## 安装influxdb1.x ##

wget https://dl.influxdata.com/influxdb/releases/influxdb-1.8.0.x86_64.rpm
    yum -y localinstall influxdb-1.8.0.x86_64.rpm

## 编辑配置文件 ##

最终修改效果项如下所示

bind-address = "0.0.0.0:8088"
    [meta]
      dir = "/var/lib/influxdb/meta"
    [data]
      dir = "/var/lib/influxdb/data"
      wal-dir = "/var/lib/influxdb/wal"
      cache-max-memory-size = "8g"
      series-id-set-cache-size = 100
    [coordinator]
      max-concurrent-queries = 0
      query-timeout = "0s"
      log-queries-after = "10s"
      max-select-series = 0
      max-select-buckets = 0
    [retention]
    [shard-precreation]
      advance-period = "10m"
    [monitor]
    [http]
      enabled = true
      bind-address = ":8086"
      log-enabled = false
      max-row-limit = 10000

## 启动服务 ##

systemctl start influxdb
    systemctl enable influxdb
    
    建库
    curl -XPOST http://192.168.241.13:8086/query --data-urlencode "q=CREATE DATABASE prometheus"
    或者
    influx -precision rfc3339
    create database prometheus;
    show databases;

## 准备remote\_storage\_adapter ##

对于业务比较大的环境Local storage是绝对满足不了的，那么就要用remote storage了。  
Prometheus的remote storage需要借助adapter实现，adapter会提供write url和read url给Prometheus，这样Prometheus获取到数据后就会先写到本地然后再调用write url写到远端。  
下载一个可执行文件remote\_storage\_adapter。  
GitHub地址：

https://github.com/prometheus/prometheus/blob/main/documentation/examples/remote_storage/remote_storage_adapter/README.md

需要安装一个go环境并进行build。我已经build好了，下载下面的地址可以直接用。

wget https://github.com/zyiqian/charts/blob/main/prometheus/remote_storage_adapter
    chmod +x remote_storage_adapter

## 手工启动 ##

nohup /usr/local/sbin/remote_storage_adapter 
    --influxdb-url=http://192.168.241.13:8086 
    --influxdb.database=prometheus 
    --influxdb.retention-policy=autogen >/var/log/remote_storage_adapter.log 2>&1 &

## 将remote\_storage\_adapter注册为系统服务 ##

cat>/lib/systemd/system/remote_storage_adapter.service<<EOF
    [Service]
    Restart=on-failure
    WorkingDirectory=/root/
    ExecStart=/usr/local/sbin/remote_storage_adapter --influxdb-url=http://192.168.241.13:8086/ --influxdb.database="prometheus" --influxdb.retention-policy=autogen
    [Install]
    WantedBy=multi-user.target
    EOF
    
    systemctl daemon-reload
    systemctl enable remote_storage_adapter
    systemctl start remote_storage_adapter
    systemctl status remote_storage_adapter

## 配置prometheus远程写入 ##

修改prometheus.yml中的配置remoteWrite和remoteRead

remote_write:
      - url: "http://192.168.241.13:8086/api/v1/prom/write?db=prometheus"
    remote_read:
      - url: "http://192.168.241.13:8086/api/v1/prom/read?db=prometheus"

## 查看Influxdb ##

# influx
    Connected to http://localhost:8086 version 1.8.0
    influxdb shell version: 1.8.0
    > show databases;
    name: databases
