在任何站点中，点Add App，然后点Sharepoint Store，如果没有Enable apps，打开app store的时候出出现错误：

Sorry, apps are turned off. If you know who runs the server, tell them to enable apps.

要开启他，首先要有一个App的DNS，如下新建，如果管理工具里面没有DNS,那么到feature中增加。

Control Panel\System and Security\Administrative Tools

右击Forward Lookup Zones

点New Zone, 一直点Next，然后输入一个域名字。

然后右击新建的域，然后点New Alias

 

如下图设置

 

DNS新建好之后，新建APP Management Service和Subscription Setting Service Application

如果手动新建如下图，也可以运行下面的powershell脚本，就会新建好两个service。

然后确保两个Service是运行的，如下

总之运行下面的脚本就可以开启了

$appManagementService = Get-SPServiceInstance | where {
   $_.TypeName -like 'App Management Service'}if($appManagementService.Status -ne 'Online') {Write-Host 'Starting App Management Service'Start-SPServiceInstance $appManagementService | Out-Null}else{Write-Host 'App Management Service was already started'}# wait for App Management Service to start”while ($service.Status -ne 'Online') {# delay 5 seconds then check to see if service has started sleep 5$service = Get-SPServiceInstance | where {
   $_.TypeName -like 'App Management Service'}}$subscriptionSettingsService = Get-SPServiceInstance | where {
   $_.TypeName -like 'Microsoft SharePoint Foundation Subscription Settings Service'}if($subscriptionSettingsService.Status -ne 'Online') {Write-Host 'Starting Subscription Settings Service'Start-SPServiceInstance $subscriptionSettingsService | Out-Null}else{Write-Host 'Subscription Settings Service was already started'}while ($service.Status -ne 'Online') {# delay 5 seconds then check to see if service has started sleep 5$service = Get-SPServiceInstance | where {

 最后到CA点Apps，点Configure App Urls，就可以看到

当你点app store的时候，其实并没有离开你的站点。

最后当添加的时候出现错误

"Sorry, this app is not supported on your server"

需要去CA激活一个Feature

1. Browse to Central admin

2. Click on 'Application Management'

3. Click 'Manage web applications'

4. Select the web application which hosts the site you are trying to install the app to

5. Click 'Manage Features'

6. 'Apps that require accessible internet facing endpoints' should be deactivate. Click 'Activate'
