  • 分布式消息列队RocketMQ部署

    模式: 多Master多Slave模式,异步复制;

           每个 Master 配置一个 Slave,有多对Master-Slave,HA 采用异步复制方式,主备有短暂消息延迟,毫秒级。

           优点:即使磁盘损坏,消息丢失的非常少,且消息实时性不会受影响,因为 Master 宕机后,消费者仍然可以从 Slave 消费,此过程对应用透明。不需要人工干预。性能同多 Master 模式几乎一样。

           缺点:Master 宕机,磁盘损坏情况,会丢失少量消息。

         RocketMQ 网络部署图:

        

    环境准备:CentOS_6.5_x64

    IP                 主机名                    功能

    172.17.34.150    LCB-T-rocketmq_nameserver  nameserver

    172.17.34.151    rocketmq_master01           master01

    172.17.34.152    rocketmq_slave01             slave01        

    172.17.34.153    rocketmq_master02          master02

    172.17.34.154    rocketmq_slave02            slave02

    一、安装jdk,配置环境变量

    二、安装rocketmq

    # tar -zxf alibaba-rocketmq-3.2.6.tar.gz -C /usr/local/

    # cd /usr/local/

    # ln -s /usr/local/alibaba-rocketmq /usr/local/rocketmq

    # cd rocketmq/  

    三、启动路径/usr/local/rocketmq

    1、先启动 NameServer,机器 IP 为:172.17.34.150:9876

       授权:chmod a+x bin/mqnamesrv

       启动:nohup ./bin/mqnamesrv >/var/log/ns.log &

       查看日志:tailf /var/log/ns.log

    2、启动 Master01

        cd /usr/local/rocketmq

        chmod a+x bin/mqbroker

        nohup ./bin/mqbroker -n 172.17.34.150:9876 -c ./conf/2m-2s-async/broker-a.properties >/var/log/mq.log &

        tailf /var/log/ns.log

    3、启动Master02

       chmod a+x bin/mqbroker

       nohup ./bin/mqbroker -n 172.17.34.150:9876 -c ./conf/2m-2s-async/broker-a.properties >/var/log/mq.log &

       tailf /var/log/mq.log

    4、启动 Slave01

        chmod a+x bin/mqbroker

        nohup ./bin/mqbroker -n 172.17.34.150:9876 -c ./conf/2m-2s-async/broker-a-s.properties >/var/log/mq.log &

        tailf /var/log/mq.log

    5、启动 Slave02

       chmod a+x bin/mqbroker

       nohup ./bin/mqbroker -n 172.17.34.150:9876 -c ./conf/2m-2s-async/broker-b-s.properties >/var/log/mq.log &

       tailf /var/log/mq.log

       

    四、查看启动端口

        #netstat -tunpl |grep 9876

        tcp        0      0 :::9876                     :::*                        LISTEN      1303/java

    五、关闭nameserver或broker

        #sh ./mqshutdown

        Useage: mqshutdown broker | namesrv

        #sh mqshutdown broker

        #sh mqshutdown namesrv
