nfs服务客户端三台主机
centos7 10.0.0.7、centos6 10.0.0.8、centos7 10.0.0.9
此时在批量启动的时候需要进行判断，因为centos6，centos7启动命令不一样
判断的格式
- hosts: nfs_client
tasks:
- name: boot centos7 nfs
shell: systemctl start nfs 
判断: 如果是centos7 ???
- name: boot centos6 nfs 
shell: /etc/init.d/nfs start 
判断: 如果是centos6 ???

setup模块：收集远程主机信息
语法：
[root@m01 ansible_playbook]#ansible 172.16.1.41 -m setup -a "filter=ansible_hostname"
172.16.1.41 | SUCCESS => {
 "ansible_facts": {
  "ansible_hostname": "backup", 
  "discovered_interpreter_python": "/usr/bin/python"
 }, 
 "changed": false
}

# filter 过滤 筛选

- hosts: rsync
 tasks:
 - name: touch file
  file: path=/etc/oldboy01.txt state=touch
  when: (ansible_eth1.ipv4.address == "172.16.1.41")

- hosts: rsync
 tasks:
 - name: touch file
  file: path=/etc/oldboy01.txt state=touch
  when: (ansible_eth1["ipv4"]["address"] == "172.16.1.41")

[root@m01 ansible_playbook]#vim test_判断功能.yaml
- hosts: nfs_client
