AWS ｜ssh连接

默认账号ec2-user

该服务器在旧电脑上有保存密钥对，需要对此做更新和替换

在aws控制台登陆实例:

1. 开放ssh权限

$ sudo -i
 
$ vi /etc/ssh/sshd_config
 
PasswordAuthentication no，把 no 改成 yes
#PermitRootLogin prohibit-password 改成 PermitRootLogin yes
 
service sshd restart

2. 重启实例
   

3. 生成key配对

创建成功后会保存pem文件进到本地

3. 执行权限限制

cgnid 400 aws.pem

4. 在本地电脑生成新的公钥

Enter file in which the key is (/Users/txmmy/.ssh/id_ed25519): /Users/txmmy/Downloads/aws.pem
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQCj75FwTnxhP5L1YXhtx+xjiNZZWJ5fHu3YMn1djGCJhn4Cv8TOVDa+ZdBKILoVNFMnrJuH+IIFFjg+ggly+Gpa2/u+mRZHKr28Qebh/lcC67l6Mrg15jrWOjQpjQ4t0dVzAFr5mMA+ixKoR+wB1sgW2rrnym73xR5k3LVDXd5onsv2ourUppbb7ympP0ZEMg7g+PY64XPfdR0+wX/d1o0zdqgThQRwKj0TVWkUZpH8hcx5bzlc9uIIvSqelv0IdwTsYufVZ6UX/OfUQpg93s3LqsITYuSFy6QbA/aplfoGKFxau9CktN+geH+3lqulLYFhyPnK0mdYzzYQg6DdJg7B

5. 替换到aws服务器的～/.ssh/authorized_keys

6. 打开termius，导入pem文件
   

7. 复制ssh命令尝试登陆
