获取模块信息

-
获取所有模块信息，100多个

  • ansible-doc -l

获取每个模块的具体信息

  • ansible-doc
    example：ansible-doc ping

    PING

    A trivial test module, this module always returns pong' on successful contact. It does not make sense in playbooks, but it is useful from/usr/bin/udp’

    EXAMPLES:
    Test ‘webservers’ status

    udp webservers -m ping

嵌套执行命令roles

- name: create jdk home
  file: path={{ remote_jdk_home }} state=directory mode=0755

- name: xxxxxxxxx
  include: ../../init/tasks/main.yml

defaults 中变量定义

1：加双引号；2：变量名和变量之间，有空格；
diamond_db_key: "{{ diamond_db_ip }}_{{ diamond_db_name }}_dbkey"
manager_user1: "{{ manager_user_name }}"

tags

相同的tasks在不同的环境下面执行，通过tag来进行表面，如下图：

  useage: 
    udp-playbook setup.yml -v -kK -i hosts.ini --tags "ta"

- name: 1
  authorized_key: user={{ ansible_ssh_user }}  key="{{ lookup('file', '~/.ssh/id_rsa.pub') }}"  state=present
  tags: ta

- name: 2
  group: name={{ remote_user }}
  tags: always

- name: 3
  file: path={{ remote_home }} owner={{ remote_user }} group={{ remote_user }} state=directory recurse=yes mode=0755
  tags: tb

常见错误

ansible 中 scp scp: ambiguous target 错误还是因为ssh 增加了 -t 参数, scp不支持 -t 参数

disable python warning

To control the discovery behavior:

  • for individual hosts and groups, use the ansible_python_interpreter inventory variable
  • globally, use the interpreter_python key in the [defaults] section of ansible.cfg
