ANSIBLE安装和各类模块应用功能
安装配置ANSIBLE
- 下载ANSIBLE
[root@ansible ~]#yum install ansible
- 确认安装
[root@ansible ~]#ansible --version ansible 2.9.1 config file = /etc/ansible/ansible.cfg configured module search path = [u'/root/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules'] ansible python module location = /usr/lib/python2.7/site-packages/ansible executable location = /usr/bin/ansible python version = 2.7.5 (default, Oct 30 2018, 23:45:53) [GCC 4.8.5 20150623 (Red Hat 4.8.5-36)]
- 修改主机清单文件(添加要管理的主机)
[root@ansible ~]#vim /etc/ansible/hosts [websrvs] 192.168.39.27 192.168.39.37 192.168.39.47 [appsrvs] 192.168.39.57 192.168.39.77 192.168.39.8
- ANSIBLE选项使用
# ansible-doc 查看各类模块帮助
[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

- 作key验证连接
- 使用sshpass实现key验证
[root@ansible ~]#yum install sshpass -y # 使用这个工具批量实现key验证 # 使用口令提交直接查看远程主机信息 [root@ansible ~]#sshpass -p 123456 ssh 192.168.39.27 cat /etc/redhat-release CentOS Linux release 7.6.1810 (Core) [root@ansible ~]#sshpass -p 123456 ssh 192.168.39.37 cat /etc/redhat-release CentOS Linux release 7.6.1810 (Core) [root@ansible ~]#sshpass -p 123456 ssh 192.168.39.47 cat /etc/redhat-release CentOS Linux release 7.6.1810 (Core) [root@ansible ~]#ll ~/.ssh/ # 查看一下有生成的key的公钥私钥吗？ total 4 -rw-r--r-- 1 root root 525 Dec 4 19:49 known_hosts [root@ansible ~]#ssh-keygen Generating public/private rsa key pair.

- 使用for循环来进行批量部署key验证
# 由于以前连过三台机子因此链接过的配置成功了 [root@ansible ~]#NET=192.168.39;for i in 7 27 37 47 57 77 8 ;do sshpass -p 123456 ssh-copy-id $NET.$i ;done /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub" /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub" /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys Number of key(s) added: 1 Now try logging into the machine, with: "ssh '192.168.39.27'" and check to make sure that only the key(s) you wanted were added. /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub" /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys Number of key(s) added: 1 Now try logging into the machine, with: "ssh '192.168.39.37'" and check to make sure that only the key(s) you wanted were added. /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub" /usr/bin/ssh-copy-id: INFO: attempting to log in with the new key(s), to filter out any that are already installed /usr/bin/ssh-copy-id: INFO: 1 key(s) remain to be installed -- if you are prompted now it is to install the new keys Number of key(s) added: 1 Now try logging into the machine, with: "ssh '192.168.39.47'" and check to make sure that only the key(s) you wanted were added. /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub" /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub" /usr/bin/ssh-copy-id: INFO: Source of key(s) to be installed: "/root/.ssh/id_rsa.pub"
- 修改配置文件来进行key验证
# 在第一次远程链接的时候都会有一个提示就是输入yes/no（这个选项会影响第一次链接的服务器配置key因此在配置文件里修改一个选项来绕过这步） [root@ansible ~]#vim /etc/ssh/ssh_config # Host * # ForwardAgent no # ForwardX11 no # RhostsRSAAuthentication no # RSAAuthentication yes # PasswordAuthentication yes # HostbasedAuthentication no # GSSAPIAuthentication no # GSSAPIDelegateCredentials no # GSSAPIKeyExchange no # GSSAPITrustDNS no # BatchMode no # CheckHostIP yes # AddressFamily any # ConnectTimeout 0 StrictHostKeyChecking no # 这一项原本是注释掉的，去掉注释在后面改成no就能够了 # IdentityFile ~/.ssh/identity # IdentityFile ~/.ssh/id_rsa # IdentityFile ~/.ssh/id_dsa # IdentityFile ~/.ssh/id_ecdsa # IdentityFile ~/.ssh/id_ed25519 # Port 22
- 再次进行配置(以前配置好的不会在配置)
[root@ansible ~]#NET=192.168.39;for i in 7 27 37 47 57 77 8 ;do sshpass -p 123456 ssh-copy-id $NET.$i ;done

ansible经常使用模块
Command 模块
功能：在远程主机执行命令，此为默认模块，可忽略-m选项 注意：此命令不支持 $VARNAME < > | ; & 等，用shell模块实现

shell模块
- shell模块简单说明
[root@ansible ~]#ansible-doc -s shell
- name: Execute shell commands on targets
shell:
chdir: # Change into this directory before running the command.
cmd: # The command to run followed by optional arguments.
creates: # A filename, when it already exists, this step will
*not* be run.
executable: # Change the shell used to execute the command. This
expects an absolute
path to the executable.
free_form: # The shell module takes a free form command to run, as
a string. There is no
actual parameter named
'free form'. See the
examples on how to use
this module.
removes: # A filename, when it does not exist, this step will
*not* be run.
stdin: # Set the stdin of the command directly to the specified
value.
stdin_add_newline: # Whether to append a newline to stdin data.
warn: # Whether to enable task warnings.

script模块
功能：：在远程主机上运行ansible服务器上的脚本
- 模块简单介绍
[root@ansible ~]#ansible-doc -s script
- name: Runs a local script on a remote node after transferring it
script:
chdir: # Change into this directory on the remote node before
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.
removes: # A filename on the remote node, when it does not exist,
this step will *not* be
run.
- 在ansible主机写一个脚原本测试
[root@ansible ~]#cat test.sh #!/bin/bash touch /data/host.txt # 测试使用没写多
- 开始使用script模块执行脚本在远程实现

copy模块
功能：从ansible服务器主控端复制文件到远程主机
- 模块简单介绍
[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模块
功能：解包解压缩
实现有两种用法：
一、将ansible主机上的压缩包传到远程主机后解压缩至特定目录，设置copy=yes
二、将远程主机上的某个压缩包解压缩到指定路径下，设置copy=no
- 常见参数：
- copy：默认为yes，当copy=yes，拷贝的文件是从ansible主机复制到远程主机上，若是设置为copy=no，会在远程主机上寻找src源文件
- remote_src：和copy功能同样且互斥，yes表示在远程主机，不在ansible主机，no表示文件在ansible主机上
- src：源路径，能够是ansible主机上的路径，也能够是远程主机上的路径，若是是远程主机上的路径，则须要设置copy=no
- dest：远程主机上的目标路径
- mode：设置解压缩后的文件权限
- 先打包一个文件夹

- name: Manage hostname
hostname:
name: # (required) Name of the host
use: # Which strategy to use to update the hostname. If not set we
try to autodetect, but this
can be problematic, specially
with containers as they can
present misleading
information.
- 直接使用的话全部的主机名都会改为同样的了

Cron模块
功能：计划任务,支持时间：minute，hour，day，month，weekday
- 模块简介
[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模块
功能：管理组
- 模块简介
[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模块
功能：获得远程主机的信息
- 模块简介
[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',
