一、Ansible简介
1.ansible是什么？
ansible是新出现的自动化运维工具，基于Python开发，集合了众多运维工具（puppet、chef、func、fabric）的优点，实现了批量系统配置、批量程序部署、批量运行命令等功能。
简单来说ansible是一种架构，本身没有批量部署的能力批量部署能力是由模块来提供的！而且不需要在被控制的主机上安装任何东西，因为ansible是通过ssh协议来与远程主机通讯的
2.ansible特点
- 部署简单，只需在主控端部署Ansible环境，被控端无需做任何操作；
- 默认使用SSH协议对设备进行管理；
- 有大量常规运维操作模块，可实现日常绝大部分操作；
- 配置简单、功能强大、扩展性强；
- 支持API及自定义模块，可通过Python轻松扩展；
- 通过Playbooks来定制强大的配置、状态管理；
- 轻量级，无需在客户端安装agent，更新时，只需在操作机上进行一次更新即可；
3.ansible架构
主要模块
- Ansible：ansible核心程序
- HostInventory：主机清单，记录由Ansible管理的主机信息，包括端口、密码、ip等。
- Playbooks：剧本，YAML格式文件，多个任务定义在一个文件中，定义主机需要调用哪些模块来完成的功能。
- CoreModules：核心模块，主要操作是通过调用核心模块来完成管理任务。
- CustomModules：自定义模块，完成核心模块无法完成的功能，支持多种语言。
- ConnectionPlugins：连接插件，Ansible和Host通信使用
工作流程
- 用户使用ansible程序
- ansible查看主机清单（HostInventory）
- ansible知道要控制的都有谁了，开始调用模块、剧本或角色
- 通过连接模块连接远程主机，部署任务开始
命令执行过程
- 加载自己的配置文件，默认/etc/ansible/ansible.cfg；
- 查找对应的主机配置文件，找到要执行的主机或者组；
- 加载自己对应的模块文件，如 command；
- 通过ansible将模块或命令生成对应的临时py文件(python脚本)， 并将该文件传输至远程服务器；
- 对应生成用户的家目录的.ansible/tmp/XXX/XXX.PY文件；
- 给文件 +x 执行权限；
- 执行并返回结果；
- 删除临时py文件，sleep 0退出；
二、Ansible 配置
1 安装ansible
2 目录结构
安装目录如下(yum安装)：
配置文件目录：/etc/ansible/
执行文件目录：/usr/bin/
Lib库依赖目录：/usr/lib/pythonX.X/site-packages/ansible/
Help文档目录：/usr/share/doc/ansible-X.X.X/
Man文档目录：/usr/share/man/man1/
3 ansible配置文件
ansible 的配置文件为/etc/ansible/ansible.cfg，ansible 有许多参数，下面我们列出一些常见的参数：
inventory = /etc/ansible/hosts #这个参数表示资源清单inventory文件的位置
library = /usr/share/ansible #指向存放Ansible模块的目录，支持多个目录方式，只要用冒号（：）隔开就可以
forks = 5 #并发连接数，默认为5
sudo_user = root #设置默认执行命令的用户
remote_port = 22 #指定连接被管节点的管理端口，默认为22端口，建议修改，能够更加安全
host_key_checking = False #设置是否检查SSH主机的密钥，值为True/False。关闭后第一次连接不会提示配置实例
timeout = 60 #设置SSH连接的超时时间，单位为秒
log_path = /var/log/ansible.log #指定一个存储ansible日志的文件（默认不记录日志）
4 ansible主机清单
有多种定义方式：
1、 直接指明主机地址或主机名：
192.168.100.10
2、定义一个组名，把主机加进去，当然也可以用通配符来匹配！
[test]
192.168.100.[1:3]0
....
...
...
"/etc/ansible/hosts" 57L, 1169C 1,1
5 ansible颜色
Ansible执行的时候根据结果会显示为绿色（成功执行），黄色（成功伴随状态改变）和红色（执行失败）等颜色，颜色的显示与changed的状态相关联，并可以在ansible.cfg中进行定制颜色的设定。
三、Ansible 常用命令
1 ansible 命令集
/usr/bin/ansible Ansibe AD-Hoc 临时命令执行工具，常用于临时命令的执行
/usr/bin/ansible-doc Ansible 模块帮助文档
/usr/bin/ansible-galaxy 下载/上传优秀代码或Roles模块 的官网平台
/usr/bin/ansible-playbook Ansible 任务集编排工具
/usr/bin/ansible-pull Ansible远程执行命令的工具，拉取配置而非推送配置（使用较少，海量机器时使用，对运维的架构能力要求较高）
/usr/bin/ansible-vault Ansible 文件加密工具
/usr/bin/ansible-console Ansible基于Linux Consoble界面可与用户交互的命令执行工具
其中，我们比较常用的是/usr/bin/ansible和/usr/bin/ansible-playbook。
2 ansible-doc 命令
[root@ansible ~]# ansible-doc
Usage: ansible-doc [options] [module...]
Options:
-h, --help show this help message and exit # 显示命令参数API文档
-l, --list List available modules #列出可用的模块
-M MODULE_PATH, --module-path=MODULE_PATH #指定模块的路径
specify path(s) to module library (default=None)
-s, --snippet Show playbook snippet for specified module(s) #显示playbook制定模块的用法
-v, --verbose verbose mode (-vvv for more, -vvvv to enable # 显示ansible-doc的版本号查看模块列表：
connection debugging)
--version show program's version number and exit
例如：
[root@ansible ansible]# ansible-doc -l |grep nginx
nginx_status_info Retrieve information on nginx stat...
nginx_status_facts Retrieve nginx status facts
[root@ansible ansible]# ansible-doc -s nginx_status_info
- name: Retrieve information on nginx status.
nginx_status_info:
timeout: # HTTP connection timeout in seconds.
url: # (required) URL of the nginx status.
3 ansible 命令格式
命令的具体格式如下：
ansible host-pattern -m 模块名 -a ‘参数’
通过ansible -h查看
[root@ansible ansible]# ansible -h
-a MODULE_ARGS #模块的参数，如果执行默认COMMAND的模块，即是命令参数，如： “date”，“pwd”等等
-k，--ask-pass #ask for SSH password。登录密码，提示输入SSH密码而不是假设基于密钥的验证
--ask-su-pass #ask for su password。su切换密码
-K，--ask-sudo-pass #ask for sudo password。提示密码使用sudo，sudo表示提权操作
--ask-vault-pass #ask for vault password。假设我们设定了加密的密码，则用该选项进行访问
-B SECONDS #后台运行超时时间
-C #模拟运行环境并进行预运行，可以进行查错测试
-c CONNECTION #连接类型使用
-f FORKS #并行任务数，默认为5
-i INVENTORY #指定主机清单的路径，默认为/etc/ansible/hosts
--list-hosts #查看有哪些主机组
-m MODULE_NAME #执行模块的名字，默认使用 command 模块，所以如果是只执行单一命令可以不用 -m参数
-o #压缩输出，尝试将所有结果在一行输出，一般针对收集工具使用
-S #用 su 命令
-R SU_USER #指定 su 的用户，默认为 root 用户
-s #用 sudo 命令
-U SUDO_USER #指定 sudo 到哪个用户，默认为 root 用户
-T TIMEOUT #指定 ssh 默认超时时间，默认为10s，也可在配置文件中修改
-u REMOTE_USER #远程用户，默认为 root 用户
-v #查看详细信息，同时支持-vvv，-vvvv可查看更详细信息
4 ssh免密登录
原理
实验
#1.生成私钥
[root@ansible ~]# ssh-keygen
#2.向主机分发私钥
[root@ansible ~]# ssh-copy-id root@192.168.100.10
[root@ansible ~]# ssh-copy-id root@192.168.100.20
四、Ansible 常用模块
1 ping模块
[root@ansible ~]# ansible 192.168.100.10 -m ping
192.168.100.10 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/bin/python"
},
"changed": false,
"ping": "pong"
}
这样就说明我们的主机是连通状态的。接下来的操作才可以正常进行。
2 shell模块
shell模块很常用，它可以在远程主机上调用shell解释器运行命令
[root@ansible ~]# head -10 /etc/ansible/hosts
[test]
192.168.100.[1:3]0
[wsr]
192.168.100.10 http_port=81
192.168.100.20 http_port=82
[wsr:vars]
nodename=mail
domainname=edu
[root@ansible ~]# ansible wsr -m shell -a 'ls -l'

# 总结
<font color=#999AAA >提示：
3 command模块
这个模块可以直接在远程主机上执行命令，并将结果返回本主机。
命令模块接受命令名称，后面是空格分隔的列表参数。给定的命令将在所有选定的节点上执行。它不会通过shell进行处理，比如$HOME和操作如"<"，">"，"|"，";"，"&"工作（需要使用（shell）模块实现这些功能）。
下面来看一看该模块下常用的几个命令：
- chdir # 在执行命令之前，先切换到该目录 executable # 切换shell来执行命令，需要使用命令的绝对路径
- free_form # 要执行的Linux指令，一般使用Ansible的-a参数代替。
- creates # 一个文件名，当这个文件存在，则该命令不执行,可以
用来做判断 - removes # 一个文件名，这个文件不存在，则该命令不执行
[root@ansible ~]# ansible wsr -m command -a 'chdir=/data ls'

4 copy模块
这个模块用于将文件复制到远程主机，同时支持给定内容生成文件和修改权限等。
其相关选项如下：
- src #被复制到远程主机的本地文件。可以是绝对路径，也可以是相对路径。如果路径是一个目录，则会递归复制，用法类似于"rsync"
- content #用于替换"src"，可以直接指定文件的值
- dest #必选项，将源文件复制到的远程主机的绝对路径
- backup #当文件内容发生改变后，在覆盖之前把源文件备份，备份文件包含时间信息
- directory_mode #递归设定目录的权限，默认为系统默认权限
- force #当目标主机包含该文件，但内容不同时，设为"yes"，表示强制覆盖；设为"no"，表示目标主机的目标位置不存在该文件才复制。默认为"yes"
- others #所有的 file 模块中的选项可以在这里使用
其中src，dest，backup，mode用的较多
复制
[root@ansible ~]# touch 2021710
[root@ansible ~]# ansible wsr -m copy -a 'src=2021710 dest=/data/2021710'

6 file模块
该模块主要用于设置文件的属性，比如创建文件、创建链接文件、删除文件等。
下面是一些常见的命令：
force #需要在两种情况下强制创建软链接，一种是源文件不存在，但之后会建立的情况下；另一种是目标软链接已存在，需要先取消之前的软链，然后创建新的软链，有两个选项：yes|no
group #定义文件/目录的属组。后面可以加上mode：定义文件/目录的权限
owner #定义文件/目录的属主。后面必须跟上path：定义文件/目录的路径
recurse #递归设置文件的属性，只对目录有效，后面跟上src：被链接的源文件路径，只应用于state=link的情况
dest #被链接到的路径，只应用于state=link的情况
state #状态，有以下选项：
directory：如果目录不存在，就创建目录
file：即使文件不存在，也不会被创建
link：创建软链接
hard：创建硬链接
touch：如果文件不存在，则会创建一个新的文件，如果文件或目录已存在，则更新其最后修改时间
absent：删除目录、文件或者取消链接文件
创建文件夹

7 cron模块
该模块适用于管理cron计划任务的。
其使用的语法跟我们的crontab文件中的语法一致
- day= #日应该运行的工作( 1-31, *, */2, )
- hour= # 小时 ( 0-23, *, */2, )
- minute= #分钟( 0-59, *, */2, )
- month= # 月( 1-12, *, /2, )
- weekday= # 周 ( 0-6 for Sunday-Saturday, )
- job= #指明运行的命令是什么
- name= #定时任务描述
- reboot # 任务在重启时运行，不建议使用，建议使用special_time
- special_time
#特殊的时间范围，参数：reboot（重启时），annually（每年），monthly（每月），weekly（每周），daily（每天），hourly（每小时） - state #指定状态，present表示添加定时任务，也是默认设置，absent表示删除定时任务
- user # 以哪个用户的身份执行

常用的选项如下：
- gid= #设置组的GID号
- name= #指定组的名称
- state= #指定组的状态，默认为创建，设置值为absent为删除

[root@ansible tmp]# cat df.sh
#!/bin/bash
date >> /tmp/disk_total.log

11 setup模块
通过调用facts(facts就是变量，内建变量)组件来收集主机信息，如vcpu个数，内存大小等…
可以使用filter来查看指定信息,调用后返回很多对应主机的信息，在后面的操作中可以根据不同的信息来做不同的操作
如redhat系列用yum安装，而debian系列用apt来安装软件。

12 service 模块
该模块用于服务程序的管理。
其主要选项如下：
- arguments #命令行提供额外的参数
- enabled #设置开机启动。
- name= #服务名称
- runlevel #开机启动的级别，一般不用指定。
- sleep #在重启服务的过程中，是否等待。如在服务关闭以后等待2秒再启动。(定义在剧本中。)
- state #有四种状态，分别为：started—>启动服务， stopped—>停止服务，
- restarted—>重启服务， reloaded—>重载配置
