一、ansible常用模块使用详解

ansible常用模块有：

ping
yum
template
copy
user
group
service
raw
command
shell
script

ansible常用模块raw、command、shell的区别：

shell模块调用的/bin/sh指令执行
command模块不是调用的shell的指令，所以没有bash的环境变量
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

1.ansible常用模块之ping

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

2.ansible常用模块之command

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。

command模块有一个缺陷就是不能使用管道符和重定向功能。

//查看受控主机的/tmp目录内容
[root@ansible ~]# ansible 192.168.111.142 -a 'ls /tmp'
192.168.111.142 | CHANGED | rc=0 >>
ansible_command_payload_z973ukjx
systemd-private-ac56c8c9ec59454cbb39a024c91beb72-chronyd.service-S24EYh
vmware-root_897-3979643105

//在受控主机的/tmp目录下新建一个文件test
[root@ansible ~]# ansible 192.168.111.142 -a 'touch /tmp/test'
[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.
192.168.111.142 | CHANGED | rc=0 >>

//查看一下是否创建成功
[root@ansible ~]# ansible 192.168.111.142 -a 'ls /tmp'
192.168.111.142 | CHANGED | rc=0 >>

test
vmware-root_897-3979643105

//command模块不支持管道符，不支持重定向
[root@ansible ~]# ansible 192.168.111.142 -a "echo 'hello world' > /tmp/test"
192.168.111.142 | CHANGED | rc=0 >>
hello world > /tmp/test

[root@ansible ~]# ansible 192.168.111.142 -a 'cat /tmp/test'
192.168.111.142 | CHANGED | rc=0 >>

[root@ansible ~]# ansible 192.168.111.142 -a 'ps -ef | grep httpd'
192.168.111.142 | FAILED | rc=1 >>
error: garbage option

Usage:
 ps [options]

 Try 'ps --help <simple|list|output|threads|misc|all>'
  or 'ps --help <s|l|o|t|m|a>'
 for additional help text.

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

3.ansible常用模块之raw

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@ansible ~]# ansible 192.168.111.142 -m raw -a 'echo "hello world" > /tmp/test'
192.168.111.142 | CHANGED | rc=0 >>
Shared connection to 192.168.111.142 closed.

[root@ansible ~]# ansible 192.168.111.142 -a 'cat /tmp/test'
192.168.111.142 | CHANGED | rc=0 >>
hello world

//支持管道符
[root@ansible ~]# ansible 192.168.111.142 -m raw -a 'cat /tmp/test | grep -Eo hello'
192.168.111.142 | CHANGED | rc=0 >>
hello
Shared connection to 192.168.111.142 closed.

4.ansible常用模块之shell

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。
shell模块亦支持管道与重定向。

//查看受控机上的脚本
[root@localhost ~]# ll /scripts/
total 4
-rw-r--r-- 1 root root 43 Oct 23 19:00 test.sh

//使用shell模块在受控机上执行受控机上的脚本
[root@ansible ~]# ansible 192.168.111.142 -m shell -a '/bin/bash /scripts/test.sh &> /tmp/test'
192.168.111.142 | CHANGED | rc=0 >>

[root@ansible ~]# ansible 192.168.111.142 -m shell -a 'cat /tmp/test'
192.168.111.142 | CHANGED | rc=0 >>

5.ansible常用模块之script

script模块用于在受控机上执行主控机上的脚本

[root@ansible ~]# ll /scripts/
total 4
-rw-r--r-- 1 root root 48 Oct 23 19:06 a.sh

[root@ansible ~]# ansible 192.168.111.142 -m script -a '/scripts/a.sh &> /tmp/a'
192.168.111.142 | CHANGED => {
    "changed": true,
    "rc": 0,
    "stderr": "Shared connection to 192.168.111.142 closed.\r\n",
    "stderr_lines": [
        "Shared connection to 192.168.111.142 closed."
    ],
    "stdout": "",
    "stdout_lines": []
}

//查看受控机上的/tmp/a文件内容
[root@ansible ~]# ansible 192.168.111.142 -m shell -a 'cat /tmp/a'
192.168.111.142 | CHANGED | rc=0 >>
123

hello world

6.ansible常用模块之template

template模块用于生成一个模板，并可将其传输至远程主机上。

[root@ansible ~]# ansible 192.168.111.142 -m template -a 'src=/etc/yum.repos.d/CentOS-Base.repo dest=/etc/yum.repos.d/centos.repo'
192.168.111.142 | CHANGED => {

name：要管理的包名
state：要进行的操作

state常用的值：

latest：安装软件
installed：安装软件
present：安装软件
removed：卸载软件
absent：卸载软件

若想使用yum来管理软件，请确保受控机上的yum源无异常。

//在受控机上查询看vsftpd软件是否安装
[root@localhost ~]# rpm -qa|grep httpd
[root@localhost ~]# 

//在ansible主机上使用yum模块在受控机上安装httpd
[root@ansible ~]# ansible 192.168.111.142 -m yum -a 'name=httpd state=present'
192.168.111.142 | CHANGED => {

12.ansible常用模块之file

file 模块可以帮助我们完成一些对文件的基本操作。比如，创建文件或目录、删除文件或目录、修改文件权限等

force：需要在两种情况下强制创建软链接，一种是源文件不存在，但之后会建立的情况下；另一种是目标软
链接已存在，需要先取消之前的软链，然后创建新的软链，有两个选项：yes|no
group：定义文件/目录的属组
mode：定义文件/目录的权限
owner：定义文件/目录的属主
path：必选项，定义文件/目录的路径
recurse：递归的设置文件的属性，只对目录有效
src：要被链接的源文件的路径，只应用于state=link的情况
dest：被链接到的路径，只应用于state=link的情况
state：
=directory：如果目录不存在，创建目录
=file：即使文件不存在，也不会被创建
=link：创建软链接
=hard：创建硬链接
=touch：如果文件不存在，则会创建一个新的文件，如果文件或目录已存在，则更新其最后修改时间
=absent：删除目录、文件或者取消链接文件

//创建文件
[root@ansible ~]# ansible 192.168.111.142 -m file -a 'path=/tmp/abc state=touch owner=root group=root'
