采用TCL脚本实现自动登陆服务器并执行脚本

#!/usr/bin/expect

#设置变量
set passwd "xxx;123"
puts {you want to deploy war , please enter the pool name:}

#从键盘获取输入内容
flush stdout
set pool_name [gets stdin]

puts "you want to deploy $pool_name"
set host "127.0.0.1"
set run_script "/depot/deploy.sh"

#switch判断语句
switch $pool_name {
    xxx {
        set host 10.10.10.10
    }  
   
    default {
        puts "pool name is wrong! exit!"
        exit 1
    }
}
puts "you want to deploy war to $host"

#开启新进程登陆服务器
spawn ssh whtest@$host

#expect期望进程输入内容，send  自动输入内容
expect {
"yes/no" { send "yes\r"; exp_continue}
"password:" { send "$passwd\r" }
}

send "/bin/sh $run_script\r"

#人机交互，停留在进程中，等待用户做其它的操作
interact
