临时有个需求：几十台机器的安全日志拷贝到一台指定服务器上。
考虑1. 最好是BS实现，如果是CS结构，每台机器都要部署agent
考虑2：每台服务器的安全日志文件命名是一样的，如果直接放到同一个目录下，重名导致覆盖
由此想到ansible的fetch模块，ansible是BS架构，fetch模块支持原始目录拷贝。但是直接用fetch模块不可行，因为支持单个文件。比如下面的写法会报错
ansible all -m fetch -a "src=/var/log/secure* dest=/tmp/,mode=0777"
ansible-playbook可以实现（但是目前没有找到取文件的同时改权限，可能因为mode不在fetch模块下面）。
下面是官方举例介绍（https://docs.ansible.com/ansible/latest/modules/fetch_module.html#examples ）：
- name: Store file into /tmp/fetched/host.example.com/tmp/somefile
fetch:
src: /tmp/somefile
dest: /tmp/fetched
- name: Specifying a path directly
fetch:
src: /tmp/somefile
dest: /tmp/prefix-{{ inventory_hostname }}
flat: yes
- name: Specifying a destination path
fetch:
src: /tmp/uniquefile
dest: /tmp/special/
flat: yes
- name: Storing in a path relative to the playbook
fetch:
src: /tmp/uniquefile
dest: special/prefix-{{ inventory_hostname }}
flat: yes如果flat为yes，不按照src的目录来创建目录。flat为no就创建和src一样的目录。下面是实际使用案例：
[root@node1 ~]# cat secure_fetch.yml
---
- name: 取secure日志
become: yes
become_method: su
hosts: test
gather_facts: no
tasks:
- name: find log
find:
paths: /var/log/
patterns: "secure*"
#recurse参数 : 默认情况下，只会在指定的目录中查找文件，也就是说，如果目录中还包含目录，ansible 并不会递归的进入子目录查找对应文件，如果想要递归的查找文件，需要使用 recurse 参数，当 recurse 参数设置为 yes 时，表示在指定目录中递归的查找文件。
recurse: no
#register是钩子
register: file_fetch
- name: fetch log
fetch:
src: "{{ item.path }}"
dest: /home/securelog/
flat: no
with_items: "{{ file_fetch.files }}"[root@node1 ~]# ansible-playbook secure_fetch.yml
