环境要求

  • 推荐 64 位操作系统:Linux/Unix/Mac
  • 64bit JDK 1.8+
  • Maven 3.2.x
  • Git

下载解压

进入官方下载地址:https://rocketmq.apache.org/dowloading/releases/,选择合适版本

建议选择 binary 版本。

解压到本地:

> unzip rocketmq-all-4.2.0-source-release.zip
> cd rocketmq-all-4.2.0/

启动 Name Server

> nohup sh bin/mqnamesrv &
> tail -f ~/logs/rocketmqlogs/namesrv.log
The Name Server boot success...

启动 Broker

> nohup sh bin/mqbroker -n localhost:9876 -c conf/broker.conf &
> tail -f ~/logs/rocketmqlogs/broker.log
The broker[%s, 172.30.30.233:10911] boot success...

收发消息

执行收发消息操作之前,不许告诉客户端命名服务器的位置。在 RocketMQ 中有多种方法来实现这个目的。这里,我们使用最简单的方法——设置环境变量 NAMESRV_ADDR

> export NAMESRV_ADDR=localhost:9876
> sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer
SendResult [sendStatus=SEND_OK, msgId= ...

> sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer
ConsumeMessageThread_%d Receive New Messages: [MessageExt...

关闭服务器

> sh bin/mqshutdown broker
The mqbroker(36695) is running...
Send shutdown request to mqbroker(36695) OK

> sh bin/mqshutdown namesrv
The mqnamesrv(36664) is running...
Send shutdown request to mqnamesrv(36664) OK

FAQ

connect to 172.17.0.1:10909 failed

启动后,生产者客户端连接 RocketMQ 时报错:

原因:RocketMQ 部署在虚拟机上,内网 ip 为 10.10.30.63,该虚拟机一个 docker0 网卡,ip 为 172.17.0.1。RocketMQ broker 启动时默认使用了 docker0 网卡,生产者客户端无法连接 172.17.0.1,造成以上问题。

解决方案

(1)干掉 docker0 网卡或修改网卡名称

(2)停掉 broker,修改 broker 配置文件,重启 broker。

修改 conf/broker.conf,增加两行来指定启动 broker 的 IP:

namesrvAddr = 10.10.30.63:9876
brokerIP1 = 10.10.30.63

启动时需要指定配置文件

nohup sh bin/mqbroker -n localhost:9876 -c conf/broker.conf &
