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 # set plugin path directories here, separate with colons action_plugins = /usr/share/ansible_plugins/action_plugins callback_plugins = /usr/share/ansible_plugins/callback_plugins connection_plugins = /usr/share/ansible_plugins/connection_plugins lookup_plugins = /usr/share/ansible_plugins/lookup_plugins vars_plugins = /usr/share/ansible_plugins/vars_plugins filter_plugins = /usr/share/ansible_plugins/filter_plugins # by default callbacks are not loaded for /bin/ansible, enable this if you # want, for example, a notification or logging callback to also apply to # /bin/ansible runs #bin_ansible_callbacks = False 用来控制callback插件是否在运行 /usr/bin/ansible 的时候被加载. 这个模块将用于命令行的日志系统,发出通知等特性 # don't like cows? that's unfortunate. # set to 1 if you don't want cowsay support or export ANSIBLE_NOCOWS=1 #nocows = 1 默认ansible可以调用一些cowsay的特性 开启/禁用:0/1# don't like colors either?# set to 1 if you don't want colors, or export ANSIBLE_NOCOLOR=1#nocolor = 1 输出带上颜色区别, 开启/关闭:0/1# the CA certificate path used for validating SSL certs.
