1 ansible 常用指令总结,并附有相关示例。


  • /usr/bin/ansible 主程序,临时命令执行工具
  • /usr/bin/ansible-doc 查看配置文档,模块功能查看工具,相当于man
  • /usr/bin/ansible-playbook 定制自动化任务,编排剧本工具,相当于脚本
  • /usr/bin/ansible-pull 远程执行命令的工具
  • /usr/bin/ansible-vault 文件加密工具
  • /usr/bin/ansible-console 基于Console界面与用户交互的执行工具
  • /usr/bin/ansible-galaxy 下载/上传优秀代码或Roles模块的官网平台
利用ansible实现管理的主要方式:

  • Ansible Ad-Hoc 即利用ansible命令,主要用于临时命令使用场景
  • Ansible playbook 主要用于长期规划好的,大型项目的场景,需要有前期的规划过程
ansible 使用前准备
ansible 相关工具大多数是通过ssh协议,实现对远程主机的配置管理、应用部署、任务执行等功能
建议:使用此工具前,先配置ansible主控端能基于密钥认证的方式联系各个被管理节点
1.1 ansible-doc

此工具用来显示模块帮助,相当于man
格式
  1. ansible-doc [options] [module...]
  2. -l, --list #列出可用模块
  3. -s, --snippet #显示指定模块的playbook片段
复制代码
范例:
  1. #列出所有模块
  2. ansible-doc -l
  3. #查看指定模块帮助用法
  4. ansible-doc ping
  5. #查看指定模块帮助用法
  6. ansible-doc -s ping
复制代码
范例: 查看指定的插件
  1. [13:38:40 root@ansible-rocky ~]$ ansible-doc -t connection -l
  2. [13:39:08 root@ansible-rocky ~]$ ansible-doc -t lookup -l
复制代码
1.2 ansible

1.2.1 Ansible Ad-Hoc 介绍

Ansible Ad-Hoc 的执行方式的主要工具就是 ansible
特点: 一次性的执行,不会保存执行命令信息,只适合临时性或测试性的任务
1.2.2 ansible 命令用法

格式:
  1. ansible <host-pattern> [-m module_name] [-a args]
复制代码
选项说明:
  1. --version                               #显示版本
  2. -m module                               #指定模块,默认为command
  3. -v                                      #详细过程 -vv -vvv更详细
  4. --list-hosts                            #显示主机列表,可简写 --list
  5. -C, --check                             #检查,并不执行
  6. -T, --timeout=TIMEOUT                   #执行命令的超时时间,默认10s
  7. -k, --ask-pass                          #提示输入ssh连接密码,默认Key验证
  8. -u, --user=REMOTE_USER                  #执行远程执行的用户,默认root
  9. -b, --become                            #代替旧版的sudo实现通过sudo机制实现提升权限
  10. --become-user=USERNAME                  #指定sudo的run as用户,默认为root
  11. -K, --ask-become-pass                   #提示输入sudo时的口令
  12. -f FORKS, --forks FORKS                 #指定并发同时执行ansible任务的主机数
  13. -i INVENTORY, --inventory INVENTORY     #指定主机清单文件
复制代码
范例:
  1. #先打通基于key验证
  2. #以yanlinux用户执行ping存活检测

1.6 ansible-galaxy

Galaxy 是一个免费网站, 类似于github网站, 网站上发布了很多的共享的roles角色。
Ansible 提供了ansible-galaxy命令行工具连接 https://galaxy.ansible.com 网站下载相应的roles, 进行init(初始化、search( 查拘、install(安装、 remove(移除)等操作。
范例
  1. #搜索项目
  2. [16:05:04 root@ansible-rocky ~]$ ansible-galaxy search lamp
  3. Found 100 roles matching your search:
  4. Name                                      Description

2 总结ansible role目录结构及文件用途。

roles目录结构:
  1. ├── playbook1.yml
  2. ├── playbook2.yml
  3. ├── roles/
  4. │   ├── project1/
  5. │   │        ├── tasks/
  6. │   │        ├── files/
  7. │   │        ├── vars/
  8. │   │        ├── templates/
  9. │   │        ├── handlers/
  10. │   │        ├── default/
  11. │   │        └── meta/
  12. │   ├── project2/
  13. │   │        ├── tasks/
  14. │   │        ├── files/
  15. │   │        ├── vars/
  16. │   │        ├── templates/
  17. │   │        ├── handlers/
  18. │   │        ├── default/
  19. │   │        └── meta/
复制代码
Roles各目录作用
roles/project/ :项目名称,有以下子目录

  • files/ :存放由copy或script模块等调用的文件
  • templates/:template模块查找所需要模板文件的目录
  • tasks/:定义task,role的基本元素,至少应该包含一个名为main.yml的文件;其它的文件需要在此文件中通过include进行包含
  • handlers/:至少应该包含一个名为main.yml的文件;此目录下的其它的文件需要在此文件中通过include进行包含
  • vars/:定义变量,至少应该包含一个名为main.yml的文件;此目录下的其它的变量文件需要在此文件中通过include进行包含,也可以通过项目目录中的group_vars/all定义变量,从而实现角色通用代码和项目数据的分离
  • meta/:定义当前角色的特殊设定及其依赖关系,至少应该包含一个名为main.yml的文件,其它文件需在此文件中通过include进行包含
  • default/:设定默认变量时使用此目录中的main.yml文件,比vars的优先级低
