Hi folks.
I've got MySQL running on a W2K dev box and want to run it on a production Linux box. Being new to Linux, I'm wondering what's the difference between the version of MySQL that ships with a Linux distro and downloading it from the MySQL website.
By way of example:
The SuSE website states that 9.1 Professional 64bit (will be running on an Opteron box) will ship with MySQL 4.0.18. They list the file path on DVD as "/suse/x86_64/mysql-4.0.18-25.x86_64.rpm": it's 17.64MB in size. The MySQL website lists the file as "MySQL-server-4.0.18-0.x86_64.rpm": it's 9.6MB in size.
What's the difference between them? Should I use the SuSE version or download from the MySQL site? Does MySQL (the company) supply the RPMs to RH, SuSE, etc to include in their distros or do the distro companies build the RPMs themselves?
MySQL is an open-source product. This means anybody can build and package a binary. MySQL AB does it, but so do the distributions like SuSE. For a low-cocurrency application, they are pretty much the same. However, a different build might make a huge difference in stability when the concurrency goes up. I have not yet research the AMD 64 binaries very much, so I cannot say which one is better. In the past, the MySQL team has put a lot of effort into making sure their binaries are absolutely the best on x86 Linux, and did a good job for other platforms. Based on what I've seen with the latest x86 binaries that came from MySQL AB, it appears to me that things have been slipping through the cracks a bit. So for x86, you might actually be better off with the SuSE binary. My uneducated guess about AMD 64 is that they would be about the same in both cases. If this is an issue of concern, try both and see which one performs better.
