Connecting to MySQL 5 from PHP on Mac OSX Leopard

For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))

What is the difference between "localhost" and "127.0.0.1"? Everything, it seems, when you're trying to connect MySQL (and I have version 5.0.37 Community at the moment) running on Mac OSX - the latest Leopard release - with their PHP release including the MySQL drivers. It's PHP release 5.2.4.

In a nutshell:
mysql_connect("localhost","wellho","nottherealpassword");
FAILS with an error message:
Warning: mysql_connect() [function.mysql-connect]: Can't connect to local MySQL server through socket '/var/mysql/mysql.sock' (2) in /Library/WebServer/live_html/test/test.php on line 2

but:
mysql_connect("127.0.0.1","wellho","nottherealpassword");
works just fine.

Another gem ... to add to the loss of classic mode (serious issue for us FrameMaker users!) and the movement of configuration files. I have to admit this hasn't been the easiest of upgrades, and I wait to see whether I have more issues to find.

If you want to learn all about Apache httpd installation / configuration - and the PHP and MySQL elements too - see our LAMP deployment course. I'm the tutor and the "L" for Linux is close enough to the "M" for Mac OSX for it to be pretty damned close and very effective training. And I can and will show you how it works on my Mac too ;-)

This is a page archived from The Horse's Mouth at http://www.wellho.net/horse/ - the diary and writings of Graham Ellis. Every attempt was made to provide current information at the time the page was written, but things do move forward in our business - new software releases, price changes, new techniques. Please check back via our main site for current courses, prices, versions, etc - any mention of a price in "The Horse's Mouth" cannot be taken as an offer to supply at that price.
