ansible lineinfile正则表达式多行

我正在尝试使用Ansible编辑apache.conf.这是我的conf的一部分:

I'm trying to edit apache.conf using Ansible. Here's part of my conf:

# Sets the default security model of the Apache2 HTTPD server. It does # not allow access to the root filesystem outside of /usr/share and /var/www. # The former is used by web applications packaged in Debian, # the latter may be used for local directories served by the web server. If # your system is serving content from a sub-directory in /srv you must allow # access here, or in any related virtual host. <Directory /> Options FollowSymLinks AllowOverride None Require all denied </Directory> <Directory /usr/share> AllowOverride None Require all granted </Directory> <Directory /var/www/> Options Indexes FollowSymLinks AllowOverride None Require all granted </Directory> #<Directory /srv/> # Options Indexes FollowSymLinks AllowOverride All # Require all granted #</Directory>

我想更改此块

<Directory /var/www/> Options Indexes FollowSymLinks AllowOverride None Require all granted </Directory>

进入

<Directory /var/www/> Options Indexes FollowSymLinks AllowOverride All Require all granted </Directory>

将"AllowOverride"从无"设置为全部".我正在使用这个烦人的任务

set AllowOverride from None to All. I'm using this ansible task

- name: change htaccess support lineinfile: dest: /etc/apache2/apache2.conf regexp: '\s<Directory /var/www/>\n\sOptions Indexes FollowSymLinks\n\sAllowOverride' line: "AllowOverride All" tags: - test

但是，AllowOverride全部始终添加到文件末尾.什么是正确的正则表达式模式来执行此工作.我不使用ansible模板，因为我只更改一行.

However, AllowOverride All always added to the end of file. What's the correct regex pattern to do this jobs. I don't use ansible template cuz I only change one line.

推荐答案

我设法通过稍微改善@ mattyoung-redhatmatt的答案来做到这一点.事实证明，replace模块可以处理多行正则表达式和反向引用:

I managed to do exactly this by slightly improving @mattyoung-redhatmatt's answer. As it turns out, the replace module handles multi line regular expressions and backreferences just fine:

- name: AllowOverride all replace: dest=/etc/apache2/apache2.conf regexp='(<[dD]irectory /var/www/>[^<]*)AllowOverride None' replace='\1AllowOverride All' backup=yes sudo: yes notify: - restart apache
