Getting access denied trying to start appfabric cache cluster from powershell_问答_开发者

I have some code that uses appfabric and was getting server unavailability errors. Following the instructions at http://msdn.microsoft.com/en-us/library/ff921031.aspx I found that my cache cluster was down. I opened up powershell as an administrator and ran Start-CacheCluster. After a few minutes I receive an error message:

Start-CacheCluster : Could not start cluster: ErrorCode<ERRCAdmin025>:SubStatus
<ES0001>:Time-out occurred in starting the cluster.
At line:1 char:19

   eException
    + FullyQualifiedErrorId : ERRCAdmin025,Microsoft.ApplicationServer.Caching
   .Commands.StartCacheClusterCommand

Checking the event logs reveals this:

Has anyone with more AppFabric experience seen this before?

-Thanks

Try Microsoft, Windows, Application Server-System Services and Admin log. Sometimes this log will give you some more info that is not present in the regular eventlog. For more information about cache cluster monitoring see Health Monitoring Tools.

Regarding your issue. The only think I would say is that after starting the cache cluster it loads configuration and because it fails, it will eventually crash the AppFabric Caching Service (you will see that information in the eventlog mentioned above).

Make sure you have AppFabric Caching Service configured to run under an account that has access to the configuration file DistributedCacheService.exe.config as well as to the configuration repository (Velocity configuration DB or configuration XML).

You need to run the "Caching administration Windows PowerShell" as Administrator.

Have you checked that the AppFabricCachingService logon has read access to DistributedCacheService.exe.config?

In my case, I am using an XML provider and have a config share named "CacheConfig". My server is not joined to a domain so I have configured a local "AppFabric" user for the cache host. I am using PowerShell to script the config:

Register-CacheHost -Provider XML -ConnectionString "\\MY-HOST\CacheConfig" -Account "AppFabric" -CachePort 22233 -ClusterPort 22234  -ArbitrationPort 22235 -ReplicationPort 22236 -HostName MY-HOST
Add-CacheHost -Provider XML -ConnectionString "\\MY-HOST\CacheConfig" -Account "AppFabric"
#...
Start-CacheCluster
#...

When I ran the script the Start-CacheCluster statement failed with the same access denied error as in your question. I then checked the AppFabricCachingService logon and found it was set to NETWORK SERVICE. When I checked the file permissions on C:\Windows\System32\AppFabric\DistributedCacheService.exe.config, I found that there was a read permission for the AppFabric user, but no permissions for NETWORK SERVICE. This indicates to me that the Register-CacheHost or Add-CacheHost applet assumes that the cache host account and the service account will be the same.

In my case I added a read permission to the file for NETWORK SERVICE and that fixed the problem.

The following isn't your exact problem, but may help: http://social.msdn.microsoft.com/Forums/en-US/velocity/thread/4fd844f6-3530-4115-8982-d7562e699627/#6bf2825a-cd1d-4659-b6ce-375a0fb0ab38

I also ran into the problem since my AppFabric server suffered something unknown. I spent much time for finding the solution. Finally the only way I tried successfully is to uninstall / re-install the AppFabric. And configure the settings once again. Hope this helps !

I had same issue cause I installed appfabric cache service more than one times. Each times hostId was changed it must be same hostId with ClusterConfig.xml and DistributedCacheService.exe.config file
