Peter posted that CentOS comes with a build<\/a> of MySQL Enterprise. It should really be clarified that CentOS itself, comes with MySQL Community, as does Red Hat Enterprise Linux. On RHEL5\/CentOS5, you’ll see:
\n
\nmysql-5.0.22-2.2.el5_1.1
\nmysql-server-5.0.22-2.2.el5_1.1
\n<\/code>
\nThe above are the default packages that CentOS provides. However, what Peter really is referring to is the CentOSPlus Repository<\/a>, which by their own admittance is “not part of the upstream distribution and extend CentOS’s functionality at the expense of upstream compatibility. Enabling this repository makes CentOS different from upstream.”<\/em><\/p>\n

The idea behind providing Enterprise builds, largely came from RHBZ#230412: No src.rpm available for mysql<\/a>. Red Hat provides something called the Web Application Stacks product (RHWAS), in where they include MySQL Enterprise, amongst other software packages, and they charge for support (that differs from buying just a RHEL license). Max Spevack answers it pretty well<\/a>, as this is the response he came to, after talking to folk at MySQL.<\/p>\n

Its worth noting that CentOSPlus does not use Enterprise tarballs\/SRPMS, but use sources from the BitKeeper tree. Its worth noting, that at the time of this writing, CentOSPlus does not include Enterprise RPMs for CentOS 5, just CentOS 4. Its also worth noting that patches are being applied, that are out of tree, to the RPMs. A snippet from the RPM changelog (rpm -q --changelog <packagename><\/tt> if you must):
\n
\n* Mon Dec 24 2007 Johnny Hughes <johnny@centos.org> 5.0.54-1.el4.centos
\n- upgraded to the 5.0.54 Enterprise BK tree. Removed patches that are
\nalready incorporated into 5.0.54.<\/code>
\n
\n- added mysql-5.0.52-mysqldump-hang-33057.patch for mysql bug #33057<\/code>
\n
\n- added mysql-5.0.50-openssl-handshake-33050.patch fo mysql bug #33050<\/code>
\n
\n* Sun Dec 23 2007 Johnny Hughes <johnny@centos.org> 5.0.48-3.el4.centos
\n- modified the process of obtaining the Enterprise Sources to using bkf and
\ndownloading directly from the MySQL Enterprise BitKeeper tree.<\/code><\/p>\n

So, definitely interesting times. If you hit a bug, you might be wondering if its an upstream bug, or something that was provided by your packager. Of course, this is what is so great about the MySQL community – the ability to do just this! Currently, against 5.0.54, CentOSPlus is shipping 2 patches, with a few extra source packages that don’t come with regular tarballs. Will this number grow? Just remember, the “Enterprise” version you get in CentOSPlus is not<\/strong> “MySQL Enterprise”.<\/p>\n
