Oracle provides a set of binary distributions of MySQL. These include binary distributions in the form of compressed tar files (files with a .tar.gz extension) for a number of platforms, as well as binaries in platform-specific package formats for selected platforms.

This section covers the installation of MySQL from a compressed tar file binary distribution. For other platform-specific package formats, see the other platform-specific sections. For example, for Windows distributions, see Section 2.3, "Installing MySQL on Microsoft Windows".

To obtain MySQL, see Section 2.1.3, "How to Get MySQL".

MySQL compressed tar file binary distributions have names of the form mysql-VERSION-OS.tar.gz, where VERSION is a number (for example, 5.6.13), and OS indicates the type of operating system for which the distribution is intended (for example, pc-linux-i686 or winx64).

To install MySQL from a compressed tar file binary distribution, your system must have GNU gunzip to uncompress the distribution and a reasonable tar to unpack it. If your tar program supports the z option, it can both uncompress and unpack the file.

GNU tar is known to work. The standard tar provided with some operating systems is not able to unpack the long file names in the MySQL distribution. You should download and install GNU tar, or if available, use a preinstalled version of GNU tar. Usually this is available as gnutar, gtar, or as tar within a GNU or Free Software directory, such as /usr/sfw/bin or /usr/local/bin. GNU tar is available from http://www.gnu.org/software/tar/.

If you run into problems and need to file a bug report, please use the instructions in Section 1.7, "How to Report Bugs or Problems".

On Unix, to install a compressed tar file binary distribution, unpack it at the installation location you choose (typically /usr/local/mysql). This creates the directories shown in the following table.

Debug versions of the mysqld binary are available as mysqld-debug. To compile your own debug version of MySQL from a source distribution, use the appropriate configuration options to enable debugging support. For more information on compiling from source, see Section 2.9, "Installing MySQL from Source".

To install and use a MySQL binary distribution, the basic command sequence looks like this:

shell> groupadd
        mysqlshell> useradd -r -g mysql mysqlshell> cd /usr/localshell> tar zxvf /path/to/mysql-VERSION-OS.tar.gzshell> ln -s full-path-to-mysql-VERSION-OS mysqlshell> cd mysqlshell> chown -R mysql
        .shell> chgrp -R mysql .shell> scripts/mysql_install_db --user=mysqlshell> chown -R root .shell> chown -R
        mysql datashell> bin/mysqld_safe --user=mysql
        &# Next command is optionalshell> cp
        support-files/mysql.server /etc/init.d/mysql.server

mysql_install_db creates a default option file named my.cnf in the base installation directory. This file is created from a template included in the distribution package named my-default.cnf. For more information, see Section 5.1.2.2, "Using a Sample Default Server Configuration File".

A more detailed version of the preceding description for installing a binary distribution follows.

Create a mysql User and Group

If your system does not already have a user and group for mysqld to run as, you may need to create one. The following commands add the mysql group and the mysql user. You might want to call the user and group something else instead of mysql. If so, substitute the appropriate name in the following instructions. The syntax for useradd and groupadd may differ slightly on different versions of Unix, or they may have different names such as adduser and addgroup.

shell> groupadd
        mysqlshell> useradd -r -g mysql mysql

Obtain and Unpack the Distribution

Pick the directory under which you want to unpack the distribution and change location into it. The example here unpacks the distribution under /usr/local. The instructions, therefore, assume that you have permission to create files and directories in /usr/local. If that directory is protected, you must perform the installation as root.

shell> cd /usr/local

Obtain a distribution file using the instructions in Section 2.1.3, "How to Get MySQL". For a given release, binary distributions for all platforms are built from the same MySQL source distribution.

Unpack the distribution, which creates the installation directory. Then create a symbolic link to that directory. tar can uncompress and unpack the distribution if it has z option support:

shell> tar zxvf /path/to/mysql-VERSION-OS.tar.gzshell> ln -s full-path-to-mysql-VERSION-OS mysql

The tar command creates a directory named mysql-VERSION-OS. The ln command makes a symbolic link to that directory. This enables you to refer more easily to the installation directory as /usr/local/mysql.

If your tar does not have z option support, use gunzip to unpack the distribution and tar to unpack it. Replace the preceding tar command with the following alternative command to uncompress and extract the distribution:

shell> gunzip < /path/to/mysql-VERSION-OS.tar.gz
        | tar xvf -

Perform Postinstallation Setup

The remainder of the installation process involves setting up the configuration file, creating the core databases, and starting the MySQL server. For instructions, see Section 2.10, "Postinstallation Setup and Testing".
