Apache RocketMQ 4.0.0 - linux安装与配置笔记

https://my.oschina.net/langxSpirit/blog/910177

摘要: 官网的Quick Start太简陋,很多坑在里面,这里整理记录一下、

一、安装与配置

1、下载 

官网:http://rocketmq.apache.org/

如:rocketmq-all-4.0.0-incubating-bin-release.zip

需要

64bit OS, Linux/Unix/Mac is recommended;
64bit JDK 1.7+;

2、复制到对应目录,linux中解压

复制rocketmq-all-4.0.0-incubating-bin-release.zip到  /opt/rocketmq

 
mkdir /opt/rocketmq
cd /opt/rocketmq
unzip rocketmq-all-4.0.0-incubating-bin-release.zip 

3、增加执行权限:

cd bin
chmod +x *

4、增加环境变量

vi /etc/profile

使用vi 编辑器,在profile文件的末尾加入如下命令:

export ROCKETMQ_HOME=/opt/rocketmq/apache-rocketmq-all
export PATH=$PATH::$ROCKETMQ_HOME/bin

输入:wq! 保存并退出

使得配置立刻生效:

source /etc/profile

5、创建日志目录

cd /opt/rocketmq && mkdir logs

6、启动Name Server

cd /opt/rocketmq/apache-rocketmq-all/bin 
&& nohup sh mqnamesrv > /opt/rocketmq/logs/mqnamesrv.log  2> /opt/rocketmq/logs/mqnamesrv.log &

7、配置Broker

启动之前,可以适当更改一下runbroker.sh参数

runbroker.sh需要根据内存大小进行适当地调整

JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xgmn1g -XX:PermSize=1g -XgX:MaxPermSize=1g"

本机为虚拟机,就设置小点,1-2g内存,如下:

修改配置文件:conf/2m-noslave/broker-a.properties

样例:

listenPort=10911
namesrvAddr=192.168.62.100:9876
brokerClusterName=DefaultCluster
brokerName=broker-a
brokerId=0
deleteWhen=04
fileReservedTime=72
brokerRole=ASYNC_MASTER
flushDiskType=ASYNC_FLUSH

其中 192.168.62.100 为虚拟机静态ip

8、启动Broker

cd /opt/rocketmq/apache-rocketmq-all/bin 
&& nohup sh mqbroker autoCreateTopicEnable=true 
-c /opt/rocketmq/apache-rocketmq-all/conf/2m-noslave/broker-a.properties 
> /opt/rocketmq/logs/mqbroker.log   2>/opt/rocketmq/logs/mqbroker.log &

autoCreateTopicEnable=true 允许 Broker 自动创建Topic,建议线下开启,线上关闭

9、测试

测试生产者:

cd /opt/rocketmq/apache-rocketmq-all
export NAMESRV_ADDR=localhost:9876
sh /opt/rocketmq/apache-rocketmq-all/bin/tools.sh org.apache.rocketmq.example.quickstart.Producer

测试消费者:

sh /opt/rocketmq/apache-rocketmq-all/bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer

 测试OK。

二、快捷命令

1、查看进程

ps aux | grep java | awk '/broker/rocketmq_nameserver'
ps aux | grep java | awk '/broker/rocketmq_brokerserver'

2、查看日志

tail -f /opt/rocketmq/logs/mqnamesrv.log
tail -f /opt/rocketmq/logs/mqbroker.log

3、关闭Name Server、Broker

cd /opt/rocketmq/apache-rocketmq-all/bin && sh mqshutdown namesrv
cd /opt/rocketmq/apache-rocketmq-all/bin && sh mqshutdown broker

 

三、问题

1、如果消费者、生产者位于不通的网段需要经过防火墙的话,需要开通到broker和nameserver的防火墙端口

lokkit -p 9876:tcp -p 10911:tcp

2、 connect to <192.168.62.100:10909> failed

Rocket默认开启了VIP通道,VIP通道端口为10911-2=10909。若Rocket服务器未启动端口10909,则报connect to <> failed。

解决方式:

1)增加一行代码

producer.setVipChannelEnabled(false);

2)增加对端口10909的防火墙开启。
