influxdb 的安装（centos）

安装命令：

# for 64-bit systems
wget http://s3.amazonaws.com/influxdb/influxdb-latest-1.x86_64.rpm
sudo rpm -ivh influxdb-latest-1.x86_64.rpm

具体安装过程如下：

wget http://s3.amazonaws.com/influxdb/influxdb-latest-1.x86_64.rpm

中间碰到

user is not in the sudoers file.  This incident will be reported.

可以借鉴下面方式解决，或者直接用有root权限的账号执行。

http://www.linuxidc.com/Linux/2010-12/30386.htm 

 

启动服务

[root@localhost ~]# /etc/init.d/influxdb start
Setting ulimit -n 4096
Starting the process influxdb [ OK ]
influxdb process was started [ OK ]

 

由于这是一台本地测试虚机，我直接关闭了iptable

[root@localhost ~]# /etc/init.d/iptables stop
iptables: Setting chains to policy ACCEPT: filter          [  OK  ]
iptables: Flushing firewall rules:                         [  OK  ]
iptables: Unloading modules:                               [  OK  ]

这台虚机的ip是：192.168.62.128， 所以我访问默认的 8083 端口，就可以看到下面界面：

http://192.168.62.128:8083/

 

这里的用户名和密码 默认都是 root， 登录进去就可以创建一个数据库。

初始化数据，以及查询可以看下图：

我们先用 Write Point 增加数据，

输入的  Time Series Name  是 log_lines

Values 是 {"line":"tewtstestw 123213 2354325 ghj 郭红俊 "}

输出成功后，我们执行 查询： select * from log_lines ，就可以看到上图的查询结果。

 

一些用golang使用的代码：

 

package main

import (
    "fmt"
    "github.com/influxdb/influxdb/client"
)

func main() {

    c, err := client.NewClient(&client.ClientConfig{
        Host:     "192.168.62.128:8086",
        Username: "root",
        Password: "root",
        Database: "test1",
    })

    if err != nil {
        panic(err)
    }

    name := "ts10"

    series := &client.Series{
        Name:    name,
        Columns: []string{"value"},
        Points: [][]interface{}{
            {1.0},
        },
    }
    if err := c.WriteSeries([]*client.Series{series}); err != nil {
        panic(err)
    }

    result, err := c.Query("list series")
    if err != nil {
        panic(err)
    }

    fmt.Println(" list series ", result[0])

    result, err = c.Query("select * from " + name)
    if err != nil {
        panic(err)
    }

    fmt.Println(" select * from ", name, " ", result[0])

}
