Maven/Docker快速搭建RocketMQ

[]

①:bin_二进制安装版

1. 环境准备

系统环境：centos7 x64
jdk：jdk-8u171-linux-x64
maven：3.2.x以上的版本均可
4g+ free disk for broker server

2. 下载rocketmq

3. 解压

> unzip rocketmq-all-4.4.0-bin-release.zip
> cd rocketmq-all-4.4.0/

4. 根据内存修改配置(默认需要4g+4g 共8g)

cd bin
vim runserver.sh 
# 找到如下配置
java_opt="${java_opt} -server -xms8g -xmx8g -xmn4g"
# 修改成你可以接受的范围
java_opt="${java_opt} -server -xms512m -xmx521m -xmn256m -xx:metaspacesize=128m -xx:maxmetaspacesize=320m"

vim runbroker.sh
# 找到如下配置
java_opt="${java_opt} -server -xms4g -xmx4g -xmn2g -xx:metaspacesize=128m -xx:maxmetaspacesize=320m"
# 修改成你可以接受的范围
java_opt="${java_opt} -server -xms512m -xmx512m -xmn256m"

4.1. 配置环境变量

vim /etc/profile
# 将如下配置加到最后一行
export namesrv_addr=127.0.0.1:9876
#立即生效环境配置
source /etc/profile

5. 启动 name server

  > nohup sh bin/mqnamesrv &
  #查看日志
  > tail -f ~/logs/rocketmqlogs/namesrv.log
    the name server boot success...

6. 启动 broker

  > nohup sh bin/mqbroker -n 127.0.0.1:9876 &
  #查看日志
  > tail -f ~/logs/rocketmqlogs/broker.log 
    the broker[%s, 127.0.0.1:10911] boot success...

7.测试收发消息 send & receive messages

注意:此处tools.sh默认(-xms1g -xmx1g),内存不够需要再次按runserver.sh/runbroker.sh方式修改
# 修改成你可以接受的范围
vi tools.sh
java_opt="${java_opt} -server -xms256m -xmx256m -xmn128m"

 # 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...

8. 关闭rocketmq服务 shutdown 1.broker --> 2.namesrv

> 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

②:docker版

docker search rocketmq
docker pull foxiswho/rocketmq:server-4.5.1
docker pull foxiswho/rocketmq:broker-4.5.1

下面的就是分步启动nameserver和broker。
1.启动nameserver
docker run -d -p 9876:9876 --name rmqserver  foxiswho/rocketmq:server-4.5.1
2.启动broker：
docker run -d -p 10911:10911 -p 10909:10909
--name rmqbroker --link rmqserver:namesrv
 -e "namesrv_addr=namesrv:9876" -e "java_opts=-duser.home=/opt"
 -e "java_opt_ext=-server -xms128m -xmx128m"
 foxiswho/rocketmq:broker-4.5.1
 
broker容器中默认的配置文件的路径为：`/etc/rocketmq/broker.conf`
可以通过追加-v参数指定本机的配置文件：`-v /conf/broker.conf:/etc/rocketmq/broker.conf`

#查看验证启动成功
docker ps|grep rocketmq

#测试收发
vi tools.sh
java_opt="${java_opt} -server -xms256m -xmx256m -xmn128m"
进入容器内部执行shell
发(生产者): `sh bin/tools.sh org.apache.rocketmq.example.quickstart.producer`
收(消费者): `sh bin/tools.sh org.apache.rocketmq.example.quickstart.consumer`

发送成功则显示:sendresult [sendstatus=send_ok, msgid= ...
消费成功则显示:consumemessagethread_%d receive new messages: [messageext...

③:rocketmq-console 可视化监控服务配置

[]

docker镜像版

mvn clean package -dmaven.test.skip=true docker:build
或
docker pull styletang/rocketmq-console-ng
#运行
docker run -e "java_opts=-drocketmq.namesrv.addr=127.0.0.1:9876 -dcom.rocketmq.sendmessagewithvipchannel=false" -p 8080:8080 -t styletang/rocketmq-console-ng

maven编译普通版

cd /usr/local/rocketmq-externals
git clone https://github.com/apache/rocketmq-externals

#修改配置文件
vi /usr/local/rocketmq/rocketmq-externals/rocketmq-console/src/main/resources/application.properties

# 修改如下相应配置
server.port=8080 //服务端口号
rocketmq.config.namesrvaddr=127.0.0.1:9876 //配置服务地址
rocketmq.config.datapath=/tmp/rocketmq-console/data //mq数据路径，可以自己修改

#使用maven打包

cd /usr/local/rocketmq/rocketmq-externals/rocketmq-console
mvn clean package -dmaven.test.skip=true
或
mvn spring-boot:run

#后台运行
nohup java -jar -xms256m -xmx256m -xmn125m rocketmq-console-ng-1.0.1.jar --server.port=8080 --rocketmq.config.namesrvaddr=127.0.0.1:9876 >rocketmq-console.log 2>&1 &
