導讀
上一集我們已經學會了SpringBoot整合RocketMQ點我直達，今天我們來搭建雙主雙從高效能MQ服務叢集。
簡介
主從架構
Broker角色，Master提供讀寫，Slave只支援讀，Consumer不用配置，當Master不可用或者繁忙的時候，Consumer會自動切換到Slave節點進行讀取。雙主雙從，同步複製，非同步刷盤。
叢集配置(4臺機器)
- 兩臺部署Broker-Master和NameServer
- 兩臺部署Broker-Slave和NameServer
前置條件
- Maven
- Git
- Jdk1.8
- RocketMQ 4.7.1
- 4臺機器，ip分別為如下
- 192.168.199.110(主)
- 192.168.199.120(從)
- 192.168.199.130(主)
- 192.168.199.140(從)
搭建
安裝依賴項
上傳相應檔案及安裝目錄
maven編譯
cd /opt/soft/rocketmq-all-4.7.1-source-release
mvn -Prelease-all -DskipTests clean install -U
修改啟動記憶體大小
因為是本地搭建的4臺虛擬機器，只分配的1G，不把啟動記憶體設定小點，服務跑不起來~
修改，110、130
切換
cd /opt/soft/rocketmq-all-4.7.1-source-release/distribution/target/rocketmq-4.7.1/rocketmq-4.7.1/bin
編輯
vim runserver.sh
修改引數
原始：
JAVA_OPT="${JAVA_OPT} -server -Xms4g -Xmx4g -Xmn2g -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
修改為：
JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"
修改，110、120、130、140
切換
cd /opt/soft/rocketmq-all-4.7.1-source-release/distribution/target/rocketmq-4.7.1/rocketmq-4.7.1/bin
編輯
vim runbroker.sh
修改
原始值：
JAVA_OPT="${JAVA_OPT} -server -Xms8g -Xmx8g -Xmn4g"
修改為：
JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m"
