RocketMQ-主从集群模式搭建

1.进入到192.168.80.188服务器(主节点)里面

vi /etc/hosts
192.168.80.188 rocketmq-nameserver1
192.168.80.188 rocketmq-master1
192.168.80.189 rocketmq-nameserver2
192.168.80.189 rocketmq-master-slave

2.进入到192.168.80.189服务器(从节点)里面

vi /etc/hosts
192.168.80.188 rocketmq-nameserver1
192.168.80.188 rocketmq-master1
192.168.80.189 rocketmq-nameserver2
192.168.80.189 rocketmq-master-slave

新建目录

mkdir /usr/local/software

将apache-rocketmq.tar.gz放在此目录下,然后再重新创建一个目录并解压

mkdir /usr/local/apache-rocketmq && tar -zxvf /usr/local/software/apache-rocketmq.tar.gz -C /usr/local/apache-rocketmq

建立一个软连接

[root@localhost local]# ln -s apache-rocketmq rocketmq

创建存储路径

[root@localhost local]# mkdir /usr/local/rocketmq/store
[root@localhost local]# mkdir /usr/local/rocketmq/store/commitlog
[root@localhost local]# mkdir /usr/local/rocketmq/store/consumequeue
[root@localhost local]# mkdir /usr/local/rocketmq/store/index

修改日志文件

mkdir -p /usr/local/rocketmq/logs
cd /usr/local/rocketmq/conf && sed -i 's#${user.home}#/usr/local/rocketmq#g' *.xml

修改脚本参数
vi /usr/local/rocketmq/bin/runbroker.sh

#==============================================================================
#   开发环境 JVM Configuration 
#============================================================================== 
JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn1g"

vi /usr/local/rocketmq/bin/runserver.sh

JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn1g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

3.进入到192.168.80.188服务器(主节点)里面

修改broker-a.properties

vi /usr/local/rocketmq/conf/2m-2s-async/broker-a.properties

#nameServer 地址，分号分割
namesrvAddr=rocketmq-nameserver1:9876;rocketmq-nameserver2:9876

修改broker-a-s.properties

vi /usr/local/rocketmq/conf/2m-2s-async/broker-a-s.properties

#所属集群
brokerClusterName=rocketmq-cluster
#broker 名字，注意此处不同的配置文件填写的不一样
brokerName=broker-a
#0 表示 Master，>0 表示 Slave
brokerId=1
#nameServer 地址，分号分割
namesrvAddr=rocketmq-nameserver1:9876;rocketmq-nameserver2:9876
#在发送消息时，自动创建服务器不存在的 topic，默认创建的队列数
defaultTopicQueueNums=4
#是否允许 Broker 自动创建 Topic，建议线下开启，线上关闭
autoCreateTopicEnable=true
#是否允许 Broker 自动创建订阅组，建议线下开启，线上关闭
autoCreateSubscriptionGroup=true
#Broker 对外服务的监听端口
listenPort=10911
#删除文件时间点，默认凌晨 4 点
deleteWhen=04
#文件保留时间，默认 48 小时

#限制的消息大小
maxMessageSize=65536

#flushCommitLogLeastPages=4
#flushConsumeQueueLeastPages=2
#flushCommitLogThoroughInterval=10000
#flushConsumeQueueThoroughInterval=60000

#Broker 的角色
#- ASYNC_MASTER 异步复制 Master
#- SYNC_MASTER  同步双写 Master
#- SLAVE
brokerRole=SLAVE

#刷盘方式
#- ASYNC_FLUSH  异步刷盘

flushDiskType=ASYNC_FLUSH

#checkTransactionMessageEnable=false
#发消息线程池数量

配置完之后同步到192.168.80.189服务器上

[root@localhost 2m-2s-async]# scp broker-a.properties broker-a-s.properties 192.168.80.189:/usr/local/rocketmq/conf/2m-2s-async/

4.启动

192.168.80.188(主节点):

• 启动nameserver

cd /usr/local/rocketmq/bin
nohup sh mqnamesrv &

• 启动broker

cd /usr/rocketmq/bin
nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-2s-async/broker-a.properties >/dev/null 2>&1&

192.168.80.189(从节点):

• 启动nameserver

cd /usr/local/rocketmq/bin
nohup sh mqnamesrv &

• 启动broker

cd /usr/rocketmq/bin
nohup sh mqbroker -c /usr/local/rocketmq/conf/2m-2s-async/broker-a-s.properties >/dev/null 2>&1&
