在Red Hat Enterprise Linux 9上使用Docker快速安装并部署

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

1. 更新系统软件包

   sudo dnf update -y

2. 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

3. 启动并设置Docker为开机自启动

   sudo systemctl start docker
   sudo systemctl enable docker

4. 验证Docker安装

   sudo docker run hello-world

步骤二：拉取RocketMQ Docker镜像

1. 从Docker Hub拉取RocketMQ镜像

   sudo docker pull apache/rocketmq:latest

步骤三：启动NameServer和Broker

1. 启动NameServer

   sudo docker run -d --name rmqnamesrv -p 9876:9876 apache/rocketmq:latest sh mqnamesrv

2. 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）

1. 拉取RocketMQ控制台镜像

   sudo docker pull styletang/rocketmq-console-ng

2. 启动RocketMQ控制台

   sudo docker run -d --name rmqconsole -p 8080:8080 --link rmqnamesrv:namesrv styletang/rocketmq-console-ng
