try ansible：use ping module

サーバ：192.168.2.211
対象：192.168.2.220

インストール直後、まずは、pingモジュールを試してみた。

[root@localhost ~]# ansible 192.168.2.220 -m ping

paramiko: The authenticity of host '192.168.2.220' can't be established.
The ssh-rsa key fingerprint is ********************************.
Are you sure you want to continue connecting (yes/no)?
yes
192.168.2.220 | FAILED => FAILED: No authentication methods available
[root@localhost ~]#

SSHの接続設定を行っていないからか
「No authentication methods available」と。

"--ask-pass"オプションを指定します。

[root@localhost ~]# ansible 192.168.2.220 -m ping -u root --ask-pass
SSH password:

paramiko: The authenticity of host '192.168.2.220' can't be established.
The ssh-rsa key fingerprint is ********************************.
Are you sure you want to continue connecting (yes/no)?
yes
192.168.2.220 | FAILED => FAILED: Authentication failed.
[root@localhost ~]#

あ、パスワードを間違えた。

もう一度

[root@localhost ~]# ansible 192.168.2.220 -m ping -u root --ask-pass
SSH password:

paramiko: The authenticity of host '192.168.2.220' can't be established.

yes

[root@localhost ~]#

今度は、成功しました。

あ、でも、ファイルがないって怒られてます。。。
また、次回見てみます。
