我试图通过连接到Amazon EC2：

I am trying to connect to Amazon EC2 via:

ssh -i ~/.ssh/YOUR_KEYPAIR_FILE.pem ec2-user@YOUR_IP_ADDRESS

终端需要1或2分钟，然后打印：

The terminal takes 1 or 2 mins and then prints:

ssh: connect to host XXX port 22: Operation timed out

任何想法？

推荐答案

你能尝试更改权限YOUR_KEYPAIR_FILE.pem这样 搭配chmod 600 YOUR_KEYPAIR_FILE.pem

Can you try changing permissions to YOUR_KEYPAIR_FILE.pem like this chmod 600 YOUR_KEYPAIR_FILE.pem

然后拍摄的命令 SSH -i YOUR_KEYPAIR_FILE.pem EC2用户@ YOUR_IP_ADDRESS

Then shoot the command ssh -i YOUR_KEYPAIR_FILE.pem ec2-user@YOUR_IP_ADDRESS
