1.認證
influx
auth
admin

2. 查看
show databases; 查看所有數據庫
use data； 使用data這個數據庫
show measurements 查看所有表
show tag keys 查看所有表中的索引tag
show field keys from cpu 查看cpu表中有哪些field字段
show tag keys from cpu 查看表中有哪些字段是tag
show series from cpu; 查詢表中的點series
查詢單表的10條數據
select * from data limit 10
查詢表中的最大值
select max(*) from data
設置時間顯示格式，按條件查詢，這個是UTC時間
precision rfc3339
select * from CPU_ALL where time >= '2018-11-23 14:30:39' and time <= '2019-11-23 14:32:32' limit 10
需要在查詢語句的最后加上tz('Asia/Shanghai')，這樣查詢的時間才是糾正為中國時區顯示。
select * from CPU_ALL where time >= '2018-11-23 14:30:39' and time <= '2019-11-23 14:32:32' limit 10 tz('Asia/Shanghai')
查看某個時間下的數據
select * from CPU_ALL where "time" = 1551694910000000000
查詢特定字段數據
select * from table_name where "字段1" =~ /匹配值/
倒序查詢
select * from CPU_ALL order by time desc limit 10 tz('Asia/Shanghai')
查詢平均值
select mean(*) from CPU_ALL tz('Asia/Shanghai')
3. 刪除
drop measurement CPU_ALL 刪除單表數據
4. 查詢某個字段值的總和
