Setting up SharePoint 2019 on-premises involves several steps, including installing and configuring the necessary software, creating and configuring the farm and web applications, and deploying and configuring the SharePoint components. Here's a general overview of the process:
- Install the necessary software, including Windows Server, SQL Server, and the SharePoint 2019 software.
- Create and configure the farm by running the SharePoint Configuration Wizard. This involves specifying the database server and creating the configuration database.
- Create and configure web applications by using the Central Administration site. This includes creating the web application, creating the site collection, and configuring the web application settings.
- Install and configure the SharePoint components, such as Service Applications, Search, and User Profile Service.
- Configure the security settings, including user authentication and authorization.
- Configure service accounts, managed accounts, and secure store service.
- Configure and deploy the search service.
- Configure and deploy the user profile service.
- Create and configure the site collections and web applications.
- Test the installation and configurations
It is important to note that this is a high-level overview of the process and depending on the complexity of your SharePoint environment, the process may be more involved and require additional steps. Additionally, it is important to have a solid plan in place before starting the setup and also have a backup plan in case of any issues.
It is also important to note that SharePoint 2019 is the last version of on-premises SharePoint, after that Microsoft is only going to support SharePoint Online and SharePoint Server 2022. It's recommended to evaluate the costs and benefits of migrating to SharePoint Online.
