#####批量部署ssh私钥认证#####

一、首先安装expect，直接yum即可

二、批量部署ssh私钥脚本

batch_sshkey.sh

==============================================================

#!/bin/bash

cd /root

cat /root/.ssh/id_rsa.pub > /root/.ssh/authorized_keys

for i in `cat ip.txt`

do

ip=$(echo "$i"|cut -f1 -d":")

password=$(echo "$i"|cut -f2 -d":")

expect -c "

spawn scp /root/.ssh/authorized_keys /root/remote_operate.sh root@$ip:/tmp/

expect {

"*yes/no*" {send "yesr"; exp_continue}

"*password*" {send "$passwordr"; exp_continue}

"*Password*" {send "$passwordr";}

}

"

expect -c "

spawn ssh root@$ip "/tmp/remote_operate.sh"

expect {

"*yes/no*" {send "yesr"; exp_continue}

"*password*" {send "$passwordr"; exp_continue}

"*Password*" {send "$passwordr";}

}

"

done

============================================================

ip.txt（前面是IP，后面是密码，用冒号：分割）

192.168.8.23:123456

192.168.8.24:456789

============================================================

remote_operate.sh

#!/bin/bash

if [ ! -d /root/.ssh ];then

mkdir /root/.ssh

fi

cp /tmp/authorized_keys /root/.ssh/

==========================================================

运行batch_sshkey.sh即可。

batch_sshkey.sh设置可执行权限，需./执行，执行过程中无需按回车，自动会完成部署。
