Can't create a site collection through SharePoint Managment Shell for SharePoint 2010 - sharepoint-2010

Question

I tried to run the same commands as in here -https://technet.microsoft.com/en-us/library/cc263165(v=office.14).aspx .
$template = Get-SPWebTemplate "STS#0"
New-SPSite -Url "http://web-application-name/sitecollection1" -OwnerAlias "domain\administrator" -Template $template
I am getting the following error:
New-SPSite : A site collection could not be created as the provided managed pat
h does not exist. Change the URL to use an existing managed path or create the
missing managed path prior to calling this command.
What does this error mean? What am i missing?

Answer 1

1.$template = Get-SPWebTemplate "STS#0"
if you are getting error upon running this command use this link https://support.microsoft.com/en-us/help/2796733/sharepoint-2010-management-shell-does-not-load-with-windows-powershell-3.0
to fix it
2.Create a managed path
New-SPManagedPath -RelativeURL "sitecollection1" -WebApplic ation "web-application-name"
3.Create the site collection
New-SPSite -URL "http://web-application-name/sites/sitecollection1"-OwnerAlias "domain\administrator" -Template $template
It is not very clear for my how to create a site collection with a path like:
http://web-application-name/sitecollection2
But this solution worked for what i needed.
