问题描述
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>
我想改变这个块
<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 ansible 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
然而,AllowOverride All 总是添加到文件末尾.完成这项工作的正确正则表达式模式是什么.我不使用 ansible 模板,因为我只更改了一行.
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
我通过稍微改进 @mattyoung-redhatmatt 的答案来做到这一点.事实证明,replace
模块可以很好地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
