Ubantu安装Prometheus、Grafana、node_exporter、elasticsearch_exporter监
Prometheus安装更新体系包索引：apt-get update && apt-get upgrade -y
官网下载Prometheus: Prometheus
命令下载：wget https://github.com/prometheus/prometheus/releases/download/vX.X.X/prometheus-X.X.X.linux-amd64.tar.gz
上传并解压
修改prometheus.yml
scrape_configs:
# The job name is added as a label `job=<job_name>` to any timeseries scraped from this config.
- job_name: "prometheus"
# metrics_path defaults to '/metrics'
# scheme defaults to 'http'.
static_configs:
- targets: ["localhost:9090"]
- job_name: 'elasticsearch' # 监控ElasticSearch的job名称，自定义即可
scrape_interval: 60s
scrape_timeout:30s
metrics_path: "/metrics" # 监控后缀
static_configs:
- targets: ["192.168.xxx.xxx:9114"] # 刚刚配置的elasticsearch_exporter监控地址
- job_name: 'Linux'
scrape_interval: 60s
scrape_timeout:30s
metrics_path: "/metrics"
static_configs:
- targets: ["192.168.xxx.xxx:9100"]
后台启动：nohup ./prometheus --config.file=prometheus.yml & (留意这里–有两个)
prometheus 默认端口为9090，假如想切换一个端口，可以在启动的时间直接指定，如下：
./prometheus --config.file=prometheus.yml --web.listen-address=:9091 &
验证：http:ip:9090 点击targets
设置快速启动：
vim /etc/systemd/system/prometheus .service
Requires=network.target
After=network.target
Type=simple
WorkingDirectory=/usr/local/prometheus
ExecStart=/usr/local/prometheus/prometheus --log.level=info
TimeoutSec=30
Restart=always
WantedBy=multi-user.target
systemctl daemon-reload
systemctl start prometheus.service
systemctl status prometheus.service
Grafana安装
直接官网安装：Grafana安装
验证：http:ip:3000 默认账号暗码：admin 不改就点击skip
在Grafana Web界面中，点击“Connections” > “Data Sources”。添加一个新的数据源并选择Prometheus。提供你的Prometheus服务器的URL（例如，http://your_domain:9090）并保存设置。

Grafana 的模板商店:Grafana模板商店
设置快速启动：
sudo vim /lib/systemd/system/grafana-server.service
Description=Grafana
After=network-online.target
ExecStart=/usr/local/grafana/bin/grafana-server -homepath /usr/local/grafana
WantedBy=multi-user.target
sudo systemctl daemon-reload
sudo systemctl start grafana-server
sudo systemctl enable grafana-server
node_exporter安装
下载地址：node_exporter
上传并解压然后启动: nohup ./node_exporter &
需要重启Prometheus
设置快速启动：
vim /etc/systemd/system/node_exporter.service
Description=prometheus node_exporter Daemon
Documentation=https://github.com/prometheus/node_exporter

Restart=always
WantedBy=multi-user.target
systemctl daemon-reload
systemctl start node_exporter.service
systemctl status node_exporter.service
elasticsearch_exporter安装
下载地址：elasticsearch_exporter
上传并解压
设置文件是deployment.yml 一般不用改啥
然后启动: nohup ./elasticsearch_exporter &
