将Azure文件服务CloudFileShare映射为每个云服务实例上的虚拟目录 [英] Mapping an Azure File Service CloudFileShare as a virtual directory on each instance of a cloud service

问题描述

我有一个天蓝色的云服务，我正在尝试升级该服务以获得高可用性，并且我已订阅了已在预览门户中启用的Microsoft Azure文件服务预览.我创建了一个新的存储帐户，可以看到该存储帐户现在具有位于以下位置的文件"端点:

I have an azure cloud service which I am attempting to upgrade for high availability and I have subscribed to the Microsoft Azure File Service preview which has been enabled in the preview portal. I have created a new storage account and can see the storage account now has a Files endpoint located at:

https://<account-name>.file.core.windows.net/

在我的网络角色中，我有以下代码，看起来是否在创建名为scorm的共享，如果没有创建，则创建它:

Within my web role I have the following code which looks to see if a share called scorm is created and if not it creates it:

public static void CreateCloudShare()
{
    CloudStorageAccount account = CloudStorageAccount.Parse(System.Configuration.ConfigurationManager.AppSettings["SecondaryStorageConnectionString"].ToString());
    CloudFileClient client = account.CreateCloudFileClient();
    CloudFileShare share = client.GetShareReference("scorm");
    share.CreateIfNotExistsAsync().Wait();
}

这没有问题.我的问题是我不确定如何在Cloud Service中映射作为虚拟目录创建的CloudShare.在一个实例上，我能够做到这一点:

This works without issue. My problem is that I am unsure as to how to map the CloudShare that has been created as a virtual directory within my cloud service. On a single instance I was able to do this:

public static void CreateVirtualDirectory(string VDirName, string physicalPath)
{
    try
    {

        if (VDirName[0] != '/')
            VDirName = "/" + VDirName;

        using (var serverManager = new ServerManager())
        {
            string siteName = RoleEnvironment.CurrentRoleInstance.Id + "_" + "Web";
            //Site theSite = serverManager.Sites[siteName];
            Site theSite = serverManager.Sites[0];
            foreach (var app in theSite.Applications)
            {
                if (app.Path == VDirName)
                {
                    // already exists
                    return;
                }
            }
            Microsoft.Web.Administration.VirtualDirectory vDir = theSite.Applications[0].VirtualDirectories.Add(VDirName, physicalPath);
            serverManager.CommitChanges();
        }
    }
    catch (Exception ex)
    {
        System.Diagnostics.EventLog.WriteEntry("Application", ex.Message, System.Diagnostics.EventLogEntryType.Error);
        //System.Diagnostics.EventLog.WriteEntry("Application", ex.InnerException.Message, System.Diagnostics.EventLogEntryType.Error);
    }
}

我已经查看并看到可以通过powershell进行映射，但是我不确定如何在Web角色中调用代码.我添加了以下方法来运行powershell代码:

I have looked and seen that it is possible to map this via powershell but I am unsure as to how I could call the code within my web role. I have added the following method to run the powershell code:

public static int ExecuteCommand(string exe, string arguments, out string error, int timeout)
{
    Process p = new Process();
    int exitCode;
    p.StartInfo.FileName = exe;
    p.StartInfo.Arguments = arguments;
    p.StartInfo.CreateNoWindow = true;
    p.StartInfo.UseShellExecute = false;
    p.StartInfo.RedirectStandardError = true;
    p.Start();
    error = p.StandardError.ReadToEnd();
    p.WaitForExit(timeout);
    exitCode = p.ExitCode;
    p.Close();

    return exitCode;
}

我知道我必须运行的命令是:

I know that the command I have to run is:

net use z: \\<account-name>.file.core.windows.net\scorm /u:<account-name> <account-key>

如何在我的网络角色中使用它?我的网络角色代码如下，但似乎不起作用:

How can I use this from within my web role? My web role code is as follows but does not seem to be working :

public override bool OnStart()
{
    try
    {

        CreateCloudShare();
        ExecuteCommand("net.exe", "user " + userName + " " + password + " /add", out error, 10000);
        ExecuteCommand("netsh.exe", "firewall set service type=fileandprint mode=enable scope=all", out error, 10000);
        ExecuteCommand("net.exe", " share " + shareName + "=" + path + " /Grant:" + userName + ",full", out error, 10000);

    }
    catch (Exception ex)
    {
        System.Diagnostics.EventLog.WriteEntry("Application", "CREATE CLOUD SHARE ERROR : " + ex.Message, System.Diagnostics.EventLogEntryType.Error);
    }
    return base.OnStart();
}
