Installation RocketMQ-4.9.2 on CentOS 7.9

一、Installation RocketMQ-4.9.2 on CentOS 7.9

地址：

• https://rocketmq.apache.org
• https://github.com/apache/rocketmq
• https://archive.apache.org/dist/rocketmq/4.9.2/rocketmq-all-4.9.2-bin-release.zip

 

准备环境

 

二、下载RocketMQ

wget https://archive.apache.org/dist/rocketmq/4.9.2/rocketmq-all-4.9.2-bin-release.zip

安装解压工具

yum install -y unzip zip

解压

unzip rocketmq-all-4.9.2-bin-release.zip -d /opt/

进入文件夹

cd /opt/rocketmq-4.9.2

 

三、配置环境变量

将rocketmq服务加入环境变量

vim /etc/profile
export PATH=$PATH:/opt/rocketmq-4.9.2/bin
# 使配置文件生效
source /etc/profile

 

四、按需修改启动内存

vim runserver.sh

 

vim runbroker.sh

 

vim tools.sh

 

五、创建目录

创建日志目录

mkdir -p /opt/rocketmq-4.9.2/logs

 

六、启动NameServer

cd /opt/rocketmq-4.9.2/bin
nohup sh mqnamesrv > /opt/rocketmq-4.9.2/logs/mqnamesrv.log 2>&1 &

验证是否启动OK：

tail -f /opt/rocketmq-4.9.2/logs/mqnamesrv.log
# 输出
nohup: ignoring input
Java HotSpot(TM) 64-Bit Server VM warning: Using the DefNew young collector with the CMS collector is deprecated and will likely be removed in a future release
Java HotSpot(TM) 64-Bit Server VM warning: UseCMSCompactAtFullCollection is deprecated and will likely be removed in a future release.
Java HotSpot(TM) 64-Bit Server VM warning: MaxNewSize (262144k) is equal to or greater than the entire heap (262144k).  A new max generation size of 262080k will be used.
The Name Server boot success. serializeType=JSON

如果成功启动，能看到类似如下的日志

The Name Server boot success. ...

 

七、启动Broker

/opt/rocketmq-4.9.2/bin
nohup sh mqbroker -n 127.0.0.1:9876 > /opt/rocketmq-4.9.2/logs/mqbroker.log 2>&1 &

验证是否启动OK

tail -f /opt/rocketmq-4.9.2/logs/mqbroker.log
# 输出
nohup: ignoring input
The broker[ecs-65685, 192.168.0.98:10911] boot success. serializeType=JSON and name server is 127.0.0.1:9876

如果启动成功，能看到类似如下的日志：

The broker[itmuchcomdeMacBook-Pro.local, 192.168.43.197:10911] boot success. serializeType=JSON and name server is localhost:9876

 

八、测试

在发送/接收消息之前，需要告诉客户名称服务器的位置。

RocketMQ 提供了多种方法来实现这一点。为了简单起见，使用环境变量NAMESRV_ADDR

# 开启两个端口，都执行以下命令
export NAMESRV_ADDR=localhost:9876

发送消息

# Producer 端口一执行
sh /opt/rocketmq-4.9.2/bin/tools.sh org.apache.rocketmq.example.quickstart.Producer

接收消息

# Consumer 端口二执行
sh /opt/rocketmq-4.9.2/bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer

 

九、安装RocketMQ控制台

1 编译源码方式

前置环境

• 64bit OS, Linux/Unix/Mac is recommended

• 64bit JDK 1.8+

• Maven 3.2.x

2 下载源码

https://github.com/apache/rocketmq-dashboard
git clone https://github.com/apache/rocketmq-dashboard.git

3 在启动之前先修改下端口，默认的8080 已占用，一定要先修改端口，在进行编译。

vim src/main/resources/application.yml

 

4 Maven spring-boot 方式启动

mvn spring-boot:run

5 或者 使用Maven先build成jar包，再java -jar方式启动

mvn clean package -Dmaven.test.skip=true
java -jar target/rocketmq-dashboard-1.0.1-SNAPSHOT.jar

访问控制台：http://IP:8082

 

十、防火墙开启端口

# 关闭防火墙
systemctl stop firewalld

# 开通端口
firewall-cmd --zone=public --add-port=8082/tcp --permanent
firewall-cmd --zone=public --add-port=9876/tcp --permanent
firewall-cmd --zone=public --add-port=10911/tcp --permanent

# 配置立即生效
firewall-cmd --reload

# 重启防火墙生效
systemctl restart firewalld

云主机需配置安全组

在入方向规则，都允许放行

• 8082：RocketMQ 控制台

• 9876：nameserver 中的端口

• 10911：broker 的端口
