# config file for ansible -- http://ansible.com/
# ==============================================
# nearly all parameters can be overridden in ansible-playbook
# or with command line flags. ansible will read ANSIBLE_CONFIG,
# ansible.cfg in the current working directory, .ansible.cfg in
# the home directory or /etc/ansible/ansible.cfg, whichever it
# finds first
[defaults] --->通用默认配置
# some basic default values...
inventory = /etc/ansible/hosts 这个是默认库文件位置,脚本,或者存放可通信主机的目录
#library = /usr/share/my_modules/ Ansible默认搜寻模块的位置
remote_tmp = $HOME/.ansible/tmp Ansible 通过远程传输模块到远程主机,然后远程执行,执行后在清理现场.在有些场景下,你也许想使用默认路径希望像更换补丁一样使用
pattern = * 如果没有提供“hosts”节点,这是playbook要通信的默认主机组.默认值是对所有主机通信
forks = 5 在与主机通信时的默认并行进程数 ，默认是5d
poll_interval = 15 当具体的poll interval 没有定义时,多少时间回查一下这些任务的状态, 默认值是5秒
sudo_user = root sudo使用的默认用户 ，默认是root
#ask_sudo_pass = True 用来控制Ansible playbook 在执行sudo之前是否询问sudo密码.默认为no
#ask_pass = True 控制Ansible playbook 是否会自动默认弹出密码
transport = smart 通信机制.默认 值为’smart’。如果本地系统支持 ControlPersist技术的话,将会使用(基于OpenSSH)‘ssh’,如果不支持讲使用‘paramiko’.其他传输选项包括‘local’, ‘chroot’,’jail’等等
#remote_port = 22 远程SSH端口。 默认是22
module_lang = C 模块和系统之间通信的计算机语言，默认是C语言
# plays will gather facts by default, which contain information about
# the remote system.
#
# smart - gather by default, but don‘t regather if already gathered
# implicit - gather by default, turn off with gather_facts: False
# explicit - do not gather by default, must say gather_facts: True
gathering = implicit 控制默认facts收集（远程系统变量）. 默认值为’implicit’, 每一次play,facts都会被收集
# additional paths to search for roles in, colon separated
#roles_path = /etc/ansible/roles roles 路径指的是’roles/’下的额外目录,用于playbook搜索Ansible roles
# uncomment this to disable SSH key host checking
#host_key_checking = False 检查主机密钥
# change this for alternative sudo implementations
sudo_exe = sudo 如果在其他远程主机上使用另一种方式执sudu操作.可以使用该参数进行更换
# what flags to pass to sudo 传递sudo之外的参数
#sudo_flags = -H
# SSH timeout SSH超时时间
timeout = 10
# default user to use for playbooks if user is not specified
# (/usr/bin/ansible will use current user as default)
#remote_user = root 使用/usr/bin/ansible-playbook链接的默认用户名，如果不指定，会使用当前登录的用户名
# logging is off by default unless this path is defined
# if so defined, consider logrotate
#log_path = /var/log/ansible.log 日志文件存放路径
# default module name for /usr/bin/ansible
#module_name = command ansible命令执行默认的模块
# use this shell for commands executed under sudo
# you may need to change this to bin/bash in rare instances
# if sudo is constrained
#executable = /bin/sh 在sudo环境下产生一个shell交互接口. 用户只在/bin/bash的或者sudo限制的一些场景中需要修改
# if inventory variables overlap, does the higher precedence one win
# or are hash values merged together? The default is ‘replace‘ but
# this can also be set to ‘merge‘.
#hash_behaviour = replace 特定的优先级覆盖变量
# list any Jinja2 extensions to enable here:
#jinja2_extensions = jinja2.ext.do,jinja2.ext.i18n 允许开启Jinja2拓展模块
# if set, always use this private key file for authentication, same as
# if passing --private-key to ansible or ansible-playbook
#private_key_file = /path/to/file 私钥文件存储位置
# format of string {{ ansible_managed }} available within Jinja2
# templates indicates to users editing templates files will be replaced.
# replacing {file}, {host} and {uid} and strftime codes with proper values.
ansible_managed = Ansible managed: {file} modified on %Y-%m-%d %H:%M:%S by {uid} on {host} 这个设置可以告知用户,Ansible修改了一个文件,并且手动写入的内容可能已经被覆盖.
# by default, ansible-playbook will display "Skipping [host]" if it determines a task
# should not be run on a host. Set this to "False" if you don‘t want to see these "Skipping"
# messages. NOTE: the task header will still be shown regardless of whether or not the
# task is skipped.
#display_skipped_hosts = True 显示任何跳过任务的状态 ，默认是显示
# by default (as of 1.3), Ansible will raise errors when attempting to dereference
# Jinja2 variables that are not set in templates or action lines. Uncomment this line
# to revert the behavior to pre-1.3.
#error_on_undefined_vars = False 如果所引用的变量名称错误的话, 将会导致ansible在执行步骤上失败
# by default (as of 1.6), Ansible may display warnings based on the configuration of the
# system running ansible itself. This may include warnings about 3rd party packages or
# other conditions that should be resolved if possible.
# to disable these warnings, set the following value to False:
#system_warnings = True 允许禁用系统运行ansible相关的潜在问题警告
# by default (as of 1.4), Ansible may display deprecation warnings for language
# features that should no longer be used and will be removed in future versions.
# to disable these warnings, set the following value to False:
#deprecation_warnings = True 允许在ansible-playbook输出结果中禁用“不建议使用”警告
# (as of 1.8), Ansible can optionally warn when usage of the shell and
# command module appear to be simplified by using a default Ansible module
# instead. These warnings can be silenced by adjusting the following
# setting or adding warn=yes or warn=no to the end of the command line
# parameter string. This will for example suggest using the git module
# instead of shelling out to the git command.
# command_warnings = False 当shell和命令行模块被默认模块简化的时,Ansible 将默认发出警告

# deeply nested home directories) this can exceed the character limit on
# file socket names (108 characters for most platforms). In that case, you
# may wish to shorten the string below.

# Example:
# control_path = %(directory)s/%%h-%%r
#control_path = %(directory)s/ansible-ssh-%%h-%%p-%%r
# Enabling pipelining reduces the number of SSH operations required to
# execute a module on the remote server. This can result in a significant
