檢索具體版本
我就隨便選一個吧，如foxiswho/rocketmq，以下是一個查看當前鏡像所有的版本shell命令：
curl https://registry.hub.docker.com/v1/repositories/foxiswho/rocketmq/tags | tr -d '[\[\]" ]' | tr '}' '\n' | awk -F: -v image='foxiswho/rocketmq' '{if(NR!=NF && $3 != ""){printf("%s:%s\n",image,$3)}}'

啓動NameServer
docker run -d -p 9876:9876 --name rmqserver foxiswho/rocketmq:server-4.5.1
啓動broker
docker run -d -p 10911:10911 -p 10909:10909 --name rmqbroker --link rmqserver:namesrv -e "NAMESRV_ADDR=namesrv:9876" -e "JAVA_OPTS=-Duser.home=/opt" -e "JAVA_OPT_EXT=-server -Xms128m -Xmx128m" foxiswho/rocketmq:broker-4.5.1
Broker容器中默認的配置文件的路徑爲：
/etc/rocketmq/broker.conf
也可以通過-v參數指定本機的配置文件：
docker run -d -p 10911:10911 -p 10909:10909 --name rmqbroker --link rmqserver:namesrv -e "NAMESRV_ADDR=namesrv:9876" -e "JAVA_OPTS=-Duser.home=/opt" -e "JAVA_OPT_EXT=-server -Xms128m -Xmx128m" -v /conf/broker.conf:/etc/rocketmq/broker.conf foxiswho/rocketmq:broker-4.5.1
-
注意事項：
broker.conf的配置內容如下：
brokerClusterName = DefaultCluster brokerName = broker-a brokerId = 0 deleteWhen = 04 fileReservedTime = 48 brokerRole = ASYNC_MASTER flushDiskType = ASYNC_FLUSH在最後一行後面新增
brokerIP1 = 192.168.3.27ip改成你的linux宿主機的ip
安裝 rocketmq console
如果一切正常，NameServer和Broker一會兒就會安裝好，爲了管理上的方便，rocketmq console也是必不可少的工具了，通過上面查詢的方式找到需要啓動的版本，啓動方式如下：
docker run -d --name rmqconsole -p 8180:8080 --link rmqserver:namesrv -e "JAVA_OPTS=-Drocketmq.namesrv.addr=namesrv:9876 -Dcom.rocketmq.sendMessageWithVIPChannel=false" -t styletang/rocketmq-console-ng
然後通過如下命令檢查一下啓動情況：
docker ps|grep rocketmq
結果如下：

其他docker命令：
重啓網絡
systemctl restart network停止、刪除所有docker容器
docker stop $(docker ps -a -q) #停止所有docker容器 docker rm $(docker ps -a -q) #刪除所有
