MySQL 的官網(wǎng)下載地址：

在這個下載界面會有幾個版本的選擇。

1. MySQL Community Server 社區(qū)版本，開源免費，但不提供官方技術(shù)支持。
2. MySQL Enterprise Edition 企業(yè)版本，需付費，可以試用30天。
3. MySQL Cluster 集群版，開源免費。可將幾個MySQL Server封裝成一個Server。
4. MySQL Cluster CGE 高級集群版，需付費。
5. MySQL Workbench（GUI TOOL）一款專為MySQL設(shè)計的ER/數(shù)據(jù)庫建模工具。它是著名的數(shù)據(jù)庫設(shè)計工具DBDesigner4的繼任者。MySQL Workbench又分為兩個版本，分別是社區(qū)版（MySQL Workbench OSS）、商用版（MySQL Workbench SE）。

MySQL Community Server 是開源免費的，這也是我們通常用的MySQL的版本。根據(jù)不同的操作系統(tǒng)平臺細分為多個版本，下面我們以windows平臺為例來說明。

例如下載mysql 5.5.19的界面如下：

一般做后臺開發(fā)，我們就下載mysql-5.5.19-win32.msi。

例如下載mysql 5.1.60的界面如下：

一般做后臺開發(fā)，我們就下載mysql-essential-5.1.60-win32.msi 即可。

參考：

For MySQL 5.0, there are three installation packages to choose from when installing MySQL on Windows:

The Essentials Package: This package has a filename similar to mysql-essential-5.0.40-win32.msi and contains the minimum set of files needed to install MySQL on Windows, including the Configuration Wizard. This package does not include optional components such as the embedded server and benchmark suite.

The Complete Package: This package has a filename similar to mysql-5.0.40-win32.zip and contains all files needed for a complete Windows installation, including the Configuration Wizard. This package includes optional components such as the embedded server and benchmark suite.

The Noinstall Archive: This package has a filename similar to mysql-noinstall-5.0.40-win32.zip and contains all the files found in the Complete install package, with the exception of the Configuration Wizard. This package does not include an automated installer, and must be manually installed and configured.

The Essentials package is recommended for most users. It is provided as an .msi file for use with the Windows Installer. The Complete and Noinstall distributions are packaged as Zip archives. To use them, you must have a tool that can unpack .zip files.

Your choice of install package affects the installation process you must follow. If you choose to install either the Essentials or Complete install packages, see Section 2.4.8.2, “Installing MySQL with the Automated Installer”. If you choose to install MySQL from the Noinstall archive, see Section 2.4.8.5, “Installing MySQL from a Noinstall Zip Archive”.
