Prometheus+node_exporter+Grafana+Altermanager搭建部署K8S集群节点可视化监控告警平台

1. 实验服务器

提前开启防火墙端口，General：3000，Prometheus：9090，node_exporter：9100

2. m1服务器，安装Prometheus

# 下载 wget https://github.com/prometheus/prometheus/releases/download/v2.34.0/prometheus-2.34.0.linux-amd64.tar.gz # 解压 tar -zxvf prometheus-2.34.0.linux-amd64.tar.gz -C /usr/local/ # 更名 cd /usr/local/ && mv prometheus-2.34.0.linux-amd64 prometheus && cd prometheus

2.1创建prometheus.service配置文件

vi /usr/lib/systemd/system/prometheus.service

2.2 prometheus.service配置文件内，输入以下配置，退出并保存

cat > /usr/lib/systemd/system/prometheus.service << EOF [Unit] Description=prometheus After=network.target [Service] Type=simple User=root ExecStart=/usr/local/prometheus/prometheus --config.file=/usr/local/prometheus/prometheus.yml --storage.tsdb.path=/data/prometheus --storage.tsdb.retention=15d --log.level=info Restart=on-failure [Install] WantedBy=multi-user.target EOF

2.3启动prometheus服务

systemctl daemon-reload && systemctl start prometheus && systemctl enable prometheus && systemctl status prometheus

2.4查看prometheus服务进程

netstat -lntp | grep prometheus

3. m1服务器，安装node_exporter

# 下载 wget https://github.com/prometheus/node_exporter/releases/download/v1.3.1/node_exporter-1.3.1.linux-amd64.tar.gz # 解压 tar -zxvf node_exporter-1.3.1.linux-amd64.tar.gz -C /usr/local/ # 更名 cd /usr/local && mv node_exporter-1.3.1.linux-amd64 node_exporter && cd node_exporter

• 3.1创建启动node_exproter的配置文件

• vi /usr/lib/systemd/system/node_exporter.service

  3.2 node_exproter配置文件内，输入以下配置，退出并保存

  cat > /usr/lib/systemd/system/node_exporter.service << EOF [Unit] Description=node_exporter Documentation=https://prometheus.io/ After=network.target [Service] Type=simple User=root ExecStart=/usr/local/node_exporter/node_exporter Restart=on-failure [Install] WantedBy=multi-user.target EOF

• 启动node_exproter服务

systemctl daemon-reload && systemctl start node_exporter && systemctl enable node_exporter && systemctl status node_exporter
