Apache 2.4 + PHP-FPM + ProxyPassMatch 使用 Unix 套接字

我尝试使用 Unix 套接字设置 Apache v2.4 + PHP-FPM + ProxyPassMatch。

使用 Debian 9 Stretch、PHP v5.6.37、PHP v7.0.31、Apache v2.4.25。

我的虚拟主机设置如下（000-default.conf）：

<VirtualHost *:80>
    ServerAdmin webmaster@localhost
    ServerName local.lc

    DocumentRoot /var/www

    ProxyPassMatch "^/(.*\.php(/.*)?)$" "unix:/var/run/php5.6-fpm.sock|fcgi://localhost/var/www/"

    <Directory />
        Options FollowSymLinks
        AllowOverride None
    </Directory>
    <Directory /var/www/>
        Options Indexes FollowSymLinks MultiViews
        AllowOverride None
        Order allow,deny
        allow from all
    </Directory>

    ScriptAlias /cgi-bin/ /usr/lib/cgi-bin/
    <Directory "/usr/lib/cgi-bin">
        AllowOverride None
        Options +ExecCGI -MultiViews +SymLinksIfOwnerMatch
        Order allow,deny
        Allow from all
    </Directory>

    ErrorLog ${APACHE_LOG_DIR}/error.log

    # Possible values include: debug, info, notice, warn, error, crit,
    # alert, emerg.
    LogLevel warn

    CustomLog ${APACHE_LOG_DIR}/access.log combined
</VirtualHost>

我执行了以下命令：

sudo apt-get install php7.0-cli php7.0-fpm php-pear libapache2-mod-fcgid
sudo apt install software-properties-common
# add repo to get PHP5
sudo apt-get -y install apt-transport-https lsb-release ca-certificates
sudo curl https://packages.sury.org/php/apt.gpg | apt-key add -
sudo wget -O /etc/apt/trusted.gpg.d/php.gpg https://packages.sury.org/php/apt.gpg
sudo echo 'deb https://packages.sury.org/php/ stretch main' > /etc/apt/sources.list.d/deb.sury.org.list
sudo apt-get update
sudo apt-get install php5.6-cli php5.6-fpm
sudo apt-get install php7.0 php7.0-fpm
sudo a2enconf php5.6-fpm
sudo systemctl reload apache2
sudo a2dismod php5 php7 php5.6 php7.0 mpm_prefork
sudo a2enmod actions alias proxy_fcgi mpm_worker
sudo systemctl restart apache2 php5.6-fpm php7.0-fpm

更改后使用以下命令重新启动服务器：

sudo systemctl restart apache2 php5.6-fpm php7.0-fpm

我得到空页面，当我加载

http://local.lc/

我的基于 Windows 的开发计算机上的网站。local.lc 位于“hosts”文件中。

我在日志 (/var/log/apache2/error.log) 中看到以下内容：

我在日志中看不到任何帮助。

知道可能出了什么问题吗？

为什么默认页面没有加载？
