ansible-doc -l 查看所有模块
ansible-doc -s module 查看某个模块的参数
ansible-doc module 查看该模块更详细的信息
Ansible Ad-hoc
格式：ansible 主机/组 -m 模块名 -a "模块参数" ansible参数
·主机和组（主机清单中的主机和组）
·模块名 （可以通过ansible-doc -l 查看目前安装的模块，默认不使用commmand模块【可在/etc/ansible/ansbile.cfg 中修改默认模块module_name = command】）
·模块参数 （可以通过ansible-doc 模块名查看具体的用法和后面参数）
·ansible参数
命令执行模块：
·command模块（-a 命令 可以直接执行，但是不支持命令中带有'<''>''|''&' ）
ansible node1 -m command -a 'chdir=/tmp ls -l'
[WARNING]: log file at /var/log/ansible.log is not writeable and we cannot create it, aborting

·shell模块（用法和command基本一致，但shell是通过/bin/sh进行执行，所以shell模块可以执行任何命令，类似于在本机执行）
选项：
·free_form ：要执行的linux指令
·chdir：在执行指令之前，先切换到该指定目录，默认目录是远程主机的家目录
·creates：一个文件名，当文件存在，则命令不执行
·removes：一个文件名，当文件不存在，则命令不执行
[hum@control ansible]$ ansible node1 -m shell -a 'chdir=/opt ls'
[WARNING]: log file at /var/log/ansible.log is not writeable and we cannot create it, aborting
node1 | CHANGED | rc=0 >>
hosts
test.txt
·raw模块（用法和shell基本一致，同样可以执行任意命令，类似本机执行，但是raw没有chdir，creates，removes参数）
·script模块（将管理端的shekk在被管理主机上执行【其原理是先将shell复制到远程主机，再在远程主机上执行】）
ansible 主机|组 -m 模块名 -a "模块参数"
