个人笔记:个人linuxPC登录aws服务器及复制粘贴文件到服务器

先明确一下取名:

The appropriate user names are as follows:

• For an Amazon Linux AMI, the user name is ec2-user.

• For a RHEL AMI, the user name is ec2-user or root.

• For an Ubuntu AMI, the user name is ubuntu or root.

• For a Centos AMI, the user name is centos.

• For a Fedora AMI, the user name is ec2-user.

• For SUSE, the user name is ec2-user or root.

• Otherwise, if ec2-user and root don't work, check with the AMI provider.

1. 下载key,下载完成后用ssh -i指令链接服务器.

jinliang@jinliang-ThinkPad-T450s:~/Downloads$ ssh -i 15619demo.pem [email protected]

提示key的权限 too open,接着输入:

Run "sudo yum update" to apply all updates.

此时已经安全连接.接下来复制本地文件到服务器. 我们在另一个新开的terminal进入到key所在目录,

jinliang@jinliang-ThinkPad-T450s:~/Downloads$ scp -i 15619demo.pem QS4.cpp [email protected]:/home/ec2-user
QS4.cpp                                                                              100% 5131     5.0KB/s   00:00 

此时提示已经上传成功, 注意要用 scp -i 指令,后面跟key的目录, 之后是要复制的文件的目录(此时二者都在一个目录).
