Rocket MQ docker 安装

1. 创建配置文件目录
   mkdir -p /docker/rocketmq/data/namesrv/logs /docker/rocketmq/data/namesrv/store
   mkdir -p /docker/rocketmq/data/broker/logs /docker/rocketmq/data/broker/store /docker/rocketmq/conf
2. 创建配置文件
   vim /docker/rocketmq/conf/broker.conf

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 = 192.168.8.47

docker run -d \
--restart=always \
--name rmqnamesrv \
-p 9876:9876 \
-v /docker/rocketmq/data/namesrv/logs:/root/logs \
-v /docker/rocketmq/data/namesrv/store:/root/store \
-e "MAX_POSSIBLE_HEAP=100000000" \
rocketmqinc/rocketmq \
sh mqnamesrv

4. 启动broker

docker run -d  \
--restart=always \
--name rmqbroker \
--link rmqnamesrv:namesrv \

-v  /docker/rocketmq/data/broker/logs:/root/logs \
-v  /docker/rocketmq/data/broker/store:/root/store \
-v /docker/rocketmq/conf/broker.conf:/opt/rocketmq-4.4.0/conf/broker.conf \
-e "NAMESRV_ADDR=namesrv:9876" \
-e "MAX_POSSIBLE_HEAP=200000000" \
rocketmqinc/rocketmq \
