EC2免pem用密碼登陸

原理

EC2在初始化實例時，會運行cloud-init腳本一次。

我們可以在cloud-init腳本中修改登陸的安全設置PasswordAuthentication

默認PasswordAuthentication是no

操作

在設置實例信息時，打開“高級詳細信息”

填入如下信息

#cloud-config
password: 《你要設置的登陸密碼》
chpasswd: { expire: False }
ssh_pwauth: True

如圖

登陸

在系統初始化完之後，可以直接使用

ssh ec2-user@你的實例的ip地址

就能登陸了。

中間會提示輸入登陸密碼
