* I am trying to Install on Red Hat EL 4 and have MySQL 4.1.22 running.
* When I start the install for WordPress I get the following message:
Your PHP
installation appears to be missing the MySQL extension which is required by WordPress.
* I have done an up2date php* and mysql*. Anyone have any idea what package I might
be missing?
* I did not have this problem in Fedora but, this is my wifes business machine
so I have to keep Red Hat on it.

* This might do it: run phpinfo to see where your php.ini file is. Make a plain
text file and call it phpinfo.php and put just this line in it:
* ``
* then put the file in the root of your server, and then go to that file with your
web browser. Find ‘Loaded Configuration File’. This will tell you the php.ini
that is being used.
* and uncomment this line and remove the preceding semicolon:
* `extension=php_mysql.dll`

* Thanks songdogtech, did as you suggested and have now proceeded to another problem.
* Now the message is:(pasting in the view source)
* WordPress › Error
Error establishing
a database connection
This either means that the username and password
information in your `wp-config.php` file is incorrect or we can’t contact the
database server at `localhost`. This could mean your host’s database server is
down.
- Are you sure you have the correct username and password?
- Are you sure that you have typed the correct hostname?
- Are you sure that the database server is running?
*
If you’re unsure what these terms mean you should probably contact your host.
If you still need help you can always visit the [WordPress Support Forums](http://wordpress.org/support/).
* MySQL is running and the database name, username and password are correct in
the config file. Scratches head and mumbles.
