Ansible 運維自動化 ( 配置管理工具 ),ansible配置管理


Ansible 運維自動化 ( 配置管理工具 ),ansible配置管理



簡介:

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 系統的配置管理、應用部署、執行特定任務的開源平台,是 AnsibleWorks 公司名下的項目,該公司由 Cobbler 及 Func 的作者於 2012 年創建成立。

Ansible 基於 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 環境,被控端無需做任何操作。
>> 默認使用 SSH(Secure Shell)協議對設備進行管理。
>> 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、狀態管理。
>> 對雲計算平台、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 平台。

Ansible 與 SaltStack

>> 最大的區別是 Ansible 無需在被監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行或下發配置。
>> 相同點是都具備功能強大、靈活的系統管理、狀態配置,都使用 YAML 格式來描述配置,兩者都提供豐富的模板及 API,對雲計算平台、大數據都有很好的支持。

一、安裝 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 用來配置被管理的機器;roles 是一個目錄,playbook 將使用它
ansible.cfg hosts roles

1、Ansible 管理機與被管理機做秘鑰認證

shell > ssh-keygen        # 生成秘鑰
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 [email protected]
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 [email protected]"     # 將公鑰寫入被管理機
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.
[email protected]'s password: 
Now try logging into the machine, with "ssh '-p 22 [email protected]'", and check in:

.ssh/authorized_keys

to make sure we haven't added extra keys that you weren't expecting.

2、hosts 文件添加被管理機

shell > > /etc/ansible/hosts
shell > vim /etc/ansible/hosts

[Client]

192.168.12.129

三、測試 Ansible

shell > ansible Client -m ping     # 操作 Client 組 ( all 為操作 hosts 文件中所有主機 ),-m 指定執行 ping 模塊,下面是返回結果
192.168.12.129 | SUCCESS => {
"changed": false, 
"ping": "pong"
}

# -i 指定 hosts 文件位置
# -u username 指定 SSH 連接的用戶名
# -k 指定遠程用戶密碼
# -f 指定並發數
# -s 如需要 root 權限執行時使用 ( 連接用戶不是 root 時 )
# -K -s 時,-K 輸入 root 密碼

四、附加

1、/etc/ansible/hosts 文件

## Ansible 定義主機、組規則的配置文件

shell > vim /etc/ansible/hosts

www.abc.com     # 定義域名

192.168.1.100   # 定義 IP

192.168.1.150:37268   # 指定端口號

[WebServer]           # 定義分組

192.168.1.10
192.168.1.20
192.168.1.30

[DBServer]            # 定義多個分組

192.168.1.50
192.168.1.60

Monitor ansible_ssh_port=12378 ansible_ssh_host=192.168.1.200   # 定義別名

# ansible_ssh_host 連接目標主機的地址

# ansible_ssh_port 連接目標主機的端口,默認 22 時無需指定

# ansible_ssh_user 連接目標主機默認用戶

# ansible_ssh_pass 連接目標主機默認用戶密碼

# ansible_ssh_connection 目標主機連接類型,可以是 local 、ssh 或 paramiko

# ansible_ssh_private_key_file 連接目標主機的 ssh 私鑰

# ansible_*_interpreter 指定采用非 Python 的其他腳本語言,如 Ruby 、Perl 或其他類似 ansible_python_interpreter 解釋器

[webservers]         # 主機名支持正則描述

www[01:50].example.com

[dbservers]

db-[a:f].example.com

2、Ansible 常用模塊學習

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

>> 遠程命令模塊( command / script / shell )

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。

例:

shell > ansible Client -m command -a "free -m"               # 查看 Client 分組主機內存使用情況

script 的功能是在遠程主機執行主控端存儲的 shell 腳本文件,相當於 scp + shell 組合。

例:

shell > ansible Client -m script -a "/home/test.sh 12 34"    # 遠程執行本地腳本

shell 的功能是執行遠程主機上的 shell 腳本文件,支持管道符。

例:

shell > ansible Client -m shell -a "/home/test.sh"           # 執行遠程腳本

>> copy 模塊(實現主控端向目標主機拷貝文件,類似於 scp 功能)

例:

shell > ansible Client -m copy -a "src=/home/test.sh desc=/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

>> stat 模塊(獲取遠程文件狀態信息,atime/ctime/mtime/md5/uid/gid 等信息)

例:

shell > ansible Client -m stat -a "path=/etc/syctl.conf"

>> get_url 模塊(實現在遠程主機下載指定 URL 到本地,支持 sha256sum 文件校驗)

例:

shell > ansible Client -m get_utl -a "url=http://www.baidu.com dest=/tmp/index.html mode=0440 force=yes"

>> yum 模塊(軟件包管理)

例:

shell > ansible Client -m yum -a "name=curl state=latest"

>> cron 模塊(遠程主機 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 模塊(遠程主機分區掛載)

例:

shell > ansible Client -m mount -a "name=/mnt/data src=/dev/sd0 fstype=ext4 opts=ro state=present"

>> service 模塊(遠程主機系統服務管理)

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 服務模塊(遠程主機用戶管理)

例:

shell > ansible Client -m user -a "name=wang comment='user wang'"

shell > ansible Client -m user -a "name=wang state=absent remove=yes"    # 添加刪除用戶

五、Ansible-playbook

# 使用 Ansible-playbook 可以完成一組復雜的動作,例如部署環境、搭建服務、修改配置等。

簡單示例:

shell > vim /etc/ansible/playbook.yml    # 將遠程主機IP地址寫入文件中保存

---
- hosts: Client
remote_user: root
tasks:
- name: Save IP To info.txt
shell: "ifconfig eth0 | awk -F '[ :]'+ '/inet addr/{print $4}' > ~/info.txt"

# hosts        指定執行操作主機
# remote_user  指定執行用戶
# tasks        指明有哪些動作
# name         動作描述
# shell        模塊,後面為具體指令

Playbook 實戰:

一、目錄結構

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  此文件為 ansible 的主配置文件
## hosts        用於定義主機組
## roles        定義不同的角色
## install_zabbix_agent.yml  用於安裝 zabbix_agent 的引導文件
## delete_zabbix_agent.yml   刪除已安裝的 zabbix_agent 的引導文件

    └── 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 為一個角色,用於安裝 zabbix_agent

## file      目錄:用於存放將要拷貝到遠程主機的安裝包等
## tasks     目錄:將要執行的所有任務,如果比較復雜,可以單獨定義不同的任務,最後在 main.yml 文件中引用即可
## templates 目錄:模板目錄,這裡存放著一些可變的文件,即:每台主機上的這些文件中的內容都不完全相同
## vars      目錄:用於存放變量

## 這是一個比較簡單的結構,其實一個角色中還可以有 meta 、handlers 等

二、Playbook 安裝軟件需要的步驟

1、定義 hosts( 給哪些主機安裝軟件 )

shell > vim /etc/ansible/hosts

[mini]

129.139.153.78:16283
155.139.190.94:12573

2、定義入口文件 install_zabbix_agent.yml

shell > vim /etc/ansible/install_zabbix_agent.yml

---
- hosts: mini
  roles:
  - install_zabbix_agent

## 可以看到將要安裝的主機組為 mini 組,角色為 install_zabbix_agent

3、定義角色 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     目錄,存放編譯安裝過的 zabbix_agent 目錄的壓縮文件,用於拷貝到遠程主機
## 建立 tasks     目錄,用於編寫將要執行的任務
## 建立 templates 目錄,用於存放可變的模板文件
## 建立 vars      目錄,用於存放變量信息
shell > cat /etc/ansible/roles/install_zabbix_agent/tasks/main.yml

#       Multiple Alias parameters may be present. Multiple parameters with the same Alias key are not allowed.
#       Different Alias keys may reference the same item key.
#       For example, to retrieve the ID of user 'zabbix':
#       Alias=zabbix.userid:vfs.file.regexp[/etc/passwd,^zabbix:.:([0-9]+),,,,\1]
#       Now shorthand key zabbix.userid may be used to retrieve data.
#       Aliases can be used in HostMetadataItem but not in HostnameItem parameters.

# Mandatory: no
# Default:
# Include=

# Include=/usr/local/etc/zabbix_agentd.userparams.conf
# Include=/usr/local/etc/zabbix_agentd.conf.d/
# Include=/usr/local/etc/zabbix_agentd.conf.d/*.conf

####### USER-DEFINED MONITORED PARAMETERS #######

### Option: UnsafeUserParameters
#       Allow all characters to be passed in arguments to user-defined parameters.
#       0 - do not allow
#       1 - allow
#
# Mandatory: no
# Range: 0-1
# Default:
UnsafeUserParameters=1

### Option: UserParameter
#       User-defined parameter to monitor. There can be several user-defined parameters.

### Option: LoadModulePath
#       Full path to location of agent modules.
#       Default depends on compilation options.
#
# Mandatory: no
# Default:
# LoadModulePath=${libdir}/modules

### Option: LoadModule
#       Module to load at agent startup. Modules are used to extend functionality of the agent.
#       Format: LoadModule=<module.so>
#       The modules must be located in directory specified by LoadModulePath.
#       It is allowed to include multiple LoadModule parameters.
