Micro MQ

以微服务+MQ构建支持高并发连接的分布式消息服务系统

micro-mq

  • Gateway节点Node通过订阅MQ消息的方式，完成消息在节点间的转发
  • 根据业务场景的需求，需要考虑Node节点消息消费与生产速度的匹配
    • Client间的pub/sub关系比较多，如n个node, 发送m条消息/topic/node，节点消费的需求是n*m条/topic
    • Client端多为pub操作，而系统下发消息较少的情况，节点消费需求则比较低

Gateway编程模型

Features

运行

服务依赖

根据配置选择 conf/conf.toml

  • MQ conf.broker
    • Kafka
  • 服务注册与发现 conf.auth
    • Etcd
    • Consul

启动服务

# 启动Gateway，[-h]帮助查看可选参数
$ cd gateway
$ go run -tags "etcd" main.go

# RPC Auth服务，[-h]帮助查看可选参数
$ cd auth
$ go run -tags "etcd" main.go

备用命令

Protobuf

# 在.proto有import时注意相对的路径
protoc -I=$GOPATH/src:.  --go_out=.  api/proto/define.proto

Kafka

# Start the server
$ bin/zookeeper-server-start.sh config/zookeeper.properties
$ bin/kafka-server-start.sh config/server.properties

# List topic
bin/kafka-topics.sh --list --zookeeper localhost:2181

# Start a consumer
bin/kafka-console-consumer.sh --bootstrap-server localhost:9092 --topic topic --from-beginning

Kafka Manager

# 启动报错，需修改conf/application.conf
kafka-manager.zkhosts="localhost:2181"
