Ansible常用模块

1Ansible常用模块详解

1.1模块介绍

• 模块是临时命令用于完成任务的工具。Ansible提供了数百个能够完成不同任务的模块。通常我们可以查找一个经过测试的专用模块，作为标准安装的一部分来完成所需的任务
• ansible-doc -l命令可以列出系统上安装的所有模块。可以使用ansible-doc来按照名称查看特定模块的帮助文档，再查找关于模块将取什么参数作为选项的信息
• 大部分模块会取用参数。可在模块的文档中找到可用于该模块的参数列表。可以通过-a选项向模块传递参数。无需参数时，可从省略-a选项。如果需要指定多个参数，请以引号括起的空格分隔列表形式提供

1.2模块分类

模块类型	模块
文件模块	copy：将本地文件复制到受管主机 file：设置文件的权限和其他属性lineinfile：确保特定行是否在文件中 synchronize：使用rsync同步内容
软件包模块	package：使用操作系统本机的自动检测软件包管理器管理软件包 yum：使用yum管理软件包 apt：使用APT管理软件包 dnf：使用dnf管理软件包 gem：管理Ruby gempip：从PyPI管理Python软件包
系统模块	firewalld：使用firewalld管理防火墙 reboot：重启计算机 service：管理服务 user：添加、删除和管理用户帐户
Net Tools模块	get_url：通过HTTP、HTTPS或FTP下载文件 nmcli：管理网络 uri：与Web服务交互

其他模块

• 云模块
• 命令模块
• 数据库模块
• 资产模块
• 消息模块
• 监控模块
• 网络模块
• 通知模块
• 源码控制模块
• 单元模块
• web设施模块
• windows模块

1.3Ansible常用模块

• ping
• yum
• template
• copy
• user
• group
• service
• raw
• command
• shell
• script

1.4ansible常用模块raw、command、shell的区别

command，shell模块：

• 要求受管主机上安装python，command可以在受管主机上执行shell命令，但不支持环境变量和操作符(例如 ’ | ’ .’<’ ,’>’ ,’&’)
• shell模块调用的/bin/sh指令执行

raw模块：

• 不需要受管主机上安装python，直接使用远程shell运行命令
• 通常用于无法安装python的系统(例如网络设备)

2Ansible常用模块

2.1ping模块

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

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

2.2command模块

command模块用于在远程主机上执行命令，ansible默认就是使用command模块。(即不指定模块默认使用command模块)

[root@localhost ansible]# ansible all -m command -a 'ls /opt'
192.168.25.130 | CHANGED | rc=0 >>
abc

[root@localhost ansible]# ansible all -a 'ls /opt'
192.168.25.130 | CHANGED | rc=0 >>
abc

command模块参数

• chdir 指定一个目录，在执行命令前，会先进入到chdir指定的目录

[root@localhost ansible]# ansible all -m command -a "chdir=/opt/ ls"
192.168.25.130 | CHANGED | rc=0 >>
abc

• creates creates并不会帮助我们创建文件，他的作用是当指定文件存在时，就不会执行命令，例如/opt/abc文件存在时，就不执行指定的命令

[root@node1 ~]# cd /opt/
[root@node1 opt]# ls
abc
[root@localhost ansible]# ansible all -m command -a "creates=/opt/abc echo redhat-test"
192.168.25.130 | SUCCESS | rc=0 >>
skipped, since /opt/abc exists

• 不存在/opt/abc时，执行redhat-test命令

[root@node1 ~]# cd /opt/
[root@node1 opt]# ls
[root@node1 opt]# 

[root@localhost ansible]# ansible all -m command -a "creates=/opt/abc echo redhat-test"
192.168.25.130 | CHANGED | rc=0 >>
redhat-test

• removes 当指定的文件不存在时，就不执行就不执行命令

[root@node1 ~]# cd /opt/
[root@node1 opt]# ls
[root@node1 opt]# 
[root@localhost ansible]# ansible all -m command -a "removes=/opt/abc echo redhat-test"
192.168.25.130 | SUCCESS | rc=0 >>
skipped, since /opt/abc does not exist

• 当/opt/abc存在时，执行redha-test命令

[root@node1 ~]# cd /opt/
[root@node1 opt]# ls
abc
[root@localhost ansible]# ansible all -m command -a "removes=/opt/abc echo redhat-test"
192.168.25.130 | CHANGED | rc=0 >>
redhat-test

• touch 创建文件

[root@localhost ansible]# ansible all -m command -a 'touch /opt/ll'
[WARNING]: Consider using the file module with state=touch rather than running
'touch'.  If you need to use command because file 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.
192.168.25.130 | CHANGED | rc=0 >>

[root@localhost ansible]# ansible all -m command -a 'chdir=/opt/ ls'
192.168.25.130 | CHANGED | rc=0 >>
abc
ll

command模块有一个缺陷就是不能使用管道符和重定向功能

[root@localhost ansible]# ansible all -m command -a "echo 'hello world' > /opt/ll"
192.168.25.130 | CHANGED | rc=0 >>
hello world > /opt/ll
[root@localhost ansible]# ansible all -m command -a 'cat /opt/ll'
192.168.25.130 | CHANGED | rc=0 >>
[root@localhost ansible]# ansible all -m command -a 'ps -ef|grep vsftpd'
192.168.25.130 | FAILED | rc=1 >>
error: unsupported SysV option

Usage:
 ps [options]

 Try 'ps --help '
  or 'ps --help '
 for additional help text.

For more details see ps(1).non-zero return code

2.3raw模块

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

//支持重定向
[root@localhost ansible]# ansible all -m raw -a 'echo "hell word" > /opt/ll'
192.168.25.130 | CHANGED | rc=0 >>

2.4shell模块

• shell模块用于在受控机上执行受控机上的脚本，亦可直接在受控机上执行命令且shell模块亦支持管道与重定向
• shell模块在远程主机中执行命令时会经过远程主机上的/bin/sh程序处理

//脚本文件
[root@node1 ~]# vim test.sh
[root@node1 ~]# cat test.sh 
#!/bin/bash

echo "hello word"
[root@node1 ~]# chmod +x test.sh 
[root@node1 ~]# ll

#!/bin/bash

echo "hello word"

//使用shell模块在受控机上执行受控机上的脚本
[root@localhost ansible]# ansible all -m shell -a '/bin/bash /root/test.sh &> /opt/test.log'
192.168.25.130 | CHANGED | rc=0 >>
[root@localhost ansible]# ansible all -m command -a 'cat /opt/test.log'
192.168.25.130 | CHANGED | rc=0 >>

2.5script模块

script模块是在受控主机上执行ansible管理主机上的脚本，脚本存在于ansible管理主机上，不需要拷贝到受控主机后在执行（即script模块用于在受控机上执行主控机上的脚本）

//脚本文件
[root@localhost ansible]# ls
ansible.cfg  hosts  inventory  roles
[root@localhost ansible]# mkdir scripts
[root@localhost ansible]# cd scripts/
[root@localhost scripts]# vim test.sh
[root@localhost scripts]# cat test.sh
#！/bin/bash

useradd tom
echo "redhat" | passwd --stdin tom
echo "hello word" > ~tom/abc

//在主控机上执行脚本文件
[root@localhost ansible]# ansible all -m script -a 'scripts/test.sh'
192.168.25.130 | CHANGED => {
    "changed": true,
    "rc": 0,

    ]
}

//查看受控机上的内容
[root@node1 ~]# id tom
uid=1001(tom) gid=1002(tom) 组=1002(tom)
[root@node1 ~]# cd /home/tom/
[root@node1 tom]# ls
abc
[root@node1 tom]# cat abc 
hello word

2.6template模块

• template模块可以将带有参数的配置文件传递到目标地址并且可以对文件进行参数的修改以及备份
• template模块用于生成一个模板，并可将其传输至远程主机上

//传输文件

2.12lineinfile模块

• lineinfile模块用于确保一个特定的行在一个文件中，或者确保从文件中删除指定的文本(即确保指定的文本不存在于文件中)，还可以使用一个正则表达式替换“某一行的文本”

常用参数

• path 指定要操作的文件
• line 指定文本内容
• state 设置状态【当想要删除对应文本时，需要将state参数设置为absent。state默认值为present】
• regexp 使用正则表达式匹配对应的行【当替换文本时，如多行被匹配则只有最后面被匹配的那行文本会被替换，当删除文本时，有多行被匹配，那么哲学行都会被删除】
• insertafter 借助insertafter可以将文本插入到“指定的行”之后

//将/etc/selinx/config中的SELINUX=enforcing跟改为disabled

#     disabled - No SELinux policy is loaded.
SELINUX=disabled
# SELINUXTYPE= can take one of these three values:
#     targeted - Targeted processes are protected,
#     minimum - Modification of targeted policy. Only selected processes are protected.
