3.protobuf

1.protobuf

1.解決git clone速度慢

sudo cp /etc/hosts /etc/hosts.backup 
curl -skX GET 'https://github.com.ipaddress.com/' | grep -oP '<th>IPv4 Addresses</th><td><ul class="comma-separated"><li>.*?</li>'| grep -oP '[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+'| awk '{print $1" github.com"}'> ~/myhosts
curl -skX GET 'https://fastly.net.ipaddress.com/github.global.ssl.fastly.net' | grep -oP '<th>IPv4 Addresses</th><td><ul class="comma-separated"><li>.*?</li>'| grep -oP '[0-9]+\.[0-9]+\.[0-9]+\.[0-9]+'| awk '{print $1" github.global.ssl.fastly.net"}'>> ~/myhosts

sudo /bin/bash -c 'cat ~/myhosts>>/etc/hosts'
cat /etc/hosts
sudo service networking restart
rm -f ~/myhosts

2.下載安裝

cd ~
git clone https://github.com/protocolbuffers/protobuf.git && ls | grep protobuf

# 開始安裝
cd ./protobuf 
git submodule update --init --recursive
./autogen.sh
./configure
make 
make check
sudo make install
sudo ldconfig # [很重要]刷新共享庫

3.測試

protoc --version
protoc --help
sudo cp /etc/hosts.backup /etc/hosts
sudo service networking restart

2.golang-protobuf

1.下載安裝

go get -u -v github.com/golang/protobuf/...
cd $GOPATH/bin && ls -la | grep protoc-gen-go

sudo tee -a /etc/protofile <<-'EOF'
export PATH=$PATH:$GOPATH/bin
EOF

source /etc/profile

2.測試

終端輸入protoc-，然後按下Tab鍵查看是否補全，補全即OK！

protoc-

4.gRPC

1.下載安裝

go get -u -v google.golang.org/grpc/...

2.測試

1.server啓動

cd $GOPATH/pkg/mod/google.golang.org/grpc*/examples/helloworld/*_server && ls
cd $GOPATH/pkg/mod/google.golang.org/grpc*/examples/helloworld/*_server &&  go run main.go

2.client啓動（另開一個終端）

cd $GOPATH/pkg/mod/google.golang.org/grpc*/examples/helloworld/*_client && ls
cd $GOPATH/pkg/mod/google.golang.org/grpc*/examples/helloworld/*_client &&  go run main.go

5.consul

1.下載安裝

cd ~ && sudo apt install -y wget unzip
wget https://releases.hashicorp.com/consul/1.7.2/consul_1.7.2_linux_amd64.zip && ls
sudo unzip ./consul_1.7.2_linux_amd64.zip -d /usr/local/bin/

2.測試

consul

6.micro

1.不支持consul註冊服務【默認mdns/etcd】

1.下載

go get -u -v github.com/micro/micro/...

2.編譯安裝

cd $GOPATH/pkg/mod/github.com/micro/ && ls |grep micro

選擇版本進入編譯到/bin/目錄下，名稱爲micro，源文件爲main.go

cd $GOPATH/pkg/mod/github.com/micro/[email protected]
sudo $GOROOT/bin/go build -o /bin/micro main.go

3.插件安裝

go get -u -v github.com/golang/protobuf/{proto,protoc-gen-go}
go get -u -v github.com/micro/protoc-gen-micro

4.測試

micro --version
micro --help

2.支持consul註冊服務

在生成的srv服務進行修改main.go即可
原main.go

package main

import (
	"github.com/micro/go-micro/util/log"
	"github.com/micro/go-micro"
	"micro/rpc/srv/handler"
	"micro/rpc/srv/subscriber"

	srv "micro/rpc/srv/proto/srv"
)

func main() {
	// New Service
	service := micro.NewService(
		micro.Name("go.micro.srv.srv"),
		micro.Version("latest"),
	)

	// Initialise service
	service.Init()

	// Register Handler
	srv.RegisterSrvHandler(service.Server(), new(handler.Srv))

	// Register Struct as Subscriber
	micro.RegisterSubscriber("go.micro.srv.srv", service.Server(), new(subscriber.Srv))

	// Register Function as Subscriber
	micro.RegisterSubscriber("go.micro.srv.srv", service.Server(), subscriber.Handler)

	// Run service
	if err := service.Run(); err != nil {
		log.Fatal(err)
	}
}

修改後【中文註釋部分即爲修改部分】：

package main

import (
	"micro/rpc/srv/handler"
	"micro/rpc/srv/subscriber"

	"github.com/micro/go-micro"
	"github.com/micro/go-micro/util/log"

	srv "micro/rpc/srv/proto/srv"

	"github.com/micro/go-micro/registry"          // 添加註冊插件
	"github.com/micro/go-plugins/registry/consul" // 添加註冊插件的consul支持
)

func main() {
	// consul註冊
	consulReg := consul.NewRegistry(
		registry.Addrs("127.0.0.1:8500"),
	)
	// New Service
	service := micro.NewService(
		micro.Name("go.micro.srv.srv"),
		micro.Version("latest"),
		micro.Registry(consulReg), // micro添加consul的註冊
	)

	// Initialise service
	service.Init()

	// Register Handler
	srv.RegisterSrvHandler(service.Server(), new(handler.Srv))

	// Register Struct as Subscriber
	micro.RegisterSubscriber("go.micro.srv.srv", service.Server(), new(subscriber.Srv))

	// Register Function as Subscriber
	micro.RegisterSubscriber("go.micro.srv.srv", service.Server(), subscriber.Handler)

	// Run service
	if err := service.Run(); err != nil {
		log.Fatal(err)
	}
}

重新run[consul 一定要開啓consul agent -dev]即可

go run main.go
