||
## 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：
|
||
|
||
```sh
|
||
> unzip rocketmq-all-4.2.0-source-release.zip
|
||
> cd rocketmq-all-4.2.0/
|
||
```
|
||
|
||
## 启动 Name Server
|
||
|
||
```sh
|
||
> nohup sh bin/mqnamesrv &
|
||
> tail -f ~/logs/rocketmqlogs/namesrv.log
|
||
The Name Server boot success...
|
||
```
|
||
|
||
## 启动 Broker
|
||
|
||
```sh
|
||
> 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` ：
|
||
|
||
```sh
|
||
> 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
|
||
> 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 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
|
||
|
||
```sh
|
||
nohup sh bin/mqbroker -n localhost:9876 -c conf/broker.conf &
|
||
```
