本文来源个人微博,本文主要介绍了配置管理工具Ansible的安装和配置 ,希望对您的学习有帮助。

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:

1.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。

2. 默认使用 SSH(Secure Shell)协议对设备进行管理。

3.主从集中化管理。

4. 配置简单、功能强大、扩展性强。

5. 支持 API 及自定义模块,可通过 Python 轻松扩展。

6. 通过 Playbooks 来定制强大的配置、状态管理。

7. 对云计算平台、大数据都有很好的支持。

8.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

1. 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。

2. 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

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
