如何在Ansible

Question

我试图在匹配后使用lineinfile在配置文件中添加多行，但我发现生成的行是相反的。这是我的剧本：

  - name: Line test
    lineinfile:
      path: /home/vagrant/abcd
      insertafter: '### AFTER THIS LINE'
      line: "{{ item }}"
      state: present
    with_items:
      - '# This is line 1'
      - '# This is line 2'
      - '# This is line 3' 

以下是结果：

### AFTER THIS LINE
# This is line 3
# This is line 2
# This is line 1

我想要的结果应该是：

### AFTER THIS LINE
# This is line 1
# This is line 2
# This is line 3

据我所知，逆转是由于循环，但如何在不颠倒输入顺序的情况下克服这种情况？我知道有一个blockinfile将文本块按原样放置但是添加了“不可理解的块”标记，这是我不想要的。

感谢。

Answer 1

在对此进行了更多的介绍之后，我发现我可以做到这一点：

 - name: Line test2
   blockinfile:
     path: /home/vagrant/abcd
     marker: "------"
     insertafter: '### AFTER THIS LINE PART 2'
     state: present
     block: |
       # This is line 1
       # This is line 2
       # This is line 3

产生这个：

 ### AFTER THIS LINE PART 2
 ------
 # This is line 1
 # This is line 2
 # This is line 3
 ------

我认为我们的要求是可以接受的。

感谢。

我同意techraf的评论（和你的回答），blockinfile更适合这个目的。但是我想看看如何用lineinfile完成它：

- hosts: 127.0.0.1
  gather_facts: no
  tasks:
  - name: Add temp marker
    lineinfile:
      path: /home/vagrant/abcd
      insertafter: '### AFTER THIS LINE'
      line: "###TEMP MARKER###"
      state: present
  - name: Add content
    lineinfile:
      path: /home/vagrant/abcd
      insertbefore: '###TEMP MARKER###'
      line: "{{ item }}"
    with_items:
      - '# This is line 1'
      - '# This is line 2'
      - '# This is line 3'
  - name: Remove temp marker
    lineinfile:
      path: /home/vagrant/abcd
      line: "###TEMP MARKER###"
      state: absent

要回答@ user2700022的问题：在Windows主机上，我设法通过ansible Windows集合的win_lineinfile模块和块字符|来做到这一点：

    - name: add mod_wsgi config to apache config
      win_lineinfile:
        path: C:\Users\Administrator\AppData\Roaming\Apache24\conf\httpd.conf
        line: |
          LoadFile "c:/python37/python37.dll"
          LoadModule wsgi_module "c:/software/env/lib/site-packages/mod_wsgi/server/mod_wsgi.cp37-win_amd64.pyd"
          WSGIPythonHome "c:/software/env/"
        newline: windows
