Pomelo daemon usage

Pomelo-daemon provides a daemon service for distributed deployment of pomelo application and collecting RPC logs of servers.

Installation

$ npm install -g pomelo-daemon

Usage

Starting Pomelo Server Cluster

• Deploy codes on all the servers of the server cluster;

• Configure servers.json to right host;

• Add daemon.json configuration file into game-server/config, A sample of daemon.json is shown as follows:

{
  "id": "dh37fgj492je",
  "key": "agarxhqb98rpajloaxn34ga8xrunpagkjwlaw3ruxnpaagl29w4rxn",
  "algorithm": "sha256",
  "user": "pomelo"
}

Note: pomelo-daemon uses hawk to provide authentication between servers.

• Change current directory to game-server;
• Execute the following command in the master server:

pomelo-daemon

• In other servers, execute:

pomelo-daemon --mode=server

Note: You can use nohup to deploy daemon as follows:

nohup pomelo-daemon - mode = server

• Then in the master server run the following command under pomelo-daemon client:

start all

• After all above, the pomelo server cluster is launched.

Collecting RPC Logs

pomelo-daemon provides a pomelo rpc logs collector to synchronize the the rpc logs to mongodb, then it can be analyzed by [pomelo-admin-web] (https://github.com/NetEase/pomelo-admin-web).

• Add mongo.json configuration file into game-server/config, A sample of mongo.json is shown as follows:

{
  "host": "localhost",
  "port": 27017,
  "username": "pomelo",
  "password": "pomelo",
  "database": "test",
  "collection": "cpomelo"
}

• Enable pomelo-daemon rpc logger collecting by setting --pattern parameter to rpc-log:

    pomelo-daemon --mode=server --log - pattern = rpc-log

Note: RPC logs collected here is only used for debugging in development environment, it is not recommended to enable RPC logs in production environemnt.
