Fabric要求输入root密码 [英] Fabric asks for root password

问题描述

我正在使用Fabric运行以下命令:

I am using Fabric to run the following:

def staging():
    """ use staging environment on remote host"""
    env.user = 'ubuntu'
    env.environment = 'staging'
    env.hosts = ['host.dev']
    _setup_path()

def bootstrap():
    """ initialize remote host environment (virtualenv, deploy, update) """
    require('root', provided_by=('staging', 'production'))
    run('mkdir -p %(root)s' % env)
    run('mkdir -p %s' % os.path.join(env.home, 'www', 'log'))
    create_virtualenv()
    deploy()
    update_requirements()

但是我明白了:

[e-mail]:~/projects/proj_name$ fab staging bootstrap
[host.dev] run: mkdir -p /home/ubuntu/www/staging
Password for [e-mail]: 

为什么Fabric要求我输入密码?这是默认的ubuntu根用户，在sudoers文件中没有密码.这是怎么回事?

Why is Fabric asking for my password? This is the default ubuntu root user which has no password in the sudoers files. What's going on here?

推荐答案

meta:刚刚意识到这个问题仍然没有答案.我不知道那里到底发生了什么，但这是一个猜测.

这可能是由于连接到禁用了纯文本密码SSH连接的计算机时未使用密钥文件引起的.

This was probably caused by failing to use a keyfile when connecting to a machine where plaintext password SSH connection was disabled.

正确的用法是:

fab -i keyfile.pem <fabric_task>
