如何在 Debian 上的 Apache 2.4 中为每个虚拟主机选择 PHP 版本 5 和 7？

How to select PHP version 5 and 7 per virtualhost in Apache 2.4 on Debian?

提问by Z0q

Would it be possible to run PHP 7 and PHP 5 simultaneously in Apache 2.4 on Debian 9? I would like to be able to select the PHP version I wish to use per virtualhost. I believe this would be useful considering that some of my websites still use deprecated PHP features. This allows me to perform upgrades per site. How do I achieve something like this?

是否可以在 Debian 9 上的 Apache 2.4 中同时运行 PHP 7 和 PHP 5？我希望能够为每个虚拟主机选择我希望使用的 PHP 版本。考虑到我的一些网站仍然使用不推荐使用的 PHP 功能，我相信这会很有用。这允许我执行每个站点的升级。我如何实现这样的目标？

For example

例如

<VirtualHost *:80>
   ServerAdmin webmaster@localhost
   ServerName mywebsite.com
   DocumentRoot /var/www/mywebsite.com

   # UsePHP 7
</virtualHost>

And

和

<VirtualHost *:80>
   ServerAdmin webmaster@localhost
   ServerName mywebsite2.com
   DocumentRoot /var/www/mywebsite2.com

   # UsePHP 5
</virtualHost>

Let's start from beginning. I assume that you would prefer to use php-fpm instead of Apache module.

让我们从头开始。我假设您更喜欢使用 php-fpm 而不是 Apache 模块。

First install apache:

首先安装apache：

sudo apt-get update
sudo apt-get install apache2

Next install multiple PHP:

接下来安装多个PHP：

Debian 9:
Install PHP 7:

Debian 9：
安装 PHP 7：

sudo apt-get install php7.0-cli php7.0-fpm php-pear libapache2-mod-fastcgi

Configure repositories:

配置存储库：

sudo apt-get install apt-transport-https
sudo curl https://packages.sury.org/php/apt.gpg | apt-key add -
sudo echo 'deb https://packages.sury.org/php/ stretch main' > /etc/apt/sources.list.d/deb.sury.org.list
sudo apt-get update

Install PHP 5:

安装 PHP 5：

sudo apt-get install php5.6-cli php5.6-fpm

Debian 8:
Install PHP 5:

Debian 8：
安装 PHP 5：

sudo apt-get install php5 php5-fpm php-pear libapache2-mod-fastcgi

Configure repositories:
Edit /etc/apt/sources.listand add the following lines to the end of file:

配置存储库：
编辑/etc/apt/sources.list以下行并将其添加到文件末尾：

deb http://packages.dotdeb.org jessie all
deb-src http://packages.dotdeb.org jessie all

Install GPG key:

安装 GPG 密钥：

wget https://www.dotdeb.org/dotdeb.gpg
sudo apt-key add dotdeb.gpg
sudo apt-get update

Install PHP 7:

安装 PHP 7：

sudo apt-get install php7.0 php7.0-fpm

Next switch from prefork and enable necessary modules:
For Debian 8:

接下来从 prefork 切换并启用必要的模块：
对于 Debian 8：

a2dismod php5 mpm_prefork

For Debian 9:

对于 Debian 9：

a2dismod php7 mpm_prefork

Next for both:

接下来是：

a2enmod actions fastcgi alias proxy_fcgi mpm_worker
systemctl restart apache2

Change content of /etc/apache2/mods-enabled/fastcgi.confto the following one:

将 的内容更改/etc/apache2/mods-enabled/fastcgi.conf为以下一项：

<IfModule !mod_fastcgi.c>
    AddHandler fcgid-script fcg fcgi fpl
</IfModule>
<IfModule mod_fastcgi.c>
    <Directory /usr/lib/cgi-bin>
        Require all granted
    </Directory>
</IfModule>

Now create document root folders for websites:

现在为网站创建文档根文件夹：

mkdir -p /var/www/example.com/public_html
mkdir -p /var/www/test.com/public_html

Add sys users for these websites:

为这些网站添加 sys 用户：

sudo useradd example --home-dir /var/www/example.com
sudo useradd test --home-dir /var/www/test.com

Configure ownership:

配置所有权：

sudo chown -R example.example /var/www/example.com
sudo chown -R test.test /var/www/test.com

For example website example.comwill use PHP 5 and website test.comwill use PHP 7.

例如网站example.com将使用 PHP 5，网站test.com将使用 PHP 7。

Create configuration files for websites:
Website on PHP 5:

为网站创建配置文件：
PHP 5 网站：

touch /etc/apache2/sites-available/example.com.conf
ln -s /etc/apache2/sites-available/example.com.conf /etc/apache2/sites-enabled/example.com.conf
cat /etc/apache2/sites-available/example.com.conf
<VirtualHost *:80>

        ServerAdmin webmaster@localhost
        ServerName example.com
        ServerAlias www.example.com
        DocumentRoot /var/www/example.com/public_html
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        <IfModule mod_fastcgi.c>
            AddType application/x-httpd-fastphp5 .php
            Action application/x-httpd-fastphp5 /php5-fcgi
            Alias /php5-fcgi /usr/lib/cgi-bin/php5-fcgi-example.com
            FastCgiExternalServer /usr/lib/cgi-bin/php5-fcgi-example.com -socket /var/run/php5-fpm-example.com.sock -pass-header Authorization
        </IfModule>

</VirtualHost>

Website on PHP 7:

PHP 7 网站：

touch /etc/apache2/sites-available/test.com.conf
ln -s /etc/apache2/sites-available/test.com.conf /etc/apache2/sites-enabled/test.com.conf
cat /etc/apache2/sites-available/test.com.conf
<VirtualHost *:80>

        ServerAdmin webmaster@localhost
        ServerName test.com
        ServerAlias www.test.com
        DocumentRoot /var/www/test.com/public_html
        ErrorLog ${APACHE_LOG_DIR}/error.log
        CustomLog ${APACHE_LOG_DIR}/access.log combined

        <IfModule mod_fastcgi.c>
                AddHandler php7-fcgi .php
                Action php7-fcgi /php7-fcgi virtual
                Alias /php7-fcgi /usr/lib/cgi-bin/php7-fcgi-test.com
                FastCgiExternalServer /usr/lib/cgi-bin/php7-fcgi-test.com -socket /var/run/php/php7.0-fpm-test.com.sock -pass-header Authorization
        </IfModule>

</VirtualHost>

Create pool configs (I used the following):
Website on PHP 5:

创建池配置（我使用了以下内容）：
PHP 5 网站：

cat /etc/php5/fpm/pool.d/example.com.conf
[example.com]
user = example
group = example
listen = /var/run/php5-fpm-example.com.sock
listen.owner = www-data
listen.group = www-data
php_admin_value[disable_functions] = exec,passthru,shell_exec,system
php_admin_flag[allow_url_fopen] = off
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
chdir = /

Website on PHP 7:

PHP 7 网站：

cat /etc/php/7.0/fpm/pool.d/test.com.conf
[test.com]
user = test
group = test
listen = /var/run/php/php7.0-fpm-test.com.sock
listen.owner = www-data
listen.group = www-data
php_admin_value[disable_functions] = exec,passthru,shell_exec,system
php_admin_flag[allow_url_fopen] = off
pm = dynamic
pm.max_children = 5
pm.start_servers = 2
pm.min_spare_servers = 1
pm.max_spare_servers = 3
chdir = /

Restart apache and php-fpm services:

重启apache和php-fpm服务：

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

Enjoy!

享受！

The answer by @elvis-pleskyis really detailled. But Apache suggeststhe usage of mod_proxy_fcgi:

@elvis-plesky的回答非常详细。但 Apache建议使用mod_proxy_fcgi：

With the release of apache httpd 2.4 upon an unsuspecting populace, we have gained some very neat functionality regarding apache and php: the ability to run PHP as a fastCGI process server, and address that fastCGI server directly from within apache, via a dedicated proxy module (mod_proxy_fcgi.)

随着 apache httpd 2.4 在毫无戒心的人群中发布，我们获得了一些关于 apache 和 php 的非常简洁的功能：能够将 PHP 作为 fastCGI 进程服务器运行，并通过专用代理模块直接从 apache 内部寻址该 fastCGI 服务器（mod_proxy_fcgi。）

Here are the steps to setup two vhosts with different PHP versions for Debian 10using Apache's mod_proxy_fcgi and php-fpm.

以下是使用 Apache 的 mod_proxy_fcgi 和 php-fpm为Debian 10设置两个具有不同 PHP 版本的虚拟主机的步骤。

Configure repositories:

配置存储库：

sudo apt-get install apt-transport-https
sudo curl https://packages.sury.org/php/apt.gpg | apt-key add -
sudo echo 'deb https://packages.sury.org/php/ stretch main' > /etc/apt/sources.list.d/deb.sury.org.list
sudo apt-get update

Install needed PHP versions:

安装所需的 PHP 版本：

sudo apt-get install php5.6-cli php5.6-fpm php7.3-cli php7.3-fpm

Configure php5.6-fpm in /etc/apache2/conf-available/php5.6-fpm.conf:

在 php5.6-fpm 中配置/etc/apache2/conf-available/php5.6-fpm.conf：

<IfModule !mod_php5.c>
<IfModule proxy_fcgi_module>
    # Enable http authorization headers
    <IfModule setenvif_module>
        SetEnvIfNoCase ^Authorization$ "(.+)" HTTP_AUTHORIZATION=
    </IfModule>

    <FilesMatch ".+\.ph(ar|p|tml)$">
        SetHandler "proxy:unix:/run/php/php5.6-fpm.sock|fcgi://php56.localhost"
    </FilesMatch>
    # Deny access to files without filename (e.g. '.php')
    <FilesMatch "^\.ph(ar|p|ps|tml)$">
        Require all denied
    </FilesMatch>
</IfModule>
</IfModule>

Configure php7.3-fpm in /etc/apache2/conf-available/php7.3-fpm.conf:

在 php7.3-fpm 中配置/etc/apache2/conf-available/php7.3-fpm.conf：

<IfModule !mod_php7.c>
<IfModule proxy_fcgi_module>
    # Enable http authorization headers
    <IfModule setenvif_module>
        SetEnvIfNoCase ^Authorization$ "(.+)" HTTP_AUTHORIZATION=
    </IfModule>

    <FilesMatch ".+\.ph(ar|p|tml)$">
        SetHandler "proxy:unix:/run/php/php7.3-fpm.sock|fcgi://php73.localhost"
    </FilesMatch>
    # Deny access to files without filename (e.g. '.php')
    <FilesMatch "^\.ph(ar|p|ps|tml)$">
        Require all denied
    </FilesMatch>
</IfModule>
</IfModule>

Now add a virtual host that uses PHP 5.6:

现在添加一个使用 PHP 5.6 的虚拟主机：

<VirtualHost *:80>
    ServerName test-php56.localhost
    DocumentRoot "/var/www/test-php56/"
    # use php 5.6
    <FilesMatch ".+\.ph(ar|p|tml)$">
        SetHandler "proxy:unix:/run/php/php5.6-fpm.sock|fcgi://php56.localhost"
    </FilesMatch>
</VirtualHost>

And a virtual host that uses PHP 7.3:

还有一个使用 PHP 7.3 的虚拟主机：

<VirtualHost *:80>
    ServerName test-php73.localhost
    DocumentRoot "/var/www/test-php73/"
    # use php 7.3
    <FilesMatch ".+\.ph(ar|p|tml)$">
        SetHandler "proxy:unix:/run/php/php7.3-fpm.sock|fcgi://php73.localhost"
    </FilesMatch>
</VirtualHost>

Activate the correct Apache module and the configs:

激活正确的 Apache 模块和配置：

sudo a2enmod proxy_fcgi
sudo a2enconf php5.6-fpm
sudo a2enconf php7.3-fpm
sudo systemctl restart apache2 php5.6-fpm php7.3-fpm

The default configuration of the FPM pools should be correct already.

FPM 池的默认配置应该已经正确。
