> Apache is rock solid. That's a fact. Keep reading to see how many web sites support this fact.
> php-fcgi is unstable, and unreliable. That's a fact. It's no joke when a web site goes down on a production server. Down time is lost money.
> The forums are saturated with complaints about the instability and unreliability of php-fcgi, etc., serving PHP for Nginx and other servers that don't serve PHP themselves.
As they are with Apache dying. Google it.
> When Apache, or Litespeed, are used on the backend to serve PHP for Nginx, and those other static file servers like Zeus and lighttpd, there are zero complaints, because Apache is reliable and stable when serving PHP.
Zero complaints? You know this for a fact? Zero? You must be kidding.
Making statements like this does little for your credibility.
> When you say:
> Apache cannot handle the load on the same hardware.
> ... you must have never used Apache to serve millions of request, because I have, and I know you have no idea what you're talking about, and the system administrators handling some of the biggest web sites on the Internet also know you don't have a clue about Apache's abilities.
> You said:
> php-fpm handles millions of requests a day for me without an issue.
> Post the URL to your web site that handles millions of requests a day, because I believe you're claim is a lie. The only site I can find for you is http://michaelshadle.com/, and that doesn't get much traffic at all.
That's out of line. Just because YOU cannot find it does not mean it is
not there. It is, but you don't know where to look and Mike is not going
to share it to satisfy your need to know. You're wrong on this one.

And some use nginx. As for how they handle PHP, that is speculation.
> What's more important is that there is no way to know how many web sites are using Apache or lighttpd as a backend server to handle PHP, since those people never complain about problems, and the small number of web sites that do try to use php-fcgi complain on forums all over the Internet about problems with reliability and stability.
> Those are the facts Mike. Your support for php-fcgi sounds more like an opinion than a statement based on fact.
This may be but your claim that there are zero complaints with Apache
and that Apache is "rock solid" and never goes down is also an opinion
that happens to be wrong. I have myself seen it go down. Of course we
were only handling 4 million requests/day at the time and we were using
Apache with mod_perl to serve a Perl script, so it wasn't PHP. That's
why I had supervisord installed. It can restart php-cgi just as easily
(and probably php-fpm but I haven't tried it) as it can Apache and even
nginx. The fact that I never posted my experience on a forum doesn't
mean it never happened.
> I've seen your comments here about how much you love php-fpm. Giving people the impression that php-fcgi is the only option they have to handle PHP on the backend, can mislead someone into many hours or days of frustration that can lead them into dumping Nginx, because they blame Nginx for the problems caused by php-fcgi. I suggest balancing your advice with other options like Apache.
This is a fair comment. Mike loves php-fpm and is perhaps biased. So sue
This "discussion" probably does not belong on the nginx list and should
perhaps be taken private between you two if it needs to continue.
