问题描述
我希望能够根据本地目录中的文件列表进行校验和.然后能够获取这些文件的校验和并将其与远程系统上相同文件的校验和进行比较.
I want to be able to do a checksum based on a list of files in a local dir. Then be able to get those files checksum and compare it to the checksum of the same files on a remote system.
我知道我可以通过以下方式获得
I know I can get the with the following
# Local File
- stat:
path: "{{ playbook_dir }}/roles/common/files/myfile.dat"
checksum_algorithm: sha1
delegate_to: localhost
run_once: true
register: localsha_result
# Remote file
- stat:
path: "{{ rmt_dest_dir }}/myfile.dat"
checksum_algorithm: sha1
register: sha_result
并且我试图遍历我想要校验和的文件:
and I have tried to loop through the files that I want to checksum with:
# Gather Files
- name: gather names of files
local_action: shell ls {{ playbook_dir }}/roles/common/files/*.dat | awk -F '/' '{ print $NF }'
register: datfiles
# Local File
- stat:
path: "{{ playbook_dir }}/roles/common/files/{{ item }}"
checksum_algorithm: sha1
with_items: "{{ datfiles.stdout_lines }}"
delegate_to: localhost
run_once: true
register: localsha_result
# Remote file
- stat:
path: "{{ rmt_dest_dir }}/{{ item }}"
checksum_algorithm: sha1
with_items: "{{ datfiles.stdout_lines }}"
register: sha_result
- name: check sha1
fail: msg="SHA1 checksum fails"
when: not sha_result.stat.checksum is defined or not sha_result.stat.checksum == "{{ item.stat.checksum }}"
with_items: "{{ datfiles.stdout_lines}}"
推荐答案
您只需执行两个任务即可完成此操作:(1) 注册本地校验和,(2) 检查远程校验和,将它们与相应的本地进行比较:
You can do this with just two tasks: (1) register local checksums, (2) check remote checksums comparing them to corresponding local:
---
- hosts: test-server
tasks:
- stat:
path: "{{ item }}"
checksum_algorithm: sha1
delegate_to: localhost
with_fileglob: /tmp/*.dat
register: local_files
- stat:
path: "/tmp/{{ item.stat.path | basename }}"
checksum_algorithm: sha1
failed_when: remote_files.stat.checksum != item.stat.checksum
# failed_when condition checked after every iteration
# and remote_files here is a result of individual task
# but after loop is finished, remote_files is a cobination
# of all iterations results
with_items: "{{ local_files.results }}"
register: remote_files
loop_control:
label: "{{ item.stat.path | basename }}"
