#1: switching from mod_fastcgi to mod_fcgid

Hello,

I would like to switch from mod_fastcgi to mod_fcgid.
In my current configuration I have something like:

-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-

jcigar@bebif cgi-bin % pwd
/usr/local/www/apache22/cgi-bin
jcigar@bebif cgi-bin % cat tapir-php-wrapper.fcgi
#!/bin/sh

PHPRC="/usr/local/etc/php.ini"
export PHPRC

PHP_FCGI_CHILDREN=3
export PHP_FCGI_CHILDREN

PHP_FCGI_MAX_REQUESTS=10000
export PHP_FCGI_MAX_REQUESTS

exec /usr/local/bin/php-cgi -b 127.0.0.1:5000

-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-

Every webapp runs under a dedicated user, so I'm using sudo -u ... to
launch the PHP "wrapper", and then I'm using the FastCgiExternalServer
directive of mod_fastcgi to "link" the php-cgi processes to Apache. I
have something like this in my Apache configuration file:

-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-

FastCgiExternalServer
/usr/local/www/apache22/cgi-bin/tapir-php-wrapper.fcgi -host
127.0.0.1:5000 -idle-timeout 1800

Action php-fastcgi /cgi-bin/tapir-php-wrapper.fcgi

AddHandler php-fastcgi .php

-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-%-

The advantage of this configuration is that I can launch the process
under a dedicated user without using mod_suexec (which has more
constraints).

I wondered if there is a FastCgiExternalServer equivalent in mod_fcgid
and also if mod_suexec is the only way in mod_fcgid to launch a PHP
webapp under a dedicated user?

Thanks,
Julien

no

long-term solution for externally managed FastCGI applications is
mod_proxy_fcgi in future Apache 2.4

(or keep using mod_fastcgi)

yes

Yes, I plan to switch to mod_proxy_fcgi once Apache 2.4 is out (as I did
with mod_jk -> mod_proxy_ajp)

I'm happy with mod_fastcgi in fact, but ~once a month I have to restart
Apache because it doesn't respond to requests anymore (I get a "The
connection was reset" in my browser) ... and I suspect that mod_fastcgi
*could* be the cause of this (or mod_passenger)

That's what I thought ..

Thanks for your answer,
