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'}
