linux - 无法无密码登录 ssh localhost，start-all.sh 权限被拒绝

Question

我已经被这个问题困扰了几天了。我试图在本地将 hadoop 设置为伪分布式。我已经成功安装了 java 并设置了变量。但我被困在 ssh localhost 上。我无法通过密码请求屏幕，并且 start-dfs.sh 一直拒绝我的权限。我假设它们是相关的？

fad@fad-System-Product-Name:~$ start-dfs.sh
Starting namenodes on [localhost]
localhost: fad@localhost: Permission denied (publickey,password).
Starting datanodes
localhost: fad@localhost: Permission denied (publickey,password).
Starting secondary namenodes [fad-System-Product-Name]
fad-System-Product-Name: fad@fad-system-product-name: Permission denied (publickey,password).

感谢您的帮助，谢谢!

将您的用户名授予 super 用户访问权限，然后按照此操作

sudo apt-get install openssh-server
sudo su yourusername
ssh-keygen -t rsa -P ""

当询问详细信息时，只需按 Enter

cat $HOME/.ssh/id_rsa.pub >> $HOME/.ssh/authorized_keys
