使用shell模块，在远程命令通过/bin/sh来执行；所以，我们在终端输入的各种命令方式，都可以使用；
但是我们自己定义在.bashrc/.bash_profile中的环境变量shell模块由于没有加载，所以无法识别；如果需要使用自定义的环境变量，就需要在最开始，执行加载自定义脚本的语句；
对shell模块的使用可以分成两块：
shell模块用法和command参数一样
[root@ansible ~]# ansible-doc -s shellless 436

- name: Execute commands in nodes.
action: shell
chdir # cd into this directory before running the command
creates # a filename, when it already exists, this step will *not* be run.
executable # change the shell used to execute the command. Should be an absolute path to the executable.
free_form= # The shell module takes a free form command to run, as a string. There's not an actual option
named "free form". See the examples!

warn # if command warnings are on in ansible.cfg, do not warn about this particular line if set to
no/false.
如果待执行的语句少，写在一起也可以，还可以加载环境......[root@ansible ~]# ansible web -m shell -a '. ~/.bash_profile;ps -ef|grep httpd'web | SUCCESS | rc=0 >>root 4406 4405 0 06:32 pts/0 00:00:00 /bin/sh -c . ~/.bash_profile;ps -ef|grep httpdroot 4410 4406 0 06:32 pts/0 00:00:00 grep httpd
scripts模块可以在本地写一个脚本，然后在远程服务器上执行。如下
script用法
[root@ansible ~]# ansible-doc -s scriptless 436Copyright (C) 1984-2009 Mark Nudelmanless comes with NO WARRANTY, to the extent permitted by law.For information about the terms of redistribution,see the file named README in the less distribution.Homepage: http://www.greenwoodsoftware.com/less- name: Runs a local script on a remote node after transferring it action: script creates # a filename, when it already exists, this step will *not* be run. free_form= # path to the local script file followed by optional arguments. removes # a filename, when it does not exist, this step will *not* be run.
name: 将本地脚本复制到远程主机并运行之
action: script
creates # 一个文件名，当这个文件存在，则该命令不执行
free_form= # 本地脚本路径
removes # 一个文件名，这个文件不存在，则该命令不执行
[root@ansible ~]# cat time.sh #!/bin/bashdate > /tmp/shijian
使用script模块执行，使用是相当路径也可以使用绝对路径。
[root@ansible ~]# ansible web -m script -a 'time.sh'web | SUCCESS => { "changed": true, "rc": 0, "stderr": "", "stdout": "", "stdout_lines": []}
验证下web服务器上内容
[root@ansible ~]# ansible web -a 'cat /tmp/shijian'
web | SUCCESS | rc=0 >>
