ansible小计

一、忽略hosts，只在一台机器上执行：

/usr/local/bin/ansible-playbook /app/ansiblecfg/ztr/ent_extract.yml --limit=10.128.109.196

二、批量推送密钥

在ansible管理主机生成密钥id_rsa.pub，使用如下playbook推送密钥至受控主机节点

#push key to remote server
- hosts: nengqian
  user: ccssoft
  tasks:
   - name: ssh-copy
     authorized_key: user=ccssoft key="{{ lookup('file', '/home/shdxspark/.ssh/id_rsa.pub') }}"
     tags:
        - sshkey

user为远程主机账号，key为管理主机生成的公钥key
