+# exhook-svr-go
+
+This is a demo server written in go for exhook
+
+## Prerequisites
+
+- [Go](https://golang.org) (any one of the three latest major)
+- [Protocol buffer](https://developers.google.com/protocol-buffers) **compiler**, `protoc`
+    For installation instructions, see
+    [Protocol Buffer Compiler Installation](https://grpc.io/docs/protoc-installation/).
+- **Go plugins** for the protocol compiler:
+    - Install the protocol compiler plugins for Go using the following commands:
+    ```
+    export GO111MODULE=on  # Enable module mode
+    go install google.golang.org/protobuf/cmd/protoc-gen-go@latest
+    go install google.golang.org/grpc/cmd/protoc-gen-go-grpc@latest
+    ```
+
+    - Update your PATH so that the protoc compiler can find the plugins:
+    ```
+    export PATH="$PATH:$(go env GOPATH)/bin"
+    ```
+
+## Run
+
+Try to compile the `*.proto` files:
+
+```
+protoc --go_out=. --go_opt=paths=source_relative \
+    --go-grpc_out=. --go-grpc_opt=paths=source_relative \
+    protobuf/exhook.proto
+```
+
+Run server
+```
+go run main.go
+```
