ubuntu 20.04虚拟机安装GRPC

根据文档进行clone和编译：https://github.com/grpc/grpc/blob/master/BUILDING.md

首先安装依赖环境：

apt-get install build-essential autoconf libtool pkg-config
apt-get install cmake
apt-get install clang libc++-dev

然后将gitee上的镜像源码clone到本地：

git clone https://gitee.com/chuansao825/grpc.git

然后

cd grpc

修改 .gitmodules 文件，将其中每一项github的url找出，然后拉取github的原仓库到自己的gitee仓库，并替换url。即

[submodule "third_party/abseil-cpp"]
	path = third_party/abseil-cpp
	url = https://gitee.com/chuansao825/abseil-cpp.git
[submodule "third_party/benchmark"]
	path = third_party/benchmark
	url = https://gitee.com/chuansao825/benchmark.git
[submodule "third_party/bloaty"]
	path = third_party/bloaty
	url = https://gitee.com/chuansao825/bloaty.git
[submodule "third_party/boringssl-with-bazel"]
	path = third_party/boringssl-with-bazel
	url = https://gitee.com/chuansao825/boringssl.git
[submodule "third_party/cares/cares"]
	path = third_party/cares/cares
	url = https://gitee.com/chuansao825/c-ares.git
[submodule "third_party/envoy-api"]
	path = third_party/envoy-api
	url = https://gitee.com/chuansao825/data-plane-api.git
[submodule "third_party/googleapis"]
	path = third_party/googleapis
	url = https://gitee.com/chuansao825/googleapis.git
[submodule "third_party/googletest"]
	path = third_party/googletest
	url = https://gitee.com/chuansao825/googletest.git
[submodule "third_party/libuv"]
	path = third_party/libuv
	url = https://gitee.com/chuansao825/libuv.git
[submodule "third_party/opencensus-proto"]
	path = third_party/opencensus-proto
	url = https://gitee.com/chuansao825/opencensus-proto.git
[submodule "third_party/opentelemetry"]
	path = third_party/opentelemetry
	url = https://gitee.com/chuansao825/opentelemetry-proto.git
[submodule "third_party/protobuf"]
	path = third_party/protobuf
	url = https://gitee.com/chuansao825/protobuf.git
[submodule "third_party/protoc-gen-validate"]
	path = third_party/protoc-gen-validate
	url = https://gitee.com/chuansao825/protoc-gen-validate.git
[submodule "third_party/re2"]
	path = third_party/re2
	url = https://gitee.com/chuansao825/re2.git
[submodule "third_party/xds"]
	path = third_party/xds
	url = https://gitee.com/chuansao825/xds.git
[submodule "third_party/zlib"]
	path = third_party/zlib
	url = https://gitee.com/chuansao825/zlib.git
	# When using CMake to build, the zlib submodule ends up with a
	# generated file that makes Git consider the submodule dirty. This
	# state can be ignored for day-to-day development on gRPC.
	ignore = dirty

并同步更新子模块的url：

git submodule sync

然后执行

git submodule update --init 

当子模块成功安装后，使用CMAKE进行Build。

mkdir -p cmake/build
cd cmake/build
cmake ../..
make

(make这一步速度很慢)
build成功：

然后进行install。首先要build并install子模块，根据官方给的脚本：

得到结果

为了测试是否安装成功，在上述生产的example的目录下使用两个终端先后开启server和client，如下所示：
