旁路错误

下面的结构脚本是我需要使用的开源代码，不幸的是我对这个东西并不熟悉。结构文件开头为：旁路错误

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 push触发新构建时，构造文件由Jenkins服务器运行。当执行这个文件时，第一个远程动作（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)

我需要为aegir用户指定一个密码吗？我试图在env.user = 'aegir'下包含env.password = ''（我在远程计算机上删除了Aegir的用户密码passwd --delete aegir），但这并没有解决任何问题。

ssh服务禁止没有密码的用户进行远程访问。您可以在机器上和fabfile中为aegir用户设置密码。

好的，那确实是问题所在。愚蠢的我没有尝试。谢谢！ – jroeleveld

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

请确保：不要包含或排除任何不是关键的东西（如引入换行符），密钥必须完全按原样复制。

，并做到这一点：

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

如果以上所有都失败了，该怎么办？ – Max

使用此功能和炸弹！

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 = "%[email protected]%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

附：不要将密钥列表传递给env.key_filename
