centos7 部署Prometheus+Grafana

1、下载部署包

https://link.zhihu.com/?target=https%3A//prometheus.io/download/

https://mirrors.tuna.tsinghua.edu.cn/github-release/prometheus/prometheus/

https://prometheus.io/download/

https://mirrors.tuna.tsinghua.edu.cn/grafana/yum/rpm/Packages/

 

 

组件介绍

node_exporter（用于监控每一台服务器的资源，采集agent，每一台都要装）

prometheus（数据源，装到主节点上）

grafana（可视化prometheus，装到主节点上）

 

2、部署安装

2.1、部署prometheus

wget https://mirrors.tuna.tsinghua.edu.cn/github-release/prometheus/prometheus/2.45.2%20_%202023-12-19/prometheus-2.45.2.linux-amd64.tar.gz --no-check-certificate

tar -zxvf prometheus-2.45.2.linux-amd64.tar.gz

#修改配置文件

vim prometheus.yml
static_configs:
- targets: ["localhost:9090"]
- job_name: 'linux-vm'
static_configs:
- targets: ['192.168.0.1:9100','192.168.0.2:9100','192.168.0.3:9100','192.168.0.4:9100','192.168.0.86:60023'] #填写所在的服务器ip端口，多个用 , 隔开
- job_name: 'TEST'
static_configs:
- targets: ['10.2.10.10:19100']
#临时后台启动

nohup ./prometheus --config.file=prometheus.yml   --web.listen-address="172.17.0.1:9090" --web.enable-lifecycle > /tmp/prometheus.log 2>&1 &

 

#设置启动服务

vim /usr/lib/systemd/system/prometheus.service
[Unit]
Description=prometheus
Documentation=https://prometheus.io/
After=network.target
[Service]
Type=simple
User=root
Group=root
ExecStart=/opt/workspace/prometheus/prometheus --config.file=/opt/workspace/prometheus/prometheus.yml --web.enable-lifecycle --web.listen-address=IP:9090
Restart=on-failure
[Install]
WantedBy=multi-user.target

2.2、部署grafana

2.2.1、普通安装

wget https://mirrors.tuna.tsinghua.edu.cn/grafana/yum/rpm/Packages/grafana-9.5.9-1.x86_64.rpm

rpm -ivh grafana-9.5.9-1.x86_64.rpm

sudo /bin/systemctl daemon-reload
sudo /bin/systemctl enable grafana-server.service
sudo /bin/systemctl start grafana-server.service

2.2.2、容器安装grafana

docker pull grafana/grafana

docker run -itd --name=grafana --restart=always -p 3000:3000 grafana/grafana

2.2.3、grafana配置面板

默认端口3000 admin/admin

配置采集数据源-datasources 

http://172.17.0.1:9090

导入需要的模板编号，下载地址

https://grafana.com/grafana/dashboards/12633-linux/

 12633

2.4、部署node_exporter

cp node_exporter /usr/local/bin/node_exporter
chmod 755 /usr/local/bin/node_exporter

./node_exporter --web.listen-address=192.168.0.1:9100

 

2.5 其他操作，grafana+Prometheus+node-export 容器化安装

/opt/workspace/prometheus.yml
# my global config
global:
scrape_interval: 15s # Set the scrape interval to every 15 seconds. Default is every 1 minute.
evaluation_interval: 15s # Evaluate rules every 15 seconds. The default is every 1 minute.
# scrape_timeout is set to the global default (10s).

# Alertmanager configuration
alerting:
alertmanagers:
- static_configs:
- targets:
# - alertmanager:9093

# Load rules once and periodically evaluate them according to the global 'evaluation_interval'.
rule_files:
# - "first_rules.yml"
# - "second_rules.yml"

# A scrape configuration containing exactly one endpoint to scrape:
# Here it's Prometheus itself.
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: ["172.17.0.1:9090"]

- job_name: 'S-Node'
static_configs:
- targets: ['10.22.33.222:19100','10.22.33.8:19100']
# pod-mon
- job_name: "docker-cadvisor"
static_configs:
- targets: ["172.17.0.1:8080"]
