Example Playbook

安装zookeeper，默认端口2181：
- hosts: 192.168.77.129
  roles:
   - { role: zookeeper }

单机伪集群安装：
- hosts: 192.168.77.129
  vars:
   - zookeeper_hosts:
      - {'host': 192.168.77.129, 'id': 1, 'port': 2181, 'leader_port': '2888:3888'}
      - {'host': 192.168.77.129, 'id': 2, 'port': 2182, 'leader_port': '2889:3889'}
      - {'host': 192.168.77.129, 'id': 3, 'port': 2183, 'leader_port': '2890:3890'}

  roles:
   - { role: zookeeper, zookeeper_port: 2181 }
   - { role: zookeeper, zookeeper_port: 2182 }
   - { role: zookeeper, zookeeper_port: 2183 }

分布式安装：
全部默认
- hosts: 192.168.77.129 192.168.77.130 192.168.77.131
  vars:
    - zookeeper_hosts: "{{ play_hosts }}"
  roles:
     - { role: zookeeper }
指定id
- hosts: 192.168.77.129 192.168.77.130 192.168.77.131
  vars:
   - zookeeper_hosts:
      - {'host': 192.168.77.129, 'id': 1}
      - {'host': 192.168.77.130, 'id': 2}
      - {'host': 192.168.77.131, 'id': 3}

  roles:
   - { role: zookeeper}
端口自定义
- hosts: 192.168.77.129 192.168.77.130 192.168.77.131
  vars:
   - zookeeper_hosts:
      - {'host': 192.168.77.129, 'id': 1, 'port': 2182, 'leader_port': '2889:3889'}
      - {'host': 192.168.77.130, 'id': 2, 'port': 2182, 'leader_port': '2889:3889'}
      - {'host': 192.168.77.131, 'id': 3, 'port': 2182, 'leader_port': '2889:3889'}

  roles:
   - { role: zookeeper, zookeeper_port: 2182}
