grpc和protoc的安装

protoc的安装：

   1. 安装grpc的相关依赖，执行以下命令：

    yum install -y gcc-c++ autoconf libtool

    yum groupinstall -y "Development Tools"

   2. 下载源码：

     

是用wget下载protobuf包

wget https://github.com/protocolbuffers/protobuf/releases/download/v3.10.0/protobuf-all-3.10.0.tar.gz

tar zvxf protobuf-all-3.10.0.tar.gz

cd protobuf-3.10.0/

./autogen.sh

./configure -prefix=/usr/local/

make

make install

ldconfig

  3. protoc-gen-go插件安装

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

cd /home/gopath/pkg/mod/github.com/golang/protobuf@v1.5.2/protoc-gen-go

go build

cp protoc-gen-go /usr/local/bin/

   至此protoc已经安装完成。

 

安装grpc

 

1.下载grpc及依赖库

git clone https://github.com/grpc/grpc-go.git $GOPATH/src/google.golang.org/grpc

git clone https://github.com/golang/net.git $GOPATH/src/golang.org/x/net

git clone https://github.com/golang/text.git $GOPATH/src/golang.org/x/text

git clone https://github.com/golang/sys.git $GOPATH/src/golang.org/x/sys

go get -u github.com/golang/protobuf/{proto,protoc-gen-go} //安装不了的话可以skip,等后面报错了再说

git clone https://github.com/protocolbuffers/protobuf-go.git $GOPATH/src/google.golang.org/protobuf

git clone https://github.com/google/go-genproto.git $GOPATH/src/google.golang.org/genproto

 

2.安装grpc

cd $GOPATH/src/

go install google.golang.org/grpc

基本上go install没有提示错误,grpc就算安装好了,我们现在拿grpc里的example来测试下

 

 

 

3.验证：

[root@localhost golang]# cd ../../google.golang.org/grpc/examples/helloworld/greeter_server/
[root@localhost greeter_server]# go run main.go
2022/02/22 02:14:14 server listening at [::]:50051
2022/02/22 02:14:55 Received: world

[root@localhost ~]# cd /home/gopath/src/google.golang.org/grpc/examples/helloworld/greeter_client/
[root@localhost greeter_client]# go run main.go
2022/02/22 02:14:55 Greeting: Hello world
