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"
