Question

在这里，我试图测试我的bash脚本，它会提示四次。

#!/bin/bash
date >/opt/prompt.txt
read -p "enter one: " one
echo $one
echo $one >>/opt/prompt.txt
read -p "enter two: " two
echo $two
echo $two >>/opt/prompt.txt
read -p "enter three: " three
echo $three
echo $three >>/opt/prompt.txt
read -p "enter password: " password
echo $password
echo $password >>/opt/prompt.txt

对于这个脚本，我在下面写了代码，它工作正常，

- hosts: "{{ hosts }}"
  tasks:
  - name: Test Script
    expect:
      command: sc.sh
      responses:
        enter one: 'one'
        enter two: 'two'
        enter three: 'three'
        enter password: 'pass'
      echo: yes

但如果我对mysql_secure_installation命令做同样的事情，它对我不起作用，

- hosts: "{{ hosts }}"
  tasks:
  - name: mysql_secure_installation Command Test
    expect:
      command: mysql_secure_installation
      responses:
        'Enter current password for root (enter for none):': "\n"
        'Set root password? [Y/n]:': 'y'
        'New password:': '123456'
        'Re-enter new password:': '123456'
        'Remove anonymous users? [Y/n]:': 'y'
        'Disallow root login remotely? [Y/n]:': 'y'
        'Remove test database and access to it? [Y/n]:': 'y'
        'Reload privilege tables now? [Y/n]:': 'y'

      echo: yes

及其引用在这里：

我还尝试空白''而不是"\n"作为第一个答案，但它也无效。我还访问了ansible expect doc，但这里有非常简单的例子和解释。我也尝试正则表达式匹配多个不同的响应，但它也无法正常工作。请不要建议我使用ansible的mysql模块，因为这里我的目的是学习这个模块以备将来使用。

Answer 1

原因是这些问题被解释为正则表达式。因此，您必须在正则表达式中转义具有特殊含义的字符，例如 - （）[] \？*。 et cetara。

因此：

'Enter current password for root (enter for none):'

应改为：

'Enter current password for root \(enter for none\):'

祝你好运！

如何使用ansible＆＃39;期望＆＃39;模块用于多种不同的响应？
