创建 Influxdb数据库
[[email protected] software]# influx Connected to http://localhost:8086 version 1.7.6 InfluxDB shell version: 1.7.6 Enter an InfluxQL query > create databese telegraf > create database jmeter > show databases name: databases name ---- _internal telegraf jmeter > CREATE USER root WITH PASSWORD ‘123456‘ WITH ALL PRIVILEGES # (创建一个新的管理员用户) > GRANT ALL PRIVILEGES TO root #为一个已有用户授权管理员权限 > exit
配置Telegraf
[[email protected] software]# vi /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 = "" [[email protected]_172_102_centos tools]# systemctl restart telegraf
检查Telegraf配置
## 转态是running说明配置加载成功
[[email protected] software]# service telegraf status

telegrfa默认开启下列几项系统性能收集，也可以通过配置文件自定义收集应用服务性能数据
安装配置完后，进到influxdb的telegraf数据库里面可以看到几张表，如下：
安装Grafana
wget https://dl.grafana.com/oss/release/grafana-6.2.3-1.x86_64.rpm
yum localinstall grafana-6.2.3-1.x86_64.rpm
安装完成后启动服务：systemctl start grafana-server，service grafana-server restart(重启)，记住要关闭防火墙喔，systemctl stop firewalld.service（临时关闭）和systemctl disable firewalld.service（禁止开机启动）systemctl status firewalld.service(查看防火墙状态)
然后访问，ip+3000端口，默认用户名和密码是admin;
通过命令getenforce来查看一下SELinux的状态，
安装好了grafana之后，我们可以配置一下grafana从influxdb中读取数据，从设置->Data Sources然后进行如下的配置：
