influxdb基础入门

1.下载

wget https://dl.influxdata.com/influxdb/releases/influxdb-1.7.8_linux_amd64.tar.gz

2.解压

tar zxvf influxdb-1.7.8_linux_amd64.tar.gz

3.创建目录

mkdir -p /home/fengjun/influxdb/data

mkdir -p /home/fengjun/influxdb/log

mkdir -p /home/fengjun/influxdb/meta

mkdir -p /home/fengjun/influxdb/wal

4.修改配置

进入解压后的influxdb-1.7.8-1/etc/influxdb目录，配置indluxdb.conf

启动influxdb服务器

[fengjun@hadoop101 bin]$ ./influxd -config ../../etc/influxdb/influxdb.conf

启动influxdb客户端

[fengjun@hadoop101 bin]$ ./influx

> create database influxdb
> show databases

> use influxdb;

数据保留策略

 创建 create retention policy "influx_retention" on "influxdb" duration 30d replication 1 default

查看 show retention policies on influxdb

修改 alter retention policy "influx_retention" on influxdb duration 15d

删除 drop retention policy "influx_retention" on influxdb

表增删查操作

显示所有表

> show measurements

> insert weather,altitude=1000,area=北 temperature=11,humidity=4
> insert weather,altitude=500,area=北 temperature=18,humidity=5
> select * from weather

设置以下时间格式

> precision rfc3339

删除表

> drop measurement weather
> show measurements

influxdb插入语句怎么自动区分表名，tag，field，其实是用空格。 

> show tag keys from weather

> show field keys from weather

插入>insert weather,altitude=613,area=东 humidity=12,temperature=12

创建用户
> show users
user admin
---- -----

> create user influx with password 'influxdb'

> create user "admin" with password 'admin' with all privileges;

> show users;
user   admin
----   -----
influx false
admin  true
 

设置用户密码

> set password for influx = 'influx'

删除用户
> drop user admin
 

数据库访问权限

用户授权

授权用户数据库操作权限

> grant all privileges on influxdb to influx

赋予用户管理员权限

> grant all privileges to influx

撤销用户数据库操作权限

> revoke all privileges on influxdb from influx

撤销用户管理员权限

> revoke all privileges from influx

设置登录密码验证,进入influxdb-1.7.8-1/etc/influxdb目录，配置indluxdb.conf

将auth-enabled 改为true并去除#号注释

重启服务器:[fengjun@hadoop101 bin]$ ./influxd -config ../../etc/influxdb/influxdb.conf

客户端登录服务器，需要密码

[fengjun@hadoop101 bin]$ ./influx -username influx -password influx

Grafana安装部署

1.下载

[fengjun@hadoop101 software]$ wget https://dl.grafana.com/oss/release/grafana-7.2.0.linux-amd64.tar.gz

2.解压

[fengjun@hadoop101 software]$ tar -zxvf grafana-7.2.0.linux-amd64.tar.gz

3.启动服务

[fengjun@hadoop101 bin]$ ./grafana-server web

4.外网访问

输入本机ip和端口在浏览器访问http://192.168.224.129:3000/

输入账号admin，密码admin
