rocketmq集群搭建

上一章讲解了rocketmq的消息发送与接收，那么这篇文章讲解如何安装rocketmq

单机搭建

1. 安装包准备

上传apache-rocketmq.tar.gz至/opt目录
http://download.csdn.net/download/xxzblog/10124706

机器ip：192.168.1.101

2. 安装

cd /opttar -xzf apache-rocketmq.tar.gzmv apache-rocketmq rocketmqmkdir /opt/rocketmq/logscd /opt/rocketmq/bin && dos2unix *

3. 环境配置

cp /opt/rocketmq/conf/broker.conf /opt/rocketmq/conf/broker.propertiesecho "brokerIP1=192.168.1.101" > /opt/rocketmq/conf/broker.propertiesvi /opt/rocketmq/mqnamesrv-start.shexport ROCKETMQ_HOME=/opt/rocketmqnohup sh /opt/rocketmq/bin/mqnamesrv > /opt/rocketmq/logs/mqnamesrv.log 2>&1 &:xchmod u+x /opt/rocketmq/mqnamesrv-start.shvi /opt/rocketmq/mqbroker-start.shexport ROCKETMQ_HOME=/opt/rocketmqnohup sh /opt/rocketmq/bin/mqbroker -n 192.168.1.101:9876 -c /opt/rocketmq/conf/broker.properties > /opt/rocketmq/logs/mqbroker.log 2>&1 &:xchmod u+x /opt/rocketmq/mqbroker-start.sh

集群搭建

1, 2同单机一样

本文配置2m-noslave，机器ip：192.168.1.101，192.168.1.102

3.环境配置

/opt/rocketmq/conf/2m-noslave/broker-a.properties

启动nameserver脚本[两台机器]

cd /opt/rocketmq/binnohup sh mqnamesrv &

启动BrokerServer

192.168.1.101

nohup sh /opt/rocketmq/bin/mqbroker -c /opt/rocketmq/conf/2m-noslave/broker-a.properties > /opt/rocketmq/logs/mqbroker.log  2>&1 &

192.168.1.102

nohup sh /opt/rocketmq/bin/mqbroker -c /opt/rocketmq/conf/2m-noslave/broker-b.properties > /opt/rocketmq/logs/mqbroker.log  2>&1 &

备注：可以执行对os的优化/opt/rocketmq/bin/os.sh

rocketmq-console搭建

1.安装包准备

上传rocketmq-console-ng-1.0.0.jar至/opt/rocketmq-console
http://download.csdn.net/download/xxzblog/10124810

2. 启动脚本

vi /opt/rocketmq-console/start.shnohup java -jar rocketmq-console-ng-1.0.0.jar --server.port=12581 --rocketmq.config.namesrvAddr=192.168.1.101:9876,192.168.1.102:9876 >/opt/rocketmq-console/run.log 2>&1 &:xchmod u+x /opt/rocketmq-console/start.sh

3. 执行脚本

/opt/rocketmq-console/start.sh

4. 验证是否成功

浏览器打开:http://127.0.0.1:12581

整个rocketmq搭建就结束了
