Ansible常用模块详解

ansible常用模块有：

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

ansible常用模块raw、command、shell的区别：

  1. shell模块调用的/bin/sh指令执行
  2. command模块不是调用的shell的指令，所以没有bash的环境变量
  3. 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

ansible常用模块之ping

//将受控主机加入ansible清单
[root@ansible ~]# cd /etc/ansible/
[root@ansible ansible]# ls
ansible.cfg  hosts  roles
[root@ansible ansible]# touch inventory
[root@ansible ansible]# ls
ansible.cfg  hosts  inventory  roles
[root@ansible ansible]# vim ansible.cfg 
#inventory      = /etc/ansible/hosts    //取消注释并修改为下面这样
inventory       = /etc/ansible/inventory
[root@ansible ansible]# vim inventory 
[root@ansible ansible]# cat inventory 
[web]
192.168.222.137
[root@ansible ansible]# ansible all -m ping
192.168.222.137 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false,
    "ping": "pong"
}

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]# ansible 192.168.222.137 -a 'ls /tmp'
192.168.222.137 | CHANGED | rc=0 >>

vmware-root_901-3988228452
vmware-root_903-3979774182
//在受控主机的/tmp目录下新建一个文件test
[root@ansible ansible]# ansible 192.168.222.137 -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.

192.168.222.137 | CHANGED | rc=0 >>

[root@ansible ansible]# ansible 192.168.222.137 -a 'cat /tmp/test'

[root@ansible ansible]# ansible 192.168.222.137 -a 'ps -ef|grep vsftpd'
192.168.222.137 | FAILED | rc=1 >>
error: unsupported SysV 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

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

[root@ansible ansible]# ansible 192.168.222.137 -m raw -a 'echo "hello world" > /tmp/test'
192.168.222.137 | CHANGED | rc=0 >>

[root@ansible ansible]# ansible 192.168.222.137 -a 'cat /tmp/test'
192.168.222.137 | CHANGED | rc=0 >>
hello world
[root@ansible ansible]# ansible 192.168.222.137 -m raw -a 'cat /tmp/test|grep -Eo hello'
192.168.222.137 | CHANGED | rc=0 >>
hello
Shared connection to 192.168.222.137 closed.

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@nginx ~]# mkdir /scripts/

[root@nginx scripts]# vim test.sh
[root@nginx scripts]# cat test.sh 
#!/bin/bash

for i in ${my_arry[@]};do
    echo $i
done
[root@nginx scripts]# chmod +x test.sh 
[root@nginx scripts]# cd
[root@nginx ~]# ll /scripts/

//使用shell模块在主控机上执行受控机上的脚本
[root@ansible ansible]# ansible 192.168.222.137 -m shell -a '/bin/bash /scripts/test.sh &> /tmp/test'
192.168.222.137 | CHANGED | rc=0 >>
