Chapter 2 Installing and Upgrading MySQL第2章：安装和升级MySQL

Determine whether MySQL runs and is supported on your platform.确定您的平台是否运行并支持MySQL。

Please note that not all platforms are equally suitable for running MySQL, and that not all platforms on which MySQL is known to run are officially supported by Oracle Corporation. 请注意，并非所有平台都同样适合运行MySQL，而且并非所有已知运行MySQL的平台都得到Oracle Corporation的正式支持。For information about those platforms that are officially supported, see https://www.mysql.com/support/supportedplatforms/database.html on the MySQL website.有关官方支持的平台的信息，请参阅MySQL网站上的https://www.mysql.com/support/supportedplatforms/database.html。

Choose which distribution to install.选择要安装的发行版。

Several versions of MySQL are available, and most are available in several distribution formats. MySQL有几个版本，大多数版本都有几种发行格式。You can choose from pre-packaged distributions containing binary (precompiled) programs or source code. 您可以从包含二进制（预编译）程序或源代码的预打包发行版中进行选择。When in doubt, use a binary distribution. 如有疑问，请使用二进制分布。Oracle also provides access to the MySQL source code for those who want to see recent developments and test new code. Oracle还为那些希望查看最新开发和测试新代码的人提供了对MySQL源代码的访问。To determine which version and type of distribution you should use, see Section 2.1.2, “Which MySQL Version and Distribution to Install”.要确定应该使用哪个版本和类型的发行版，请参阅第2.1.2节，“安装哪个MySQL版本和发行版”。

Download the distribution that you want to install.下载要安装的发行版。

For instructions, see Section 2.1.3, “How to Get MySQL”. 有关说明，请参阅第2.1.3节，“如何获取MySQL”。To verify the integrity of the distribution, use the instructions in Section 2.1.4, “Verifying Package Integrity Using MD5 Checksums or GnuPG”.要验证分发的完整性，请使用第2.1.4节，“使用MD5校验和或GnuPG验证包完整性”中的说明。

Install the distribution.安装配线架。

To install MySQL from a binary distribution, use the instructions in Section 2.2, “Installing MySQL on Unix/Linux Using Generic Binaries”. 要从二进制发行版安装MySQL，请使用第2.2节，“使用通用二进制文件在Unix/Linux上安装MySQL”中的说明。Alternatively, use the Secure Deployment Guide, which provides procedures for deploying a generic binary distribution of MySQL Enterprise Edition Server with features for managing the security of your MySQL installation.或者，使用《安全部署指南》，该指南提供了部署MySQL企业版服务器的通用二进制发行版的过程，该发行版具有管理MySQL安装安全性的功能。

To install MySQL from a source distribution or from the current development source tree, use the instructions in Section 2.9, “Installing MySQL from Source”.要从源发行版或当前开发源代码树安装MySQL，请使用第2.9节，“从源代码安装MySQL”中的说明。

Perform any necessary postinstallation setup.执行任何必要的安装后设置。

After installing MySQL, see Section 2.10, “Postinstallation Setup and Testing” for information about making sure the MySQL server is working properly. 安装MySQL后，请参阅第2.10节，“安装后设置和测试”，了解有关确保MySQL服务器正常工作的信息。Also refer to the information provided in Section 2.10.4, “Securing the Initial MySQL Account”. 另请参阅第2.10.4节，“保护初始MySQL帐户”中提供的信息。This section describes how to secure the initial MySQL root user account, which has no password until you assign one. 本节介绍如何保护初始MySQLroot用户帐户的安全，该帐户在分配密码之前没有密码。The section applies whether you install MySQL using a binary or source distribution.本节适用于使用二进制或源发行版安装MySQL。

If you want to run the MySQL benchmark scripts, Perl support for MySQL must be available. 如果要运行MySQL基准脚本，必须提供对MySQL的Perl支持。See Section 2.13, “Perl Installation Notes”.请参阅第2.13节，“Perl安装说明”。
