How to configure MySql support?

When I try to use phpMyAdmin, I get an error:

"Cannot load mysql extension. Please check your PHP configuration."

There's a link in the error that points to http://us.php.net/mysql,
which says:

Use the --with-mysql[=DIR] configure option to include MySQL support.

But in the above package list, it shows "php5-mysql" is already
installed. Do I need to add this module to PHP? How?

Can someone please help me understand how to configure PHP with MySql
support?

Many thanks.

First of all, what does phpinfo() say about MySQL support? It's the
only authoritative answer.

I've snipped out some of the irrelevant packages. Note you have two copies
of PHP installed -- PHP4 and PHP5. You only have the MySQL extension
installed for PHP5, not PHP4. So if your script is running in a PHP4
environment, then the MySQL functions will not work.

I'd recommend removing php4-common and libapache2-mod-php4, and then
installing libapache2-mod-php5 if such a beast exists. Then try.

Great! Thanks for the tip. I've been trying to build a Debian LAMP server with
Samba and phpMyAdmin. I think I've got everything completed except the PHP
configuration. Apparently, PHP5 does not come with Debian Etch by default, and
PHP does not come with MySql support by default.

Debian is great, but all the install/configure tasks are not well documented as
much is distro-specific. But I did get Apache and Samba working. MySql appears
to be installed by default.

Really?

What sources have you got configured for packages? Are they all "stable"?
If so, add some "testing" sources in, and see if PHP5 is available for
install.

Debian is notorious for including fairly old versions of packages in its
"stable" branch. The "testing" branch has a lot more polish and stability
than its name gives it credit for, and is perfectly suitable for a
production server.

Try:
apt-get install apache2 libapache2-mod-php5 php5-cli php5-common php5-cgi

After using 'dpkg -r' and 'dpkg --purge', I ended up with this

bubba [/root] # dpkg -l | grep php
ii libapache-mod-php5 5.2.0-8+etch4
ii php5-common 5.2.0-8+etch4
ii php5-gd 5.2.0-8+etch4
ii php5-mcrypt 5.2.0-8+etch4
ii php5-mysql 5.2.0-8+etch4
ii phpmyadmin 2.9.1.1-3

There is a libapache2-mod-php5, but not sure if I need this:
http://packages.debian.org/unstable/...ache2-mod-php5

How do I add php5 to apache? If I issue the a2enmod command, I get a list of
module names that I could enable - the problem is I don't see php5 in the list.

See which version of Apache you are using. Apache 1.3 and Apache 2.x are
both fairly common -- Debian provides packages of each. (Most distros do.)

If you're running Apache 1.x, then use libapache-mod-php5;
if you're running Apache 2.x, then use libapache2-mod-php5.

If you seem to have both Apache 1.3 *and* Apache 2.x installed, then
uninstall one of them -- you'll only end up confusing yourself!

================================================== =

The problems now are:

-- blank page when accessing phpinfo.php
I tried adding 'AddType application/x-httpd-php .php' to my apache2.conf file
(and restarting apache), but no luck.
Do I have to recompile apache?

--Error when trying to access phpMyAdmin:
Error: 'The configuration file now needs a secret passphrase (blowfish_secret).'
I tried modifying config.inc.php by uncommenting this line:
$cfg['Servers'][$i]['auth_type'] = 'cookie';
but no luck.

Don't I need some mysql apache module loaded?
How do I tell apache2 to load a module?

got it working:

myserver [/etc/phpmyadmin] # vi config.inc.php
<?php
$i = 0;
$i++;
$cfg['Servers'][$i]['host'] = 'localhost'; // MySQL hostname or IP address
$cfg['Servers'][$i]['port'] = ''; // MySQL port (leave blank for
default port)
$cfg['Servers'][$i]['auth_type'] = 'http'; // Authentication method: config,
http, or cookie
$cfg['Servers'][$i]['user'] = 'root'; // MySQL user
$cfg['Servers'][$i]['password'] = ''; // MySQL password
?>

myserver [/usr/share/phpmyadmin] # vi phpinfo.php
<?php
phpinfo();
?>

For some reason the default phpinfo.php does not work - just returns a blank
page.

Getting the correct packages installed was half the battle... understanding the
Debian packaging system (apt, aptitude, dpkg, dselect) and knowing how to
configure everything with all the Debian Etch platform-specific peculiarities...
all without documentation.
