MySQL is available on a number of operating systems and platforms. For information about those platforms that are officially supported, see http://www.mysql.com/support/supportedplatforms/database.html on the MySQL Web site.
When preparing to install MySQL, you should decide which version to use, and which distribution format (binary or source) to use for the installation.
First, decide if you want to install a development release or a GA release. Development releases have the newest features, but are not recommended for production use. GA (General Availability) releases, also called production or stable releases, are meant for production use. We recommend to use the most recent GA release.
The naming scheme in MySQL 5.6 uses release names that consist of three numbers and a suffix; for example, mysql-5.6.1-m1. The numbers within the release name are interpreted as follows:
The first number (5) is the major version and describes the file format. All MySQL 5 releases have the same file format.
The second number (6) is the release level. Taken together, the major version and release level constitute the release series number.
The third number (1) is the version number within the release series. This is incremented for each new release. Usually you want the latest version for the series you have chosen.
For each minor update, the last number in the version string is incremented. When there are major new features or minor incompatibilities with previous versions, the second number in the version string is incremented. When the file format changes, the first number is increased.
Release names can also include a suffix that indicates the stability level of the release. Releases within a series progress through a set of suffixes to indicate how the stability level improves. The possible suffixes are:
If there is no suffix, it indicates that the release is a General Availability (GA) or Production release. GA releases are stable, having successfully passed through all earlier release stages and are believed to be reliable, free of serious bugs, and suitable for use in production systems. Only critical bugfixes are applied to the release.
mN (for example, m1, m2, m3, ...) indicate a milestone number. MySQL development uses a milestone model, in which each milestone proceeds through a small number of versions with a tight focus on a small subset of thoroughly tested features. Following the releases for one milestone, development proceeds with another small number of releases that focuses on the next small set of features, also thoroughly tested. Features within milestone releases may be considered to be of pre-production quality.
rc indicates a Release Candidate. Release candidates are believed to be stable, having passed all of MySQL's internal testing, and with all known fatal runtime bugs fixed. However, the release has not been in widespread use long enough to know for sure that all bugs have been identified. Only minor fixes are added.
Once you've chosen which MySQL version to install, you need to decide which distribution to install for your operating system. For most use cases, a binary distribution is the right choice. Binary distributions are available in native format for many platforms, such as RPM packages for Linux, or DMG packages for OS X. Distributions are also available in more generic formats such as Zip archives or compressed tar files. On Windows, you can use the MySQL Installer to install a binary distribution.
Under some circumstances, you may be better off installing MySQL from a source distribution:
You want to install MySQL at some explicit location. The standard binary distributions are ready to run at any installation location, but you might require even more flexibility to place MySQL components where you want.
You want to configure mysqld to ensure that features are available that might not be included in the standard binary distributions. Here is a list of the most common extra options that you may want to use to ensure feature availability:
For additional information, see Section 2.9.4, “MySQL Source-Configuration Options”.
You want to configure mysqld without some features that are included in the standard binary distributions. For example, distributions normally are compiled with support for all character sets. If you want a smaller MySQL server, you can recompile it with support for only the character sets you need.
You want to use the latest sources from one of the Git repositories to have access to all current bugfixes. For example, if you have found a bug and reported it to the MySQL development team, the bugfix is committed to the source repository and you can access it there. The bugfix does not appear in a release until a release actually is issued.
You want to read (or modify) the C and C++ code that makes up MySQL. For this purpose, you should get a source distribution.
Source distributions contain more tests and examples than binary distributions.
