# ansible-doc 查看各種模塊幫助
[root@ansible ~]#ansible-doc ping
> PING (/usr/lib/python2.7/site-packages/ansible/modules/system/ping.py)
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/ansible' to verify the ability to
login and that a usable Python is configured. This is NOT ICMP
ping, this is just a trivial test module that requires Python
on the remote-node. For Windows targets, use the [win_ping]
module instead. For Network targets, use the [net_ping] module
instead.
* This module is maintained by The Ansible Core Team
OPTIONS (= is mandatory):
- data
Data to return for the `ping' return value.
If this parameter is set to `crash', the module will cause an
exception.
[Default: pong]
type: str

- 做key驗證鏈接
- 使用sshpass實作key驗證
[root@ansible ~]#yum install sshpass -y # 使用這個工具批量實作key驗證

ansible-galaxy工具
此工具會連接 https://galaxy.ansible.com 下載相應的roles
范例：
[root@ansible ~]#ansible-galaxy install geerlingguy.redis
- downloading role 'redis', owned by geerlingguy
- downloading role from https://github.com/geerlingguy/ansible-role-redis/archive/1.6.0.tar.gz
- extracting geerlingguy.redis to /root/.ansible/roles/geerlingguy.redis
- geerlingguy.redis (1.6.0) was installed successfully
[root@ansible ~]#ansible-galaxy list
# /root/.ansible/roles
- geerlingguy.redis, 1.6.0
# /usr/share/ansible/roles
# /etc/ansible/roles
[root@ansible ~]#ansible-galaxy remove geerlingguy.redis
- successfully removed geerlingguy.redis
[root@ansible ~]#ansible-galaxy list
# /root/.ansible/roles
# /usr/share/ansible/roles
# /etc/ansible/roles
#列出所有已安裝的galaxy
ansible-galaxy list
#安裝galaxy
ansible-galaxy install geerlingguy.redis
#洗掉galaxy
ansible-galaxy remove geerlingguy.redis
ansible-pull工具
此工具會推送ansible的命令至遠程，效率無限提升，對運維要求較高
ansible-playbook
此工具用于執行撰寫好的playbook任務
范例：
[root@ansible ~]#ansible-playbook hello.yml
[root@ansible ~]#cat hello.yml
---
#hello world yml file
- hosts: websrvs
remote_user: root
tasks:
- name: hello world
command: /usr/bin/wall hello world
ansible常用模塊
Command 模塊
功能：在遠程主機執行命令，此為默認模塊，可忽略-m選項
注意：此命令不支持 $VARNAME < > | ; & 等，用shell模塊實作

[WARNING]: Consider using the replace, lineinfile or template module rather than
running 'sed'. If you need to use command because replace, lineinfile or template is
insufficient you can add 'warn: false' to this command task or set
'command_warnings=False' in ansible.cfg to get rid of this message. # 這些提示是修改這個檔案這個模塊不是專業的，有更專業的模塊，（一般顯示為粉色）

running the script.
cmd: # Path to the local script to run followed by optional
arguments.
creates: # A filename on the remote node, when it already exists,
this step will *not* be
run.
decrypt: # This option controls the autodecryption of source
files using vault.
executable: # Name or path of a executable to invoke the script
with.
free_form: # Path to the local script file followed by optional
arguments.

this step will *not* be

copy模塊
功能：從ansible服務器主控端復制檔案到遠程主機
- 模塊簡單介紹
[root@ansible ~]#ansible-doc -s copy
- name: Copy files to remote locations
copy:
attributes: # The attributes the resulting file or directory should have.
To get supported flags look at
the man page for `chattr' on
the target system. This string
should contain the attributes
in the same order as the one
displayed by `lsattr'. The `='
operator is assumed as
default, otherwise `+' or `-'
operators need to be included
in the string.
backup: # Create a backup file including the timestamp information so
you can get the original file
back if you somehow clobbered
it incorrectly.
checksum: # SHA1 checksum of the file being transferred. Used to validate
that the copy of the file was
successful. If this is not
provided, ansible will use the
local calculated checksum of
the src file.
content: # When used instead of `src', sets the contents of a file
directly to the specified
value. Works only when `dest'
is a file. Creates the file if
it does not exist. For
advanced formatting or if
`content' contains a variable,
use the [template] module.
decrypt: # This option controls the autodecryption of source files using
vault.
dest: # (required) Remote absolute path where the file should be
copied to. If `src' is a
directory, this must be a
directory too. If `dest' is a
non-existent path and if
either `dest' ends with "/" or
`src' is a directory, `dest'
is created. If `dest' is a

unarchive模塊
功能：解包解壓縮
實作有兩種用法：
1、將ansible主機上的壓縮包傳到遠程主機后解壓縮至特定目錄，設定copy=yes
2、將遠程主機上的某個壓縮包解壓縮到指定路徑下，設定copy=no
- 常見引數：
- copy：默認為yes，當copy=yes，拷貝的檔案是從ansible主機復制到遠程主機上，如果設定為copy=no，會在遠程主機上尋找src源檔案
- remote_src：和copy功能一樣且互斥，yes表示在遠程主機，不在ansible主機，no表示檔案在ansible主機上
- src：源路徑，可以是ansible主機上的路徑，也可以是遠程主機上的路徑，如果是遠程主機上的路徑，則需要設定copy=no
- dest：遠程主機上的目標路徑
- mode：設定解壓縮后的檔案權限
- 先打包一個檔案夾

hostname:
name: # (required) Name of the host

try to autodetect, but this
can be problematic, specially
with containers as they can
present misleading
information.

Cron模塊
功能：計劃任務,支持時間：minute，hour，day，month，weekday
- 模塊簡介
[root@ansible ~]#ansible-doc -s cron
- name: Manage cron.d and crontab entries
cron:
backup: # If set, create a backup of the crontab before it is modified.
The location of the backup is
returned in the `backup_file'
variable by this module.
cron_file: # If specified, uses this file instead of an individual user's
crontab. If this is a relative
path, it is interpreted with
respect to `/etc/cron.d'. If
it is absolute, it will
typically be `/etc/crontab'.
Many linux distros expect (and
some require) the filename
portion to consist solely of
upper- and lower-case letters,
digits, underscores, and
hyphens. To use the
`cron_file' parameter you must
specify the `user' as well.
day: # Day of the month the job should run ( 1-31, *, */2, etc )
disabled: # If the job should be disabled (commented out) in the crontab.
Only has effect if
`state=present'.
env: # If set, manages a crontab's environment variable. New
variables are added on top of
crontab. `name' and `value'
parameters are the name and
the value of environment
variable.
hour: # Hour when the job should run ( 0-23, *, */2, etc )
insertafter: # Used with `state=present' and `env'. If specified, the
environment variable will be
inserted after the declaration
of specified environment
variable.
insertbefore: # Used with `state=present' and `env'. If specified, the
environment variable will be
inserted before the
declaration of specified
environment variable.

Group模塊
功能：管理組
- 模塊簡介
[root@ansible ~]#ansible-doc -s group
- name: Add or remove groups
group:
gid: # Optional `GID' to set for the group.
local: # Forces the use of "local" command alternatives
on platforms that
implement it.
This is useful in
environments that
use centralized
authentication
when you want to
manipulate the
local groups.
(e.g. it uses
`lgroupadd'
instead of
`groupadd'). This
requires that
these commands
exist on the
targeted host,
otherwise it will
be a fatal error.
name: # (required) Name of the group to manage.
non_unique: # This option allows to change the group ID to a
non-unique value.
Requires `gid'.
Not supported on
macOS or BusyBox
distributions.
state: # Whether the group should be present or not on
the remote host.
system: # If `yes', indicates that the group created is
system group.

setup模塊
功能：得到遠程主機的資訊
- 模塊簡介
[root@ansible ~]#ansible-doc -s setup
- name: Gathers facts about remote hosts
setup:
fact_path: # Path used for local ansible facts (`*.fact') -
files in this dir
will be run (if
executable) and
their results be
added to
`ansible_local'
facts if a file
is not executable
it is read. Check
notes for Windows
options. (from
2.1 on)
File/results
format can be
JSON or INI-
format. The
default
`fact_path' can
be specified in
`ansible.cfg' for
when setup is
automatically
called as part of
`gather_facts'.
filter: # If supplied, only return facts that match this
shell-style
(fnmatch)
wildcard.
gather_subset: # If supplied, restrict the additional facts
collected to the
given subset.
Possible values:
`all', `min',
`hardware',
`network',
`virtual',
