Re: [PHP] Red Hat 9, Apache 2, and PHP
Hello Jeff Schwartz, I heard that Apache 2 is not a stable web server using PHP parser, for this reasoun I think that in the php.net web site have said that. bye. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
RE: [PHP] Red Hat 9, Apache 2, and PHP
Hi, that sounds really impressive. I'm using Redhat 9 with the stuff from their Edition, that means Apache 2 and php together. Never had any issues (so far.keep my fingers crossed). The server is not under heavy load, but it is indeed a production server. I know it is not recommended, but for this use (mysql apache php on that server in a company intranet, used for keeping a picture library administration issues) is it necessary to change it? Please advise. To my defence I have to say that the data on the server is backed up regularly, though not the OS itself, since if something ever happens it is less hassle to do a complete new install get the database back on. Any hints? Thanks Diana --- Rasmus Lerdorf [EMAIL PROTECTED] schrieb: Apache2 has a number of different modes it can work in. These modes are called MPM's. The default MPM is called Worker which is a multithreaded model. PHP, mod_perl, mod_python, and any other similar technology which links directly into the httpd processes will need to be perfectly threadsafe and reentrant to work effectively with a threaded Apache2 mpm. This is doable for the core of PHP, but there are literally hundreds of 3rd party libraries that can be linked into PHP and nobody whether or not these libraries are threadsafe. And figuring out if a specific library is threadsafe or not is non-trivial and it can very from one platform to another. And just to make it even harder, this stuff will appear to work fine until you put it under load or hit very specific race conditions which makes it nearly impossible to debug. So, since we can't tell you for sure that a threaded Apache2 mpm + PHP will work we do not suggest you use it for a production server. And since we can't know for sure, none of the main PHP developers use this combination for our own servers which compounds the problem because it is not receiving anywhere near the amount of realworld testing required to work out all the little issues above and beyond this threading unknown. There is an Apache2 mpm, called prefork, which isn't threaded and basically makes Apache2 look like Apache1. But hey, we have a very good server already that looks like Apache1. In the end I don't see Apache2+PHP ever becoming a production platform with the current architecture. The only way I see it ever working is to pull PHP out of Apache and use a fastcgi approach. Or, with time, perhaps we will learn how to make sure a library is perfectly threadsafe and safe to use in a multithreaded Apache2. For now, I really see no reason not to simply use Apache1 if you want a robust, fast and stable web server. -Rasmus = WHEN ALL ELSE FAILS, HUG YOUR SNOOPY Those who bring sunshine to the lives of others cannot keep it from themselves.

But on gentoo I use apache 2.0, it not for production nor development. Lots of problems, Perhaps RH solve someting using own patch, and I repead if you gonna build production server. Stay away Apache 2.0 Basicly, when you ecounter a problem, then ask question here, first response Use Apache 1.3.27 or someting like that.

-Original Message- From: Jeff Schwartz [mailto:[EMAIL PROTECTED] Sent: 03 July 2003 18:52 The PHP site (under Servers-Apache 2.0) says Do not use Apache 2.0 and PHP in a production environment neither on Unix nor on Windows Well, that's a clumsily-worded sentence all around (I would guess from a non-native English user!). I assume the writer was trying to emphasize that he meant not to use it on any platform, but really Do not use Apache 2.0 and PHP in a production environment just about says it all without the embellishment. but isn't clear whether Linux is included Yes, it is. (And MacOS X!) or whether it applies to all Apache 2 releases (such as 2.0.46) or just the original 2.0. 2.0 can usually be taken to mean 2.0.x, and it can in this instance, too. HTH Cheers!

Thanks, Jeff When someone says UNIX, they're generally including Linux and BSD, as both are UNIX clones. At this point anyone in their right mind is going to suggest you stick with Apache 1.3.x. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
