はじめに
構成管理ツールの一つである「Ansible」をインストールする。
システム環境
- Ansibleサーバ(ansibleserver)
- OS：CentOS 7.9
- Ansible：2.9.27
- Ansible管理対象(ansibleclient1,2)
- OS：CentOS 7.9
インストール手順
Ansible用yumリポジトリのインストール
CentOSの標準リポジトリにはansibleが存在しない。まずはAnsible用yumリポジトリ「centos-release-ansible-29.noarch」をインストールする。
ansibleserverにて実行する。
