Rocketmq两主两从集群部署
环境准备
准备两台服务器或者虚拟机
服务器一：192.***.*.31
服务器二：192.***.*.32
部署模式： 2M-2S-SYNC(两主两从同步写)
相关安装包存储路径：/root/svr/rocketmq
部署
下载安装包
Apache:
https://www.apache.org/dyn/closer.cgi?path=rocketmq/4.2.0/rocketmq-all-4.2.0-bin-release.zip
Github：
https://github.com/apache/rocketmq/
解压
运行： unzip rocketmq-all-4.2.0-bin-release.zip -d /root/svr/rocketmq
配置host(给nameServer用)
命令： vim /etc/hosts
192.***.*.31 rocketmq1
192.***.*.32 rocketmq2配置环境变量：vim /etc/profile
export ROCKETMQ_HOME=/root/svr/rocketmq
export PATH=$PATH::$ROCKETMQ_HOME/bin执行：source /etc/profile

#角色

mkdir /root/svr/rocketmq/data (也要创建store文件夹)
mkdir /root/svr/rocketmq/data/store/commitlog
mkdir /root/svr/rocketmq/data/store/consumequeue
mkdir /root/svr/rocketmq/data/store/index修改日志配置文件
mkdir -p /root/svr/rocketmq/logs
cd /root/svr/rocketmq/conf && sed -i 's#${user.home}#/root/svr/rocketmq#g' *.xml注意logback.*.xml配置文件中${user.home}需要替换自己指定的目录
改参数
unbroker.sh,runserver.sh启动参数默认对jvm的堆内存设置比较大(不改启动不起来)，如果是虚拟机非线上环境需要改下参数，大小可以根据自己机器来决定
默认大小
-Xms8g -Xmx8g -Xmn4g
改为：
JAVA_OPT="${JAVA_OPT} -server -Xms1g -Xmx1g -Xmn512m"复制
scp 到其他服务器
scp -r rocketmq/ root@192.***.*.32:/root/svr/
启动服务
启动Nameserver服务
在 /root/svr/rocketmq/bin目录下执行命令：nohup sh mqnamesrv &
启动BrokerServer
在 /root/svr/rocketmq/bin目录下执行命令：nohup sh mqbroker -c /root/svr/rocketmq/conf/2m-2s-sync/broker-a.properties&
验证是否启动成功
输入命令jps或者查看rocketmq/logs下日志是否输出正常
查看集群监控状态
sh mqadmin clusterlist -n 192.***.*.31:9876
监控

配置namesrv
rocketmq.config.namesrvAddr=192.***.*.31:9876
测试
export NAMESRV_ADDR=rocketmq1:9876
测试发送端
> sh bin/tools.sh org.apache.rocketmq.example.quickstart.Producer
测试消费端
> sh bin/tools.sh org.apache.rocketmq.example.quickstart.Consumer服务停止
在 /root/svr/rocketmq/bin目录下执行命令或者jps查看进程号 kill -9 pid
sh mqshutdown broker
sh mqshutdown namesrv腾讯云开发者
