 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.
