脚本多机拷贝ssh公钥

#!/usr/bin/env bash
#ssh-copy-id
rpm -q expect &>/dev/null
if [ $? -ne 0 ];then
        yum -y install expect &>/dev/null
fi
if [ ! -f ~/.ssh/id_rsa  ];then
        ssh-keygen -P "" -f  ~/.ssh/id_rsa
fi
while read ip
do
        {
        ping -c1 -W1 $ip &>/dev/null
        if [ $? -eq 0 ];then
                /usr/bin/expect <<-EOF
                spawn ssh-copy-id root@$ip
                expect {
                        "yes/no" { send "yes\r"; exp_continue }
                        "password:" { send "123456\r" }
                }
                expect eof
                EOF
        fi
        }&
done </ip.txt
wait

在/ip.txt文件中输入想要拷贝主机的ip以后运行以上脚本即可即可
