# RocketMQ 安装部署 - [环境要求](#环境要求) - [下载解压](#下载解压) - [启动 Name Server](#启动-name-server) - [启动 Broker](#启动-broker) - [收发消息](#收发消息) - [关闭服务器](#关闭服务器) - [FAQ](#faq) - [connect to <172.17.0.1:10909> failed](#connect-to-172170110909-failed) - [参考资料](#参考资料) ## 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: ```bash > unzip rocketmq-all-4.2.0-source-release.zip > cd rocketmq-all-4.2.0/ ``` ## 启动 Name Server ```bash > nohup sh bin/mqnamesrv & > tail -f ~/logs/rocketmqlogs/namesrv.log The Name Server boot success... ``` ## 启动 Broker ```bash > 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` : ```bash > 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 ```bash > 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: ```java org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to <172.17.0.1:10909> failed at org.apache.rocketmq.remoting.netty.NettyRemotingClient.invokeSync(NettyRemotingClient.java:357) at org.apache.rocketmq.client.impl.MQClientAPIImpl.sendMessageSync(MQClientAPIImpl.java:343) at org.apache.rocketmq.client.impl.MQClientAPIImpl.sendMessage(MQClientAPIImpl.java:327) at org.apache.rocketmq.client.impl.MQClientAPIImpl.sendMessage(MQClientAPIImpl.java:290) at org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.sendKernelImpl(DefaultMQProducerImpl.java:688) at org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.sendSelectImpl(DefaultMQProducerImpl.java:901) at org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.send(DefaultMQProducerImpl.java:878) at org.apache.rocketmq.client.impl.producer.DefaultMQProducerImpl.send(DefaultMQProducerImpl.java:873) at org.apache.rocketmq.client.producer.DefaultMQProducer.send(DefaultMQProducer.java:369) at com.emrubik.uc.mdm.sync.utils.MdmInit.sendMessage(MdmInit.java:62) at com.emrubik.uc.mdm.sync.utils.MdmInit.main(MdmInit.java:2149) ``` 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 ```bash nohup sh bin/mqbroker -n localhost:9876 -c conf/broker.conf & ``` ## 更多内容 - **引申** - [操作系统、运维部署总结系列](https://github.com/dunwu/OS) - **引用** - [RocketMQ 官方文档](http://rocketmq.apache.org/docs/quick-start/) - [RocketMQ 搭建及刨坑](http://laciagin.me/2017/12/07/RocketMQ%E6%90%AD%E5%BB%BA%E5%8F%8A%E5%88%A8%E5%9D%91/)
