When you download MySQL Installer for the first time, a setup wizard guides you through the initial installation of MySQL products. As the following figure shows, the initial setup is a one-time activity in the overall process. MySQL Installer detects existing MySQL products installed on the host during its initial setup and adds them to the list of products to be managed.
MySQL Installer extracts configuration files (described later) to the hard drive of the host during the initial setup. Although MySQL Installer is a 32-bit application, it can install both 32-bit and 64-bit binaries.
The initial setup adds a link to the Start menu under thegroup. Click , , , to open MySQL Installer.
During the initial setup, you are prompted to select the MySQL products to be installed on the host. One alternative is to use a predetermined setup type that matches your setup requirements. By default, both GA and pre-release products are included in the download and installation with the Developer Default, Client only, and Full setup types. Select the Only install GA products option to restrict the product set to include GA products only when using these setup types.
Choosing one of the following setup types determines the initial installation only and does not limit your ability to install or update MySQL products for Windows later:
Developer Default: Install the following products that compliment application development with MySQL:
Server only: Only install the MySQL server. This setup type installs the general availability (GA) or development release server that you selected when you downloaded MySQL Installer. It uses the default installation and data paths.
Client only: Only install the most recent MySQL applications and MySQL connectors. This setup type is similar to the
Developer Defaulttype, except that it does not include MySQL server or the client programs typically bundled with the server, such as mysql or mysqladmin.
Full: Install all available MySQL products.
Custom: The custom setup type enables you to filter and select individual MySQL products from the MySQL Installer catalog.Note
For MySQL Server versions 8.0.20 (and earlier), 5.7, and 5.6, the account you use to run MySQL Installer may not have adequate permission to install the server data files and this can interrupt the installation because the
ExecSecureObjectsMSI action cannot be executed. To proceed, deselect the Server data files feature before attempting to install the server again. For help, see Product Features To Install).
The Server data files check box was removed from the feature tree for MySQL Server 8.0.21 (and higher).
Customsetup type to install:
A product or product version that is not available from the usual download locations. The catalog contains all product releases, including the other releases between pre-release (or development) and GA.
An instance of MySQL server using an alternative installation path, data path, or both. For instructions on how to adjust the paths, see Section 5.3.2, “Setting Alternative Server Paths with MySQL Installer”.
Two or more MySQL server versions on the same host at the same time (for example, 5.6, 5.7, and 8.0).
A specific combination of products and features not offered as a predetermine setup type. For example, you can install a single product, such as MySQL Workbench, instead of installing all client applications for Windows.
When the default installation or data folder (required by MySQL server) for a product to be installed already exists on the host, the wizard displays the Path Conflict step to identify each conflict and enable you to take action to avoid having files in the existing folder overwritten by the new installation. You see this step in the initial setup only when MySQL Installer detects a conflict.
To resolve the path conflict, do one of the following:
Select a product from the list to display the conflict options. A warning symbol indicates which path is in conflict. Use the browse button to choose a new path and then click.
Clickto choose a different setup type or product version, if applicable. The
Customsetup type enables you to select individual product versions.
Clickto ignore the conflict and overwrite files in the existing folder.
Delete the existing product. Click MySQL Installer dashboard.to stop the initial setup and close MySQL Installer. Open MySQL Installer again from the Start menu and delete the installed product from the host using the Delete operation from the
MySQL Installer uses entries in the
file to determine whether the prerequisite software for each
product is installed on the host. When the requirements check
fails, MySQL Installer displays the Check Requirements
step to help you update the host. Requirements are evaluated
each time you download a new product (or version) for
installation. The following figure identifies and describes the
key areas of this step.
Shows the current step in the initial setup. Steps in this list may change slightly depending on the products already installed on the host, the availability of prerequisite software, and the products to be installed on the host.
Lists all pending installation requirements by product and indicates the status as follows:
A blank space in the Status column means that MySQL Installer can attempt to download and install the required software for you.
The word Manual in the Status column means that you must satisfy the requirement manually. Select each product in the list to see its requirement details.
Describes the requirement in detail to assist you with each manual resolution. When possible, a download URL is provided. After you download and install the required software, clickto verify that the requirement has been met.
Provides the following set operations to proceed:
All MySQL Installer files are located within the
folders. The following table describes the files and folders
that define MySQL Installer as a standalone application.
Installed MySQL products are neither altered nor removed when you update or uninstall MySQL Installer.
