Expect--自动批量分发公钥脚本

1.在使用之前，先安装epel源，yum install expect
2.写分发脚本，后缀为exp

#!/usr/bin/expect
set host_ip [lindex $argv 0]
spawn ssh-copy-id -i /root/.ssh/id_rsa.pub $host_ip
expect {
-timeout 60
"(yes/no)?" { send "yes\n";exp_continue}
"password:" { send "123456\n"}
timeout {puts "Connect timeout!";return}
}
expect eof
exit -onexit {
send_user "Job has finished!"
}

注：set的作用是设置变量，spawn设置执行命令时，可以引用变量；变量的第一个参数为0

3.设置变量列表，并调用自动分发脚本；后缀为sh

#!/bin/bash
iplist=(
192.168.0.241
192.168.0.242
192.168.0.243
)
for ip in ${iplist[*]};do
expect /root/ssh164.exp $ip
done

4.开始分发
#sh ssh164.sh
