启动
说明
默认情况下，prometheus时序数据库(TSDB)数据的存储路径是 ./data，可以通过 --storage.tsdb.path 参数指定
可通过 --config.file 参数指定配置文件
注意
启动prometheus的时候需要加上 --web.enable-lifecycle 参数才可以执行热加载prometheus配置文件
否则会报错如下
$ curl -X POST http://127.0.0.1:9090/-/reload
Lifecycle API is not enabled.
./prometheus --config.file=prometheus.yml --web.enable-lifecycle
查看启动，prometheus默认监听9090端口
$ netstat -ntpl | grep prometheus
tcp6 0 0 :::9090 :::* LISTEN 1479/./prometheus
