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-
,
where VERSION
-OS
.tar.gz
is a
number (for example, VERSION
5.5.9
), 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 have previously installed MySQL using your operating system
native package management system, such as yum
or apt-get
, you may experience problems
installing using a native binary. Make sure your previous MySQL
previous installation has been removed entirely (using your
package management system), and that any additional files, such as
old versions of your data files, have also been removed. You
should also check the existence of configuration files such as
/etc/my.cnf
or the
/etc/mysql
directory have been deleted.
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.
Table 2.2. MySQL Installation Layout for Generic Unix/Linux Binary Package
Directory | Contents of Directory |
---|---|
bin | Client programs and the mysqld server |
data | Log files, databases |
docs | Manual in Info format |
man | Unix manual pages |
include | Include (header) files |
lib | Libraries |
scripts | mysql_install_db |
share | Miscellaneous support files, including error messages, sample configuration files, SQL for database installation |
sql-bench | Benchmarks |
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 2.11, “Installing MySQL from Source”.
To install and use a MySQL binary distribution, the basic command sequence looks like this:
shell>groupadd mysql
shell>useradd -r -g mysql mysql
shell>cd /usr/local
shell>tar zxvf
shell>/path/to/mysql-VERSION-OS
.tar.gzln -s
shell>full-path-to-mysql-VERSION-OS
mysqlcd mysql
shell>chown -R mysql .
shell>chgrp -R mysql .
shell>scripts/mysql_install_db --user=mysql
shell>chown -R root .
shell>chown -R mysql data
# Next command is optional shell>cp support-files/my-medium.cnf /etc/my.cnf
shell>bin/mysqld_safe --user=mysql &
# Next command is optional shell>cp support-files/mysql.server /etc/init.d/mysql.server
A more detailed version of the preceding description for installing a binary distribution follows.
This procedure assumes that you have root
(administrator) access to your system. Alternatively, you can
prefix each command using the sudo (Linux) or
pfexec (OpenSolaris) command.
The procedure does not set up any passwords for MySQL accounts. After following the procedure, proceed to Section 2.12, “Postinstallation Setup and Testing”.
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 mysql
shell>useradd -r -g mysql mysql
Because the user is required only for ownership purposes, not
login purposes, the useradd command uses the
-r
option to create a user that does not have
login permissions to your server host. Omit this option to permit
logins for the user (or if your useradd does
not support the option).
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
shell>/path/to/mysql-VERSION-OS
.tar.gzln -s
full-path-to-mysql-VERSION-OS
mysql
The tar command creates a directory named
mysql-
.
The VERSION
-OS
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 2.12, “Postinstallation Setup and Testing”.
The accounts that are listed in the MySQL grant tables initially have no passwords. After starting the server, you should set up passwords for them using the instructions in Section 2.12, “Postinstallation Setup and Testing”.
