php7.0-fpm not working with apache2.4 on Ubuntu-16.04

Question

I'm using Ubuntu-16.04 to establish an apache server. I use php-fpm to handle php files. I followed this post. After configuration, my apache2 and php7.0-fpm services restarted correctly. But when I browse a php file I got a plain file. It seems that there is no php cgi to handle the php file. What's wrong with me?

I'm new to apache. So I don't know what configurations to paste. I will post the necessary configurations according to your answers. Thx!

My installation steps:

Install PHP and PHP-fpm:

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

Enable the fastcgi mods

sudo a2dismod php mpm_prefork
sudo a2enmod actions fastcgi alias mpm_worker

Create a global config for php7.0-fpm

sudo vim /etc/apache2/conf-available/php7.0-fpm.conf

And write in the configurations:

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

Then Enable the php7.0-fpm conf

sudo a2enconf php7.0-fpm

Restart apache and fpm

sudo service apache2 restart && sudo service php7.0-fpm restart

Edit /var/www/html/index.php:

<?php
phpinfo();
?>

Then browse http://localhost/index.php, but got the file content instead of the printed page.

Solution

Your configurations are a little bit off. Try this:

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

I add it this here, and works well: /etc/apache2/sites-available/000-default.conf

No one wants to read some external tutorial to get an idea what you might have done wrong. So just post the files you adapted as a start.

@Sven Thanks for your remind. I have described my installation steps briefly.

ls /var/run/php7.0.fpm.sock?
