利用sshpass批量实现基于key验证脚本

#!/bin/bash

IPLIST="
192.168.1.11
192.168.1.12
192.168.1.13"

rpm -q sshpass &> /dev/null || yum -y install sshpass
[ -f /root/.ssh/id_rsa ] || ssh-keygen -f /root/.ssh/id_rsa  -P ''

export SSHPASS=123456

for IP in $IPLIST;do
    { sshpass -e ssh-copy-id -o StrictHostKeyChecking=no $IP; } &
done
wait
