Ansibleの構成と導入
ツール名
紹介する
Chef
Ruby作成、C/Sアーキテクチャを採用し、構成にはGit依存、Recipeスクリプト作成規範が必要であり、良好なプログラミング経験が必要である.
Ansible
Python作成、Clientなし、モジュール化配置管理、Playbookスクリプト作成規範を採用し、使いやすく、中小規模の迅速な配置に適している.
Saltstack
Python作成、C/Sアーキテクチャ、モジュール化配置管理、YAMLスクリプト作成規範を採用し、内蔵非同期ファイルサーバーはクライアントファイルのサービス速度を速めることができ、大規模なクラスタ配置に適しているが、クライアントをインストールする必要がある.

Ansibleの利点と適用シーン
メリット:

軽量レベルクライアントなし(Agentless);

オープンソースは無料で、学習コストが低く、迅速に手に入る.

playbookをコア構成アーキテクチャとして使用し、同意したスクリプトフォーマットのバッチ化配置;

完全なモジュール化拡張、現在の主流の開発環境をサポートする.

の強力な安定性と互換性.

活発な公式コミュニティ問題の討論は、troubleshootingとdebug問題を便利にする.

Ansible配合virtualenvインストール構成
python独自のpython virtualenvツールを使用してPython 3を分離します.6、Ansible2.5およびシステムの他のpython依存環境.
Ansible取付方式
1.yumワンタッチインストール(推奨しない)

[root@ansible ~]# yum install -y ansible
#     ，

2.Gitソースコードのインストール(推奨)

[root@ansible ~]# yum install -y git      #       git  ，          
[root@ansible ~]# git clone https://github.com/ansible/ansible.git

Ansible2.5+Python3.6インストール手順
