使用Docker容器部署rocketmq单机的全过程

查询镜像

docker search rocketmq
name                                 description                                     stars     official   automated
foxiswho/rocketmq                    rocketmq                                        69                   
rocketmqinc/rocketmq                 image repository for apache rocketmq            54                   
styletang/rocketmq-console-ng        rocketmq-console-ng                             37                   
apacherocketmq/rocketmq              docker image for apache rocketmq                21                   
apache/rocketmq     

拉取镜像

docker pull foxiswho/rocketmq:server    #mq-server
...
docker pull foxiswho/rocketmq:broker    #mq-broker
...
docker pull styletang/rocketmq-console-ng   #客户端
...

创建namesrv数据存储路径

mkdir -p /var/local/docker/rocketmq/namesrv/store /var/log/docker/rocketmq/namesrv

构建namesrv容器

docker run -d \
--restart=always \
--name rmqnamesrv \
-p 9876:9876 \
-v /var/log/docker/rocketmq/namesrv:/var/log \
-v /var/local/docker/rocketmq/namesrv/store:/var/store \
-e "max_possible_heap=100000000" \
foxiswho/rocketmq \
sh mqnamesrv

创建broker数据存储路径

mkdir -p /var/local/docker/rocketmq/broker/store /var/log/docker/rocketmq/broker

创建broker配置文件

mkdir -p /etc/docker/rocketmq/conf
touch broker.conf
vi broker.conf

broker.conf 内容如下：

vim /docker/rocketmq/conf/broker.conf
# 所属集群名称，如果节点较多可以配置多个
brokerclustername = defaultcluster
#broker名称，master和slave使用相同的名称，表明他们的主从关系
brokername = broker-a
#0表示master，大于0表示不同的slave
brokerid = 0
#表示几点做消息删除动作，默认是凌晨4点
deletewhen = 04
#在磁盘上保留消息的时长，单位是小时
filereservedtime = 48
#有三个值：sync_master，async_master，slave；同步和异步表示master和slave之间同步数据的机制；
brokerrole = async_master
#刷盘策略，取值为：async_flush，sync_flush表示同步刷盘和异步刷盘；sync_flush消息写入磁盘后才返回成功状态，async_flush不需要；
flushdisktype = async_flush
# 设置broker节点所在服务器的ip地址
brokerip1 = 192.168.1.1  # 注意：改成你的ip地址

构建broker容器

docker run -d \
--restart=always \ 
--name rmqbroker \
--link rmqnamesrv:namesrv \
-p 10911:10911 \
-p 10909:10909 \
-v /var/local/docker/rocketmq/broker/store:/var/store \
-v /var/log/docker/rocketmq/broker:/var/logs \
-v /etc/docker/rocketmq/conf/broker.conf:/etc/rocketmq/conf/broker.conf \
-e "namesrv_addr=namesrv:9876" \
-e "max_possible_heap=200000000" \
foxiswho/rocketmq:broker \
sh mqbroker -c /etc/rocketmq/conf/broker.conf

构建rocketmq-console-ng

docker run -d \
--name rmqconsole \
-p 8180:8080 \
--restart=always \
--link rmqserver:namesrv \
-e "java_opts=-drocketmq.namesrv.addr=namesrv:9876 -dcom.rocketmq.sendmessagewithvipchannel=false" \
-t styletang/rocketmq-console-ng
