英文:
go execute ssh command and can't kill the command on the remote server
问题
我使用go exec ssh在远程服务器上执行"tail -f"命令。然后我杀死了这个进程，但是"tail -f"命令仍然在远程服务器上运行。
我应该怎么做才能在远程服务器上杀死"tail -f"进程？
我的代码如下：
package main
import (
"os/exec"
"github.com/astaxie/beego"
"time"
)
func main() {
var cmd = exec.Command("ssh","-t", "-p", "9122","deploy@123.com" ,"tail -f /log.out")
var err error
cmd.Start()
time.Sleep(time.Second*5)
err = cmd.Process.Kill() // 当我杀死这个进程时，远程服务器 deploy@123.com 上仍然运行着 'tail -f /log.out'
beego.Error(err)
}
英文:
I use go exec ssh to execute "tail -f" on the remote server. Then I kill the process, but the "tail -f " still runs on the remote server.
What can I do to kill the "tail -f" process on the remote server?
My code is as follows:
package main
import (
"os/exec"
"github.com/astaxie/beego"
"time"
)
func main() {
var cmd = exec.Command("ssh","-t", "-p", "9122","deploy@123.com" ,"tail -f /log.out")
var err error
cmd.Start()
time.Sleep(time.Second*5)
err = cmd.Process.Kill() // when I kill this process, the remote server deploy@123.com still has 'tail -f /log.out' running
beego.Error(err)
}

只需在参数中再添加一个"-t"。
var cmd = exec.Command("ssh", "-t", "-t", "-p", "9122", "deploy@123.com", "tail -f /log.out")

英文:
Just add one more "-t" in the arguments.
var cmd = exec.Command("ssh","-t", "-t", "-p", "9122","deploy@123.com" ,"tail -f /log.out")

你可以尝试发送 Control-C
w, err := cmd.StdinPipe()
ctlC, err := hex.DecodeString(`\x03`) // 在大多数机器上是 CtlC
w.Write(ctlC)
在终止 ssh 之前
err = cmd.Process.Kill()
这在我的设置中有效。
英文:
You can try to send Control-C
w, err := cmd.StdinPipe()
ctlC, err := hex.DecodeString(`\x03`) //CtlC on most machines
w.Write(ctlC)
before killing ssh
err = cmd.Process.Kill()
this works in my setup
