MySQL Installer handles the initial configuration of the MySQL server. For example:
It creates the configuration file (
my.ini) that is used to configure the MySQL server. The values written to this file are influenced by choices you make during the installation process. Some definitions are host dependent. For example, query_cache is enabled if the host has fewer than three cores.Note
Query cache was deprecated in MySQL 5.7 and removed in MySQL 8.0 (and later).
By default, a Windows service for the MySQL server is added.
Provides default installation and data paths for MySQL server. For instructions on how to change the default paths, see Section 188.8.131.52, “Setting Alternative Server Paths with MySQL Installer”.
It can optionally create MySQL server user accounts with configurable permissions based on general roles, such as DB Administrator, DB Designer, and Backup Admin. It optionally creates a Windows user named
MysqlSyswith limited privileges, which would then run the MySQL Server.
User accounts may also be added and configured in MySQL Workbench.
Checking Show Advanced Options allows additional Logging Options to be set. This includes defining custom file paths for the error log, general log, slow query log (including the configuration of seconds it requires to execute a query), and the binary log.
During the configuration process, clickto proceed to the next step or to return to the previous step. Click at the final step to apply the server configuration.
The sections that follow describe the server configuration options that apply to MySQL server on Windows. The server version you installed will determine which steps and options you can configure.
Server Configuration Type
Choose the MySQL server configuration type that describes your setup. This setting defines the amount of system resources (memory) that will be assigned to your MySQL server instance.
Development: A machine that will host many other applications, and typically this is your personal workstation. This option configures MySQL to use the least amount of memory.
Server: Several other applications will be running on this machine, such as a web server. This option configures MySQL to use a medium amount of memory.
Dedicated: A machine that is dedicated to running the MySQL server. Because no other major applications will run on this server, such as a web server, this option configures MySQL to use the majority of available memory.
Connectivity options control how the connection to MySQL is made. Options include:
TCP/IP: You may enable TCP/IP Networking here as otherwise only local host connections are allowed. Also define the Port Number and whether to open the firewall port for network access. If the port number is in use already, you will see the information icon () next to the default value and is disabled until you provide a new port number.
Named Pipe: Enable and define the pipe name, similar to using the
Shared Memory: Enable and then define the memory name, similar to using the
Check Show Advanced Options to set additional logging options in a later step. This includes defining custom file paths for the error log, general log, slow query log (including the configuration of seconds it requires to execute a query), and the binary log.
MySQL Enterprise Firewall (Commercial Edition only)
The Enable Enterprise Firewall check box is selected by default. For post-installation instructions, see MySQL Enterprise Firewall.
Root Account Password
Assigning a root password is required and you will be asked for it when performing other MySQL Installer operations. Password strength is evaluated when you repeat the password in the box provided. For descriptive information regarding password requirements or status, move your mouse pointer over the information icon () when it appears.
MySQL User Accounts
Optionally, you can create additional MySQL user accounts with predefined user roles. Each predefined role, such as DB Admin, are configured with their own set of privileges. For example, the DB Admin role has more privileges than the DB Designer role. Click the Role drop-down list for a description of each role.Note
If the MySQL server is installed, then you must also enter the current root password.
On the Windows platform, MySQL server can run as a named service managed by the operating system and be configured to start up automatically when Windows starts. Alternatively, you can configure MySQL server to run as an executable program that requires manual configuration.
Configure MySQL server as a Windows service (Selected by default.)
When the default configuration option is selected, you can also select the following:
Start the MySQL Server at System Startup
When selected (default), the service startup type is set to Automatic; otherwise, the startup type is set to Manual.
Run Windows Service as
When Standard System Account is selected (default), the service logs on as Network Service.
The Custom User option must have privileges to log on to Microsoft Windows as a service. The button will be disabled until this user is configured with the required privileges.
A custom user is configured in Windows by searching for "local security policy" in the Start menu. In the Local Security Policy window, select Local Policies, User Rights Assignment, and then Log On As A Service to open the property dialog. Click to add the custom user and then click in each dialog to save the changes.
Deselect the Windows Service option
The Plugins and Extensions step is visible during a new installation of MySQL server version 5.7.12 (or higher) only. If you are upgrading from a previous MySQL version, then you need to open MySQL Installer again and select the Reconfigure MySQL server option.
Enable X Protocol / MySQL as a Document Store (Selected by default.)
When the X Protocol option is selected, MySQL Installer loads and starts the X Plugin. Without the X Plugin running, X Protocol clients cannot connect to the server.
Requires an unused port. The default port number is 33060.
Open Firewall port for network access
Open by default when the X Protocol is selected.
This step is available if the Show Advanced Configuration check box was selected during the Type and Networking step. To enable this step now, click to return to the Type and Networking step and select the check box.
Advanced configuration options are related to the following MySQL log files:
All configuration settings are applied to the MySQL server when you click Configuration Steps tab to follow the progress of each action; the icon for each toggles from white to green on success. Otherwise, the process stops and displays an error message if an individual action times out. Click the Log tab to view the log.. Use the
