C#实现当前ssh远程linux运行某个java命令,如果该命令15分钟内仍未结束则杀死该进程并执行下一条java命令

在C#中,你可以使用SSH.NET库来连接Linux服务器并执行Java命令。以下是一个基本的步骤说明:
1. 首先,你需要安装SSH.NET库,可以通过NuGet包管理器添加`SSHNet`。
```csharp
Install-Package SSHNet
```
2. 创建SSH客户端实例,并连接到远程Linux服务器:
```csharp
using SSH.Net;
string host = "your_server_ip";
int port = 22; // 默认SSH端口,如果是非标准端口,则需更改
string username = "your_username";
string password = "your_password";
using (var client = new SshClient(host, port))
{
client.ConnectionTimeout = TimeSpan.FromSeconds(30); // 设置连接超时时间
client.AuthenticationMethod = AuthenticationMethod.Password;
client.Username = username;
client.Password = password;
try
{
client.Connect();
}
catch (Exception ex)
{
Console.WriteLine($"Failed to connect: {ex.Message}");
return;
}
// 连接成功后,可以执行命令
}
```
3. 使用BackgroundWorker或者Task来执行Java命令,并设置计时器检查命令状态:
```csharp
using System.Threading.Tasks;
string javaCommand = "java -jar your_java_jar.jar"; // 你的Java命令
var commandExecution = Task.Run(() =>
{
var startInfo = new ProcessStartInfo("bash", $"-c '{javaCommand}'");
using (var process = new Process())
{
process.StartInfo = startInfo;
process.Start();
while (!process.HasExited && !process.IsTimedOutAfter(TimeSpan.FromMinutes(15)))
{
// 检查进程是否还在运行
if (process.ExitCode != null) break; // 如果已退出,跳出循环
// 每隔一段时间检查一次,例如每秒
Thread.Sleep(1000);
}
if (process.HasExited && process.ExitCode == 0)
Console.WriteLine("Java command completed successfully.");
else
Console.WriteLine("Killing the Java command due to timeout.");
// 杀死命令进程(假设Process.Kill()可用)
process.Kill();
}
});
// 添加异常处理和任务完成后的清理
commandExecution.ContinueWith(task => HandleCompletion(task));
```
4. 完成部分 (`HandleCompletion`):
```csharp
private void HandleCompletion(Task task)
{
if (task.IsFaulted)
{
Console.WriteLine($"Error executing command: {task.Exception.Message}");
}
else if (task.IsCanceled)
{
Console.WriteLine("Command was canceled.");
}
else
{
Console.WriteLine("Command execution has ended.");
}
// 关闭SSH连接
client.Disconnect();
}
```
