如何获取sudo的密码 [英] How to get password for sudo

问题描述

我正在尝试对PostgreSQL使用命令sudo -i -u postgres，而Google Compute Engine VM要求我提供我的帐户密码(不是root).

I'm trying to use the command sudo -i -u postgres for PostgreSQL, and the Google Compute Engine VM is asking me for my password for my account (not root).

由于我从未发出过密码，而且我总是通过SSH密钥登录服务器，因此我不确定该密码是什么，如何重设密码或在何处可以找到密码.

As I never issued a password, and I always login to my server via SSH key, I'm not sure what the password is, how I can reset it, or where it can be found.

请告诉我在哪里可以获取密码?

Please tell me where I can get my password?

推荐答案

要成为GCE VM上的另一个非root用户，请首先通过无密码的sudo成为root(因为这是配置sudo的方式)在GCE VM映像上):

To become another non-root user on a GCE VM, first become root via password-less sudo (since that's how sudo is configured on GCE VM images):

sudo su -

，然后切换到您要成为的用户或将命令作为另一种用途使用，例如，在您的情况下，是:

and then switch to the user you want to become or run a command as another use, e.g., in your case, that's:

sudo -i -u postgres
