搭建rocketmq的三主三从遇到的坑

1、机器配置

cat /etc/hosts
192.168.224.128 worker1
192.168.224.129 worker2
192.168.224.130 worker3

2、broker配置

128机器

a-master

#所属集群名字，名字⼀样的节点就在同⼀个集群内
brokerClusterName=rocketmq-cluster
#broker名字，名字⼀样的节点就是⼀组主从节点。
brokerName=broker-a
#brokerid,0就表示是Master，>0的都是表示 Slave
brokerId=0
#nameServer地址，分号分割
namesrvAddr=worker1:9876;worker2:9876;worker3:9876
#是否允许 Broker ⾃动创建Topic，建议线下开启，线上关闭

130机器

#所属集群名字，名字⼀样的节点就在同⼀个集群内
brokerClusterName=rocketmq-cluster
#broker名字，名字⼀样的节点就是⼀组主从节点。
brokerName=broker-a
#brokerid,0就表示是Master，>0的都是表示 Slave
brokerId=1
#nameServer地址，分号分割
namesrvAddr=worker1:9876;worker2:9876;worker3:9876
#是否允许 Broker ⾃动创建Topic，建议线下开启，线上关闭

listenPort=10912

3、启动命令

namesrv启动命令

cd /app/rocketmq/rocketmq-all-4.9.5-bin-release
nohup bin/mqnamesrv &

broker启动命令

nohup bin/mqbroker -c ../128-a.properties >out1.file 2>&1 &
nohup bin/mqbroker -c ../128-b-s.properties >out2.file 2>&1 &


nohup bin/mqbroker -c ../129-b.properties >out1.file 2>&1 &
nohup bin/mqbroker -c ../129-c-s.properties >out2.file 2>&1 &


nohup bin/mqbroker -c ../130-c.properties >out1.file 2>&1 &
nohup bin/mqbroker -c ../130-a-s.properties >out2.file 2>&1 &

4、dashboard配置文件

编译后把配置文件和jar包放同一路径

rocketmq:
  config:
    namesrvAddrs:
      - 192.168.224.128:9876

5、成功

6、坑点

1）同一台机器搭建不同的broker，不同broker的存储文件路径不能相同

2）监听端口

比如有台broker配置了10991，另外一台的监听端口不要配置10992，因为broker默认会启动相邻的端口。启动另外的msgbroker失败提示端口被占用

使用 sudo ss -tlpn | grep ':10992',最后我是间隔了20个端口
