Linux 搭建單機版RocketMq

 1.下載並解壓

#1.下載rocketmq包
wget http://mirrors.tuna.tsinghua.edu.cn/apache/rocketmq/4.6.0/rocketmq-all-4.6.0-bin-release.zip

#2.解壓
unzip rocketmq-all-4.6.0-bin-release.zip

#3.改個名
mv rocketmq-all-4.6.0-bin-release rocketmq

2.修改broker和nameserver的 啓動配置；

#1.修改runbroker.sh(因爲默認是8G，虛擬機我只給了1G運行內存)
vim /usr/local/rocketmq/bin/runbroker.sh

#2.修改runbroker.sh(因爲默認是4G，虛擬機我只給了1G運行內存)
vim /usr/local/rocketmq/bin/runserver.sh

 修改如下：

runserver.sh:(修改對應行)

JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m -XX:MetaspaceSize=128m -XX:MaxMetaspaceSize=320m"

runbroker.sh:(修改對應行) 

JAVA_OPT="${JAVA_OPT} -server -Xms512m -Xmx512m -Xmn256m"

 3.啓動namesrv和broker

[root@localhost bin]# ps -ef | grep rocketmq

4.rocketmq可視化控制檯

rocketmq默認不帶可視化控制檯，需要去單獨編譯一個工具 https://github.com/apache/rocketmq-externals

ps:我的並未打成jar包部署運行，而是直接用IDEA啓動運行。這裏需要改動application.properties配置文件中的rocketmq.config.namesrvAddr的值，改成自己rocketmq部署服務器的ip地址。至於server.port可改可不改。

ps:啓動運行後，訪問http://localhost:8889/#/，結果控制檯報錯：org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to <172.17.0.1:10909> failed

[2020-01-20 11:05:21.656]  INFO closeChannel: close the connection to remote address[192.168.87.135:9876] result: true
[2020-01-20 11:05:22.655] ERROR Unexpected error occurred in scheduled task.
java.lang.RuntimeException: org.apache.rocketmq.remoting.exception.RemotingConnectException: connect to <172.17.0.1:10909> failed
	at com.google.common.base.Throwables.propagate(Throwables.java:160)
	at org.apache.rocketmq.console.task.DashboardCollectTask.fetchBrokerRuntimeStats(DashboardCollectTask.java:219)

解決辦法：

1.關閉broker和namesrv

#關閉broker
sh bin/mqshutdown broker
#
The mqbroker(36695) is running...
Send shutdown request to mqbroker(36695) OK

#關閉namesrv
sh bin/mqshutdown namesrv
The mqnamesrv(36664) is running...
Send shutdown request to mqnamesrv(36664) OK

2.vim broker.conf：

brokerClusterName = DefaultCluster
brokerName = broker-a
brokerId = 0
deleteWhen = 04
fileReservedTime = 48
brokerRole = ASYNC_MASTER
flushDiskType = ASYNC_FLUSH

#增加部分
namesrvAddr=127.0.0.1:9876
brokerIP1=192.168.87.135

3.重新啓動namesrv和broker

> nohup sh bin/mqnamesrv &
> tail -f ~/logs/rocketmqlogs/namesrv.log
  The Name Server boot success...

> nohup sh bin/mqbroker -n localhost:9876 &
> tail -f ~/logs/rocketmqlogs/broker.log 
  The broker[%s, 172.30.30.233:10911] boot success...

再次訪問http://localhost:8889/#/，控制檯無上述錯誤輸出。
