In the example shown next, we are going to set up a Go environment to run InfluxDB with Go client.

1. Install Go.

Install Go by following the golang installation guide available at:

https://golang.org/doc/install

Set up GOROOT and GOBIN:

sudo apt install golang-go
export GOROOT=/usr/lib/go
export GOBIN=/usr/bin/go

Set up $GOPATH:

mkdir ~/go
export GOPATH=~/go
export PATH=$PATH:$GOPATH/bin
export PATH=$PATH:$GOROOT/bin

Check the Go version:

$ go version
go version go1.6.2 linux/amd64

2. Install the InfluxDB Go client library:

go get github.com/InfluxDB/InfluxDB

You should see a message similar to the following:

package github.com/InfluxDB/InfluxDB: code in directory /home/user/go/src/github.com/InfluxDB/InfluxDB expects import "github.com/influxdata/InfluxDB"

3. Write the Go program:

package main
import (
"log"
    "time"
    "github.com/influxdata/InfluxDB/client/v2"
)
const (
database  = "testdb"
username = "root"
password = "root"
)
func main() {
    c, err := client.NewHTTPClient(client.HTTPConfig{
       Addr:     "http://localhost:8086",
       Username: username,
       Password: password,
    })
// Create a new point batch
bp, err := client.NewBatchPoints(client.BatchPointsConfig{
       Database:  database,
       Precision: "s",
    })
// Create a point and add to batch
tags := map[string]string{}
    fields1 := map[string]interface{}{
"http": "GET /cgi-bin/try/ HTTP/1.0",
"status": 200,
"duration": 3395,
"ip": "192.168.2.20",
    }
    pt1, err := client.NewPoint("apachelog_go", tags, fields1, time.Unix(0, 1511361120000000000))
    bp.AddPoint(pt1)
    fields2 := map[string]interface{}{
"http": "GET / HTTP/1.0",
"status": 200,
"duration": 2216,
"ip": "127.0.0.1",
    }
    pt2, err := client.NewPoint("apachelog_go", tags, fields2, time.Unix(0, 1511361180000000000))
    bp.AddPoint(pt2)
// Write the batch
if err := c.Write(bp); err != nil {
       log.Fatal(err)
    }
 }
}

4. Run the Go program as follows:

go run goclientInfluxDBtest.go

Once the program has successfully run, you should see a new measurement—apachelog_go is created in the database and two data points are inserted.

> show measurements

apachelog_py
