php and mysql on Redhat - Page cannot be displayed

emmahodd2

I have PHP and MySQL on Redhat. I have installed a RPM to connect the too.

PHP works fine. The problem is when i use a PHP page to access a mySQL database. The webpage just comes up 'The Page cannot be Displayed' even though the page is there!

Puzzling me this one.

FOLLOWUP :-
MySQL is running as I can create, edit tables etc. through the MySQL admin interface.

make sure you can run simple .php or .html pages.
.php pages without any sql connection i.e. simple echo commands.

PHP works fine by itself - ie. echo commands.

As soon as I add any references to mysql it comes up with this problem.

Please post some code so we can check if something is wrong ...

The problem is code independant.

if i put in test.php

echo "hello";

the page will run.

If i put

echo "hello";

$db = mysql_connect("localhost", "root");

I get the error 'Cannot find Server', can be seen here

It isn't even running the code.

Do you get a "document contains no data" error message if you try to request that page with e.g. Netscape or Mozilla ? If that is the case check the error log if there are any "segmentation fault" error messages in it. Might be some problem with the mysql support that causes apache to core dump.

One quick browse and Apache is seg faulting.

Must be mySQL causing it

but why, and how do I fix it are the two golden questions.

How does mySQL have to be configured with Apache?

stolzyboy

maybe you should try from square one and look at the install links i provided to get php/mysql running, do the mysql first, then do the php one

Hi,

which versions of php, apache, MySQL and glibc are installed. Which package did you install to "connect the too" ?

emmahodd2

the prob seemed to be the versions. upgraded to newest version of apache and it worked. I was using latest editions of mysql and php and they obviously didn't like old apache!!
