ansible常用模块

nsible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

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@node1 ~]# vi /etc/ansible/inventory 

[webservers]
node2
[root@node1 ~]# ansible all -m ping
node2 | SUCCESS => {
    "ansible_facts": {
        "discovered_interpreter_python": "/usr/libexec/platform-python"
    },
    "changed": false,
    "ping": "pong"
}
[ro

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@node1 ~]# ansible node2 -a 'ls /tmp'

//在受控主机的/tmp目录下新建一个文件test
[root@node1 ~]# ansible node2 -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.

//command模块不支持管道符，不支持重定向
[root@node1 ~]# ansible node2 -a "echo 'hello world' > /tmp/test"
node2 | CHANGED | rc=0 >>
hello world > /tmp/test
[root@node1 ~]# ansible node2 -a 'cat /tmp/test'
node2 | CHANGED | rc=0 >>

[root@node1 ~]# ansible node2 -a 'ps -ef|grep vsftpd'
node2 | 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

//支持重定向
[root@node1 ~]# ansible node2 -m raw -a 'echo "hello world" > /tmp/test'
node2 | CHANGED | rc=0 >>
Shared connection to node2 closed.

[root@node1 ~]# ansible node2 -a 'cat /tmp/test'
node2 | CHANGED | rc=0 >>
hello world

//支持管道符
[root@node1 ~]# ansible node2 -m raw -a 'cat /tmp/test|grep -Eo hello'
node2 | CHANGED | rc=0 >>
hello
Shared connection to node2 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。

[root@node1 ~]# mkdir scripts
[root@node1 ~]# cd scripts/
[root@node1 scripts]# vi ip.sh

#!/bin/bash
ip a > /tmp/ip.txt
[root@node1 scripts]# ansible node2 -m script -a '~/scripts/ip.sh'
node2 | CHANGED => {
    "changed": true,
    "rc": 0,
    "stderr": "Shared connection to node2 closed.
",
    "stderr_lines": [
        "Shared connection to node2 closed."
    ],
    "stdout": "",
    "stdout_lines": []
}
[root@node1 scripts]# ansible node2 -m shell -a 'cat /tmp/ip.txt'

[root@ansible ~]# ll /etc/ansible/scripts/
总用量 4
-rw-r--r--. 1 root root 61 9月   8 18:59 a.sh
[root@ansible ~]# ansible 172.16.103.129 -m script -a '/etc/ansible/scripts/a.sh &>/tmp/a'

        "Shared connection to 172.16.103.129 closed."
    ],
    "stdout": "",
    "stdout_lines": []
}


//查看受控机上的/tmp/a文件内容
[root@ansible ~]# ansible 172.16.103.129 -m shell -a 'cat /tmp/a'
172.16.103.129 | SUCCESS | rc=0 >>
root:x:0:0:root:/root:/bin/bash
....此处省略N行
jerry:x:1000:1000::/home/jerry:/bin/bash

//由此可见确是在受控机上执行了主控机上的脚本，且输出记录到了受控机上。因为此处 
//的jerry用户是在受控机上才有的用户

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。

//下载一个163的yum源文件并开启此源
[root@ansible ~]# cd /etc/yum.repos.d/
[root@ansible yum.repos.d]# curl -o CentOS7-Base-163.repo http://mirrors.163.com/.help/CentOS7-Base-163.repo
[root@localhost ~]# sed -i 's/$releasever/7/g' /etc/yum.repos.d/CentOS7-Base-163.repo
[root@localhost ~]# sed -i 's/^enabled=.*/enabled=1/g' /etc/yum.repos.d/CentOS7-Base-163.repo

//将设置好的163源传到受控主机
[root@ansible ~]# ansible 172.16.103.129 -m template -a 'src=/etc/yum.repos.d/CentOS7-Base-163.repo dest=/etc/yum.repos.d/163.repo'

    "state": "file",
    "uid": 0
}

//查看受控机上是否有163源
[root@localhost ~]# ls /etc/yum.repos.d/
163.repo

ansible常用模块之yum

yum模块用于在指定节点机器上通过yum管理软件，其支持的参数主要有两个

• 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 vsftpd
[root@localhost ~]#


//在ansible主机上使用yum模块在受控机上安装vsftpd
[root@ansible ~]# ansible 172.16.103.129 -m yum -a 'name=vsftpd state=present'
