安装proto

下载地址：https://github.com/protocolbuffers/protobuf/releases

下载解压

wget https://github.com/protocolbuffers/protobuf/releases/download/v26.1/protoc-26.1-linux-x86_64.zip

unzip protoc-26.1-linux-x86_64.zip

我们把protoc放在/usr/local/bin可执行程序目录中，这样全局都可以访问到，同时把include目录的内容也复制到/usr/local/include/中

sudo mv bin/protoc /usr/local/bin
sudo mv include/google /usr/local/include
# 查看是否安装成功
protoc --version # libprotoc 25.3

# 安装插件
sudo go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
sudo go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest

go get -u google.golang.org/protobuf/cmd/protoc-gen-go
sudo go install google.golang.org/protobuf/cmd/protoc-gen-go

go get -u google.golang.org/grpc/cmd/protoc-gen-go-grpc
sudo go install google.golang.org/grpc/cmd/protoc-gen-go-grpc

# 检查protoc-gen-go 是否安装成功
protoc-gen-go --version

编译proto

app.proto

syntax = "proto3";
option go_package = "./app";
package app;

message Person {
  int32 age = 1;
  string name = 2;
}

message User{
  Person person = 3;
  int32 weight = 180;
}

protoc --go_out=./ *proto

grpc

protoc --go_grpc_out=. *.proto
