Section 1: Configuring App in SharePoint 2013

1. Create DNS entry for App
   
   Go to Administrative Tools then click on "DNS":
   
   
   
   See the following screen:
   
   
   
   Right-click then select "Create New Alias(CName)". Refer to the following screen:
   
   
   
   Select "same as parent" as in the following screen:

2. DisableLoopbackCheck in regedit (to avoid authentication prompt)
   
   Open the Registry window:
   
   
   
   Go to "HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Lsa" and right-click and select:
   
   
   
   Rename "DisableLoopbackCheck" and right-click on "modify" and change the value to "1". The final output should look as in the following:
   
   
   
3. Check timer job to check spadmin & sptimer services
   
   PowerShell script:
   net start spadminv4
   net start sptimerv4
   
4. Set App Domain
   
   PowerShell script:
   Set-SPAppDomain "<Domain name>"
   
5. Check Appservices and Subscription services
   
   PowerShell script:
   
   Get-SPServiceInstance | where{$_.GetType().Name -eq "AppManagementServiceInstance" -or $_.GetType().Name -eq "SPSubscriptionSettingsServiceInstance"} | Start-SPServiceInstance
   And ensure service:
   Get-SPServiceInstance | where{$_.GetType().Name -eq "AppManagementServiceInstance" -or $_.GetType().Name -eq "SPSubscriptionSettingsServiceInstance"}
   
6. Configuring SPSubscriptionService
   
   PowerShell script:
   $account = Get-SPManagedAccount "<Farm Account>"
   $appPoolSubSvc = New-SPServiceApplicationPool -Name SettingsServiceAppPool –Account$account
   $appPoolAppSvc = New-SPServiceApplicationPool -Name AppServiceAppPool -Account $account
   $appSubSvc = New-SPSubscriptionSettingsServiceApplication –ApplicationPool $appPoolSubSvc –Name SettingsServiceApp –DatabaseName SettingsServiceDB
   $proxySubSvc = New-SPSubscriptionSettingsServiceApplicationProxy –ServiceApplication $appSubSvc
   
7. Configure AppManagement ServiceInstance
   
   PowerShell script:
   $appAppSvc = New-SPAppManagementServiceApplication -ApplicationPool $appPoolAppSvc -Name AppServiceApp -DatabaseName AppServiceDB
   $proxyAppSvc = New-SPAppManagementServiceApplicationProxy -ServiceApplication $appAppSvc
