shell脚本实现ssh-copy-id批量自动发送公钥到远程主机
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
#!/bin/bash # #******************************************************************** #Author: hechunping #QQ: ××× #Date: 2019-11-07 #FileName: ssh-sshpass.sh #URL: hexiaoshuai.blog.51cto.com #Description: The test script #Copyright (C): 2019 All rights reserved #******************************************************************** NET=172.20.200 USER=(root hechunping) PASSWORD=123456 ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa &> /dev/null sed -i '/StrictHostKeyChecking/c StrictHostKeyChecking no' /etc/ssh/ssh_config rpm -q sshpass &> /dev/null || yum -y install sshpass &> /dev/null for i in {1..254} ; do { sshpass -p $PASSWORD ssh-copy-id -i ${USER[0]}@${NET}.${i} &> /dev/null }& done wait
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=172.20.200 USER=(root hechunping) PASSWORD=123456 ssh-keygen -t rsa -P '' -f ~/.ssh/id_rsa &> /dev/null for i in {1..254} ; do { expect <<EOF spawn ssh-copy-id -i ${USER[0]}@${NET}.${i} expect { "yes/no" { send "yes\n";exp_continue } "password" { send "${PASSWORD}\n" } } expect eof EOF }& done wait
