官方配置文件文档

　　Ansible安装完成之后默认配置文件为：/etc/asnible/ansible.cfg

　　Ansible配置文件内容：

• inventory：这个参数表示资源清单inventory文件配置，资源清单是就一些Ansible需要连接管理的主机列表。安装完成Ansible之后默认的配置如下：inventory = /etc/ansible/hosts
• library：Ansible的操作动作，无论是本地或远程，都使用一小段代码来执行。这小段代码称为模块，这个library参数就是指向存放在Ansible模块的目录。Ansible支持多个目录方式，只要用冒号（:）隔开就可以，同时也会检查当前执行playbook位置下./library位置。默认配置如下：library = /usr/share/my_modules/
• forks：设置默认情况下Ansible最多能有多少个进程同时工作，默认设置5个线程并行处理。具体设置多少个线程并发处理可以根据实际业务需求来设置。
• sudo_user：设置默认执行命令的远端用户。默认配置如下：sudo_user = root
• remote_port：指定连接被管理远程主机的ssh端口，默认22。除非设置了特殊的ssh端口，不然这个参数是不需要更改的。默认配置如下：remote_port = 22
• host_key_checking：设置是否检查SSH主机密钥。可以设置为True或者False。，默认配置如下：host_key_checking = False
• timeout：设置SSH连接超时时间，单位是秒。默认配置如下：timeout = 10
• log_path：Ansible系统默认是不记录日志的，如果想要记录日志只需要配置好log_path对应日志文件的绝对路径即可。默认配置如下：#log_path = /var/log/ansible.log,只需要将前面的“#”号去掉即可开启日志记录。
• poll_interval：异步执行任务的时候多久检查一次任务装填，默认配置如下：poll_interval = 15
• transport：远程工具连接方式设置，默认是使用smart模式（智能模式），在你需要优化执行速度的时候可以修改这个参数，默认配置如下：transport = smart
• module_set_locale：设置本地环境变量，默认配置：module_set_locale = False
