mkdir logs

nohup sh bin/mqnamesrv > logs/namesrv.log 2>&1 &

brokerIP1 = 127.0.0.0
# IP根据自己电脑服务器修改一下，最好不要使用这个,ifconfig就可以查看到自己服务器的IP

nohup sh bin/mqbroker -c conf/broker.conf -n localhost:9876 > logs/broker.log 2>&1 &

./bin/mqshutdown broker
./bin/mqshutdown namesrv

./bin/mqadmin updateTopic -n '127.0.0.0:9876' -c MyCluster -t MyTopic

./bin/mqadmin clusterList -n localhost:9876
