scp 文件到 ec2 失败，我只想设置好 fever，求帮忙

真心电脑小白一个...又不是cs，哪懂那么多...在 stackoverflow 问了,不想再译回中文了= =。谢谢帮忙...


I'm a newbie and all I want is to set up an ec2 instance for fever rss.
Here is my info: os x 10.9.2, aws with ami of ubuntu 12.04 lts. I set up lamp on ec2 following this guide: http://www.robotmedia.net/2011/04/how-to-create-an-amazon-ec2-instance-with-apache-php-and-mysql-lamp/

Now I can ssh to my server public IP using terminal. After connected the server, I typed

scp -i /path/to/keypair.pem /path/to/test.txt ubuntu@theServerPublicIP:~/

and got the error as follows:

Warning: Identity file keypair.pem not accessible: No such file or directory.

I have tried to resolve the problem by:
1. change permission of .pem file to 600 on my os x.

chmod 600 keypair.pem

and ssh again, scp again, and got same error. Then I change its permission to 400 on my os x,

chmod 600 keypair.pem

and redid ssh and scp, and got same error.

2. rewrite file path using ~/path/to/file for both of keypair.pem and test.txt, and then redid ssh and scp, got same error.
Next rewrite file path using /Users/myUserName/path/to/file for both files and redid ssh and scp, got same error.
Next cd to the folder of keypair.pem and test.txt (I put them in the same folder), and tried the above two naming and got same error for each.

3. change path on the server. I have tried "~","~/","/","/var/www/", for all I still got the same error.

4. I also tried forklift because I saw the developer of Fever using it in the demo video. I tried all options for connection: sftp... but couldn't connect to the server.

Please help to get the test.txt uploaded... then I will be able to upload the fever folder.

Thanks!
