Prometheus+Grafana部署配置

Prometheus安裝

下載Prometheus服務端

Download | PrometheusAn open-source monitoring system with a dimensional data model, flexible query language, efficient time series database and modern alerting approach.https://prometheus.io/download/

上傳至服務器，解壓

tar -zxvf prometheus-3.0.1.linux-amd64.tar.gz

cd prometheus-3.0.1.linux-amd64

運行

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

后臺運行

nohup?./prometheus --config.file=prometheus.yml &

當首次訪問9090端口時，時間序列數據的洪流如同宇宙背景輻射般撲面而來。

Grafana安裝

Grafana是一個可視化面板(Dashboard),有著非常漂亮的圖表和布局展示,功能齊全的度量儀表盤和圖形編輯器,支持Graphite、zabbix、InfluxDB、Prometheus

Prometheus被監控端安裝插件

下載插件（此處下載一個node 和 mysql插件）

Download | PrometheusAn open-source monitoring system with a dimensional data model, flexible query language, efficient time series database and modern alerting approach.https://prometheus.io/download/

在被監控端主機解壓這兩個文件

tar -zxvf node_exporter-1.8.2.linux-amd64.tar.gz?

???????????

node_exporter插件可直接運行cd node_exporter-1.8.2.linux-amd64

node_exporter插件可直接運行

cd node_exporter-1.8.2.linux-amd64

nohup ./node_exporter &

mysqld_exporter需要連接到MySQL,需要授權

mysqld_exporter插件需要創建一個用戶+密碼的文件

tar -zxvf mysqld_exporter-0.16.0.linux-amd64.tar.gz

cd mysqld_exporter-0.16.0.linux-amd64

mysql> use mysql;mysql> create user dbuser;

mysql> GRANT REPLICATION CLIENT, PROCESS ON *.* TO 'dbuser'@'localhost' identified by '123456';

mysql> GRANT SELECT ON performance_schema.* TO 'dbuser'@'localhost';

創建 .my.cnf 加入以下內容

[client]user=dbuserpassword=123456

啟動mysqld_exporter

nohup ./mysqld_exporter --config.my-cnf=.my.cnf &

Prometheus服務端添加被監控端

cd prometheus-3.0.1.linux-amd64

vi prometheus.yml? 加入- job_name: system-statusstatic_configs:- targets: ['192.168.126.50:9100']labels:instance: 7-7- job_name: mysql-statusstatic_configs:- targets: ['192.168.126.40:9104']labels:instance: 7-7-mysql
