Question

我正在尝试使用expect脚本登录虚拟机（VM）后安装rpm包。日志记录很好但是在尝试运行rpm命令时它正从VM退出并返回到被叫机器。该命令调用rpm安装 rpm -ivh --force pkg_name

使用expect登录即可使用产生ssh root@1.1.1.1然后当它需要我发送的密码时。

有人遇到过这样的问题吗？任何帮助都会有用。谢谢。

以下是登录系统的expect文件 login_script.exp

#!/usr/bin/expect

set timeout 60
set prompt {[#>$] }

system "rm -f ~/.ssh/known_hosts" 
spawn ssh root@1.1.1.1

expect {
    "yes/no" {
         send "yes\r"
         expect {
              "*?assword: " {
                   send "abcdefgh\r" 
                   expect -re $prompt {}
                   }
                }
             }
    "*?assword" { 
         send "abcdefgh\r"
         expect -re $prompt {}
             }
    }
send "sleep 1\r"
send "sudo -i\r"
expect "*?assword" { send "abcdefgh\r" }

原始脚本将调用

/usr/bin/expect << -EOF-
source login_script.exp

expect "\$prompt"    ;# wait for prompt
send "rpm -ivh --force /tmp/pkg_abc\r"
expect "\$prompt"    ;# wait for prompt
-EOF-

两者的输出：
