需求

批量实现自动发送公钥到远程主机

环境

firewalld：关闭
selinux：关闭

实现方式

• sshpass命令
• shell调用expect命令
  

sshpass命令

shell调用expect命令

#!/bin/bash##********************************************************************#Author: hechunping#QQ: ×××#Date: 2019-11-07#FileName: ssh-expect.sh#URL: hexiaoshuai.blog.51cto.com#Description: The test script#Copyright (C): 2019 All rights reserved#********************************************************************NET=172.20.200USER=(root hechunping)PASSWORD=123456ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa &> /dev/nullfor i in {1..254} ; do{expect <<EOFspawn ssh-copy-id -i ${USER[0]}@${NET}.${i}expect { "yes/no" { send "yes\n";exp_continue } "password" { send "${PASSWORD}\n" }}expect eofEOF}&donewait
