RocketMQ4.7.1双主双从集群搭建
导读
上一集我们已经学会了SpringBoot整合RocketMQ点我直达，今天我们来搭建双主双从高性能MQ服务集群。
简介
主从架构
Broker角色，Master提供读写，Slave只支持读，Consumer不用配置，当Master不可用或者繁忙的时候，Consumer会自动切换到Slave节点进行读取。双主双从，同步复制，异步刷盘。
集群配置(4台机器)
- 两台部署Broker-Master和NameServer
- 两台部署Broker-Slave和NameServer
前置条件
- Maven
- Git
- Jdk1.8
- RocketMQ 4.7.1
- 4台机器，ip分别为如下
- 192.168.199.110(主)
- 192.168.199.120(从)
- 192.168.199.130(主)
- 192.168.199.140(从)
搭建
安装依赖项
上传相应文件及安装目录
maven编译
cd /opt/soft/rocketmq-all-4.7.1-source-release
mvn -Prelease-all -DskipTests clean install -U
修改启动内存大小
因为是本地搭建的4台虚拟机，只分配的1G，不把启动内存设置小点，服务跑不起来~
修改，110、130
切换
cd /opt/soft/rocketmq-all-4.7.1-source-release/distribution/target/rocketmq-4.7.1/rocketmq-4.7.1/bin
编辑
vim runserver.sh
修改参数
原始：
JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
修改为：
JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
修改，110、120、130、140
切换
cd /opt/soft/rocketmq-all-4.7.1-source-release/distribution/target/rocketmq-4.7.1/rocketmq-4.7.1/bin
编辑
vim runbroker.sh
修改
原始值：
JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g"
修改为：
JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m"
启动，110，130
切换
cd /opt/soft/rocketmq-all-4.7.1-source-release/distribution/target/rocketmq-4.7.1/rocketmq-4.7.1
