• Installation Media: Have your SQL Server 2019 Standard installation media ready. This could be a DVD, an ISO file, or a download from Microsoft's website. Make sure you have a legitimate copy to avoid any licensing issues.
• Administrator Privileges: You'll need administrator privileges on the machine where you're installing SQL Server. This is crucial for the installation to proceed without permission errors.
• .NET Framework: SQL Server 2019 requires .NET Framework 3.5 SP1 and .NET Framework 4.6 or later. Ensure these are installed on your system. If not, you can download them from the Microsoft website.

Having these prerequisites in place will ensure a smoother, more efficient installation process. Trust me; it's worth the effort to double-check everything before you begin.

Step-by-Step Installation Guide

Alright, let's get down to the nitty-gritty. Follow these steps, and you'll have SQL Server Standard 2019 up and running in no time.

Step 1: Launch the Setup

First things first, locate your SQL Server 2019 installation media and launch the setup.exe file. This will kick off the SQL Server Installation Center.

Step 2: Choose Installation Type

In the SQL Server Installation Center, you'll see several options. Select 'Installation' from the left-hand menu. Then, choose 'New SQL Server stand-alone installation or add features to an existing installation.' This option starts a fresh installation of SQL Server.

Step 3: Product Key

Next up, you'll be prompted to enter your product key. If you have a product key, enter it here. If you're installing a trial version, you can select the appropriate option to proceed without entering a key. Make sure you have your licensing information handy to avoid any issues down the road.

Step 4: License Terms

Read through the license terms carefully. Once you've understood and agreed to the terms, check the 'I accept the license terms' box and click 'Next.' It's essential to understand what you're agreeing to before proceeding.

Step 5: Global Rules

The setup process will now run a series of global rules to ensure your system meets the basic requirements for installation. If any rules fail, address the issues before continuing. Common issues include insufficient permissions or missing .NET Framework components. Fix these, and then rerun the rules check.

Step 6: Microsoft Update

You'll be asked whether you want to use Microsoft Update to check for updates. It's generally a good idea to enable this option, as it helps ensure you have the latest updates and security patches installed during the setup process. Click 'Next' to continue.

Step 7: Install Rules

The setup will run another set of rules specific to the installation process. Again, address any failures before moving on. This step ensures that all necessary components are in place for a successful installation.

Step 8: Feature Selection

Now comes the fun part – selecting the features you want to install. At a minimum, you'll likely want to select 'Database Engine Services.' Depending on your needs, you might also want to include 'SQL Server Replication,' 'Full-Text and Semantic Extractions for Search,' and 'Client Tools Connectivity.' Choose wisely based on what you plan to do with SQL Server. Keep in mind that you can always add or remove features later if your needs change. Selecting the right features is crucial for optimizing performance and resource usage.

Step 9: Instance Configuration

Next, you'll configure the instance. You can choose to install a 'Default instance' or a 'Named instance.' A default instance is installed without a name and is accessed directly. A named instance, on the other hand, is installed with a specific name and is accessed using that name. For most users, a default instance is sufficient. If you already have a default instance installed, you'll need to choose a named instance. Give your instance a meaningful name if you go with the latter option.

Step 10: Server Configuration

In this step, you'll configure the service accounts and collation settings. For service accounts, you can use the default settings, but it's generally recommended to configure separate accounts for each service for security reasons. Specify the account name and password for each service. For collation settings, the default collation is usually fine, but you can customize it based on your specific language and regional requirements. Choosing the right collation is essential for ensuring proper data sorting and comparison.

Step 11: Database Engine Configuration

This is where you configure the authentication mode and specify the administrators for the SQL Server instance. You can choose between 'Windows Authentication mode' and 'Mixed Mode (SQL Server authentication and Windows authentication).' Mixed Mode allows you to use both Windows accounts and SQL Server accounts for authentication. If you choose Mixed Mode, you'll need to set a strong password for the 'sa' (system administrator) account. Add the current user as a SQL Server administrator by clicking 'Add Current User.' You can also add other users or groups as administrators. Setting up the right authentication mode and administrators is crucial for securing your SQL Server instance.

Step 12: Analysis Services Configuration (If Selected)

If you selected Analysis Services during the feature selection step, you'll need to configure it now. Specify the server mode (Multidimensional and Data Mining Mode or Tabular Mode) based on your needs. Add the current user as an administrator by clicking 'Add Current User.' You can also add other users or groups as administrators. Proper configuration of Analysis Services ensures that you can effectively analyze and report on your data.

Step 13: Reporting Services Configuration (If Selected)

If you selected Reporting Services, you'll need to configure it as well. You can choose to install and configure Reporting Services now, or you can choose to configure it later. If you choose to configure it now, the setup process will guide you through the necessary steps. Configuring Reporting Services allows you to create and manage reports based on your SQL Server data.

Step 14: Distributed Replay Controller and Client (If Selected)

If you selected Distributed Replay Controller and Client, you'll need to configure the controller service. Specify the users who are allowed to administer the Distributed Replay Controller. Configuring Distributed Replay allows you to simulate workloads and test the performance of your SQL Server instance.

Step 15: Ready to Install

The setup process will now show you a summary of the installation settings you've chosen. Review everything carefully to ensure it's correct. If you need to make any changes, click the 'Back' button to go back and modify the settings. Once you're satisfied, click 'Install' to begin the installation process.

Step 16: Installation Progress

The installation process will now begin. This may take some time, depending on the features you've selected and the speed of your system. You can monitor the progress of the installation in the setup window. Be patient and allow the installation to complete without interruption.

Step 17: Complete

Once the installation is complete, you'll see a summary of the installation results. Verify that all components were installed successfully. If any components failed to install, review the error logs to troubleshoot the issues. Once you've addressed any issues, you can rerun the setup process to install the failed components.
