我已经自己配置了Apache，并尝试在虚拟主机上加载phpMyAdmin，但收到了以下信息：

403禁止访问您没有访问此服务器上的权限

我的httpd.conf

#
# This is the main Apache HTTP server configuration file.  It contains the
# configuration directives that give the server its instructions.
# See <URL:http://httpd.apache.org/docs/2.2> for detailed information.
# In particular, see 
# <URL:http://httpd.apache.org/docs/2.2/mod/directives.html>
# for a discussion of each configuration directive.
#
# Do NOT simply read the instructions in here without understanding
# what they do.  They're here only as hints or reminders.  If you are unsure
# consult the online docs. You have been warned.  
#
# Configuration and logfile names: If the filenames you specify for many
# of the server's control files begin with "/" (or "drive:/" for Win32), the
# server will use that explicit path.  If the filenames do *not* begin
# with "/", the value of ServerRoot is prepended -- so "logs/foo.log"
# with ServerRoot set to "C:/Program Files (x86)/Apache Software Foundation/Apache2.2" will be interpreted by the
# server as "C:/Program Files (x86)/Apache Software Foundation/Apache2.2/logs/foo.log".
#
# NOTE: Where filenames are specified, you must use forward slashes
# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").
# If a drive letter is omitted, the drive on which httpd.exe is located
# will be used by default.  It is recommended that you always supply
# an explicit drive letter in absolute paths to avoid confusion.

#
# ServerRoot: The top of the directory tree under which the server's
# configuration, error, and log files are kept.
#
# Do not add a slash at the end of the directory path.  If you point
# ServerRoot at a non-local disk, be sure to point the LockFile directive
# at a local disk.  If you wish to share the same ServerRoot for multiple
# httpd daemons, you will need to change at least LockFile and PidFile.
#
ServerRoot "C:/Program Files (x86)/Apache Software Foundation/Apache2.2"

#
# Listen: Allows you to bind Apache to specific IP addresses and/or
# ports, instead of the default. See also the <VirtualHost>
# directive.
#
# Change this to Listen on specific IP addresses as shown below to 
# prevent Apache from glomming onto all bound IP addresses.
#
#Listen 12.34.56.78:80
Listen 127.0.0.1:80

2016年10月更新

4年前，由于该答案被许多人用作参考，并且这些年来我从安全性角度学到了很多东西，所以我觉得我有责任澄清一些重要说明，并相应地更新了我的答案。

原始答案是正确的，但对于某些生产环境而言并不安全，此外，我还要解释一些在设置环境时可能会遇到的问题。

如果您正在寻找一种快速的解决方案，而“安全性不重要”，即开发环境，请跳过并阅读原始答案

许多情况下可能导致403 Forbidden：

A.目录索引（来自mod_autoindex.c）

当你访问一个目录，有此目录中没有发现默认的文件 和阿帕奇Options Indexes不在此目录已启用。

A.1。DirectoryIndex选项示例

DirectoryIndex index.html default.php welcome.php

A2。Options Indexes选项

如果设置，则apache将列出目录内容（如果未找到默认文件）（来自上述👆🏻选项）

如果以上条件都不满足

您将收到403 Forbidden

推荐建议

• 除非确实需要，否则您不应允许目录列表。
• 将默认索引限制DirectoryIndex为最小值。
• 如果要修改，则仅将修改限制在所需的目录中，例如，使用.htaccess文件或将修改内容放入<Directory /my/directory>指令中

B. deny,allow指令（Apache 2.2）

@Radu在评论中提到了@Simon A. Eugster 您的请求被这些指令拒绝，列入黑名单或列入白名单。

我不会发表完整的解释，但是我认为一些示例可以帮助您理解，简而言之，请记住以下规则：

如果两者都被匹配，那么最后一个指令将是一个获胜者

Order allow,deny

如果两个指令都匹配，则拒绝将获胜（即使在conf中的allow指令之后编写了指令deny）

Order deny,allow

如果两个指令都匹配，allow将获胜

例子1

Order allow,deny
Allow from localhost mydomain.com

只有localhost和* .mydomain.com可以访问此主机，所有其他主机均被拒绝

例子2

Order allow,deny
Deny from evil.com
Allow from safe.evil.com # <-- has no effect since this will be evaluated first

所有请求均被拒绝，最后一行可能会欺骗您，但请记住，如果同时符合最后一条获胜规则（此处，“拒绝”为最后一条），则与以下内容相同：

Order allow,deny
Allow from safe.evil.com
Deny from evil.com # <-- will override the previous one 

例子4

Order deny,allow
Allow from site.com
Deny from untrusted.site.com # <-- has no effect since this will be matched by the above `Allow` directive

接受所有主机的请求

示例4：典型的公共网站（除非已列入黑名单，否则允许）

Order allow,deny
Allow from all
Deny from hacker1.com
Deny from hacker2.com

示例5：典型的Intranet和安全站点（除非列入白名单，否则拒绝）

Order deny,allow
Deny from all
Allow from mypc.localdomain
Allow from managment.localdomain

C. Require指令（Apache 2.4）

Apache 2.4使用了一个名为 mod_authz_host

Require all granted =>允许所有请求

Require all denied =>拒绝所有请求

Require host safe.com =>仅允许来自safe.com

D.文件权限

大多数人做错的一件事是配置文件权限，

黄金法则是

无需许可即可开始，并根据需要添加

在Linux中：

• 目录应获得Execute许可

• 文件应具有Read权限

• 是的，您是对的，请勿添加Execute文件权限

例如，我使用此脚本来设置文件夹权限

# setting permissions for /var/www/mysite.com

# read permission ONLY for the owner 
chmod -R /var/www/mysite.com 400 

# add execute for folders only
find /var/www/mysite.com -type d -exec chmod -R u+x {} \;

# allow file uploads 
chmod -R /var/www/mysite.com/public/uploads u+w

# allow log writing to this folder
chmod -R /var/www/mysite.com/logs/ 

我以此代码为例，在其他情况下设置可能会有所不同

原始答案

我遇到了同样的问题，但是我通过在httpd.conf的全局目录设置或httpd-vhosts.conf的特定目录块中设置options指令解决了该问题：

Options Indexes FollowSymLinks Includes ExecCGI

默认情况下，您的全局目录设置为(httpd.conf line ~188)：

<Directory />
    Options FollowSymLinks
    AllowOverride All
    Order deny,allow
    Allow from all
</Directory>

将选项设置为： Options Indexes FollowSymLinks Includes ExecCGI

最后，它看起来应该像：

<Directory />
    #Options FollowSymLinks
    Options Indexes FollowSymLinks Includes ExecCGI
    AllowOverride All
    Order deny,allow
    Allow from all
</Directory>

也可以尝试改变Order deny,allow，并Allow from all通过线Require all granted。

附录

目录索引源代码（为简洁起见，删除了一些代码）

if (allow_opts & OPT_INDEXES) {
     return index_directory(r, d);
} else {
        const char *index_names = apr_table_get(r->notes, "dir-index-names");

        ap_log_rerror(APLOG_MARK, APLOG_ERR, 0, r, APLOGNO(01276)
                      "Cannot serve directory %s: No matching DirectoryIndex (%s) found, and "
                      "server-generated directory index forbidden by "
                      "Options directive",
                       r->filename,
                       index_names ? index_names : "none");
        return HTTP_FORBIDDEN;
    }

我知道此问题已解决，但我碰巧自己解决了同一问题。

的原因

禁止您无权访问此服务器上的/

实际上是中的apache目录的默认配置httpd.conf。

#
# Each directory to which Apache has access can be configured with respect
# to which services and features are allowed and/or disabled in that
# directory (and its subdirectories). 
#
# First, we configure the "default" to be a very restrictive set of 
# features.  
#
<Directory "/">
    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    Deny from all          # the cause of permission denied
</Directory>

只需更改Deny from all为即可Allow from all解决许可问题。

或者，更好的方法是在virtualhost配置上指定各个目录权限。

<VirtualHost *:80>
    ....

    # Set access permission
    <Directory "/path/to/docroot">
        Allow from all
    </Directory>

    ....
</VirtualHost>

从Apache-2.4开始，访问控制是使用新模块完成的mod_authz_host（从2.2升级到2.4）。因此，Require应使用新指令。

<VirtualHost *:80>
    ....

    # Set access permission
    <Directory "/path/to/docroot">
        Require all granted
    </Directory>

    ....
</VirtualHost>

在默认的/ var / www /之外托管的目录的一个常见问题是，Apache用户不仅需要对托管站点的目录和子目录的权限。Apache要求对所有目录的权限一直到托管站点的文件系统的根目录为止。Apache在安装后会自动获得分配给/ var / www /的权限，因此，如果您的主机目录位于该目录的正下方，则该目录不适用于您。编辑：Daybreaker报告他的Apache已安装，没有对默认目录的正确访问权限。

例如，您有一台开发机，您的站点目录为：

/username/home/Dropbox/myamazingsite/

您可能认为您可以摆脱：

chgrp -R www-data /username/home/Dropbox/myamazingsite/
chmod -R 2750 /username/home/Dropbox/myamazingsite/

因为这赋予了Apache访问您网站目录的权限？嗯，这是正确的，但还不够。Apache一直在目录树中需要权限，因此您需要执行以下操作：

chgrp -R www-data /username/
chmod -R 2750 /username/

显然，我不建议您在不分析该目录结构中的内容的情况下，将访问生产服务器上的Apache的权限授予完整的目录结构。对于生产，最好保留默认目录或仅用于保存Web资产的其他目录结构。

Edit2：正如u / chimeraha指出的那样，如果不确定权限的用途，最好将站点目录移出主目录，以避免潜在地将自己锁定在主目录之外。

Apache 2.4中的某些配置参数已更改。设置Zend Framework 2应用程序时，我遇到了类似的问题。经过研究，以下是解决方案：

配置错误

<VirtualHost *:80>
    ServerName zf2-tutorial.localhost
    DocumentRoot /path/to/zf2-tutorial/public
    SetEnv APPLICATION_ENV "development"
    <Directory /path/to/zf2-tutorial/public>
        DirectoryIndex index.php
        AllowOverride All
        Order allow,deny #<-- 2.2 config
        Allow from all #<-- 2.2 config
    </Directory>
</VirtualHost>

正确配置

<VirtualHost *:80>
    ServerName zf2-tutorial.localhost
    DocumentRoot /path/to/zf2-tutorial/public
    SetEnv APPLICATION_ENV "development"
    <Directory /path/to/zf2-tutorial/public>
        DirectoryIndex index.php
        AllowOverride All
        Require all granted #<-- 2.4 New configuration
    </Directory>
</VirtualHost>

如果您打算从Apache 2.2迁移到2.4，请参考：http : //httpd.apache.org/docs/2.4/upgrading.html

使用Apache 2.2

Order Deny,Allow
Allow from all

使用Apache 2.4

Require all granted

来自http://httpd.apache.org/docs/2.4/en/upgrading.html

在使用Apache 2.4的Ubuntu 14.04上，我执行了以下操作：

在文件apache2.conf中（在下方/etc/apache2）添加以下内容：

<Directory /home/rocky/code/documentroot/>
  Options Indexes FollowSymLinks
  AllowOverride None
  Require all granted
</Directory>

并重新加载服务器：

sudo service apache2 reload

编辑：这也可以在OS X Yosemite和Apache 2.4上使用。最重要的行是

要求所有授予

如果您使用的是WAMP服务器，请尝试以下操作：

• 单击任务栏上的WAMP服务器图标

• 选择在线选项

• 您的服务器将自动重启

• 然后尝试访问您的本地网站

如果将CentOS与SELinux一起使用，请尝试：

sudo restorecon -r /var/www/html

我通过将用户添加到来解决了我的问题httpd.conf。

# User/Group: The name (or #number) of the user/group to run httpd as.
# It is usually good practice to create a dedicated user and group for
# running httpd, as with most system services.
#
#User daemon
User my_username
Group daemon

本文在Apache 2.2上创建虚拟主机可以帮助我（第9点）对顶级虚拟主机目录的访问权限。

我只需将以下行添加到我的vhosts.conf文件中：

<Directory I:/projects/webserver>
    Order Deny,Allow
    Allow from all
</Directory>

我遇到了同样的错误，并且很长一段时间都无法解决问题。如果您碰巧在包含SELinux之类的Linux发行版（例如CentOS）上，则需要确保已为文档根文件正确设置SELinux权限，否则会出现此错误。这是与标准文件系统权限完全不同的一组权限。

我碰巧使用了Apache和SELinux教程，但是一旦您知道要查找的内容之后，似乎就会发现有很多东西。

如果您使用的是MAMP Pro，则可以通过选中- 选项卡Indexes下的复选框来解决此问题。 HostsExtended

在MAMP Pro v3.0.3中，外观如下：

有另一种方法可以解决此问题。假设您要访问位于的目录“ subphp” /var/www/html/subphp，并且要使用进行访问127.0.0.1/subphp，则会收到如下错误：

您无权访问此服务器上的/ subphp /。

然后将目录权限从“无”更改为“访问文件”。命令行用户可以使用chmod命令来更改权限。

我遇到了同样的问题，但是由于我将apache上的路径更改为var / www以外的文件夹，所以我开始遇到问题。

我通过在var / www / html> home / dev / project中创建一个符号链接来解决此问题，这似乎可以解决问题，而无需更改任何权限...

我使用Mac OS X，就我而言，我只是忘记在apache中启用php，我要做的就是取消注释以下一行/etc/apache2/httpd.conf：

LoadModule php5_module libexec/apache2/libphp5.so

参考此文章的细节。

（在Windows和Apache 2.2.x中）

“禁止”错误也是未定义虚拟主机的结果。

如Julien所述，如果您打算使用virtual hosts.conf，那么请转到httpd文件并取消注释以下行：

#Include conf/extra/httpd-vhosts.conf

然后在其中添加虚拟主机定义conf/extra/httpd-vhosts.conf并重新启动Apache。

我遇到了这个问题，我的解决方案是使www-data不拥有适当的文件夹，而是将它设置为其中一个用户拥有。（我试图做一些幻想，但为了使ftp正常播放而进行了错误的欺骗。）

运行后：

chown -R www-data:www-data /var/www/html

机器再次开始提供数据。您可以通过以下方式查看谁当前拥有该文件夹

ls -l /var/www/html

此解决方案不允许所有人

我只想更改我的公共目录www，并从我的PC和通过Wifi连接的移动设备上访问它。我有Ubuntu 16.04。

1. 因此，首先，我修改了/etc/apache2/sites-enabled/000-default.conf， 并更改了新的公共目录DocumentRoot“ / media / data / XAMPP / htdocs”的行DocumentRoot / var / www / html

2. 然后，我修改了/etc/apache2/apache2.conf，并为本地主机和移动设备放了权限，这一次我使用了IP地址，我知道它不是完全安全的，但是对于我的目的来说还可以。

   <Directory/>
       Options FollowSymLinks
       AllowOverride None
       Order deny,allow
       Deny from all
       Allow from localhost 10.42.0.11
   </Directory>
   

试试这个，不要添加任何东西Order allow,deny和其他：

AddHandler cgi-script .cgi .py 
ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
<Directory "/usr/lib/cgi-bin">
    AllowOverride None
    Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
    Require all granted
    Allow from all
</Directory>

sudo a2enmod cgi
sudo service apache2 restart

    I changed 
    Order Deny,Allow
    Deny From All      in .htaccess to   " Require all denied "    and restarted apache but it did not help.

Ubuntu中apache2.conf的路径是/etc/apache2/apache.conf

然后我在apache2.conf中添加了以下几行，然后我的文件夹工作正常

    <Directory /path of required folder>
            Options Indexes FollowSymLinks
            AllowOverride All
            Require all granted
       </Directory>

   and run  " Sudo service apache2 restart " 

我知道这个问题已经有几个答案，但是我认为有一个非常微妙的方面，尽管已提到，但在先前的答案中并没有充分强调。

在检查Apache配置或文件的权限之前，让我们做一个简单的检查，以确保组成您要访问的文件（例如，文档根目录中的index.php文件）完整路径的每个目录不仅Web服务器用户可读且可执行。

例如，假设您的文档根目录的路径为“ / var / www / html”。您必须确保Web服务器用户可以（读取和）执行所有“ var”，“ www”和“ html”目录。就我而言（Ubuntu 16.04），我错误地将“ x”标志从“ html”目录中移至“其他”组，因此权限如下所示：

drwxr-xr-- 15 root root 4096 Jun 11 16:40 html

如您所见，Web服务器用户（在这种情况下，向其应用“其他”权限的用户）没有对“ html”目录的执行访问权限，而这正是问题的根源。发出后：

chmod o+x html

命令，问题已解决！

在解决这种问题之前，我确实尝试了该线程中的所有其他建议，并且由于该建议被埋在了我几乎是偶然发现的评论中，因此我认为在此处强调和扩展它可能会有所帮助。

我只对特定的控制器有同样的问题-这真的很奇怪。我在CI文件夹的根目录中有一个文件夹，该文件夹的名称与我尝试访问的控制器的名称相同。因此，CI会将请求定向到此目录，而不是控制器本身。

删除此文件夹后（该文件夹有误），一切正常。

更清楚地说，这是它的样子：

/ci/controller/register.php

/ci/register/

我不得不删除/ci/register/。

确切检查文件放置位置，不要将它们嵌套在“文档”文件夹中。

例如，我犯了一个错误，因为我提到的将代码放在Documents文件夹中的方法是行不通的，因为Documents明确仅对您可用，而不对APACHE有效。尝试将其上移一个目录，您可能不会看到此问题。

将文件夹从：

/用户/您的用户名/文档/代码

到这里：/ Users / YOURUSERNAME /代码

我也想对这个问题做出另一贡献：

我配置了一个我不想的VirtualHost。我已经注释掉了虚拟主机包含所在的行，并且行得通。

您可以youralias.conf像以下代码那样更改文件：

Alias /Quiz/ "h:/MyServer/Quiz/" 
 <Directory "h:/MyServer/Quiz/">
   Options Indexes FollowSymLinks
   AllowOverride all
   <IfDefine APACHE24>
     Require local
   </IfDefine>
   <IfDefine !APACHE24>
    Order Deny,Allow
    Deny from all
    Allow from localhost ::1 127.0.0.1
   </IfDefine>
 </Directory>

请记住，在这种情况下要配置的正确文件不是phpMyAdmin别名中的httpd.conf，而是 bin/apache/your_version/conf/httpd.conf。

查找以下行：

DocumentRoot "c:/wamp/www/"

#
# Each directory to which Apache has access can be configured with respect
# to which services and features are allowed and/or disabled in that
# directory (and its subdirectories).
#
# First, we configure the "default" to be a very restrictive set of
# features.
#
<Directory />
    Options FollowSymLinks
    AllowOverride None
    Order deny,allow
    Allow from all
</Directory>

确保将其设置为 Allow from all ...

如果没有，phpMyAdmin甚至可以工作，但是您的根目录和它下面的其他文件夹却不起作用。另外，请记住重新启动WAMP，然后将其联机...

这解决了我的头痛。

在运行docker build之前，使用SSHFS从本地文件系统中的VirtualBox guest虚拟机中挂载文件时遇到了这个问题。最后，“修复”是将所有文件复制到VirtualBox实例，而不是从SSHFS装载内部进行构建，然后从那里运行构建。

工作方法（除非没有其他问题）

默认情况下，Apache不会限制从IPv4（公共外部IP地址）的访问

受限制的是“httpd.conf '中。

全部替换

<Directory />
    AllowOverride none
    Require all denied
</Directory>

与

<Directory />
    AllowOverride none
    # Require all denied
</Directory>

因此消除了对Apache的所有限制。

更换Require local用Require all granted的/ WAMP / WWW /：C目录。

<Directory "c:/wamp/www/">
    Options Indexes FollowSymLinks
    AllowOverride all
    Require all granted
    # Require local
</Directory>

更改配置文件后，不要忘记 Restart All Services。

我浪费了三个小时。

这非常荒谬，但是当我尝试下载的文件不在文件系统上时，我收到了403 Forbidden。在这种情况下，apache错误不是很准确，在我将文件放置在原本应该的位置之后，整个工作就可以了。
