influxDB
一、安装influxDB
安装环境： OS X Yosemite， 使用brew命令安装
brew install influxdb执行结果:
➜ ~ brew install influxdb
==> Downloading https://homebrew.bintray.com/bottles/influxdb-0.13.0.yosemite.bo
######################################################################## 100.0%
==> Pouring influxdb-0.13.0.yosemite.bottle.tar.gz
==> Caveats
To have launchd start influxdb now and restart at login:
brew services start influxdb
Or, if you don't want/need a background service you can just run:
influxd -config /usr/local/etc/influxdb.conf
==> Summary
/usr/local/Cellar/influxdb/0.13.0: 6 files, 48.7M
➜ ~启动influxdb
influxd -config /usr/local/etc/influxdb.conf执行结果ßß：
