一./etc/ansible/hosts

[webServers]192.168.2.100 http_port=8080192.168.2.200 http_port=8009 [web] web1 web2 [db] db1 db2 [app:children] web db

二./etc/ansible/hosts

[webServers]192.168.2.100 192.168.2.200 [webServers:vars]name=nginx

三.playbook中定义

- hosts: test  remote_user: root  vars:    - path: /usr/local/nginx/sbin/nginx    - var2: value2

四.命令行指定

[root@L ansible]# ansible-playbook -e 'http_port=80 name=nginx' test.yaml

五.独立文件

[root@L ansible]# vim vars.yamlvar1: httpdvar2: vsftpd

---- hosts: test  remote_user: root  vars_files:    vars.yaml  tasks:    - name: install httpd      yum : name={
   { var1 }}

 六.嵌套子变量

---- hosts: test  remote_user: root  tasks:    - name: create user      user: name={
   { item.name }} group={
    { item.group }}       with_items:            - { name: 'user1' , group: 'group1}            - { name: 'user1' , group: 'group1}
