>

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

3. 额外检查项 #

• 确认Hostinger主机已启用mod_rewrite（共享主机默认开启，若未开启可联系客服）
• 清除浏览器缓存（301重定向会被缓存，之前的错误配置可能遗留问题）
• 修改Symfony的.env文件，设置APP_ENV=prod、APP_URL=https://dijeesco.com.co
• 运行生产环境缓存命令：composer dump-env prod和php bin/console cache:clear --env=prod
