Sample setup for Apache virtual host and PHP-FPM pool with variables instead hard coded user details.
This could be handy if your are scripting your deploy (e.g. with Ansible).

In our example we are using the following:

Domain: example.com
SFTP user: example.com
Document root: /var/www/vhosts/example.com/httpdocs/

<VirtualHost *:80>
        ServerName example.com
        ServerAlias www.example.com

        DocumentRoot /var/www/vhosts/example.com/httpdocs
        <Directory /var/www/vhosts/example.com/httpdocs>
                require all granted
                Options Indexes
                AllowOverride All
        </Directory>

        ErrorLog "logs/example.com-error_log"
        CustomLog "logs/example.com-access_log" combined env=!forwarded
        CustomLog "logs/example.com-access_log" proxy env=forwarded

	# Configure proxy connector
	<Proxy "unix:/dev/shm/example.com-php5-fpm.sock|fcgi://php-fpm">
    		# we must declare a parameter in here (doesn't matter which) or it'll not register the proxy ahead of time
	    	ProxySet disablereuse=off
	</Proxy>
	#
	# Redirect to the proxy connector
	<FilesMatch \.php$>
    		SetHandler proxy:fcgi://php-fpm
	</FilesMatch>


        <Directory /var/www/vhosts/example.com/httpdocs/wp-content/uploads>
            # Important for security, prevents someone from
            # uploading a malicious .htaccess
            AllowOverride None

            SetHandler none
            SetHandler default-handler

            Options -ExecCGI
            php_flag engine off
            RemoveHandler .cgi .php .php3 .php4 .php5 .phtml .pl .py .pyc .pyo
            <Files *>
                    AllowOverride None

                    SetHandler none
                    SetHandler default-handler

                    Options -ExecCGI
                    php_flag engine off
                    RemoveHandler .cgi .php .php3 .php4 .php5 .phtml .pl .py .pyc .pyo
            </Files>
        </Directory>
</VirtualHost>

Create a file called example.com.conf in /etc/php-fpm/pool/

[example.com]

listen = /dev/shm/$pool-php5-fpm.sock
user = $pool
group = $pool
listen.owner = $pool
listen.group = apache
listen.mode = 0666

pm = dynamic
pm.max_children = 35
pm.start_servers = 5
pm.min_spare_servers = 5
pm.max_spare_servers = 25
slowlog = /var/log/php-fpm/$pool-slow.log
php_admin_value[error_log] = /var/log/php-fpm/$pool-error.log
php_admin_flag[log_errors] = on
php_value[session.save_handler] = files
php_value[session.save_path] = /var/lib/php/session/$pool
