【Rocketmq】通过 docker 快速搭建 rocketmq 集群环境

一.单机版

1.Namesrv服务器

a.获取镜像

docker pull rocketmqinc/rocketmq:4.4.0 mkdir -p /opt/rmq

b.启动容器

docker run --name rmqnamesrv -d \ -p 9876:9876 \ --privileged=true \ --restart=always \ -m 1g \ -v /opt/rmq/data/namesrv/logs:/root/logs \ -v /opt/rmq/data/namesrv/store:/root/store \ -e "MAX_POSSIBLE_HEAP=100000000" \ rocketmqinc/rocketmq:4.4.0 sh mqnamesrv

注意:/opt是自己创建的文件夹

2.broker 服务器

a.创建 vim配置文件

mkdir /opt/rmq/config vim /opt/rmq/config/broker.conf brokerClusterName = DefaultCluster brokerName = broker-a brokerId = 0 deleteWhen = 04 fileReservedTime = 48 brokerRole = ASYNC_MASTER flushDiskType = ASYNC_FLUSH brokerIP1 = {本地外网 IP}

b.启动容器

docker run --name rmqbroker -d \ -p 10909:10909 \ -p 10911:10911 \ --privileged=true \ --restart=always \ -m 1g \ -v /opt/rmq/data/broker/logs:/root/logs \ -v /opt/rmq/rocketmq/data/broker/store:/root/store \ -v /opt/rmq/config/broker.conf:/opt/rocketmq-4.4.0/conf/broker.conf \ --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: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.rocketmq 控制台

a.获取镜像

docker pull pangliang/rocketmq-console-ng

b.启动容器

docker run --name rmqconsole -p 10084:8080 -d \ --privileged=true \ --restart=always \ -m 512m \ -e "JAVA_OPTS=-Drocketmq.namesrv.addr={本地外网 IP}:9876 \ -Dcom.rocketmq.sendMessageWithVIPChannel=false \ -Dserver.contextPath=/rmqconsole" \ pangliang/rocketmq-console-ng

注意:server.contextPath 是项目访问路径,需要在端口后面添加,我这里是为了nginx跳转

二、集群搭建(分别在两台主机安装)

1.Namesrv服务器

#分别在两台主机上运行 docker run --name rmqnamesrv -d \ -p 9876:9876 \ --privileged=true \ --restart=always \ -m 1g \ -v /opt/rmq/data/namesrv/logs:/root/logs \ -v /opt/rmq/data/namesrv/store:/root/store \ -e "MAX_POSSIBLE_HEAP=100000000" \ rocketmqinc/rocketmq:4.4.0 sh mqnamesrv

2.broker 服务器

a.创建配置文件

#两台主机上运行 mkdir /opt/rmq/config vim /opt/rmq/config/broker.conf #213主机 brokerClusterName = MscmCluster brokerName = broker-203 brokerId = 0 deleteWhen = 04 fileReservedTime = 48 brokerRole = ASYNC_MASTER flushDiskType = ASYNC_FLUSH brokerIP1=172.16.46.213 brokerIp2=172.16.46.214 #214主机 brokerClusterName = MscmCluster brokerName = broker-204 brokerId = 0 deleteWhen = 04 fileReservedTime = 48 brokerRole = ASYNC_MASTER flushDiskType = ASYNC_FLUSH brokerIP1=172.16.46.213 brokerIp2=172.16.46.214 docker run --name rmqbroker -d \ -p 10909:10909 \ -p 10911:10911 \ --privileged=true \ --restart=always \ -m 1g \ -v /opt/rmq/data/broker/logs:/root/logs \ -v /opt/rmq/rocketmq/data/broker/store:/root/store \ -v /opt/rmq/config/broker.conf:/opt/rocketmq-4.4.0/conf/broker.conf \ --link rmqnamesrv:namesrv \ -e "NAMESRV_ADDR=172.16.46.213:9876;172.16.46.214:9876" \ -e "MAX_POSSIBLE_HEAP=200000000" \ rocketmqinc/rocketmq:4.4.0 sh mqbroker -c /opt/rocketmq-4.4.0/conf/broker.conf
