Question

以下结构脚本是我需要使用的开源脚本，遗憾的是我不熟悉这些东西。结构文件以：

开头

from fabric.api import *
import time

env.user = 'aegir'
env.shell = '/bin/bash -c'

# Download and import a platform using Drush Make
def build_platform(site, profile, webserver, dbserver, makefile, build):
  print "===> Building the platform..."
  run("drush make %s /var/aegir/platforms/%s" % (makefile, build))

当Git推送触发新构建时，结构文件由Jenkins服务器运行。执行此文件时，第一个远程操作（最后一行）会导致以下错误。

/usr/lib/python2.6/getpass.py:83: GetPassWarning: Can not control echo on the terminal.
  passwd = fallback_getpass(prompt, stream)

我是否必须为aegir用户指定密码？我尝试在env.password = ''下添加passwd --delete aegir（我在我的远程计算机上删除了env.user = 'aegir'的Aegir用户密码），但这并没有解决任何问题。

Answer 1

Ssh服务禁止没有密码的用户进行远程访问。您只需在aegir用户，机器和fabfile中设置密码。

Answer 2

需要登录。为了避免交互性，您可以从FABRIC机器复制公钥并粘贴到TARGET机器的〜/ .ssh / authorized_keys

确保：不包括或排除任何不是密钥的东西（如引入换行符），密钥必须完全按原样复制。

并执行此操作：

chmod 600 ~/.ssh/authorized_keys
chmod 700 ~/.ssh/*

Answer 3

使用此功能并炸弹！

＆＃13;

output['running']  = False     # Avoid fabric to output what it is doing behind the scenes
output['stdout']   = False     # Do not show stdout
output['stderr']   = False     # Do not show stderr
output['status']   = False     # Prevent fabric from using print in some situations (at least in disconnect_all)
output['warnings'] = False     # Avoid fabric from showing messages about failed commands

def run_it(command, user, host, port, keyfile):
    env.host_string = "%s@%s:%s" % (user, host, port)
    env.key_filename = keyfile
    try:
        res = run(command, pty=False, shell=True)
        print "SUCCESS: return_code=%s" % (return_code)
    except Exception, e:
        print "ERROR  : %s" % (e)
        stdout, return_code =  None, None
    return stdout, return_code

＆＃13;

P.S。不要将键列表传递给env.key_filename

Getpass错误
