安装集群过程
使用最新版本
wget https://github.com/VictoriaMetrics/VictoriaMetrics/releases/download/v1.91.3/victoria-metrics-linux-amd64-v1.91.3-cluster.tar.gz
解压
tar -xf victoria-metrics-freebsd-amd64-v1.91.3-cluster.tar.gz
[root@vms176 package]# ls
vminsert-prod vmselect-prod vmstorage-prod
修改名称
mv vminsert-prod vminsert
mv vmselect-prod vmselect
mv vmstorage-prod vmstorage
主机列表
192.168.26.176 vminsert
192.168.26.177 vmselect
192.168.26.178 vmstorage
scp传输
scp vminsert root@192.168.26.176:/usr/bin/
scp vmselect root@192.168.26.177:/usr/bin/
scp vmstorage root@192.168.26.178:/usr/bin/

vmui 也被集成到了 vmselect 组件中，我们可以通过路径 http://<vmselect>/select/0/vmui/ 进行访问
http://192.168.26.177:8481/select/0/vmui/#/?g0.range_input=30m&g0.end_input=2023-07-26T15%3A42%3A52&g0.relative_time=last_30_minutes&g0.tenantID=0
修改普罗米修斯
remote_write: # 远程写入到远程 VM 存储
- url: http://192.168.26.176:8480/insert/0/prometheus/
重启
systemctl restart prometheus.service
Grafana
添加数据源
