This chapter describes how to obtain and install MySQL. A summary of
the procedure follows and later sections provide the details. If you
plan to upgrade an existing version of MySQL to a newer version rather
than install MySQL for the first time, see upgrade, for
information about upgrade procedures and about issues that you should
consider before upgrading.
1. *Determine whether your platform is supported.* Please note that
not all supported systems are equally suitable for running MySQL.
On some platforms it is much more robust and efficient than
others. See which-os, for details.
2. *Choose which distribution to install.* Several versions of MySQL
are available, and most are available in several distribution
formats. You can choose from pre-packaged distributions containing
binary (precompiled) programs or source code. When in doubt, use a
binary distribution. We also provide public access to our current
source tree for those who want to see our most recent developments
and help us test new code. To determine which version and type of
distribution you should use, see which-version.
3. *Download the distribution that you want to install.* For
instructions, see getting-mysql. To verify the integrity
of the distribution, use the instructions in
4. *Install the distribution.* To install MySQL from a binary
distribution, use the instructions in
quick-standard-installation. To install MySQL from a source
distribution or from the current development source tree, use the
instructions in installing-source.
If you encounter installation difficulties, see
operating-system-specific-notes, for information on solving
problems for particular platforms.
5. *Perform any necessary post-installation setup.* After installing
MySQL, read post-installation. This section contains
important information about making sure the MySQL server is
working properly. It also describes how to secure the initial
MySQL user accounts, _which have no passwords_ until you assign
passwords. The section applies whether you install MySQL using a
binary or source distribution.
6. If you want to run the MySQL benchmark scripts, Perl support for
MySQL must be available. See perl-support.
