[users@httpd] mod_fcgid working via cli but fails with the browser

[JvR O]

I'm trying to execute different versions of PHP for different VirtualHosts

The default version of PHP is 5.3.3

I have installed a php v5.4.18 at /var/www/vhosts/example.com/php-5.4.18for the
example.com project
I have installed mod_fcgid to use it for new virtual hosts.

I'm testing with a phpinfo() file to get the php version used and see if
php is executed via FastCGI in the new virtual host.

There is a problem to execute the file in the browser correctly.
The phpinfo.php file is not being executed the response is 500 status code
(Internal Server Error)

The error_log:
[Tue Sep 10 18:48:29 2013] [warn] [client 192.168.1.12] (104)Connection
reset by peer: mod_fcgid: error reading data from FastCGI server
[Tue Sep 10 18:48:29 2013] [error] [client 192.168.1.12] Premature end of
script headers: phpinfo.php

I can execute the phpinfo.php file via CLI with
/var/www/vhosts/example.com/php-5.4.18/bin/php-cgi /var/www/vhosts/
example.com/httpdocs/Symfony/web/phpinfo.php > /var/www/vhosts/
example.com/httpdocs/Symfony/web/phpinfo2.txt

At the txt file
X-Powered-By: PHP/5.4.18
<tr><td class="e">Server API </td><td class="v">CGI/FastCGI </td></tr>

Then is correct, when is executed via CLI.

This /var/www/vhosts/example.com/php-5.4.18/bin/ directory is not in the
PATH but if I add to the $PATH.
Which will be executed?
If there is another script with the same name php-cgi at /usr/bin which is
already in the $PATH


The configuration:
-----------

<VirtualHost 192.168.1.12:80>

     ServerName   "example.com.localhost"
     ServerAlias  "www.example.com.localhost"
     ServerAdmin  "ad...@example.com.localhost"
     DocumentRoot /var/www/vhosts/example.com/httpdocs/Symfony/web

    ErrorLog  "/var/www/vhosts/example.com/statistics/logs/error_log"

<Directory /var/www/vhosts/example.com/httpdocs/Symfony/web>

         AddHandler fcgid-script .php
         Options +ExecCGI
         FcgidWrapper /var/www/vhosts/example.com/cgi-bin/php-fcgi .php
         Order allow,deny
         Allow from all

    php_admin_value open_basedir ".:/var/www/vhosts/example.com:
/usr/share/pear:/tmp"
    php_admin_value include_path ".:/usr/share/pear"

</Directory>

<Directory "/var/www/vhosts/example.com/cgi-bin">

    SetHandler fcgid-script
    Options +ExecCGI

    # Customize the next two directives for your requirements.
    Order allow,deny
    Allow from all

</Directory>

# apache settings for virtual host
     php_value memory_limit 256M

</VirtualHost>

------

The FCGIWrapper at /var/www/vhosts/example.com/cgi-bin/php-fcgi:
------
#!/bin/sh
PHPRC=/var/www/vhosts/example.com/php-5.4.18/etc/
export PHPRC
PHP_CGI=/var/www/vhosts/example.com/php-5.4.18/bin/php-cgi
export PHP_FCGI_MAX_REQUESTS=5000
export PHP_FCGI_CHILDREN=8
exec $PHP_CGI
------

I have used this commands for the file
chmod +x php-fcgi, anyway has got 755


Why is working via CLi but is not working with the browser?
