1，关于kratos
Kratos是bilibili开源的一套Go微服务框架，包含大量微服务相关框架及工具。
HTTP Blademaster：核心基于gin进行模块化设计，简单易用、核心足够轻量；
GRPC Warden：基于官方gRPC开发，集成discovery服务发现，并融合P2C负载均衡；
Cache：优雅的接口化设计，非常方便的缓存序列化，推荐结合代理模式overlord；
Database：集成MySQL/HBase/TiDB，添加熔断保护和统计支持，可快速发现数据层压力；
Config：方便易用的paladin sdk，可配合远程配置中心，实现配置版本管理和更新；
Log：类似zap的field实现高性能日志库，并结合log-agent实现远程日志管理；
Trace：基于opentracing，集成了全链路trace支持（gRPC/HTTP/MySQL/Redis/Memcached）；
Kratos Tool：工具链，可快速生成标准项目，或者通过Protobuf生成代码，非常便捷使用gRPC、HTTP、swagger文档；

2，使用 kratos new kratos-demo 一键创建项目
首先需要安装 golang ，这个不用说。
这里需要设置下goproxy。
https://goproxy.cn/
$ echo "export GO111MODULE=on" >> ~/.bashrc
$ echo "export GOPROXY=https://goproxy.cn" >> ~/.bashrc
$ source ~/.bashrc
然后再执行
GO111MODULE=on && go get -u github.com/go-kratos/kratos/tool/kratos
cd $GOPATH/src
kratos new kratos-demo
配置好代理之后嗖嗖的下载，比阿里云的源好用。没有404情况。
$ kratos new kratos-demo

安装工具：

报错，估计安装的版本不行，对不上。$ protoc --version
libprotoc 3.0.0grpc 没有弄明白，先创建一个简单的HTTP服务：
4，只创建HTTP服务
可以增加参数 --http 只创建一个http 服务，然后还是依赖些 grpc的生成的代码。

api.proto: File does not reside within any path specified using --proto_path (or -I). You must specify a --proto_path which encompasses this file. Note that the proto_path must be an exact prefix of the .proto file names -- protoc is too dumb to figure out when two paths (e.g. absolute and relative) are equivalent (it's harder than you think).
