Ansible 运维自动化 ( 配置管理工具 )
简介：
当下有许多的运维自动化工具( 配置管理 )，例如：Ansible、SaltStack、Puppet、Fabric 等。
Ansible 一种集成 IT 系统的配置管理、应用部署、执行特定任务的开源平台，是 AnsibleWorks 公司名下的项目，该公司由 Cobbler 及 Func 的作者于 2012 年创建成立。
Ansible 基于 Python 语言实现，由 Paramiko 和 PyYAML 两个关键模块构建。
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（Secure Shell）协议对设备进行管理。
>> 主从集中化管理。
>> 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。
>> 对云计算平台、大数据都有很好的支持。
>> 提供一个功能强大、操作性强的 Web 管理界面和 REST API 接口 ---- AWX 平台。
Ansible 与 SaltStack
>> 最大的区别是 Ansible 无需在被监控主机部署任何客户端代理，默认通过 SSH 通道进行远程命令执行或下发配置。
>> 相同点是都具备功能强大、灵活的系统管理、状态配置，都使用 YAML 格式来描述配置，两者都提供丰富的模板及 API，对云计算平台、大数据都有很好的支持。
一、安装 Ansible
shell > yum -y install ansible
二、配置 Ansible
shell > ls /etc/ansible # ansible.cfg 是 Ansible 工具的配置文件；hosts 用来配置被管理的机器；roles 是一个目录，playbook 将使用它 ansible.cfg hosts roles
1、Ansible 管理机与被管理机做秘钥认证
shell > ssh-keygen # 生成秘钥 Generating public/private rsa key pair. Enter file in which to save the key (/root/.ssh/id_rsa): Created directory '/root/.ssh'. Enter passphrase (empty for no passphrase): Enter same passphrase again: Your identification has been saved in /root/.ssh/id_rsa. Your public key has been saved in /root/.ssh/id_rsa.pub. The key fingerprint is: ea:11:72:ea:d2:d1:fa:1c:e0:df:4f:b0:98:31:be:fe root@localhost.localdomain The key's randomart image is: +--[ RSA 2048]----+ | | | | | | | | | o.= S | | ..*.B o | | .ooB . . | | ..o+ = . | | ..oB.E.. | +-----------------+ shell > ssh-copy-id -i ~/.ssh/id_rsa.pub "-p 22 root@192.168.12.129" # 将公钥写入被管理机 The authenticity of host '192.168.12.129 (192.168.12.129)' can't be established. RSA key fingerprint is f0:9e:01:73:a4:bf:14:10:ac:46:a9:48:cd:c5:d8:1c. Are you sure you want to continue connecting (yes/no)? yes Warning: Permanently added '192.168.12.129' (RSA) to the list of known hosts. root@192.168.12.129's password: Now try logging into the machine, with "ssh '-p 22 root@192.168.12.129'", and check in: .ssh/authorized_keys to make sure we haven't added extra keys that you weren't expecting.
2、hosts 文件添加被管理机
shell > > /etc/ansible/hosts shell > vim /etc/ansible/hosts [Client] 192.168.12.129
三、测试 Ansible
shell > ansible Client -m ping # 操作 Client 组 ( all 为操作 hosts 文件中所有主机 )，-m 指定执行 ping 模块，下面是返回结果
192.168.12.129 | SUCCESS => {
"changed": false,
"ping": "pong"
}
# -i 指定 hosts 文件位置
# -u username 指定 SSH 连接的用户名
# -k 指定远程用户密码
# -f 指定并发数
# -s 如需要 root 权限执行时使用 ( 连接用户不是 root 时 )
# -K -s 时，-K 输入 root 密码
四、附加
1、/etc/ansible/hosts 文件
## Ansible 定义主机、组规则的配置文件
shell > vim /etc/ansible/hosts www.abc.com # 定义域名 192.168.1.100 # 定义 IP 192.168.1.150:37268 # 指定端口号 [WebServer] # 定义分组 192.168.1.10 192.168.1.20 192.168.1.30 [DBServer] # 定义多个分组 192.168.1.50 192.168.1.60 Monitor ansible_ssh_port=12378 ansible_ssh_host=192.168.1.200 # 定义别名 # ansible_ssh_host 连接目标主机的地址 # ansible_ssh_port 连接目标主机的端口，默认 22 时无需指定 # ansible_ssh_user 连接目标主机默认用户 # ansible_ssh_pass 连接目标主机默认用户密码 # ansible_ssh_connection 目标主机连接类型，可以是 local 、ssh 或 paramiko # ansible_ssh_private_key_file 连接目标主机的 ssh 私钥 # ansible_*_interpreter 指定采用非 Python 的其他脚本语言，如 Ruby 、Perl 或其他类似 ansible_python_interpreter 解释器 [webservers] # 主机名支持正则描述 www[01:50].example.com [dbservers] db-[a:f].example.com
2、Ansible 常用模块学习
shell > ansible-doc -l # 列出 Ansible 支持的模块 shell > ansible-doc ping # 查看该模块帮助信息
>> 远程命令模块（ command / script / shell ）
command 作为 Ansible 的默认模块，可以运行远程权限范围所有的 shell 命令，不支持管道符。
例：
shell > ansible Client -m command -a "free -m" # 查看 Client 分组主机内存使用情况
script 的功能是在远程主机执行主控端存储的 shell 脚本文件，相当于 scp + shell 组合。
例：
shell > ansible Client -m script -a "/home/test.sh 12 34" # 远程执行本地脚本
shell 的功能是执行远程主机上的 shell 脚本文件，支持管道符。
例：
shell > ansible Client -m shell -a "/home/test.sh" # 执行远程脚本
>> copy 模块（实现主控端向目标主机拷贝文件，类似于 scp 功能）
例：
shell > ansible Client -m copy -a "src=/home/test.sh desc=/tmp/ owner=root group=root mode=0755" # 向 Client 组中主机拷贝 test.sh 到 /tmp 下，属主、组为 root ，权限为 0755
>> stat 模块（获取远程文件状态信息，atime/ctime/mtime/md5/uid/gid 等信息）
例：
shell > ansible Client -m stat -a "path=/etc/syctl.conf"
>> get_url 模块（实现在远程主机下载指定 URL 到本地，支持 sha256sum 文件校验）
例：
shell > ansible Client -m get_utl -a "url=http://www.baidu.com dest=/tmp/index.html mode=0440 force=yes"
>> yum 模块（软件包管理）
例：
shell > ansible Client -m yum -a "name=curl state=latest"
>> cron 模块（远程主机 crontab 配置）
例：
shell > ansible Client -m cron -a "name='check dirs' hour='5,2' job='ls -alh > /dev/null'"
效果：
#Ansible: check dirs * 5,2 * * * ls -alh > /dev/null
>> mount 模块（远程主机分区挂载）
例：
shell > ansible Client -m mount -a "name=/mnt/data src=/dev/sd0 fstype=ext4 opts=ro state=present"
>> service 模块（远程主机系统服务管理）
例：
shell > ansible Client -m service -a "name=nginx state=stoped" shell > ansible Client -m service -a "name=nginx state=restarted" shell > ansible Client -m service -a "name=nginx state=reloaded"
>> user 服务模块（远程主机用户管理）
例：
shell > ansible Client -m user -a "name=wang comment='user wang'" shell > ansible Client -m user -a "name=wang state=absent remove=yes" # 添加删除用户
五、Ansible-playbook
# 使用 Ansible-playbook 可以完成一组复杂的动作，例如部署环境、搭建服务、修改配置等。
简单示例：
shell > vim /etc/ansible/playbook.yml # 将远程主机IP地址写入文件中保存
---
- hosts: Client
remote_user: root
tasks:
- name: Save IP To info.txt
shell: "ifconfig eth0 | awk -F '[ :]'+ '/inet addr/{print $4}' > ~/info.txt"
# hosts 指定执行操作主机
# remote_user 指定执行用户
# tasks 指明有哪些动作
# name 动作描述
# shell 模块，后面为具体指令
Playbook 实战：
一、目录结构
shell > cd /etc/ansible/ ; tree .
.
├── ansible.cfg
├── delete_zabbix_agent.yml
├── hosts
├── install_zabbix_agent.yml
└── roles
├── delete_zabbix_agent
│ ├── tasks
│ │ └── main.yml
│ └── vars
│ └── main.yml
└── install_zabbix_agent
├── files
│ └── zabbix-2.4.5.tar.gz
├── tasks
│ └── main.yml
├── templates
│ ├── zabbix_agentd
│ └── zabbix_agentd.conf
└── vars
└── main.yml
## ansible.cfg 此文件为 ansible 的主配置文件
## hosts 用于定义主机组
## roles 定义不同的角色
## install_zabbix_agent.yml 用于安装 zabbix_agent 的引导文件
## delete_zabbix_agent.yml 删除已安装的 zabbix_agent 的引导文件
└── install_zabbix_agent
├── files
│ └── zabbix-2.4.5.tar.gz
├── tasks
│ └── main.yml
├── templates
│ ├── zabbix_agentd
│ └── zabbix_agentd.conf
└── vars
└── main.yml
## 其中，install_zabbix_agent 为一个角色，用于安装 zabbix_agent
## file 目录：用于存放将要拷贝到远程主机的安装包等
## tasks 目录：将要执行的所有任务，如果比较复杂，可以单独定义不同的任务，最后在 main.yml 文件中引用即可
## templates 目录：模板目录，这里存放着一些可变的文件，即：每台主机上的这些文件中的内容都不完全相同
## vars 目录：用于存放变量
## 这是一个比较简单的结构，其实一个角色中还可以有 meta 、handlers 等
二、Playbook 安装软件需要的步骤
1、定义 hosts（ 给哪些主机安装软件 ）
shell > vim /etc/ansible/hosts [mini] 129.139.153.78:16283 155.139.190.94:12573
2、定义入口文件 install_zabbix_agent.yml
shell > vim /etc/ansible/install_zabbix_agent.yml --- - hosts: mini roles: - install_zabbix_agent ## 可以看到将要安装的主机组为 mini 组，角色为 install_zabbix_agent
3、定义角色 install_zabbix_agent
shell > tree /etc/ansible/roles/install_zabbix_agent/
├── files
│ └── zabbix-2.4.5.tar.gz
├── tasks
│ └── main.yml
├── templates
│ ├── zabbix_agentd
│ └── zabbix_agentd.conf
└── vars
└── main.yml
## 建立 files 目录，存放编译安装过的 zabbix_agent 目录的压缩文件，用于拷贝到远程主机
## 建立 tasks 目录，用于编写将要执行的任务
## 建立 templates 目录，用于存放可变的模板文件
## 建立 vars 目录，用于存放变量信息
shell > cat /etc/ansible/roles/install_zabbix_agent/tasks/main.yml
