Ansible模块"lineinfile"在多个文件中替换多行 [英] Ansible Module "lineinfile" replace multiple lines in several files

问题描述

我们的SSL证书将在几天内用完.因此，我认为Ansible可以将新证书放到服务器上并更改apache2网站.

our SSL certificate runs out in a couple of days. So I thought Ansible can put the new certs on the server und change the apache2 sites.

服务器站点正在此服务器上运行.

Serveral sites are running on this server.

我要替换以下几行:

• SSLCertificateChainFile
• SSLCertificateKeyFile
• SSLCertificateFile

我使用此命令来获取/etc/apache2中所有模式为"SSLCertificate"的站点的列表.存在.

I use this command to get a list of all sites in /etc/apache2 where the pattern "SSLCertificate" exists.

- name: Apache 2.2 list sites files and store it in register
  command: grep -lR --exclude default-ssl "SSLCertificate" /etc/apache2/
  register: apache22_sites

当只需要更改一个文件时，这就是我所使用的:

This is what I use, when only one file has to be changed:

- name: apache2.2.* | configure certs
  lineinfile: dest=/path/to/...  regexp={{ item.regexp }} line={{ item.line}} backrefs=yes
  with_items:
        - { regexp: "SSLCertificateChainFile", line: "    SSLCertificateChainFile = ..." }
        - { regexp: "SSLCertificateKeyFile ", line: "    SSLCertificateKeyFile = ..." }
        - { regexp: "SSLCertificateFile", line: "    SSLCertificateFile = ..."
  notify: reload apache2

我该如何告诉Ansible将此代码与变量"apache22_sites"中列出的多个文件一起使用? 和倍数行?

How can i tell ansible to use this code with multiple files listed in variable "apache22_sites" and multiples lines?

我发现了一个很好的提示

I found a good hint here, bad sadly only for one line.

我感谢任何小费，技巧和提示:)

I appreciate any tipps, tricks, hints :)

推荐答案

在注释中指出了 tedder42 ，通常，当人们使用 lineinfile 时，最好对这些文件进行模板.

As tedder42 pointed out in the comments, and as is generally the case when people are using lineinfile, you'd be much better off templating these files instead.

但是，如果您想解决更常见的问题，即如何遍历多个事物列表，则应使用 with_nested循环.

However, if you want to solve the more general problem of how you loop through multiple lists of things then you should be using the with_nested loop.

因此，您的情况如下:

- name: Apache 2.2 list sites files and store it in register
  command: grep -lR --exclude default-ssl "SSLCertificate" /etc/apache2/
  register: apache22_sites

- name: apache2.2.* | configure certs
  lineinfile: dest={{ item.0 }}  regexp={{ item.1.regexp }} line={{ item.1.line}} backrefs=yes
  with_nested:
        - apache22_sites
        - lines_to_replace
  notify: reload apache2

只要您在如下位置定义lines_to_replace:

As long as you define your lines_to_replace somewhere like this:

lines_to_replace:
    - { regexp: "SSLCertificateChainFile", line: "    SSLCertificateChainFile = ..." }
    - { regexp: "SSLCertificateKeyFile ", line: "    SSLCertificateKeyFile = ..." }
    - { regexp: "SSLCertificateFile", line: "    SSLCertificateFile = ..."
