RocketMQ(二)

安装

broker默认端口号10911

先在node1上操作：

cd /bin ☆新开一个标签页2☆ cd /opt/rocketmq-4.9.2/bin vi mqbroker vi runbroker.sh 使其值少于4G 注意：我们这是测试环境 生产不要这么玩！ 再次执行，正常运行 启动broker ☆新开一个标签页3☆ 将节点1的rocketmq包发送到节点2上

再在node2上操作

cd /opt/rocketmq-4.7.2/bin ☆新开一个node2标签页☆ cd /opt/rocketmq-4.7.2/bin

将broker注册到node1的nameserver上

返回node1的标签页3

cd ~

默认有两个目录logs、store 生产按照要求来

测试连接
