MySQL Installer is a standalone application designed to ease the complexity of installing and configuring MySQL products that run on Microsoft Windows. It supports the following MySQL products:MySQL安装程序是一个独立的应用程序，旨在减轻安装和配置在Microsoft Windows上运行的MySQL产品的复杂性。它支持以下MySQL产品：
MySQL Servers
MySQL Installer can install and manage multiple, separate MySQL server instances on the same host at the same time. MySQL安装程序可以同时在同一主机上安装和管理多个独立的MySQL服务器实例。For example, MySQL Installer can install, configure, and upgrade a separate instance of MySQL 5.6, MySQL 5.7, and MySQL 8.0 on the same host. 例如，MySQL安装程序可以在同一主机上安装、配置和升级MySQL 5.6、MySQL 5.7和MySQL 8.0的单独实例。MySQL Installer does not permit server upgrades between major and minor version numbers, but does permit upgrades within a release series (such as 8.0.21 to 8.0.22).MySQL安装程序不允许在主要版本号和次要版本号之间进行服务器升级，但允许在发布系列（如8.0.21到8.0.22）内进行升级。
MySQL Installer cannot install both Community and Commercial releases of MySQL server on the same host. MySQL安装程序无法在同一主机上同时安装社区版和商业版MySQL服务器。If you require both releases on the same host, consider using the ZIP archive distribution to install one of the releases.如果需要在同一主机上同时安装两个版本，请考虑使用ZIP归档分发版来安装其中一个版本。

An internet connection is required to download a manifest containing metadata for the latest MySQL products that are not part of a full bundle. 下载包含非完整捆绑包中最新MySQL产品元数据的清单时，需要连接互联网。MySQL Installer attempts to download the manifest when you start the application for the first time and then periodically in configurable intervals (see MySQL Installer options). 当您第一次启动应用程序时，MySQL安装程序会尝试下载清单，然后以可配置的间隔定期下载（请参阅MySQL安装程序选项）。Alternatively, you can retrieve an updated manifest manually by clicking in the MySQL Installer dashboard.或者，您可以通过单击MySQL安装程序面板中的目录手动检索更新的清单。
If the first-time or subsequent manifest download is unsuccessful, an error is logged and you may have limited access to MySQL products during your session. 如果第一次或随后的清单下载不成功，则会记录一个错误，并且您可能在会话期间对MySQL产品的访问权限有限。MySQL Installer attempts to download the manifest with each startup until the initial manifest structure is updated. MySQL安装程序尝试在每次启动时下载清单，直到更新初始清单结构。For help finding a product, see Locating Products to Install.有关查找产品的帮助，请参阅定位要安装的产品。
