这里记录下influx控制台的简单使用,如需更多功能请参考InfluxDB官方文档: https://docs.influxdata.com/influxdb/v1.1/
环境: CentOS6.5_x64 InfluxDB版本:1.1.0
执行如下命令:
service influxdb start示例如下:
[root@localhost ~]# service influxdb start Starting influxdb... influxdb process was started [ OK ] [root@localhost ~]# 启动控制台客户端在控制台执行influx即可启动InfluxDB cli,示例如下:
[root@localhost ~]# influx Visit https://enterprise.influxdata.com to register for updates, InfluxDB server management, and monitoring. Connected to http://localhost:8086 version 1.1.0 InfluxDB shell version: 1.1.0 >格式: show databases 示例如下:
> show databases; name: databases name ---- _internal 创建新数据库格式:
create database <dbname>说明: dbname : 数据库名称 示例如下:
> create database testdb; > show databases; name: databases name ---- _internal testdb > 删除数据库格式:
drop database <dbname>说明: dbname : 数据库名称 示例如下:
> drop database testdb; > show databases; name: databases name ---- _internal >格式: show measurements 示例如下:
> use testdb; Using database testdb > show measurements; 创建新表并添加数据InfluxDB没有提供单独的建表语句,可以通过以下方式创建数据库并添加数据。
格式:
insert <tbname>,<tags> <values> [timestamp]说明: tbname : 数据表名称 tags : 表的tag域 values : 表的value域 timestamp :当前数据的时间戳(可选,没有提供的话系统会自带添加)
示例如下:
> use testdb; Using database testdb > insert students,stuid=s123 score=89 > show measurements; name: measurements name ---- students 删除表格式:
drop measurement <tbname>说明: tbname : 数据表名称
示例如下:
> use testdb; Using database testdb > drop measurement students; > show measurements; >格式:
insert <tbname>,<tags> <values> [timestamp]说明: tbname : 数据表名称 tags : 表的tag域 values : 表的value域 timestamp :当前数据的时间戳(可选,没有提供的话系统会自带添加)
示例如下:
> insert students,stuid=s123 score=79 > insert students,stuid=s123 score=89 1488821368327436809 > select * from students name: students time score stuid ---- ----- ----- 1488821368327436809 89 s123 1488821404414227498 79 s123 查询格式:
select <fields> from <tbname> [ into_clause ] [ where_clause ] [ group_by_clause ] [ order_by_clause ] [ limit_clause ] [ offset_clause ] [ slimit_clause ] [ soffset_clause ]说明: fields : 要查询的字段,查询全部可以用* tbname : 数据表名称 into_clause : select ... into (可选) where_clause : where条件域(可选) group_by_clause : group by相关(可选) order_by_clause : order by相关(可选) limit_clause : limit相关(可选) offset_clause : offset相关(可选) slimit_clause : slimit相关(可选) soffset_clause : soffset相关(可选)
示例如下:
> use testdb; Using database testdb > show measurements; name: measurements name ---- students > select * from students name: students time score stuid ---- ----- ----- 1488821368327436809 89 s123 1488821404414227498 79 s123 1488822192864587535 69 s123 1488822196951305763 39 s123 > select * from students where score > 70; name: students time score stuid ---- ----- ----- 1488821368327436809 89 s123 1488821404414227498 79 s123 > select * from students where score > 70 limit 1; name: students time score stuid ---- ----- ----- 1488821368327436809 89 s123 > 更新tags 和 timestamp相同时数据会执行覆盖操作,相当于InfluxDB的更新操作。
示例如下:
> insert students,stuid=s123 score=39 > select * from students name: students time score stuid ---- ----- ----- 1488822338410283027 39 s123 > insert students,stuid=s123 score=99 1488822338410283027 > select * from students name: students time score stuid ---- ----- ----- 1488822338410283027 99 s123 > 删除格式:
delete from <tbname> [where_clause]说明: tbname : 表名称 where_clause : where条件(可选)
删除所有数据:
> delete from students; > select * from students; >删除指定条件的数据:
> select * from students; name: students time score stuid ---- ----- ----- 1488820352594964019 89 s123 1488820356463338534 79 s123 > delete from students where stuid='s123' and time=1488820352594964019; > select * from students; name: students time score stuid ---- ----- ----- 1488820356463338534 79 s123 >格式:
influx -execute '<query>'类似 mysql -e 的功能,示例代码如下:
[root@localhost ~]# influx -execute 'show databases' name: databases name ---- _internal testdb [root@localhost ~]# 指定查询结果以csv或json格式输出格式:
influx -format=[format]说明:
format : 启动格式,支持column,csv,json三种格式,默认为column
示例如下:
[root@localhost ~]# influx -format=csv Visit https://enterprise.influxdata.com to register for updates, InfluxDB server management, and monitoring. Connected to http://localhost:8086 version 1.1.0 InfluxDB shell version: 1.1.0 > show databases; name,name databases,_internal databases,testdb > exit [root@localhost ~]# influx -format=json Visit https://enterprise.influxdata.com to register for updates, InfluxDB server management, and monitoring. Connected to http://localhost:8086 version 1.1.0 InfluxDB shell version: 1.1.0 > show databases; {"results":[{"series":[{"name":"databases","columns":["name"],"values":[["_internal"],["testdb"]]}]}]} > exit [root@localhost ~]# influx -format=json -pretty Visit https://enterprise.influxdata.com to register for updates, InfluxDB server management, and monitoring. Connected to http://localhost:8086 version 1.1.0 InfluxDB shell version: 1.1.0 > show databases; { "results": [ { "series": [ { "name": "databases", "columns": [ "name" ], "values": [ [ "_internal" ], [ "testdb" ] ] } ] } ] } >
好,就这些了,希望对你有帮助。
