10.47.92.186 需要安裝的軟件:grafana,prometheus
10.81.44.176 需要安裝的軟件:node_exporter
一.安裝grafana(下載地址https://grafana.com/grafana/download)
在10.47.92.186服務器上執行以下操作
1.wget https://s3-us-west-2.amazonaws.com/grafana-releases/release/grafana-5.3.0-1.x86_64.rpm
rpm -ivh grafana-5.3.0-1.x86_64.rpm
yum install urw-fonts -y
rpm -ivh grafana-5.3.0-1.x86_64.rpm
2.vi /etc/grafana/grafana.ini,修改如下值
;#################################### Dashboard JSON files ##########################
[dashboards.json]
;enabled = true
;path = /var/lib/grafana/dashboards
3.grafana-dashboards下載地址https://github.com/percona/grafana-dashboards
將grafana-dashboards/dashboards目錄下文件上傳到/var/lib/grafana/dashboards
4.systemctl daemon-reload
service grafana-server start
5.訪問地址http://10.47.92.186:3000
二.安裝node_exporter
在10.81.44.176服務器上執行以下操作(注意node_exporter的版本號必須是0.15.0,否則下面的system overview將搜集不到數據)
1.cd /app
tar xvf node_exporter-0.15.0.linux-amd64.tar.gz
nohup /app/node_exporter-0.15.0.linux-amd64/node_exporter & > /dev/null &
2.判斷node_exporter是否啟動成功
root@iZbp1dey0fcjb1t6dhtnafZ:[/app]netstat -anp | grep 9100
tcp6 0 0 :::9100 :::* LISTEN 25980/node_exporter
三.安裝prometheus(下載地址https://github.com/prometheus/prometheus/releases)
在10.47.92.186服務器上執行以下操作
1.tar xvf prometheus-2.4.3.linux-amd64.tar.gz
cd prometheus-2.4.3.linux-amd64
2.vi prometheus.yml,其中10.47.92.186為數據庫服務器IP,添加以下紅色字體部分
global:
scrape_interval: 15s
evaluation_interval: 30s
scrape_timeout: 10s
external_labels:
monitor: 'prometheus-server'
rule_files:
- 'prometheus.rules.yml'
scrape_configs:
- job_name: zxy9_db_linux
static_configs:
- targets: ['10.81.44.176:9100']
labels:
instance: zxy9_db
3.啟動prometheus
cd /app/prometheus-2.4.3.linux-amd64
nohup ./prometheus & > /dev/null &
4.訪問prometheus,默認端口9090,10.47.92.186為prometheus服務器IP
四.配置grafana與prometheus的關聯性
1.登陸grafana,訪問地址為http://10.47.92.186:3000/,10.47.92.186為grafana服務器IP
2.導入dashboard
點擊Upload .json File，選擇具體的模版
dashboard的json文件是System_Overview.json文件鏈接如下
導入成功之后，可以看到導入成功后的dashboard
