注：
1、influxdb要求1.4以上版本
2、prometheus用默认的存储方式在grafana上可方便计算空间使用率等的信息（涉及计算），切到influxdb后目前还不知道如何转换

rpm -i influxdb-1.6.3.x86_64.rpm

service influxdb start

chkconfig --level 35 influxdb on

influx

create database prometheus;
create user icinga2 with password ‘xxxx‘;
grant all on prometheus to icinga;
show retention policies on prometheus;
alter retention policy "autogen" on "prometheus" duration 365d default;
quit

vi /space/prometheus/prometheus.yml

remote_write:

• url: "http://localhost:8086/api/v1/prom/write?db=prometheus"

remote_read:

• url: "http://localhost:8086/api/v1/prom/read?db=prometheus"

:wq

/space/prometheus/prometheus --config.file=/space/prometheus/prometheus.yml

prometheus存数据到influxdb数据库
