使用SHOW DATABASE Scurl命令验证InfluxDB是否已启动并正在运行: curl “http://localhost:8086/query?q=show+databases” 如果InfluxDB正在运行,您应该看到一个包含_internal数据库的对象: 这里也附带一个python验证demo #!/usr/bin/python # -*- coding: UTF-8 -*- import os data = 'http://localhost:80...

就query,write_points操作来说,如果操作执行未调用switch_database函数,切换到目标数据库,可以在调用query,write_points函数时,可以指定要操作的数据库,如下 client.query('show measurements;', database='mytestdb') client.write_points(json_body, database='mytestdb') points参数值,可以不指定 time,这样采用...
温馨提示: 使用 influx query 命令后如果想要退出查询, 则可以按下 ctrl + d。 使用kubectl 在 Kubernetes 部署 InfluxDB 1.X 描述: 在k8s集群中可能我们常常会使用kubectl客户端工具指定资源清单的进行apply以部署相应资源,此处我们将演示以资源清单方式部署 InfluxDB 1.X。 温馨提示: 当前【2022年6月7日 19:...
