The MySQL team is fixing critical bugs (if any are found) for customers who are paying for extended maintenance. Until now, builds with critical bugs fixed have also been made available to the community, but there is no promise this practice will be continued. I recommend to base any new installation on a post-5.0 version of MYSQL which is declared GA (generally available, production quality). Currently, for this you can choose between 5.1 and 5.5. While 5.5 is quite new in GA status, nonetheless the reactions (both internal and external) are very positive. Especially if you want to use InnoDB as your table engine in higher load situations, you should profit very much from several improvements contained in 5.5. So IMO 5.0 is a no for new installations, 5.1 could be considered, but 5.5 is to be preferred. 2.the my.cnf should i configure or where i can find some information? Some sample configuration files are contained in the distribution. You should create your own by looking at these samples, combining their parts according to your needs and ressources, and then fine-tuning it based on the results of tests, measurements, and real-life use data.

Re: centos server's mysql version's problem
I think the version CentOS (5.5) wants to use is 5.0.77-log. I don't think CentOS will be updating the repository 5.5 uses for updates to any later version of mysql. I just completed two MySQL 5.5 installs on some RHEL machines by using the remi repository. I followed this guide here: http://www.if-not-true-then-false.com/2010/install-mysql-on-fedora-centos-red-hat-rhel/ http://www.if-not-true-then-false.com/2010/install-mysql-on-fedora-centos-red-hat-rhel/Install went well, server runs great. I'd suggest going with 5.5.

RE: centos server's mysql version's problem
Just so I am clear here, you have 8 different DB servers hosting the same data that is being accessed and potentially modified simultaneously? You may want to consider the replication issues involved in that sort of arrangement with mysql. Aside from that, I am currently hosting an 18gb mysql database that is passing roughly 6gb/hr without any issue utilizing a single Dell R710 and mysql 5.0.77. Your mileage may differ based on the low end hardware/storage that you plan to use, the number of writes and the amount of data that you can cache in memory.

Re: centos server's mysql version's problem
The only 5.1 version I tried was percona's. I only tested it in development. Can't speak for MySQL's version. 5.5 is GA now, its supposed to have many improvements for mulitiprocessor machines over 5.0 and 5.1. This will be my first production install of 5.5, real traffic has not hit yet, but it performed well in testing. Our 5.0 installs are handling about 25gb of data and 1200qps during peak hours.
