It looks like perl and PHP are getting in each others way, should I try
and make a new apache? what order should I do things in? Should I look
for another job? :), I need to get it working quickly and with the
minimum disruption to the server. Every time I try and do things like
this on a RAQ something breaks something else, usually its the GUI and I
get about 50 phone calls.
If you must resolve urgently this problem, you can consider the possibility
to proxy all mod_perl requests to an Apache/mod_perl enabled on a different
port (also this save more memory).

Re: Seg Fault with PHP and Perl together
Check the mail archives for this list, there was a thread about using perl and
php together not that long ago. I think that one suggestion was to compile
mod_perl statically with apache, and to load php as a module. Also, you may want
to upgrade your perl to at least 5.6.1, if not 5.8.0. Are you using apache
1.3.26? (anything older has a well-known security exploit). What version of
mod_perl?

I needed to get PHP running on the same box, so I made the module, added it into the httpd.conf and PHP was working fine - Except that it broke the perl sites. ( Disclaimer: I don't use PHP. :) Check out the mod_perl List archives, a number of people are doing this kind of thing and there was a thread very recently about it. You may perhaps find you need to compile a new Apache (static linking instead of DSO), but it's no big deal. But I'd first check those archives, and maybe make sure that I'd used the same compiler for the PHP module build as was used for Apache and mod_perl. It's worth checking the options used as well, things like large file support can cause problems if they're not the same for each build. I don't know if there are any issues with the versions of the various bits of software you're using, there might be. Perl 5.005 is getting a little long in the tooth now, and you didn't say which Apache 1.3 you have, there are lots of them... I wouldn't expect the problem to be related to EmbPerl but you never know. There's an EmbPerl site, check out the mod_perl home page for the address, but Gerald Richter reads the posts here too. And yes, it sometimes does matter what order you do things in - you might find that the order of loading modules is important - but I don't know of any particular problem with the modules you mentioned. You could make a completely new Apache just to test things and run it as a separate server, not listening to port 80 but to some other port. There are lots of useful pointers to doing things like this in the Guide, the mod_perl home page will lead you there too. 73, Ged.
