通过 jenkins 将 shell 脚本运行到 ssh 远程服务器，登录服务器后连接断开

Question

我的 shell 脚本是：

#!/usr/bin/expect -f
set image [lindex $argv 0]
set version [lindex $argv 1]
send_user "$image $version"
set timeout 10
#spawn su
spawn ssh root@192.168.192.60
#spawn su jenkins -c "root@192.168.192.60"
expect "*password:"
send "supercxp\r"
expect "*#"
exec sleep 5
send "cd /home/admin/OS\r"
send "ll -ltr\r"
send "./Gettar.sh $image $version\r"
send "./upgrade_to_new_version.sh $image $version\r"
send "exit\r"
interact

This script runs successfully on Terminal,while I run it by jenkins,the ssh connection stopped without any error.The output on jenkins is: enter image description here

登录服务器时没有执行“send xxx”命令。有人遇到过这个问题吗？
