1. 本地连接aws的ec2实例，出现如下报错

$ ssh -i dev-use.pem ec2-user@10.0.134.235                 
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
@         WARNING: UNPROTECTED PRIVATE KEY FILE!          @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
Permissions 0777 for '/Users/jack/.ssh/dev-eks-use.pem' are too open.
It is required that your private key files are NOT accessible by others.

Load key "/Users/jack/.ssh/dev-eks-use.pem": bad permissions
ec2-user@10.0.134.235: Permission denied (publickey,gssapi-keyex,gssapi-with-mic).

2. 解决方法

$ chmod 400 dev-use.pem

3. 再次连接成功

$ ssh -i dev-use.pem ec2-user@10.0.134.235   

A newer release of "Amazon Linux" is available.
