前言
當下有許多的運維自動化工具( 配置管理 )，例如：Ansible、SaltStack、Puppet、Fabric 等。
Ansible 一種集成 IT 系統(tǒng)的配置管理、應用部署、執(zhí)行特定任務的開源平臺，是 AnsibleWorks 公司名下的項目，該公司由 Cobbler 及 Func 的作者于 2012 年創(chuàng)建成立。
Ansible 基于 Python 語言實現，由 Paramiko 和 PyYAML 兩個關鍵模塊構建。
Ansible 特點：
- 部署簡單，只需在主控端部署 Ansible 環(huán)境，被控端無需做任何操作。
- 默認使用 SSH（Secure Shell）協(xié)議對設備進行管理。
- 主從集中化管理。
- 配置簡單、功能強大、擴展性強。
- 支持 API 及自定義模塊，可通過 Python 輕松擴展。
- 通過 Playbooks 來定制強大的配置、狀態(tài)管理。
- 對云計算平臺、大數據都有很好的支持。
- 提供一個功能強大、操作性強的 Web 管理界面和 REST API 接口 ---- AWX 平臺。
給定 SaltStack 的 Ansible：
- 最大的區(qū)別是 Ansible 無需在被監(jiān)控主機部署任何客戶端代理，默認通過 SSH 通道進行遠程命令執(zhí)行或下發(fā)配置。
- 相同點是都具備功能強大、靈活的系統(tǒng)管理、狀態(tài)配置，都使用 YAML 格式來描述配置，兩者都提供豐富的模板及 API，對云計算平臺、大數據都有很好的支持。

4 ansible常用模塊
shell > ansible-doc -l # 列出 Ansible 支持的模塊
shell > ansible-doc ping # 查看該模塊幫助信息
復制代碼
4.1 遠程命令模塊（command / script / shell）
4.1.1 命令
command 作為 Ansible 的默認模塊，可以運行遠程權限范圍所有的 shell 命令，不支持管道符。
shell > ansible Client -m command -a "free -m" # 查看 Client 分組主機內存使用情況
復制代碼
4.1.2 腳本
script 的功能是在遠程主機執(zhí)行主控端存儲的 shell 腳本文件，相當于 scp + shell 組合。
shell > ansible Client -m script -a "/home/test.sh 12 34" # 遠程執(zhí)行本地腳本

4.1.3 外殼
shell模塊基本和command相同，但是shell支持管道符
shell > ansible Client -m shell -a "/home/test.sh" # 執(zhí)行遠程腳本

4.2 copy模塊
實現主控端向目標主機拷貝文件，類似于 scp 功能
shell > ansible Client -m copy -a "src=/home/test.sh dest=/tmp/ owner=root group=root mode=0755" # 向 Client 組中主機拷貝 test.sh 到 /tmp 下，屬主、組為 root ，權限為 0755

5 ansible-playbook 詳解
5.1 YAML語法
- YAML的語法和其他高階語言類似并且可以簡單表達清單、散列表、標量等數據結構。（列表用橫桿表示，鍵值對用冒號分割，鍵值對里又可以嵌套另外的鍵值對）
- YAML文件擴展名通常為.yaml或者.yml。下面為示例
- 一定要對齊，只能使用空格
name: tom
age: 21
gender: male
spourse:
name: lily
gender: female
children:
- name: susan
age: 2
gender: feamle
- name: sunny
age: 10
gender: male
復制代碼
5.2 核心組件
- tasks：任務
- variables：變量
- templates：模板
- handlers：處理器
- roles：角色
5.3 playbook簡單示例
5.3.1 第一個示例
vim /root/first.yml
- hosts: all
remote_user: root
vars: httpd_port=80
tasks:
- name: install httpd
yum: name=httpd state=present
- name: install php
yum: name=php state=present
- name: start httpd
service: name=httpd state=started enabled=true
復制代碼
hosts 定義單個主機或組，vars定義變量，remote_user定義執(zhí)行命令的遠程用戶，tasks定義執(zhí)行哪些命令，handlers定義調用哪些處理器
vars(變量)：
-
變量命名： 字母數字下劃線組成，只能以字母開頭
-
變量種類：
-
facts（內置變量）
由遠程主機發(fā)回的主機屬性信息，這些信息被保存在ansible變量當中
例如：ansible 192.168.238.170 -m setup 來獲取遠程主機上的屬性信息，這些屬性信息保存在facts中
-
通過命令行傳遞
通過命令行傳遞：ansible-playbook test.yml --extra-vars “host=www user=tom“（如果劇本中已有此處定義的變量則會被覆蓋）
-
通過roles傳遞
-
主機變量
在/etc/ansible/hosts中定義
[web1]
192.168.1.1 name=haha
復制代碼
-
組變量
[group_name:vars]
foo=bar
復制代碼
主機：
/etc/abible/hosts 中指定的遠程主機，并用指定的屬性進行連接
ansible_ssh_port 連接遠程主機使用的端口
ansible_ssh_user 連接遠程主機使用的用戶
ansible_ssh_pass 連接遠程主機使用的密碼
復制代碼
cat /etc/ansible/hosts
[web1]
web1.hostname ansible_ssh_port=22 ansible_ssh_user=root ansible_ssh_pass=123
web2.hostname
復制代碼
5.3.2 第二個示例
vim /root/second.yml
- hosts: web1
remote_user: root
vars:
username: bob
password: 123
tasks:
- name: add user
user: name={{ username }} state=present
when: ansible_os_family == "Debian"
- name: set password
shell: echo {{ password }} |passwd --stdin {{ username }}
- name: install httpd php
yum: name={{ item }} state=present
with_items:
- httpd
- php
- name: add two users
user: name={{ item }} state=present groups={{ item.groups }}
with_items:
- { name: 'user1', groups: 'group1'}
- { name: 'user2', groups: 'group2'}
復制代碼
- 在playbook中調用變量的方式為{{ variable }}
- when語句用來條件測試
- ansible_os_family 是facts中內置的屬性信息 ansible_os_family的信息可以使用ansible all -m setup | grep ansible_os_family 查看
- 在task中調用內置的item變量；在某task后面使用with_items語句來定義元素列表
5.3.3 第三個示例
vim /root/third.yml
- hosts: web1
remote_user: root
vars:
httpd_port=80
tasks:
- name: install httpd
yum: name=httpd state=present
- name: install php
yum: name=php state=present
- name: copy config file
copy: src=/root/httpd.conf dest=/etc/httpd/conf/httpd.conf
notify: restart httpd
- name: start httpd
service: name=httpd state=started enabled=true
handlers:
- name: restart httpd
service: name=httpd state=restarted
復制代碼
上面的意思是copy中復制過去的文件跟遠程主機上的文件不同，就通過notify調用handlers，即重啟httpd服務。
handler是重啟服務是最通用的用法
5.3.4 第四個示例
vim /etc/ansible/hosts
[web1]
192.168.1.1 http_port=80
復制代碼
vim /root/httpd.conf
……
Listen {{ http_port }}
……
復制代碼
vim /root/fourth.yml
- hosts: web1
remote_user: root
vars:
httpd_port=80
tasks:
- name: install httpd
yum: name=httpd state=present
- name: copy config file
template: src=/root/httpd.conf dest=/etc/httpd/conf/httpd.conf
notify: restart httpd
- name: start httpd
service: name=httpd state=started enabled=true
handlers:
- name: restart httpd
service: name=httpd state=restarted
復制代碼
templates：用于生成文本文件（配置文件）
模板文件中可使用jinja2表達式，表達式要定義在{{ }}，也可以簡單地僅執(zhí)行變量替換
5.3.5 第五個示例
roles：roles用于實現“代碼復用”，roles以特定的層次型格式組織起來的playbook元素（variables, tasks, templates,handlers）；可被playbook以role的名字直接進行調用
roles的文件結構：
- files/：此角色中用到的所有文件均放置于此目錄中
- templates/： Jinja2模板文件存放位置
- tasks/：任務列表文件；可以有多個，但至少有一個叫做main.yml的文件
- handlers/：處理器列表文件；可以有多個，但至少有一個叫做main.yml的文件
- vars/：變量字典文件；可以有多個，但至少有一個叫做main.yml的文件
- meta/：此角色的特殊設定及依賴關系
mkdir /root/roles
cd /root/roles
mkdir -p web1/{files, templayes, tasks, handlers, vars, meta}
復制代碼
vim web1/vars/main.yml
user: tom
group: tom
http_port: 8080
復制代碼
vim web1/tasks/main.yml
- name: install httpd
yum: name=httpd state=present
- name: copy config file
template: src=httpd.conf dest=/etc/httpd/conf/httpd.conf
notify: restart httpd
tags: conf
- name: start httpd
service: name=httpd state=started enabled=true
這里的template指的是相對路徑-->web1/templates
tags可以在運行時指定標簽任務
復制代碼
vim web1/handlers/main.yml
handlers:
- name: restart httpd
service: name=httpd state=restarted
復制代碼
vim web1/templates/httpd.conf
……
Listen {{ http_port }}
……
復制代碼
定義一個調用roles文件
vim /root/web1.yml
- hosts: web1
remote_user: root
roles:
- web1
- { role:web2, http_port:8080 }
hosts：web1 指在/etc/ansible/hosts中定義的組，上面有定義
roles: web1 指的是當前目錄下的web1目錄，也可通過role傳遞變量， 也可調用多個role
這樣只需更改hosts的主機就可以實現不同主機的代碼重用了
