Question

我使用此Playbook命令从远程计算机获取数据库：

ansible-playbook -K -vvv ansible/fetch-database.yml

剧本的第一部分如下：

---

- name: Set this playbook to run on the live server
  hosts: webservers
  remote_user: jon
  become_method: su
  become_user: root

  roles:
    - fetch-database

角色的第一个任务就是从这个开始的（还有其他任务，但Ansible崩溃才能到达它们，所以我认为它们不相关）：

---

- name: Install the MySQL packages to support MySQL exporting on the remote in Python
  apt: name={{ item }} state=installed update_cache=yes
  become: true
  with_items:
   - python-mysqldb

这样做的目的是在Ubuntu远程服务器上安装数据库库，这样我就可以进行MySQL转储，然后将SQL文件提取回我的本地主机。

我使用Paramiko作为SSH驱动程序，因此在我的本地配置ansible.cfg中配置：

[defaults]
transport=paramiko

不幸的是我收到了这个错误：

An exception occurred during task execution. The full traceback is:

fatal: [server.example.com]: FAILED! => {"failed": true, "msg": "Unexpected failure during module execution.", "stdout": ""}

看起来我的root密码是以ASCII身份传递的，而且它似乎在英镑符号（£）上挣扎。我认为这是主要的错误：

UnicodeEncodeError：'ascii'编解码器无法对位置1中的字符u'\ xa3'进行编码：序数不在范围内（128）

我猜这是一个错误（因为它处理得不好），但我无法想象之前没有人发现过这个错误。因此，我认为有一些选项可以通过UTF-8传递此密码 - 如果是这样，我该怎么做？

我正在使用来自GitHub的Ansible的当前devel分支，哈希46a97e1f551。我猜这个问题会受到使用中的子模块的影响，所以为了完整性，它们如下：

 1d0d5db97a26fefc5ce462ef5fac84086122bbe3 lib/ansible/modules/core (heads/devel-165-g1d0d5db)
 00b8b96906a741afa8eaa1245d0e229f099318a5 lib/ansible/modules/extras (heads/devel-116-g00b8b96)

我认为这不重要，因为它感觉像是Python问题或配置问题，但本地和远程机器都是Ubuntu 14.04。

我目前的解决方案是禁用Paramiko并使用默认的SSH传输机制。这之前没有用，并挂在需要su的命令上，这就是为什么我首先交换到Paramiko的原因。然而，这个问题似乎最近已得到修复。

Paramiko问题的错误报告is here。

我是否需要明确切换Paramiko或Ansible以使用UTF-8处理su密码中的非ASCII字符？
