在deepin20系统中安装apache2之后改变目录，访问出现403错误？

Question

如标题所述，我出现了如下错误：
Forbidden
You don't have permission to access this resource.

Apache/2.4.38 (Uos) Server at localhost Port 80
我能够想到的是目录没有权限，因此对目录已经设置了权限

配置文件如下：

<VirtualHost *:80>
    # The ServerName directive sets the request scheme, hostname and port that
    # the server uses to identify itself. This is used when creating
    # redirection URLs. In the context of virtual hosts, the ServerName
    # specifies what hostname must appear in the request's Host: header to
    # match this virtual host. For the default virtual host (this file) this
    # value is not decisive as it is used as a last resort host regardless.
    # However, you must set it for any further virtual host explicitly.
    #ServerName www.example.com

    ServerAdmin webmaster@localhost
    DocumentRoot /home/leomus/www

    # Available loglevels: trace8, ..., trace1, debug, info, notice, warn,
    # error, crit, alert, emerg.
    # It is also possible to configure the loglevel for particular
    # modules, e.g.
    #LogLevel info ssl:warn
        
    <Directory "/home/leomus/www"> 
        Options FollowSymLinks 
        AllowOverride None 
        Order deny,allow
        Allow from all 
    </Directory> 
    ErrorLog ${APACHE_LOG_DIR}/error.log
    CustomLog ${APACHE_LOG_DIR}/access.log combined

        # or most configuration files from conf-available/, which are
    # enabled or disabled at a global level, it is possible to
    # include a line for only one particular virtual host. For example the
    # following line enables the CGI configuration for this host only
    # after it has been globally disabled with "a2disconf".
    #Include conf-available/serve-cgi-bin.conf
</VirtualHost>

# vim: syntax=apache ts=4 sw=4 sts=4 sr noet

期间我修改目录成var/www/html
成初始状态，但是无法运行php
**无法运行PHP的问题已经解决是缺少插件，安装相关组件即可运行PHP
安装组件命令如下**

 sudo apt install php7.3-mysql php7.3-curl php7.3-gd php7.3-intl php-pear php7.3-imagick 

但是仍然不能修改目录，这个目录是正常且路径是存在的。
我系统里面安装了PHP7.3

我实在找不出问题所在了，有知道兄弟麻烦解答一下，谢谢！

补充问题：我发现只要网站目录换成apache2默认的目录暨：/var/www/html

网站就能正常，如果换成其他任何目录就不行!

这是什么原理，搞不明白！

Answer 1

更改目录权限

确保目录及其所有子目录和文件具有正确的权限，通常使用 755 权限。具体操作步骤：

chmod -R 755 /path/to/your/new/directory

更改目录所有者

确保 Apache 用户（通常是 www-data 或 apache）拥有该目录及其内容的所有权：

# 如果Apache用户是www-data
chown -R www-data:www-data /path/to/your/new/directory

确认Apache的运行用户和组与新目录的所有者和组一致。可以在/etc/apache2/envvars文件中设置Apache的运行用户和组：

export APACHE_RUN_USER=youruser
export APACHE_RUN_GROUP=yourgroup

如果Apache用户是apache

chown -R apache:apache /path/to/your/new/directory

### 验证权限和所有权
使用以下命令检查目录的权限和所有权：

ls -l /path/to/your/new/directory

你应该看到类似于以下的输出：

drwxr-xr-x 2 www-data www-data 4096 Nov 9 21:58 your-directory

### 更新Apache配置文件
确保在 Apache 配置文件中正确配置了新目录。例如，在 `/etc/apache2/apache2.conf` 中添加或修改以下内容：

<Directory "/path/to/your/new/directory">

Options Indexes FollowSymLinks
AllowOverride None
Require all granted

</Directory>

### 重启Apache服务
每次修改配置文件后，记得重启 Apache 服务以应用更改：

sudo systemctl restart apache2
