Hi all –
I encountered the same issue and this is how I solved the problem:
I have RHEL 4 x64 and it came with apache webserver (httpd-2.0.52-22.ent). It also came with PHP installed 4.3.9. I had already installed mysql 5.0.22 for my previous moonlighting project. All that I needed to do was to install wordpress to get it going.
However, I encounted the ‘ Your PHP installation appears to be missing the MySQL extension which is required’ problem. After investigating for a couple of hours I found that:
(1) mysql extention was not enabled in /etc/php.ini and
(2) the mysql.so was missing. This took me the longest to figure out. After searching around a bit I realised that my pre-packaged php server did not have the necessary libraries to connect to PHP. Hence I needed php-mysql-4.3.9-3.9 package (php-mysql-4.3.9-3.9.x86_64.rpm) which has mysql.so. However, this package has a dependency on mysql compatibility library MySQL-shared-compat-5.1.30-0.rhel4.x86_64.rpm. After installing these two (rpm -ivh <name>.rpm) I restarted the apache (apachectl -k restart). Thats it. It works now.
Happy blogging and installing.
Thanks –
Karthik
