申请的亚马逊云服务器EC2,实例为ubuntu系统
一、打开终端,定位到放置密钥的文件夹;
二、确保私有秘钥不是公开可见的:
p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px "Andale Mono"; color: #75b900; background-color: #252525 }
span.s1 { }
chmod 400 密钥文件名.pem
三、两种方式连接云服务器:(假设实例的对公IP为:11.22.33.44)
p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px "Andale Mono"; color: #75b900; background-color: #252525 }
span.s1 { }
ssh -i 密钥文件名.pem [email protected]
p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px "Andale Mono"; color: #75b900; background-color: #252525 }
span.s1 { }
ssh -i 密钥文件名.pem [email protected]
两种方式均报错:
p.p1 { margin: 0.0px 0.0px 0.0px 0.0px; font: 14.0px "Andale Mono"; color: #75b900; background-color: #252525 }
span.s1 { }
Permission denied (publickey).
四、解决方法:
在亚马逊官方文档中有下面一段:
Get the default user name for the AMI that you used to launch your instance
- For an Amazon Linux AMI, the user name is
ec2-user
. - For a Centos AMI, the user name is
centos
. - For a Debian AMI, the user name is
admin
orroot
. - For a Fedora AMI, the user name is
ec2-user
orfedora
. - For a RHEL AMI, the user name is
ec2-user
orroot
. - For a SUSE AMI, the user name is
ec2-user
orroot
. - For an Ubuntu AMI, the user name is
ubuntu
orroot
. - Otherwise, if
ec2-user
androot
don‘t work, check with the AMI provider.
最后一条说明存在使用ec2-user和root不能连接的情况,所以需要多尝试一下,由于我装的是ubuntu系统,直接将连接命令中的ec2-user换成ubuntu,完美连接。
