MySQL Installer for Windows slow query log (including the configuration of seconds it requires to execute a query), and the binary log. The Advanced Options step enables you to set the unique server ID required when binary logging is enabled in a replication topology. The  Enable MySQL Enterprise Firewall  check box is deselected by default. Select this option to enable a security list that offers protection against certain types of attacks. Additional post-installation configuration is required (see Section 6.4.7, “MySQL Enterprise Firewall” ). There is an issue for MySQL 8.0.19 that prevents the server from starting if MySQL Enterprise Firewall is selected during the server configuration steps. If the server startup operation fails, click  Cancel  to end the configuration process and return to the dashboard. You must uninstall the server. The workaround is to run MySQL Installer without MySQL Enterprise Firewall selected. (That is, do not select the  Enable MySQL Enterprise Firewall  check box.) Then install MySQL Enterprise Firewall afterward using the instructions for manual installation (see Section 6.4.7.2, “Installing or Uninstalling MySQL Enterprise Firewall” ). The  Authentication Method  step is visible only during the installation or upgrade of MySQL 8.0.4 or higher. It introduces a choice between two server-side authentication options. The MySQL user accounts that you create in the next step will use the authentication method that you select in this step. MySQL 8.0 connectors and community drivers that use  libmysqlclient 8.0 now support the mysql_native_password  default authentication plugin. However, if you are unable to update your clients and applications to support this new authentication method, you can configure the MySQL server to use  mysql_native_password  for legacy authentication. For more information about the implications of this change, see caching_sha2_password as the Preferred Authentication Plugin. If you are installing or upgrading to MySQL 8.0.4 or higher, select one of the following authentication methods: MySQL 8.0 supports a new authentication based on improved, stronger SHA256-based password methods. It is recommended that all new MySQL server installations use this method going forward. The  caching_sha2_password  authentication plugin on the server requires new versions of connectors and clients, which add support for the new MySQL 8.0 default authentication. Using the old MySQL 5.x legacy authentication method should be considered only in the following cases: 128 •An updated, language-specific connector or driver is not available yet. •Recompilation of an existing application is not feasible. •Applications cannot be updated to use MySQL 8.0 connectors and drivers. •Use Legacy Authentication Method (Retain MySQL 5.x Compatibility) •Use Strong Password Encryption for Authentication (RECOMMENDED) •MySQL Enterprise Firewall (Enterprise Edition only) Important Authentication Method Important
