生成 Ansible 配置文件的方法
Ansible 提供了 ansible-config 工具来生成配置文件模板，适用于不同版本的需求。
Ansible 2.12 及更高版本
使用以下命令生成包含所有默认设置（注释状态）的配置文件模板：
ansible-config init --disabled > ansible.cfg
若要包含现有插件的完整配置示例：
ansible-config init --disabled -t all > ansible.cfg
旧版本（如 2.9）
旧版配置文件示例可能不完整，建议参考对应版本的稳定分支代码库。例如 2.9 版本的示例文件：
https://github.com/ansible/ansible/blob/stable-2.9/examples/ansible.cfg
常用基础配置示例
以下是一个禁用 SSH 主机密钥检查的基础配置片段，通常用于测试环境：
ini
[defaults]
host_key_checking = False注意事项
- 生成的文件中所有选项默认被注释，需根据需求手动取消注释并修改。
- 生产环境中建议启用
host_key_checking以确保安全性。 - 插件相关配置（如
-t all生成的）需结合实际使用的插件进行调整。
cat /etc/ansible/ansible.cfg
Since Ansible 2.12 (core):
To generate an example config file (a "disabled" one with all default settings, commented out):
$ ansible-config init --disabled > ansible.cfg
Also you can now have a more complete file by including existing plugins:
ansible-config init --disabled -t all > ansible.cfg
For previous versions of Ansible you can check for examples in the 'stable' branches of each version
Note that this file was always incomplete and lagging changes to configuration settings
for example, for 2.9: https://github.com/ansible/ansible/blob/stable-2.9/examples/ansible.cfg
[defaults]
host_key_checking = Falsecat /etc/ansible/hosts
This is the default ansible 'hosts' file.
It should live in /etc/ansible/hosts
- Comments begin with the '#' character
- Blank lines are ignored
- Groups of hosts are delimited by [header] elements
- You can enter hostnames or ip addresses
- A hostname/ip can be a member of multiple groups
Ex 1: Ungrouped hosts, specify before any group headers:
green.example.com
blue.example.com
192.168.100.1
192.168.100.10
Ex 2: A collection of hosts belonging to the 'webservers' group:
[webservers]
alpha.example.org
beta.example.org
192.168.1.100
192.168.1.110
If you have multiple hosts following a pattern, you can specify
them like this:
www[001:006].example.com
You can also use ranges for multiple hosts:
db-[99:101]-node.example.com
Ex 3: A collection of database servers in the 'dbservers' group:
[dbservers]
db01.intranet.mydomain.net
db02.intranet.mydomain.net
10.25.1.56
10.25.1.57
Ex4: Multiple hosts arranged into groups such as 'Debian' and 'openSUSE':
[Debian]
alpha.example.org
beta.example.org
[openSUSE]
green.example.com
blue.example.com
