批量部署ssh私钥认证

vim  batch_sshkey.sh

#!/bin/bash
cd /root
cat /root/.ssh/id_rsa.pub > /root/.ssh/authorized_keys
for i in `cat iplist`
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 [email protected]$ip:/tmp/
expect {
\"*yes/no*\" {send \"yes\r\"; exp_continue}
\"*password*\" {send \"$password\r\"; exp_continue}
\"*Password*\" {send \"$password\r\";}
}
"

expect -c "
spawn ssh [email protected]$ip "/tmp/remote_operate.sh"
expect {
\"*yes/no*\" {send \"yes\r\"; exp_continue}
\"*password*\" {send \"$password\r\"; exp_continue}
\"*Password*\" {send \"$password\r\";}
}
"
done

vim  iplist（前面是IP，后面是密码，用冒号：分割）

192.168.8.23:123456
192.168.8.24:456789

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

vim remote_operate.sh

#!/bin/bash
if [ ! -d /root/.ssh ];then
mkdir /root/.ssh
fi
cp /tmp/authorized_keys /root/.ssh/
rm -f /tmp/authorized_keys
rm -f $0

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

运行batch_sshkey.sh后即可实现批量部署。
