root@localhost 的密码是什么? [英] What is the password for root@localhost's password?
问题描述
我正在 windows ubuntu 子系统上配置 hadoop 2.7.3.我使用 root 作为 root 帐户密码，但是当我尝试运行/bin/start-yarn.sh 时，我被要求输入 root@localhost
I'm configuring the hadoop 2.7.3 on windows ubuntu subsystem. I used root as the root account password, but when I try to run /bin/start-yarn.sh, I was required to input the password for root@localhost
lizhi@localhost's password:
我为此尝试过 root，但从未奏效.
I have tried root for this, but never worked.
我也试过
ssh-genkey
cat /home/user/.ssh/id_rsa.pub >> /root/.ssh/authorized_keys
但是调用./start-yarn.sh还是需要密码，这个密码是多少，为什么和root账户密码不一样?
But it still required a password when calling ./start-yarn.sh, what is the password for this, why is it different with root account password?
我尝试使用 passwd 将密码更改为 root，但仍然被拒绝:
I've tried to change password to root using passwd, and I still get denied:
C:\Users\lizhi>bash
lizhi@LAPTOP-SURFACEP:/mnt/c/Users/lizhi$ sudo su
[sudo] password for lizhi:
root@LAPTOP-SURFACEP:/mnt/c/Users/lizhi# passwd
Enter new UNIX password:
Retype new UNIX password:
passwd: password updated successfully
root@LAPTOP-SURFACEP:/mnt/c/Users/lizhi# ssh localhost
root@localhost's password:
Permission denied, please try again.
root@localhost's password:
Permission denied, please try again.
root@localhost's password:
Received disconnect from 127.0.0.1: 14:
root@LAPTOP-SURFACEP:/mnt/c/Users/lizhi#
欢迎提出任何建议.
推荐答案
除非你设置它，否则它是空白的(如"):
It is blank (as in "") unless you set it:
ssh root@localhost 对 root 使用相同的密码.看起来您还没有设置root密码.为此，请使用 sudo -s 以 root 身份登录，然后使用 passwd 命令设置 root 密码.
ssh root@localhost uses the same password for root. It looks like you have not set root password.
To do that log in as root using sudo -s then use passwd command to set root password.
之后你必须能够以 root 身份 ssh
After that you must be able to ssh as root
