This section describes the MySQL Installer product catalog, the dashboard, and other actions related to product selection and upgrades.本节介绍MySQL安装程序的产品目录、仪表板以及与产品选择和升级相关的其他操作。
The product catalog stores the complete list of released MySQL products for Microsoft Windows that are available to download from MySQL Downloads. 产品目录存储了适用于Microsoft Windows的已发布MySQL产品的完整列表，这些产品可从MySQL下载中下载。By default, and when an Internet connection is present, MySQL Installer attempts to update the catalog at startup every seven days. You can also update the catalog manually from the dashboard (described later).默认情况下，当存在Internet连接时，MySQL安装程序会尝试每七天在启动时更新一次目录。您也可以从仪表板手动更新目录（稍后介绍）。
An up-to-date catalog performs the following actions:最新的目录执行以下操作：
Populates the Available Products pane of the Select Products page.填充“选择产品”页面的“可用产品”窗格。This step appears when you select:当您选择以下内容时，会出现此步骤：The初始设置期间的Customsetup type during the initial setup.Custom设置类型。The Add operation from the dashboard.面板中的“添加”操作。
Identifies when product updates are available for the installed products listed in the dashboard.标识仪表板中列出的已安装产品何时可以使用产品更新。
The catalog includes all development releases (Pre-Release), general releases (Current GA), and minor releases (Other Releases). Products in the catalog will vary somewhat, depending on the MySQL Installer release that you download.目录包括所有开发版本（预发布版）、常规版本（当前GA）和次要版本（其他版本）。目录中的产品会有所不同，具体取决于您下载的MySQL安装程序版本。
The MySQL Installer dashboard is the default view that you see when you start MySQL Installer after the initial setup finishes. MySQL安装程序面板是初始安装完成后启动MySQL安装程序时看到的默认视图。If you closed MySQL Installer before the setup was finished, MySQL Installer resumes the initial setup before it displays the dashboard.如果在安装完成之前关闭了MySQL安装程序，则MySQL安装程序将在显示面板之前恢复初始安装。
Products covered under Oracle Lifetime Sustaining Support, if installed, may appear in the dashboard. These products, such as MySQL for Excel and MySQL Notifier, can be modified or removed only.“Oracle终身持续支持”涵盖的产品（如果已安装）可能会显示在仪表板中。这些产品，如MySQL for Excel和MySQL Notifier，只能修改或删除。

Important server upgrade conditions:重要的服务器升级条件：
MySQL Installer does not permit server upgrades between major release versions or minor release versions, but does permit upgrades within a release series, such as an upgrade from 5.7.18 to 5.7.19.MySQL安装程序不允许在主要发布版本或次要发布版本之间进行服务器升级，但允许在发布系列内进行升级，例如从5.7.18升级到5.7.19。Upgrades between milestone releases (or from a milestone release to a GA release) are not supported. Significant development changes take place in milestone releases and you may encounter compatibility issues or problems starting the server.不支持在里程碑版本之间升级（或从里程碑版本升级到GA版本）。里程碑版本中会发生重大的开发更改，您可能会遇到兼容性问题或启动服务器的问题。For upgrades to MySQL 8.0.16 server and higher, a check box enables you to skip the upgrade check and process for system tables, while checking and processing data dictionary tables normally.对于MySQL 8.0.16服务器及更高版本的升级，复选框允许您跳过系统表的升级检查和处理，同时正常检查和处理数据字典表。MySQL Installer does not prompt you with the check box when the previous server upgrade was skipped or when the server was configured as a sandbox InnoDB Cluster.当跳过上一次服务器升级或将服务器配置为沙箱InnoDBCluster时，MySQL安装程序不会提示您使用复选框。This behavior represents a change in how MySQL Server performs an upgrade (see Section 2.11.3, “What the MySQL Upgrade Process Upgrades”) and it alters the sequence of steps that MySQL Installer applies to the configuration process.此行为表示MySQL Server执行升级的方式发生了变化（请参阅第2.11.3节，“MySQL升级过程升级的内容”），并改变了MySQL安装程序应用于配置过程的步骤顺序。If you select Skip system tables upgrade check and process. (Not recommended), MySQL Installer starts the upgraded server with the如果选择“跳过系统表”，请检查并处理升级。（不推荐），MySQL安装程序使用--upgrade=MINIMALserver option, which upgrades the data dictionary only.--upgrade=MINIMAL服务器选项启动升级后的服务器，该选项仅升级数据字典。If you stop and then restart the server without the如果在不使用--upgrade=MINIMALoption, the server upgrades the system tables automatically, if needed.--upgrade=MINIMAL选项的情况下停止并重新启动服务器，则服务器会根据需要自动升级系统表。The following information appears in the Log tab and log file after the upgrade configuration (with system tables skipped) is complete:升级配置（跳过系统表）完成后，“日志”选项卡和日志文件中将显示以下信息：WARNING: The system tables upgrade was skipped after upgrading MySQL Server. The server will be started now with the --upgrade=MINIMAL option, but then each time the server is started it will attempt to upgrade the system tables, unless you modify the Windows service (command line) to add --upgrade=MINIMAL to bypass the upgrade. FOR THE BEST RESULTS: Run mysqld.exe --upgrade=FORCE on the command line to upgrade the system tables manually.
To choose a new server version:要选择新的服务器版本，请执行以下操作：
Click Upgrade.单击“升级”。Confirm that the check box next to product name in the Upgradeable Products pane has a check mark. Deselect the products that you do not intend to upgrade at this time.确认“可升级的产品”窗格中产品名称旁边的复选框有复选标记。取消选择此时不打算升级的产品。Note注意For server milestone releases in the same release series, MySQL Installer deselects the server upgrade and displays a warning to indicate that the upgrade is not supported, identifies the risks of continuing, and provides a summary of the steps to perform a logical upgrade manually.对于同一版本系列中的服务器里程碑版本，MySQL安装程序将取消选择服务器升级并显示一条警告，指示不支持升级，确定继续升级的风险，并提供手动执行逻辑升级的步骤摘要。You can reselect server upgrade at your own risk. For instructions on how to perform a logical upgrade with a milestone release, see Logical Upgrade.您可以重新选择服务器升级，风险自负。有关如何使用里程碑版本执行逻辑升级的说明，请参阅逻辑升级。Click a product in the list to highlight it.单击列表中的产品以将其高亮显示。This action populates the Upgradeable Versions pane with the details of each available version for the selected product: version number, published date, and a此操作将使用所选产品的每个可用版本的详细信息填充“可升级版本”窗格：版本号、发布日期，以及打开该版本的发行说明的“更改”链接。Changeslink to open the release notes for that version.
To remove a local MySQL server:要删除本地MySQL服务器，请执行以下操作：
Determine whether the local data directory should be removed.确定是否应删除本地数据目录。If you retain the data directory, another server installation can reuse the data. This option is enabled by default (removes the data directory).如果保留数据目录，则另一个服务器安装可以重用数据。默认情况下会启用此选项（删除数据目录）。Click to begin uninstalling the local server. Note that all products that you selected to remove are also uninstalled at this time.单击“执行”开始卸载本地服务器。请注意，此时也会卸载您选择删除的所有产品。(Optional) Click the Log tab to display the current actions performed by MySQL Installer.（可选）单击“日志”选项卡以显示MySQL安装程序执行的当前操作。
MySQL Installer remains installed on your computer, and like other software, MySQL Installer can be upgraded from the previous version. In some cases, other MySQL software may require that you upgrade MySQL Installer for compatibility. MySQL安装程序仍然安装在您的计算机上，与其他软件一样，MySQL安装程序可以从以前的版本升级。在某些情况下，其他MySQL软件可能需要升级MySQL安装程序以实现兼容性。This section describes how to identify the current version of MySQL Installer and how to upgrade MySQL Installer manually.本节介绍如何识别MySQL安装程序的当前版本以及如何手动升级MySQL安装程序。
