2.2 Installing MySQL on Unix/Linux Using Generic Binaries

Oracle provides a set of binary distributions of MySQL. These include generic binary distributions in the form of compressed
tar files (files with a

.tar.gz

extension) for a number of platforms, and 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 2.1.2, “How to Get MySQL”.

MySQL compressed tar file binary distributions have names of the form

mysql-
VERSION
-[code]OS

.tar.gz[/code], where

VERSION

[/code] is a number (for example,

5.6.34

), and

OS

indicates the type of operating system for which the distribution is intended (for example,

pc-linux-i686

or

winx64

).

Warning
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 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 for configuration files such as

/etc/my.cnf

or the

/etc/mysql

directory and delete them.

For information about replacing third-party packages with official MySQL packages, see the related

Apt guide or
Yum guide.

Warning
MySQL has a dependency on the

libaio

library. Data directory initialization and subsequent server startup steps will fail if this library is not installed locally. If necessary, install it using the appropriate package manager. For example,
on Yum-based systems:

shell>

yum search libaio

# search for infoshell>

yum install libaio

# install library
Or, on APT-based systems:

shell>

apt-cache search libaio

# search for infoshell>

apt-get install libaio1

# install library
If you run into problems and need to file a bug report, please use the instructions in

Section 1.6, “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 2.3 MySQL Installation Layout for Generic Unix/Linux Binary Package
#这是mysql的目录结构

Directory	Contents of Directory
bin , scripts	mysqld server, client and utility programs
data	Log files, databases
docs	MySQL manual in Info format
man	Unix manual pages
include	Include (header) files
lib	Libraries
share	Miscellaneous support files, including error messages, sampleconfiguration 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. See

Section 2.9, “Installing MySQL from Source”.

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

#此段为本人翻译 便于小白查看 嘿嘿

shell>

groupadd mysql  #创建mysql组

shell>

useradd -r -g mysql -s /bin/false mysql #创建mysql用户

shell>

cd /usr/local #跳转到此目录 默认此目录为应用安装目录  可以自行选择

shell>

tar zxvf 
/path/to/mysql-VERSION-OS
.tar.gz #解压免编译安装包

shell>

ln -s 
full-path-to-mysql-VERSION-OS
 mysql# 创建快捷方式  可选操作

shell>

cd mysql #跳转到解压完毕的目录

shell>

chown -R mysql #将mysql目录拥有者更改为mysql用户

shell>

chgrp -R mysql

#将mysql目录组拥有者更改为mysql组

shell>

scripts/mysql_install_db --user=mysql#安装初始化数据库 包含mysql基础表 如mysql.user

shell>

bin/mysqld_safe --user=mysql & 后台启动mysql服务
 

# Next command is optionalshell>

cp support-files/mysql.server /etc/init.d/mysql.server#设置开机自启

Note
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.

Note
The procedure does not assign passwords to MySQL accounts. To do so, use the instructions in

Section 2.10.4, “Securing the Initial MySQL Accounts”.

As of MySQL 5.6.8,
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 to use for running
mysqld, 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 -s /bin/false mysql

Note
Because the user is required only for ownership
926a
purposes, not login purposes, the
useradd command uses the

-r

and

-s /bin/false

options to create a user that does not have login permissions to your server host. Omit these options if your
useradd does not support them.
