RocketMQ下载安装

Linux下使用maven编译安装

环境准备：

各版本要求：

Version	Client	Broker	NameServer
4.0.0-incubating	>=1.7	>=1.8	>=1.8
4.1.0-incubating	>=1.6	>=1.8	>=1.8
4.2.0	>=1.6	>=1.8	>=1.8
4.3.x	>=1.6	>=1.8	>=1.8
4.4.x	>=1.6	>=1.8	>=1.8
4.5.x	>=1.6	>=1.8	>=1.8
4.6.x	>=1.6	>=1.8	>=1.8
4.7.x	>=1.6	>=1.8	>=1.8
4.8.x	>=1.6	>=1.8	>=1.8
4.9.x	>=1.6	>=1.8	>=1.8

01. github上下载源码并上传到服务器

02. 解压缩

unzip rocketmq-master.zip

03. 进入rocketmq主目录编译项目

mvn -Prelease-all -DskipTests clean install -U

编译好的rocketmq在./distribution/target/目录下，全路径为：

04. 启动namesrv

cd到bin/目录下：

启动namesrv：

./mqnamesrv

05. 启动broker

./mqbroker -n 127.0.0.1:9876

-n 表示指定namesrv

测试

使用tools.sh脚本执行测试程序

生产消息

./tools.sh org.apache.rocketmq.example.quickstart.Producer

消费消息

./tools.sh org.apache.rocketmq.example.quickstart.Consumer

控制台rocketmq-console编译安装

链接

github.com/apache/rock…

下载并上传至服务器，解压并进入rocketmq-console目录

执行编译

mvn clean package -Dmaven.test.skip=true

进入target目录，启动并指定namesrv地址：

java -jar rocketmq-console-ng-1.0.1.jar --rocketmq.config.namesrvAddr=127.0.0.1:9876

安装启动常见错误

1. 无法启动Java虚拟机

• 现象：

[root@iZ2ze85s3rq7ziemxzalwbZ bin]# ./mqnamesrv

Invalid initial heap size: -Xms4g

The specified size exceeds the maximum representable size.

Error: Could not create the Java Virtual Machine.

Error: A fatal exception has occurred. Program will exit.

• 原因：rocketmq默认配置初始化内存为4g，大于物理内存
• 解决：修改namesev启动脚本runserver.sh，将配置改小即可，broker启动脚本修改同理：

# JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

2. 启动broker成功但提示：Failed to obtain the host name

• 现象：

[root@iZ2ze85s3rq7ziemxzalwbZ bin]# ./mqbroker -n localhost:9876
22:30:42.307 [main] ERROR RocketmqCommon - Failed to obtain the host name

• 原因：无法解析主机名
• 解决：hosts文件里添加映射即可

3. tools.sh脚本测试报错：connect to null failed

• 现象：

[root@iZ2ze85s3rq7ziemxzalwbZ bin]# ./tools.sh org.apache.rocketmq.example.quickstart.Producer

... 7 more

• 原因：找不到namesrv
• 解决：修改tools.sh，指定namesrv的地址：

export NAMESRV_ADDR=127.0.0.1:9876
