批量命令：CentOS使用expect批量远程执行脚本和命令

#!/usr/bin/expect -f
set password rootpassword
for {set i 102} {$i <= 112} {incr i} {
  set ip "192.168.0.$i"
  puts "$ip"

  spawn ssh -o StrictHostKeyChecking=no $ip
  set timeout 3
  expect "root@$ip's password:"
  set timeout 3
  send "$password\r"
  set timeout 3
  send "exit\r"

  spawn scp /home/install/rc.local root@$ip:/etc/rc.d/rc.local
  set timeout 3
  expect "root@$ip's password:"
  set timeout 3
  send "$password\r"
  set timeout 3
  send "exit\r"  spawn ssh root@$ip
  expect {
  "*yes/no" { send "yes\r"; exp_continue}
  "*password:" { send "$password\r" }
  }
  expect "#*"
  #要执行的命令
  send "chmod +x /etc/rc.d/rc.local\r"
  send "reboot\r"
  send "exit\r"
  expect eof
}
