Rocketmq环境配置

修改配置文件 broker.conf

位于$ROCKETMQ_HOME/conf目录下 ，启动的时候可以通过-c参数加载该配置文件

#集群名称，可自定义
brokerClusterName=DefaultCluster
brokerName=broker‐a
brokerId=0
#rocketmq‐name服务地址,多个地址用;分开，不配置默认为localhost:9876
namesrvAddr=192.168.18.130:9876
deleteWhen=04
fileReservedTime=48
#主从角色SYNC_MASTER,ASYNC_MASTER,SLAV
brokerRole=ASYNC_MASTER
flushDiskType=ASYNC_FLUSH
##允许自动创建主题topi
autoCreateTopicEnable=true
#broker监听端口
listenPort=10911
#消息存储根路径
storePathRootDir=/data/rocketmq/store
#日志路径
storePathCommitLog=/data/rocketmq/store/commitlog

• 1.namesrvAddr ： NameServer地址，可以配置多个，用逗号分隔；

• 2.brokerClusterName 所属集群名称，如果节点较多可以配置多个

• 3.brokerName broker名称，master和slave使用相同的名称，表明他们的主从关系

　　4.brokerId 0表示Master，大于0表示不同的slave

　　5.deleteWhen 表示几点做消息删除动作，默认是凌晨4点

　　6.fileReservedTime 在磁盘上保留消息的时长，单位是小时

　　7.brokerRole 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；

　　8.flushDiskTyp 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；

　　9.listenPort 启动监听的端口号

　　10.storePathRootDir 存储消息的根目录

　　11.storePathCommitLog 默认路径${user.home} \store\${commitlog}\${fileName}

内存设置

      修改$ROCKETMQ_HOME/bin/runserver.sh 和$ROCKETMQ_HOME/bin/runbroker.sh中JAVA_OPT关于内存的设置

修改配置文件 broker.conf,配置brokerIP

# 指定broker的ip为主网卡的地址
brokerIP1=192.168.18.130

先启动namesrv ，然后启动broker

启动namesrv

[root@xxx bin]# pwd
/usr/local/rocketmq/rocketmq-all-4.3.2-bin-release/bin
[root@artisan bin]# nohup ./mqnamesrv -n 192.168.18.130:9876&
[1] 15588
[root@xxx bin]# nohup: ignoring input and appending output to ‘nohup.out’
tail -f nohup.out

[root@artisan bin]# jps 查看启动的java进程

启动broker

    在$ROCKETMQ_HOME/bin下执行

nohup ./mqbroker -n 192.168.18.130:9876 -c ../conf/broker.conf autoCreateTopicEnable=true &

    -c 参数 加载配置文件

    在$ROCKETMQ_HOME/bin下执行 nohup ./mqbroker -n 192.168.18.130:9876 -c ../conf/broker.conf autoCreateTopicEnable=true &

    192.168.18.130:9876为nameserver，broker要注册到该namesrv 注册中心
    autoCreateTopicEnable=true(允许创建topic），如果broker.conf配置了autoCreateTopicEnable=true，启动命令中可以省略

查看broker启动配置

    在$ROCKETMQ_HOME/bin下执行 ./mqbroker -m

启动控制台

java -jar rocketmq-console-ng-1.0.0.jar --rocketmq.config.namesrvAddr=127.0.0.1:9876

正常退出 （推荐）

在$ROCKETMQ_HOME/bin 调用mqshutdown 脚本执行

• ./mqshutdown broker 关闭broker
• ./mqshutdown namesrv 关闭namesrv
