# 下载二进制包，X86架构，这里以v3.3.0版本为例
wget https://github.com/prometheus/prometheus/releases/download/v3.3.0/prometheus-3.3.0.linux-amd64.tar.gz

# 移动到/usr/local/下
mv prometheus-3.3.0.linux-amd64 /usr/local/prometheus

# 创建systemd服务配置文件
cat > /usr/lib/systemd/system/prometheus.service << EOF

Docker部署

docker run -d \
    --restart unless-stopped \
    --name prometheus-server \
    -p 9090:9090 \
    -v /usr/local/prometheus/prometheus.yml:/etc/prometheus/prometheus.yml \
    -v /usr/local/prometheus/data:/prometheus \
    prom/prometheus:latest \
    --storage.tsdb.retention.time=180d

k8s下部署

创建yaml资源清单文件

vim prometheus.yaml
