基本执行方法

执行 playbook：

ansible-playbook xxx.yml

playbook 简易示例

--- - name: test_playbook hosts: jeff_linux remote_user: root gather_facts: false tasks: - name: touch /tmp/test.txt ansible.builtin.shell: touch /tmp/test.txt

说明：

• 第一行 --- 是 YAML 文档起始标记
• hosts 指定对哪些主机/主机组执行（可在 /etc/ansible/hosts 定义）
• remote_user 指定远程登录用户
• tasks 定义任务列表，任务里的 name 是执行时打印的说明

创建用户的playbook

--- - name: create_user hosts: jeff_linux remote_user: root gather_facts: false vars: user: test tasks: - name: create user ansible.builtin.user: name: "{{ user }}"

循环

--- - name: loop example hosts: jeff_linux remote_user: root gather_facts: false tasks: - name: change mode for files ansible.builtin.file: path: "/tmp/{{ item }}" state: touch mode: "0600" loop: - 1.txt - 2.txt - 3.txt

条件判断

先获取 facts（示例）：

ansible jeff_linux -m setup

playbook 示例：

--- - name: when example hosts: jeff_linux remote_user: root gather_facts: true tasks: - name: use when ansible.builtin.shell: touch /tmp/when.txt when: ansible_eno16777736.ipv4.address == "192.168.133.132"

Handlers

handlers 类似 “任务触发后再执行动作”（例如重启服务）：

--- - name: handlers test hosts: jeff_linux remote_user: root gather_facts: false tasks: - name: copy file ansible.builtin.copy: src: /etc/passwd dest: /tmp/aaab.txt notify: test handlers handlers: - name: test handlers ansible.builtin.shell: echo "11111" >> /tmp/aaab.txt

playbook-nginx 安装

调用其它的 yml（示例）：

- import_tasks: xxx.yml - import_tasks: xxx.yml

入口文件（roles 示例）：

--- - name: nginx role example hosts: testhosts remote_user: root gather_facts: true roles: - common - install
