安装后配置文件

/root/.influxdbv2

图形界面创建数据库(上面初始化的时候已经创建好数据库了，如下想再创建数据库就通过这里创建)

1、创建数据库

2、创建用户并把数据库授权给用户

在程序中调用influxdb

[root@k8s-gateway-dev influxdb]# cat  /project/deepctl-statistic/etc/config.toml 
[Basic]Name = "deepctl_statistic"Port = 62213[Mysql] MysqlHost = "39.97.184.6:3306"MysqlUser = "root"MysqlPass = "Clouddeep@8890"MysqlDb = "deepctl_manager"MysqlEncrypt = 0[Redis]RedisHost = "39.97.184.6:6379"RedisPass = "Clouddeep&&Redis9910"RedisDb = 0RedisEncrypt = 0[InfluxDB]# 连接的influxdb地址InfluxDBHost = "http://127.0.0.1:8086"  # 用户TonkenInfluxDBToken = "TYP1RgqjU_8w9SMM2t9u0CX446BesTC0PPr6ELKvxMk3DQFUR_Q8HmtzDb943l1gRmBhmbqDFvv24G1kzVEFxQ=="   # 初始化时指定的组织名称InfluxDBOrg = "clouddeep"# 数据库名称InfluxDBBucket = "deeptun"InfluxDBEncrypt = 0
