Ansible_常用模块

阅读原文时间：2023年07月09日阅读：3

一、Ansible常用模块

1、ansible常用模块command、shell、raw的区别：

command模块不是调用的shell的指令，所以没有bash的环境变量
shell模块调用的/bin/sh指令执行
raw很多地方和shell类似，更多的地方建议使用shell和command模块
- 但是如果是使用老版本python，需要用到raw，又或者是客户端是路由器，因为没有安装python模块，那就需要使用raw模块了

二、Ansible常用模块使用详解

1、ping模块

1️⃣：ping模块用于检查指定节点机器是否连通，用法很简单，不涉及参数，主机如果在线，则回复pong

实例：

[root@localhost ~]# ansible all -m ping
192.168.121.81 | SUCCESS => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": false,
"ping": "pong"
}

2、user模块

①：user模块常用参数

create_home ：【 yes | no 】
说明：默认创建帐户或主目录不存在时将为用户创建主目录；除非选择 no
group
说明：设置用户主要组
groups
说明：设置用户附加组；当设置为空字符串时' '，该用户将从主要组之外的所有组中删除
home
说明：设置用户的家目录
name
说明：要创建，删除或修改的用户的名称
password
说明：将用户密码设置为此加密值；要在Linux系统上创建禁用的帐户，请将其设置为'!'或'*'
remove ：【 yes | no 】
说明：当 state=asbent 时，删除与用户关联的目录；相当于：userdel --remove
shell
说明：设置用户的登陆的shell；如果不希望登陆可以设置 /sbin/nologin
state ：【 present | absent 】
说明：设置未present声明创建该用户；设置absent声明删除该用户
system ：【 yes | no 】
说明：当 state=present 时，将其设置为 yes 会使该用户成为系统帐户
uid
说明：指明用户的UID

②：在受控机上添加一个系统用户，用户名为zhangsan，UID为888，设置登陆的shell为/sbin/nologin，无家目录

实例：

[root@localhost ~]# ansible 192.168.121.81 -m user -a 'name=zhangsan uid=888 system=yes shell=/sbin/nologin create_home=no state=present'
192.168.121.81 | CHANGED => {

"home": "/home/zhangsan",
"name": "zhangsan",
"shell": "/sbin/nologin",
"state": "present",
"system": true,
"uid": 888
}

//查看受控主机上是否存在zhangsan 用户
[root@localhost ~]# ansible 192.168.121.81 -m command -a 'id zhangsan'
192.168.121.81 | CHANGED | rc=0 >>

②：在受控机上添加一个系统组，其GID为800，组名为zhangsan

实例：

[root@localhost ~]# ansible 192.168.121.81 -m group -a 'name=zhangsan system=yes gid=800 state=present'
192.168.121.81 | CHANGED => {

②：shell模块可能使用的参数

chdir
说明：运行命令之前，先切换到该目录
removes
说明：文件名（如果文件名不存在）将不会删除指定的文件
stdin
说明：将命令的 stdin 直接设置为指定值

③：shell模块亦支持管道与重定向

7、raw模块

1️⃣：raw模块用于在远程主机上执行命令，其支持管道符与重定向（除此之外，可以使用raw模块在其他不能安装服务：（例如路由器）上安装服务）

实例：

//使用管道符
[root@localhost ~]# ansible 192.168.121.81 -m raw -a 'cat /etc/group |grep root'
192.168.121.81 | CHANGED | rc=0 >>
root❌0:

//使用重定向

anaconda-ks.cfg test.sh

//执行控制节点上的脚本文件
[root@localhost ~]# ansible 192.168.121.81 -m script -a '/root/test.sh > /root/dir.txt'
192.168.121.81 | CHANGED => {

13、selinux模块

1️⃣：selinux模块常用参数：

policy
说明：如果state不是disabled，则需要使用要使用的SELinux策略的名称（例如）targeted
state ：【 enforcing | premissive | disabled 】
说明：
disabled #关闭selinux
permissive #临时关闭selinux
enforcing #强制执行selinux

例子：

name: Enable SELinux
selinux:
policy: targeted
state: enforcing
name: Put SELinux in permissive mode, logging actions that would be blocked.
selinux:
policy: targeted
state: permissive
name: Disable SELinux
selinux:
state: disabled
实例：

//查看受管主机的selinux状态
[root@ansible ~]# ansible all -m shell -a 'getenforce'
192.168.121.81 | CHANGED | rc=0 >>
Enforcing

//设置selinux为disabled
[root@ansible ~]# ansible all -m selinux -a 'state=disabled'
[WARNING]: SELinux state temporarily changed from 'enforcing' to 'permissive'. State change will take effect next reboot.
192.168.121.81 | CHANGED => {
"ansible_facts": {
"discovered_interpreter_python": "/usr/libexec/platform-python"
},
"changed": true,
"configfile": "/etc/selinux/config",
"msg": "Config SELinux state changed from 'enforcing' to 'disabled'",
"policy": "targeted",
"reboot_required": true,
"state": "disabled"
}
//忽略警告

//查看selinux状态
[root@ansible ~]# ansible all -m shell -a 'getenforce'
192.168.121.81 | CHANGED | rc=0 >>
Permissive

14、seport模块

1️⃣：seport模块管理网络端口类型定义（在selinux添加/删除允许开放的端口）

2️⃣：seport常用模块：

ports
说明：端口或端口范围；例如：1000-2000 ；200-500,7777（逗号分隔）
proto ：【 tcp | udp 】
说明：指定端口的协议；例如：proto=tcp；proto=udp
reload ：【 yes | no 】
说明：提交后重新加载SELinux策略
setype
说明：指定端口的selinux类型；例如：http服务：setype=http_port_t
state ：【 present | absent 】
说明：指定端口的状态：
present #添加允许开放该端口
absent #删除/关闭该端口

实例：

//查看受控主机上是否开放777端口
[root@ansible ~]# ansible all -m shell -a 'semanage port -l | grep http'
192.168.121.81 | CHANGED | rc=0 >>
http_cache_port_t tcp 8080, 8118, 8123, 10001-10010
http_cache_port_t udp 3130
http_port_t tcp 80, 81, 443, 488, 8008, 8009, 8443, 9000
pegasus_http_port_t tcp 5988
pegasus_https_port_t tcp 5989
//semanage命令需要安装额外的安装包才能使用该命令，我这是提前安装好了的

//使用seport模块允许开放777端口
[root@ansible ~]# ansible all -m seport -a 'ports=777 proto=tcp setype=http_port_t state=present'
192.168.121.81 | CHANGED => {

15、mount模块

1️⃣：mount模块用来挂载目录，也可以用来挂载镜像文件

2️⃣：mount常用的参数：

src
说明：选择所要安装文件的路径；当状态设置为present或mounted，必须使用该参数
path
说明：挂载的路径；例如 path=/mnt/files
fstype
说明：挂载文件系统类型；当状态为present或mounted，必须使用该参数
state ：【 mounted | unmounted | remounted | present | absent 】
说明：
mounted：如果是mounted，将在fstab中主动安装设备并进行适当配置；如果没有安装点，则将创建安装点
如果是unmounted，则无需更改fstab即可卸载设备
remounted指定要在挂载本身上强制刷新时重新安装设备
present仅指定要在fstab中配置设备，并且不触发或不需要安装
absent指定将设备安装项从fstab中删除，还将卸载设备并删除安装点
opts
说明：以什么方式挂载；例如：ro,rw

实例：

//查看/dev/sr0是否已经挂载
[root@ansible ~]# ansible all -m shell -a 'df -h'

16、yum_repository模块

1️⃣：yum_repository模块是用来添加或删除YUM仓库的

2️⃣：yum_repository模块常用的参数：

name
说明：唯一的存储库ID。也就是配置文件中“[ ]”中括号中写的内容；名称必须唯一name参数是必须设置的；仅当状态设置为present或时，才需要此参数absent
description
说明：人类可读的字符串，描述存储库；也就是配置文件中name=描述的字符串；仅在state设置为present时才需要此参数
baseurl
说明：yum存储库“ repodata”目录所在目录的URL；它也可以是多个URL的列表；说白了就是给仓库的地址；如果需要的参数状态设置为present
enbaled ：【 yes | no 】
说明：yum是否使用此存储库
yes 代表启用
no 代表不启用
pgpcheck ：【 yes | no 】
说明：yum是否应该对软件包执行GPG签名检查；可选boolean值：
yes 如果设置启用签名检查：则需要写入gpgkey=URL
no 不启用签名检查
file
说明：不带 .repo 扩展名的文件名，用于保存存储库。默认为name的值。
如果设置里name参数，name改变的是文件中[ ] 中中括号中的值；而file改变的是文件名的名称
如果设置了name参数，但不给值，name就使用DEFAULT作为仓库的名称；file任然是改变文件名的名称
state ：【 present | absent 】
说明：repo 文件的状态（是否创建）

3️⃣：演示实例：

//查看playbook

[root@localhost ~]# cat playbook.yml

hosts: client
gather_facts: no
tasks:
- name: add repository
  yum_repository:
  name: dvd
  baseurl: https://download.fedoraproject.org/pub/epel/$releasever/$basearch/
  description: my first repo
  enabled: yes
  gpgcheck: no
  file: jjyy
//执行playbook后，查看
[root@localhost yum.repos.d]# ls
jjyy.repo
[root@localhost yum.repos.d]# cat jjyy.repo
[dvd]
baseurl = https://download.fedoraproject.org/pub/epel/$releasever/$basearch/
enabled = 1
gpgcheck = 0
name = my first repo
