在Red Hat Enterprise Linux 9上使用Docker快速安装并部署RocketMQ，可以显著简化消息队列系统的搭建过程。以下是详细步骤，包括必要的命令和配置文件示例。
步骤一：安装Docker
-
更新系统软件包
sudo dnf update -y -
安装Docker
sudo dnf install -y dnf-plugins-core sudo dnf config-manager --add-repo=https://download.docker.com/linux/centos/docker-ce.repo sudo dnf install -y docker-ce docker-ce-cli containerd.io -
启动并设置Docker为开机自启动
sudo systemctl start docker sudo systemctl enable docker -
验证Docker安装
sudo docker run hello-world
步骤二：拉取RocketMQ Docker镜像
-
从Docker Hub拉取RocketMQ镜像
sudo docker pull apache/rocketmq:latest
步骤三：启动NameServer和Broker
-
启动NameServer
sudo docker run -d --name rmqnamesrv -p 9876:9876 apache/rocketmq:latest sh mqnamesrv -
启动Broker
创建一个
broker.conf配置文件：brokerClusterName = DefaultCluster brokerName = broker-a brokerId = 0 namesrvAddr = 127.0.0.1:9876 autoCreateTopicEnable = true启动Broker容器：
sudo docker run -d --name rmqbroker -p 10911:10911 -p 10909:10909 --link rmqnamesrv:namesrv -v $(pwd)/broker.conf:/opt/rocketmq-4.7.1/conf/broker.conf apache/rocketmq:latest sh mqbroker -c /opt/rocketmq-4.7.1/conf/broker.conf
步骤四：启动RocketMQ控制台（可选）
-
拉取RocketMQ控制台镜像
sudo docker pull styletang/rocketmq-console-ng -
启动RocketMQ控制台
sudo docker run -d --name rmqconsole -p 8080:8080 --link rmqnamesrv:namesrv styletang/rocketmq-console-ng
