# Setup External Communication Channels
|
|
|
|
SkyWalking has default activated gRPC/HTTP servers in the core module, which serve for both internal communication
|
|
and external data report or query.
|
|
|
|
In some advanced scenarios, such as security requirements, specific gRPC/HTTP servers should be exposed for external
|
|
requests.
|
|
|
|
```yaml
|
|
receiver-sharing-server:
|
|
selector: ${SW_RECEIVER_SHARING_SERVER:default}
|
|
default:
|
|
# For REST server
|
|
restHost: ${SW_RECEIVER_SHARING_REST_HOST:0.0.0.0}
|
|
restPort: ${SW_RECEIVER_SHARING_REST_PORT:0}
|
|
restContextPath: ${SW_RECEIVER_SHARING_REST_CONTEXT_PATH:/}
|
|
restMaxThreads: ${SW_RECEIVER_SHARING_REST_MAX_THREADS:200}
|
|
restIdleTimeOut: ${SW_RECEIVER_SHARING_REST_IDLE_TIMEOUT:30000}
|
|
restAcceptQueueSize: ${SW_RECEIVER_SHARING_REST_QUEUE_SIZE:0}
|
|
httpMaxRequestHeaderSize: ${SW_RECEIVER_SHARING_HTTP_MAX_REQUEST_HEADER_SIZE:8192}
|
|
# For gRPC server
|
|
gRPCHost: ${SW_RECEIVER_GRPC_HOST:0.0.0.0}
|
|
gRPCPort: ${SW_RECEIVER_GRPC_PORT:0}
|
|
maxConcurrentCallsPerConnection: ${SW_RECEIVER_GRPC_MAX_CONCURRENT_CALL:0}
|
|
maxMessageSize: ${SW_RECEIVER_GRPC_MAX_MESSAGE_SIZE:52428800} #50MB
|
|
gRPCThreadPoolSize: ${SW_RECEIVER_GRPC_THREAD_POOL_SIZE:0}
|
|
gRPCSslEnabled: ${SW_RECEIVER_GRPC_SSL_ENABLED:false}
|
|
gRPCSslKeyPath: ${SW_RECEIVER_GRPC_SSL_KEY_PATH:""}
|
|
gRPCSslCertChainPath: ${SW_RECEIVER_GRPC_SSL_CERT_CHAIN_PATH:""}
|
|
gRPCSslTrustedCAsPath: ${SW_RECEIVER_GRPC_SSL_TRUSTED_CAS_PATH:""}
|
|
authentication: ${SW_AUTHENTICATION:""}
|
|
```
|
|
|
|
Set `restPort`(HTTP) and `gRPCPort`(gRPC) to a legal port(greater than 0), would initialize new gRPC/HTTP servers for
|
|
external requests with other relative settings. In this case, `core/gRPC` and `core/rest` could be served for cluster
|
|
internal communication only.
