@ WARNING: UNPROTECTED PRIVATE KEY FILE! @
@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@@
Permissions 0644 for 'yourPrivateKey.pem' are too open.
It is required that your private key files are NOT accessible by others.
This private key will be ignored.
Load key "yourPrivateKey.pem": bad permissions
[email protected]: Permission denied (publickey).
解决方法
问题在于yourPrivateKey.pem的权限为可读可写，如下
$ ll
total 24
-rw-------@ 1 zgpeace staff 1.7K Feb 18 07:24 yourPrivateKey.pem
解决为修改为只读权限即可
$ chmod 400 yourPrivateKey.pem
$ ll
total 24
-r--------@ 1 zgpeace staff 1.7K Feb 18 11:24 yourPrivateKey.pem
在初始化系统的时候，引导也有说明
