1、shell模块
功能说明：在远程节点上执行一个命令，且支持特殊符号< > | &等
[root@m01~]# ansible-doc -s shell
- name: Execute commands in nodes.
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: # (required) 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!
removes: # a filename, when it does not exist, this step will
*not* be run.
stdin: # Set the stdin of the command directly to the
specified value.
warn: # if command warnings are on in ansible.cfg, do not
warn about this
particular line if
实践：增加文本
[root@m01~]# ansible oldboy -m shell -a "echo oldboy >/tmp/tmp.txt"
