从 Web 服务器持续同步更改 [英] Continuously sync changes from web server

问题描述

我正在寻找一种方法来将我的文件从 Web 服务器 (Ubuntu 14) 同步(任务)到本地服务器(Windows Server).Web 服务器创建本地服务器需要的小文件.Web 服务器位于 DMZ 中，可通过 SSH 访问.只有本地服务器才能访问 Web 服务器上的文件夹.它尝试使用像 WinSCP 这样的程序，但我无法设置get"-Job.

有没有办法在 Windows 服务器上使用 SSH 做到这一点，而无需每隔几秒登录一次?或者有更好的解决方案吗?未来网络服务是可能的，但目前我需要一个快速的解决方案.

解决方案

或者你需要安排一个经常性的工作，连接和下载变化.

或者您需要持续运行进程，以保持连接打开并定期监视更改.

几乎没有更好的解决方案(这仍然快速且易于实施).

使用WinSCP .NET程序集实现的连续过程示例:

//设置会话选项SessionOptions sessionOptions = 新的 SessionOptions {协议 = 协议.Sftp,主机名 = "example.com",用户名 = "用户",密码 = 我的密码"，SshHostKeyFingerprint = "ssh-rsa 2048 xxxxxxxxxxx...=";};使用(会话会话 = 新会话()){//连接session.Open(sessionOptions);而(真){//下载更改session.SynchronizeDirectories(SynchronizationMode.Local, localPath, remotePath, false).Check();//等待 10 秒线程睡眠(10000)；}}

如果连接中断，您将需要添加更好的错误处理和重新连接.

如果您不想将其实现为 (C#) 应用程序，您可以使用 PowerShell 脚本.有关完整解决方案，请参阅保持本地目录最新(从远程 SFTP/FTP 服务器下载更改的文件)..>

I'm searching for a way to get my Files synchronized (task) from a web server (Ubuntu 14) to a local server (Windows Server). The web server creates small files, which the local Server needs. The web server is in a DMZ, accessible through SSH. Only the local server is able to access folders on web server. It tried using Programs like WinSCP, but I'm not able to set a "get"-Job.

Is there a way to do this with SSH on Windows server without login every few seconds? Or is there a better solution? In the Future Web-Services are possible, but at the moment I need a quick solution.

解决方案

Either you need to schedule a regular frequent job, that connects and downloads changes.

Or you need to have continuously running process, that keeps the connection opened and regularly watches for changes.

There's hardly a better solution (that's still quick and easy to implement).

Example of continuous process implemented using WinSCP .NET assembly:

// Setup session options
SessionOptions sessionOptions = new SessionOptions {
    Protocol = Protocol.Sftp,
    HostName = "example.com",
    UserName = "user",
    Password = "mypassword",
    SshHostKeyFingerprint = "ssh-rsa 2048 xxxxxxxxxxx...="
};

using (Session session = new Session())
{
    // Connect
    session.Open(sessionOptions);

    while (true)
    {
        // Download changes
        session.SynchronizeDirectories(
            SynchronizationMode.Local, localPath, remotePath, false).Check();

        // Wait 10 seconds
        Thread.Sleep(10000); 
    }
}

You will need to add a better error handling and reconnect, if connection breaks.

If you do not want to implement this as (C#) application, you can use PowerShell script. For a complete solution, see Keep local directory up to date (download changed files from remote SFTP/FTP server).
