go微服务框架Kratos的安装

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。

名字来源于:《战神》游戏以希腊神话为背景，讲述由凡人成为战神的奎托斯（Kratos）成为战神并展开弑神屠杀的冒险历程。

Goals

我们致力于提供完整的微服务研发体验，整合相关框架及工具后，微服务治理相关部分可对整体业务开发周期无感，从而更加聚焦于业务交付。对每位开发者而言，整套Kratos框架也是不错的学习仓库，可以了解和参考到bilibili在微服务方面的技术积累和经验。

Features

• 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

Requirments

Go version>=1.13

Installation

GO111MODULE=on && go get -u github.com/go-kratos/kratos/tool/kratos
cd $GOPATH/src
kratos new kratos-demo
通过 kratos new 会快速生成基于kratos库的脚手架代码，如生成 kratos-demo

Build & Run

cd kratos-demo/cmd
go build
./cmd -conf ../configs
打开浏览器访问：http://localhost:8000/kratos-demo/start，你会看到输出了Golang 大法好 ！！！

以上是官网介绍，有点简单，安装过程中会出现很多问题。

小伙伴们请参考下面的安装步骤！！！

Go微服务框架Kratos安装

特别注意：如果不是MacOS系统，需要自己进行手动安装protoc，用于生成的示例项目api目录下的proto文件并不会自动生成对应的.pb.go和.bm.go文件。
如果生成项目的时候并未使用--proto，则可以使用命令：

// generate all
kratos tool protoc api.proto
// generate gRPC
kratos tool protoc --grpc api.proto
// generate BM HTTP
kratos tool protoc --bm api.proto
// generate swagger
kratos tool protoc --swagger api.proto

对应生成 api.pb.go/api.bm.go/api.swagger.json 源文档。

1.安装protoc二进制文件

下载地址：https://github.com/google/protobuf/releases
1）、Linux系统（这里使用的是Ubuntu18.04）
下载后解压如下

进入到解压后的文件夹，执行如下命令：

sudo mv include/google /usr/local/include/

kratos@kratos:~/protoc-3.11.2-linux-x86_64$ sudo mv include/google /usr/local/include/
[sudo] kratos 的密码：

2）、Windows系统（这里使用的是win10）
下载后解压如下

把该文件夹放到你想要放的地方，然后在系统（或者用户）中添加bin目录环境变量，例：D:\goproject\protoc-3.11.2-win64\bin

2.代理设置

2.1、Linux

以下设置是临时修改PATH，下面有永久修改的方法，只需在文件最后把设置代理的命令添加进去即可。在任意路径下打开终端输出命令即可。只在当前命令窗口管用，若新开命令窗口，还要重新执行以下两条命令。也可以直接在系统中设置，Linux（自行网上搜索怎么设置）
1）、打开 go111module

export GO111MODULE=on

2）、默认代理是

GOPROXY="https://proxy.golang.org,direct"

以下代理建议用第一个

1、export GOPROXY=https://goproxy.cn/
2、export GOPROXY=https://goproxy.io/
3、export GOPROXY=https://mirrors.aliyun.com/goproxy/
4、export GOPROXY=https://athens.azurefd.net

3）、使用go env查看

linux下永久修改环境变量PATH的三种方式
只需把以上两条命令添加到文件最后即可，以下三种方法只是示例
方法一：.bashrc修改

1、进入当前用户的.bashrc文件：
vim ~/.bashrc
2、在.bashrc的最后一行添加相应的路径：
export PATH=/usr/local/bin:$PATH
3.使环境变量生效：
source ~/.bashrc
或者
. ~/.bashrc
注意：此种方法仅仅对当前用户有效

方法二：profile修改

1、进入系统的profile文件：
vim /etc/profile
2、找到设置PATH的行（不一定是最后一行），然后添加：
export PATH=/usr/local/bin:$PATH
3、重启linux系统
注意：此种方法对所有用户有效

方法三：environment修改

1、进入系统的environment文件：
vim /etc/environment
2、直接在PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin"加入相应路径即可：
PATH="/usr/local/sbin:/usr/local/bin:/usr/sbin:/usr/bin:/sbin:/bin"
3、重启linux系统
注意：此种方法对所有用户有效

2.2、Windows

1、 临时设置：
1）、打开 go111module

set GO111MODULE=on

2）、默认代理是

GOPROXY="https://proxy.golang.org,direct"

以下代理建议用第一个

1、set GOPROXY=https://goproxy.cn/
2、set GOPROXY=https://goproxy.io/
3、set GOPROXY=https://mirrors.aliyun.com/goproxy/
4、set GOPROXY=https://athens.azurefd.net

2、永久设置：
只需在环境变量中添加进去即可（这里是在系统环境变量中进行设置）

3.安装protobuf库文件

go get -u github.com/golang/protobuf/proto

kratos@kratos:~$ go get -u github.com/golang/protobuf/proto
go: finding github.com/golang/protobuf v1.3.2
go: downloading github.com/golang/protobuf v1.3.2
go: extracting github.com/golang/protobuf v1.3.2

4.安装goprotobuf插件

go get github.com/golang/protobuf/protoc-gen-go

kratos@kratos:~$ go get github.com/golang/protobuf/protoc-gen-go
kratos@kratos:~$ 

5.安装gogoprotobuf插件和依赖

//gogo
go get github.com/gogo/protobuf/protoc-gen-gogo

kratos@kratos:~$ go get github.com/gogo/protobuf/protoc-gen-gogo
go: finding github.com/gogo/protobuf v1.3.1

kratos@kratos:~$ go get github.com/gogo/protobuf/proto
kratos@kratos:~$ go get github.com/gogo/protobuf/gogoproto

7.安装kratos tool

go get -u github.com/bilibili/kratos/tool/kratos
已更新为

若GOPATH目录下没有src目录，则创建src目录
1）、Linux

进入到之前解压后的文件夹，执行如下命令：

mv bin/protoc /usr/local/bin/

kratos@kratos:~/protoc-3.11.2-linux-x86_64$ sudo mv bin/protoc /usr/local/bin/
[sudo] kratos 的密码：

cd $GOPATH/src
kratos new kratos-demo 或者 kratos new kratos-demo --proto

2）、Windows 这里是在系统环境变量中进行设置
（D:\goproject，这是我的Windows中的GOPATH目录）。以上步骤走完，会在D:\goproject目录下生成bin和pkg目录，如下图所示：

添加bin目录环境变量。例：D:\goproject\bin

新建kratos脚手架

kratos new是快速创建一个项目的命令，执行如下：

kratos new kratos-demo

即可快速在当前目录生成一个叫kratos-demo的项目。此外还支持指定owner和path，如下：

kratos new kratos-demo -o YourName -d YourPath

注意，kratos new默认是不会生成通过 protobuf 定义的grpc和bm示例代码的，如需生成请加–proto，如下：

kratos new kratos-demo -o YourName -d YourPath --proto

如只生成bm请加–http，如下：

kratos new kratos-demo -o YourName -d YourPath --http

如只生成grpc请加–grpc，如下：

kratos new kratos-demo -o YourName -d YourPath --grpc

通过 kratos new 会快速生成基于kratos库的脚手架代码，如生成 kratos-demo

kratos@kratos:~/go/src$ kratos new kratos-demo --proto

项目创建成功.

可以看到有可能会出现wire: generate failed，（为了确保protoc能够执行，删除kratos-demo目录并重新创建）此时，把生成在src目录中的 kratos-demo项目文件夹删掉，再重新执行以下命令生成kratos-demo目录：

kratos new kratos-demo --proto

kratos@kratos:~/go/src$ kratos new kratos-demo --proto

8.运行

使用如下命令运行项目
1、kratos run方式执行

cd kratos-demo
kratos run

kratos@kratos:~/go/src/kratos-demo$ kratos run
INFO 01/07-14:51:27.953 /home/kratos/go/src/kratos-demo/cmd/main.go:19 abc start

2、go build方式执行

cd kratos-demo/cmd
go build
./cmd -conf ../configs

kratos@kratos:~/go/src/kratos-demo$ cd cmd/
kratos@kratos:~/go/src/kratos-demo/cmd$ ls

kratos@kratos:~/go/src/kratos-demo/cmd$ go build
