Ansible batch automation management tool-copy module topic (two)

Warm up:

Concepts that need to be noted in advance when using ansible and its copy module:

A) 需要明确ansible管理管端，执行的用户
   root:   拥有所有权限
   普通用户：只拥有本身的权限

B）使用copy模块，涉及到copy master数据到remote,必须保证
   ansible执行者，对这些ansible机器中数据文件，具有w
  （可copy）权限

C）客户端（ansible被控端），必须确认client用户,对远程机器
  具有对应权限
  <client用户怎么确定？？？>
  1）/etc/ansible/hosts中ansible_ssh_user设置
  2）名字行执行：ansible web -m shell -a "xx" -u client用户

The ansible copy module uses:

Copy module parameter description:

parameter	Description
src	The local object file or folder copied to the remote host can be an absolute path or a relative path
dest	Local object files or folders copied to the remote host
mode	Set permissions for copy objects
owner	Setting owner of copy object
group	Copy target settings belong to group
backup	When the file exists, you can choose to back up the source file before overwriting. Setting value: yes/no The default is yes
force	Whether to force coverage. Setting value: yes/no default is no

Copy the file to the remote machine and set the "owner/group/permission"

ansible all -i hosts -m copy -a "src=./list dest=/root/ owner=china group=mockuser mode=0777"

Copy the file to the remote machine and back it up:

ansible all -i hosts  -m copy -a "src=./list。file dest=/tmp backup=yes"
【参数说明】
 hosts：类似/etc/ansible/hosts
 backup=yes表示：远程机器如果存在旧的list.file那么先备份原来的

Create a file for the remote machine and write data:

# 在目录下创建文件并写入内容dest 参数对应的值必须是一个文件，而不能是一个路径。

ansible -i hosts all -m copy -a 'content="aaa\nbbb\n" dest=/tmp/my.file'
