yum localinstall influxdb-1.0.2.x8664.rpm
systemctl start influxd

在Ubuntu上

wget https://dl.influxdata.com/influxdb/releases/influxdb_1.0.2_amd64.deb
sudo dpkg -i influxdb_1.2.4_amd64.deb
sudo systemctl start influxdb

telegraf 安装

wget http://get.influxdb.org/telegraf/telegraf-0.11.1-1.x86_64.rpm
yum localinstall telegraf-0.11.1-1.x86_64.rpm

在Ubuntu上

wget https://dl.influxdata.com/telegraf/releases/telegraf_0.11.1-1_amd64.deb
sudo dpkg -i telegraf_0.11.1-1_amd64.deb
sudo systemctl start telegraf

创建 Influxdb数据库

[root@VM_172_102_centos tools]# influx
Visit https://enterprise.influxdata.com to register for updates, InfluxDB server management, and monitoring.
Connected to http://localhost:8086 version 1.0.2
InfluxDB shell version: 1.0.2
> create database telegraf
> show databases

telegraf> exit

配置Telegraf

[root@VM_172_102_centos tools]# vim /etc/telegraf/telegraf.conf
## 修改内容如下
[[outputs.influxdb]]urls = ["http://localhost:8086"]  #infulxdb地址database = "telegraf" #数据库precision = "s"timeout = "5s"username = "admin" #帐号password = "admin" #密码retention_policy = ""[root@VM_172_102_centos tools]# systemctl restart telegraf

检查Telegraf配置

## 转态是running说明配置加载成功
[root@VM_172_102_centos tools]# service telegraf status

Active: failed: 附上由retention policy not found: default引起的配置错误。这里实在的坑，下载后的默认配置是default要改成""。（ retention_policy = ""）
