open-falcon falcon-api 服务搭建

本文主要是介绍open-falcon falcon-api 服务搭建，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

目的

部署 falcon-api
api 提供一系列接口
提供了用户，模板，组件， agent 间的交互

版本修改

modules/api/config/g.go

const (VERSION = "20200818"
)

编译

# make api
go build -o bin/api/falcon-api ./modules/api

创建目录

mkdir /apps/svr/falcon-plus/api/{bin,logs,data,config} -p

配置文件

/apps/svr/falcon-plus/api/config/cfg.json

}

启动测试

# /apps/svr/falcon-plus/api/bin/falcon-api -c /apps/svr/falcon-plus/api/config/cfg.json
INFO[0000] graph.Start ok

启动文件
