当我使用 ansible module expect 时，我得到了这个消息:需要 pexpect python 模块 [英] When I use ansible module expect, I got this msg: The pexpect python module is required

问题描述

我正在尝试使用 ansible 来部署我们的系统.我在 yml 文件中使用了 expect 模块并尝试使用 ansible-playbook 来运行它并出现此错误:

I am trying to use ansible to deploy our system. I used expect module in yml file and try using ansible-playbook to run it and got this error:

致命:[192.168.100.132]:失败！=> {改变":假，失败":true, "msg": "需要 pexpect python 模块"}

fatal: [192.168.100.132]: FAILED! => {"changed": false, "failed": true, "msg": "The pexpect python module is required"}

然后我从 pypi.python.org 下载了 pexpect-4.2.1 包并通过python setup.py install"安装它.但它不起作用，错误从未改变.我应该怎么做来处理这个错误?

Then I downloaded the pexpect-4.2.1 package from pypi.python.org and install it by "python setup.py install". But it doesn't work and error never changed. What should I do to deal with the error ?

来自 yml 文件的一些代码:

Some code from yml file:

- name: auth root
  expect:
    command: mysql_secure_installation
    responses:
      'Enter password for user root:': '{{password.stdout}}'
      'New password:': 'dtise123'
      'Re-enter new password:': 'dtise123'
      'Do you wish to continue with the password provided\?\(Press y\|Y for Yes, any other key for No\) :': 'y'
      'Remove anonymous users\? \(Press y\|Y for Yes, any other key for No\) :': 'y'
      'Disallow root login remotely\? \(Press y\|Y for Yes, any other key for No\) :': 'y'
      'Remove test database and access to it\? \(Press y\|Y for Yes, any other key for No\) :': 'y'
      'Reload privilege tables now\? \(Press y\|Y for Yes, any other key for No\) :': 'y'
    echo: yes

我从 pypi.python.org 下载了 pexpect-4.2.1.tar.gz 并这样做:

I downloaded the pexpect-4.2.1.tar.gz from pypi.python.org and did like this:

mv pexpect-4.2.1.tar.gz /usr/local/src/
cd /usr/local/src
tar zxvf pexpect-4.2.1.tar.gz
cd pexpect-4.2.1
python setup.py install

推荐答案

我在 Ansible 主机上安装了它 [pexpect].我需要在每个节点机器上安装它吗?

I installed it [pexpect] on the Ansible host. Do I need to install it on each node machine?

是的，模块在目标机器上执行，并且必须在其上安装先决条件(如果存在).

Yes, modules are executed on target machines and prerequisites (if they exist) must be installed on them.
