centos7 安装rocketmq4.7.0以及RocketMQ-Console-Ng控制台

本文主要是介绍centos7 安装rocketmq4.7.0以及RocketMQ-Console-Ng控制台，希望对大家解决编程问题提供一定的参考价值，需要的开发者们随着小编来一起学习吧！

一、前置工作

1.1安装jdk8

1.2安装maven

1.3安装git

二、安装rocketmq

大部分的步骤在官网上面都有显示，链接：http://rocketmq.apache.org/docs/quick-start/

不过需要注意单机情况下，尤其是内存不足的时候有许多的注意事项，下面从头开始安装。

2.1 下载最新版rocketmq 4.7.0,并且解压

mkdir /opt/software/
cd /opt/software/
wget https://archive.apache.org/dist/rocketmq/4.7.0/rocketmq-all-4.7.0-source-release.zip
unzip  rocketmq-all-4.7.0-source-release.zip
cd rocketmq-all-4.7.0-source-release/
mvn -Prelease-all -DskipTests clean install -U

2.2 修改三个sh文件

cd /opt/software/rocketmq-all-4.7.0-source-release/distribution/target/rocketmq-4.7.0/rocketmq-4.7.0
vim bin/runserver.sh
vim bin/runbroker.sh
vim bin/tools.sh

将三个文件中的Xms,Xmx,Xmn三个参数修改为合适的数值

JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

将三个文件27-29行中的JAVA_HOME设置为本机的java路径，并注释下面两行，不然会报java环境错误

[ ! -e "$JAVA_HOME/bin/java" ] && JAVA_HOME=JAVA_HOME=/usr/local/java/
# [ ! -e "$JAVA_HOME/bin/java" ] && JAVA_HOME=/usr/java
# [ ! -e "$JAVA_HOME/bin/java" ] && error_exit "Please set the JAVA_HOME variable in your environment, We need java(x64)!"

修改完毕后保存

三、校验安装

3.1启动mqnamesrv

nohup sh bin/mqnamesrv &
tail -f ~/logs/rocketmqlogs/namesrv.log

出现

  The Name Server boot success...为成功

3.2启动Broker

nohup sh bin/mqbroker -n localhost:9876 &
tail -f ~/logs/rocketmqlogs/broker.log

出现

  The broker[%s, 172.30.30.233:10911] boot success...为成功

如果部署在外网上面，需要公网ip访问的话，最好修改conf/broker.conf，新增

brokerIP1=X.X.X.X（公网IP）

同时启动时采用命令：

nohup sh bin/mqbroker -n <公网ip>:9876 -c conf/broker.conf autoCreateTopicEnable=true &

注意：利用公网部署的时候需要关闭selinux，开放端口9876和10911

3.3 利用rocketmq中的快速启动类校验收发消息

 > export NAMESRV_ADDR=localhost:9876> sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer出现SendResult [sendStatus=SEND_OK, msgId= ...为发送成功> sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer
出现ConsumeMessageThread_%d Receive New Messages: [MessageExt...为消费成功

四、安装可视化控制台

4.1 官方地址：

https://github.com/apache/rocketmq-externals/tree/master/rocketmq-console

4.2 git拉取源码

cd /opt/software
git clone https://github.com/apache/rocketmq-externals.git

4.3 修改配置文件

cd /opt/software/rocketmq-externals/rocketmq-console/src/main/resources
vim application.properties

将rocketmq.config.isVIPChannel设置为false，配置rocketmq.config.namesrvAddr为本机地址:9876,可以选择性修改port或者下一步再命令中指定


server.contextPath=
server.port=7777### SSL setting
#server.ssl.key-store=classpath:rmqcngkeystore.jks
#server.ssl.key-store-password=rocketmq
#server.ssl.keyStoreType=PKCS12
#server.ssl.keyAlias=rmqcngkey#spring.application.index=true
spring.application.name=rocketmq-console
spring.http.encoding.charset=UTF-8
spring.http.encoding.enabled=true
spring.http.encoding.force=true
logging.config=classpath:logback.xml
#if this value is empty,use env value rocketmq.config.namesrvAddr  NAMESRV_ADDR | now, you can set it in ops page.default localhost:9876
rocketmq.config.namesrvAddr=192.168.50.195:9876
#if you use rocketmq version < 3.5.8, rocketmq.config.isVIPChannel should be false.default true
rocketmq.config.isVIPChannel=false
#rocketmq-console's data path:dashboard/monitor
rocketmq.config.dataPath=/tmp/rocketmq-console/data
#set it false if you don't want use dashboard.default true
rocketmq.config.enableDashBoardCollect=true
#set the message track trace topic if you don't want use the default one
rocketmq.config.msgTrackTopicName=
rocketmq.config.ticketKey=ticket#Must create userInfo file: ${rocketmq.config.dataPath}/users.properties if the login is required
rocketmq.config.loginRequired=false

利用maven打包

mvn clean package -Dmaven.test.skip=true

关于打包报错：https://blog.csdn.net/qq_37495786/article/details/102620550

运行jar包，启动项目，这里也可以设置rocketmq.config.namesrvAdd：和port

java -jar rocketmq-console-ng-1.0.1.jar 
#或者加入addr和port
java -jar rocketmq-console-ng-1.0.0.jar --server.port=7777 --rocketmq.config.namesrvAddr=192.168.50.195:9876

需要后台启动加入nohup，启动后的首页如图
