Disclaimer: It is not recommended to login as root. 免责声明： 不建议以root用户身份登录。
But still if you want to, then: 但是，如果您仍然愿意，则：
- Allow
PermitRootLoginin/etc/ssh/sshd_config在/etc/ssh/sshd_config允许PermitRootLogin - Restart SSH service 重新启动SSH服务
- you need to paste the existing public key which is in the
/home/ec2-user/.ssh/authorized_keysto/root/.ssh/authorized_keys您需要将/home/ec2-user/.ssh/authorized_keys的现有公钥粘贴到/root/.ssh/authorized_keys
Now you should be able to login as root using the .pem key. 现在，您应该可以使用.pem密钥以root用户身份登录。

You don't need your root password if you are running sudo su - , you need the password of the user you are running the sudo command as. 如果您正在运行sudo su - ，则不需要root密码，而您正在运行sudo su -的用户则需要密码。 Provided that the user has sudo privileges as root. 前提是该用户具有root用户的sudo特权。 Then you can just run as root: 然后，您可以以root身份运行：
yum install phpmyadmin
