【Ansible】将文件部署到受管主机1：文件模块

文件模块与 Linux 文件管理相关的大部分常用模块都在ansible.builtin collection 中随 ansible-core 一起提供

ansible.builtin 中的常用⽂件模块：

ansible.builtin 中的常用⽂件模块 (续) ：

确保受管主机上存在⽂件：

- name: touch a file and set permissionsansible.builtin.file:path: /path/to/fileowner: uaer1group: grooup1mode:0640state: touch

修改文件属性：

- name: SELinux type is set to samba_share_tansible.builtin.file:path: /path/to/samba_filesetype: samba_share_file

在受管主机上复制和编辑⽂件：

默认谁执行，文件属于谁，可指定：

Ansible.builtin.copy模块用于将控制节点上Ansible工作目录中的文件复制到选定的受管主机

- name:copy a file to managed hostsansible.builtin.copy:src: filedest: /path/to/file

Ansible.builtin.fetch模块用于从受管主机提取文件

- name: Retrieve SSH key from referrence hostsansible.builtin.fetch:src: “/home/{{ uaer }}/.ssh/id_rsa.pub”dest: “files/keys/{{ user }}.pub”

Ansible.builtin.lineinfile模块用于确保现有文件中存在特定的单行脚本

- name: add a line of text to fileansible.builtin.lineinfile:path: /path/to/fileline: ‘add this line to file’state: present

Ansibile.builtin.blockinfile模块用于将文本块添加到现有文件

- name: add additional lines to fileansible.builtin.blockinfile:    path: /path/to/fileblock：|first linesecond linestate: present

从受管主机中删除⽂件：

使用ansible.builtn.file模块配合state: absent参数

- name: make a file does not xeist on managed hostansible.builtin.file:dest: /path/to/filestate: absent

检索受管主机上的⽂件状态

使用ansible.builtin.stat模块

- name: verify the chedksum of a fileansible.builtin.stat:path: /path/to/filechecksum_algorithm: md5register: result- ansible.builtin.debugmsg: “the checksum of the file is {{ result.stat.checksum }}”

同步控制节点和受管主机之间的⽂件：

使用ansible.posix.synchronnize模块，类似于rsync命令

- name: synchronize local file to remote filesansible.posix.synchoronize:src:filedest: /path/to/file
