可以使用 Ambari API 来实现通过 Python 脚本登录 Ambari 页面并开启关闭各服务。以下是一个示例代码:
```python
import requests
import json
ambari_user = 'admin'
ambari_password = 'admin'
ambari_host = 'localhost'
ambari_port = '8080'
ambari_url = 'http://' + ambari_host + ':' + ambari_port
# Authenticate with Ambari
session = requests.Session()
session.auth = (ambari_user, ambari_password)
session.headers.update({'X-Requested-By': 'ambari'})
# Get a list of all services
response = session.get(ambari_url + '/api/v1/clusters/<cluster_name>/services')
services = json.loads(response.text)
# Start or stop a service
def change_service_state(service_name, state):
data = '{"RequestInfo":{"context":"Change ' + service_name + ' to ' + state + ' state"},"Body":{"ServiceInfo":{"state":"' + state + '"}}}'
response = session.put(ambari_url + '/api/v1/clusters/<cluster_name>/services/' + service_name, data=data)
print('Service ' + service_name + ' is now ' + state)
# Example usage: Start HDFS service
change_service_state('HDFS', 'STARTED')
# Example usage: Stop Hive service
change_service_state('HIVE', 'INSTALLED')
```
注意替换 `<cluster_name>` 为你的集群名称。此外,你还需要根据实际情况替换 Ambari 的用户名、密码、主机名和端口号。
