通过 docker 快速搭建 rocketmq 环境

1. 安装 Namesrv

拉取镜像

docker pull rocketmqinc/rocketmq:4.4.0`

启动容器

docker run -d -p 9876:9876 -v {RmHome}/data/namesrv/logs:/root/logs -v {RmHome}/data/namesrv/store:/root/store --name rmqnamesrv -e "MAX_POSSIBLE_HEAP=100000000" rocketmqinc/rocketmq:4.4.0 sh mqnamesrv

注意事项:
{RmHome} 要替换成你的宿主机想保存 MQ 的日志与数据的地方，通过 docker 的 -v 参数使用 volume 功能，把你本地的目录映射到容器内的目录上。否则所有数据都默认保存在容器运行时的内存中，重启之后就又回到最初的起点。

{RmHome}的目录结构如下:

.
├── conf
│   └── broker.conf
└── data
    ├── broker
    │   ├── logs
    │   └── store
    └── namesrv
        ├── logs
        └── store

2. 安装 broker 服务器

拉取镜像

与上步是同一个镜像，如果上步完成，此步无需拉取
创建 broker.conf 文件

在 {RmHome}/conf 目录下创建 broker.conf 文件

在 broker.conf 中写入如下内容

brokerClusterName = DefaultCluster
brokerName = broker-a
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH
brokerIP1 = {本地外网 IP}

brokerIP1 要修改成你自己宿主机的 IP

启动容器

docker run -d -p 10911:10911 -p 10909:10909 -v {RmHome}/data/broker/logs:/root/logs -v {RmHome}/rocketmq/data/broker/store:/root/store -v {RmHome}/conf/broker.conf:/opt/rocketmq-4.4.0/conf/broker.conf --name rmqbroker --link rmqnamesrv:namesrv -e "NAMESRV_ADDR=namesrv:9876" -e "MAX_POSSIBLE_HEAP=200000000" rocketmqinc/rocketmq:4.4.0 sh mqbroker -c /opt/rocketmq-4.4.0/conf/broker.conf

docker run -u root -d -p 9876:9876 -v /Users/admin/Documents/software/docker_volume_mapping/rocketmq/data/namesrv/logs:/root/logs -v /Users/admin/Documents/software/docker_volume_mapping/rocketmq/data/namesrv/store:/root/store -v /Users/admin/Documents/software/docker_volume_mapping/rocketmq/conf/broker.conf:/opt/rocketmq-4.4.0/conf/broker.conf --name rmqnamesrv -e "MAX_POSSIBLE_HEAP=100000000" --privileged=true rocketmqinc/rocketmq:4.4.0 sh mqnamesrv

启动broker服务

docker run -u root -d -p 10911:10911 -p 10909:10909 -v /Users/admin/Documents/software/docker_volume_mapping/rocketmq/data/broker/logs:/root/logs -v /Users/admin/Documents/software/docker_volume_mapping/rocketmq/data/broker/store:/root/store -v /Users/admin/Documents/software/docker_volume_mapping/rocketmq/conf/broker.conf:/opt/rocketmq-4.4.0/conf/broker.conf --name rmqbroker --privileged=true --link rmqnamesrv:namesrv -e "NAMESRV_ADDR=namesrv:9876" -e "MAX_POSSIBLE_HEAP=200000000" rocketmqinc/rocketmq:4.4.0 sh mqbroker -c /opt/rocketmq-4.4.0/conf/broker.conf

注意事项

注意: {RmHome} 同上步一样，不再缀述。broker.conf 的文件中的 brokerIP1 是你的 broker 注册到 Namesrv 中的 ip。如果不指定他会默认取容器中的内网 IP。除非你的应用也同时部署在网络相通的容器中，本地或容器外就无法连接 broker 服务了，进而导致类似 RemotingTooMuchRequestException 等各种异常。

3. 安装 rocketmq 控制台

拉取镜像

docker pull pangliang/rocketmq-console-ng

启动容器

docker run -e "JAVA_OPTS=-Drocketmq.namesrv.addr={本地外网 IP}:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false" -p 8080:8080 -t pangliang/rocketmq-console-ng

笔者的命令:

docker run -e "JAVA_OPTS=-Drocketmq.namesrv.addr=192.168.1.2:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false" -p 8080:8080 -t pangliang/rocketmq-console-ng

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

注意：这里因为我们用了docker，所以namesrv.addr需要换成docker容器的ip

查看容器中rmqnamesrv的ip

docker exec -it rmqnamesrv bash
cat /etc/hosts

替换 namesrv.addr 后，启动控制台，访问 {你的IP}:8080

笔者自己的namesr启动命令备份

docker run -u root -d -p 9876:9876 -v /mnt/d/software/docker_mapping/rocketmq_mapping/data/namesrv/logs:/root/logs -v /mnt/d/software/docker_mapping/rocketmq_mapping/data/namesrv/store:/root/store -v /mnt/d/software/docker_mapping/rocketmq_mapping/conf/broker.conf:/opt/rocketmq-4.4.0/conf/broker.conf --name rmqnamesrv -e "MAX_POSSIBLE_HEAP=100000000" --privileged=true rocketmqinc/rocketmq:4.4.0 sh mqnamesrv

笔者自己的Docker启动Broker命令备份:

docker run -u root -d -p 10911:10911 -p 10909:10909 -v /mnt/d/software/docker_mapping/rocketmq_mapping/data/broker/logs:/root/logs -v /mnt/d/software/docker_mapping/rocketmq_mapping/data/broker/store:/root/store -v /mnt/d/software/docker_mapping/rocketmq_mapping/conf/broker.conf:/opt/rocketmq-4.4.0/conf/broker.conf --name rmqbroker --privileged=true --link rmqnamesrv:namesrv -e "NAMESRV_ADDR=namesrv:9876" -e "MAX_POSSIBLE_HEAP=200000000" rocketmqinc/rocketmq:4.4.0 sh mqbroker -c /opt/rocketmq-4.4.0/conf/broker.conf

docker run -d -p 10911:10911 -p 10909:10909 -v /Users/admin/Documents/software/docker_volume_mapping/rocketmq/data/broker/logs:/root/logs -v /Users/admin/Documents/software/docker_volume_mapping/rocketmq/data/broker/store:/root/store -v /Users/admin/Documents/software/docker_volume_mapping/rocketmq/conf/broker.conf:/opt/rocketmq-4.4.0/conf/broker.conf --name rmqbroker --link rmqnamesrv:namesrv -e "NAMESRV_ADDR=namesrv:9876" -e "MAX_POSSIBLE_HEAP=200000000" rocketmqinc/rocketmq:4.4.0 sh mqbroker -c /opt/rocketmq-4.4.0/conf/broker.conf

docker exec --user root -it  a5fe17d55f1c3261b57b7689884d6ae51fd64b88b4cd3fc23c84caaffa19feab /bin/bash
