ExecStart=/opt/aspire/product/prometheus/prometheus/prometheus --web.listen-address=:9090 --storage.tsdb.retention=30d --storage.tsdb.path=/data/prometheusData --web.enable-lifecycle --config.file=/opt/aspire/product/prometheus/prometheus/prometheus.yml
--web.listen-address=:9090? ? ##启动端口
--storage.tsdb.retention=30d? ?##保存数据时间
--storage.tsdb.path=/data/prometheusData? ? ?## 指定data 保存位置
当 要切换 保存数据位置的时候，如果 prometheus.service 配置文件中添加了
--storage.tsdb.path=/data/prometheusData? ，如果没效果，还是 之前的data保存数据，那么可能需要? ?停掉? Prometheus ，然后，删除 prometheus下的? data目录，然后 重启 Prometheus。
