Ansible Documentation
Python 3 Support参考
こちらの記事で CentOS 7.6.1810 に Ansible をインストールしました。今回は Ubuntu 19.04 desktop に Ansible をインストールします。基本的な流れは CentOS 7.6.1810 のときと同じですが、次の差異があります。- CentOS は RedHat 系だが Ubuntu は Debian 系
- CentOS は python2 が標準だが、Ubuntu は python3 が標準
- CentOS は Ansible のインストール時に sshpass コマンドがインストールされるが、Ubuntu は別途インストールが必要
- Ansible のインストール時に使用する pip3 コマンドは別途インストールが必要
- 作業用アカウント ansibleman は Ubuntu 19.04 をインストールするときに作成する
ansibleman@ubuntu-pc:~$ python --version
Command 'python' not found, but can be installed with:
sudo apt install python3 # version 3.7.3-1, or
sudo apt install python # version 2.7.16-1
sudo apt install python-minimal # version 2.7.16-1
You also have python3 installed, you can run 'python3' instead.
ansibleman@ubuntu-pc:~$
ansibleman@ubuntu-pc:~$ python3 --version
Python 3.7.3
ansibleman@ubuntu-pc:~$
ansibleman@ubuntu-pc:~$ pip3
Command 'pip3' not found, but can be installed with:
sudo apt install python3-pip
ansibleman@ubuntu-pc:~$ ToDo
作用の流れです。- pip3 コマンドのインストール
- pip3 コマンドがインストールされたことを確認
- ansible の確認
- &nbps;ansible がインストールされたことの確認
- ansible コマンドのバージョン確認
- ssh 接続時のフィンガープリントを記録しないよう設定
- 作業用ディレクトリ ansible の作成
投入コマンド
すべて、インストール時に作成したアカウント ansibleman で作業します。- sudo apt install -y python3-pip
- pip3
- pip3 install ansible
- pip3 show ansible
- ansible --version
- sudo apt install -y sshpass
- mkdir ~/.ssh
- chmod 700 ~/.ssh
- vi ~/.ssh/config
- Host *
- StrictHostKeyChecking no
- UserKnownHostsFile=/dev/null
- chmod 600 ~/.ssh/config
- mkdir ~/ansible
