activemq cluster masterslave 配置

Activemq集群主备简单配置,基于5.13.3

Master-slave 基于zk的方式

修改activemq.xml

<brokerxmlns="http://activemq.apache.org/schema/core" brokerName="<span style="color:#ff0000;">broker-a</span>"dataDirectory="${activemq.data}">

<replicatedLevelDB
directory="activemq-data"
replicas="3"
bind="tcp://0.0.0.0:0"
zkAddress="your address"
zkPath="/activemq/leveldb-stores"
hostname="localhost "
sync=”local_disk”
/>

<transportConnector name="openwire"uri="tcp://${ip}:61616?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>

${ip} 应该是机器的实际ip地址，使用127.0.0.1或者localhost，则导致client无法连接.

修改jetty.xml，修改端口号为不同的(e.g. 8161, 8161,8163)

 

然后启动

./activemq start (后台进程)

./activemq stop

 

基于上述配置，创建2个slave的目录，

brokerName一致才会认为是一个cluster，且至少有3个才会成功，否则无法选主，导致没有broker可以提供服务

测试master-slave：

Uri="failover:(tcp://ip1:61616,tcp://ip2:61617,tcp://ip3:61618)"

消息发送，默认到ip1上，查看ip1的admin后台，有消息(此时ip1为master)

停止ip1的服务，继续发送，查看ip2的admin后台，有新消息达到(此时ip2为master)

启动ip1的服务，可以看到变成slave



配置cluster：

和上面的配置类似，brokerName变成broker-b，tcp的端口进行变更

剩余其他的transportConnector，对应的端口号，每组broker可以一致，但是不同的broker要不同(我是同一台机器)

启动broker-a 和 broker-b

可以看到2个broker直接建立链接的log

 | Network connection between vm://broker-a#6 and tcp://{ip}:61716 (broker-b) has been established.

 INFO  | Network connection between vm://broker-b#0 and tcp://{ip}:61616 (broker-a) has been established.

最终broker-a的配置

<networkConnectors>
<!-- 连接broker-b -->
<networkConnector uri="masterslave:(tcp://${ip}:61716,tcp:// ${ip}:61717,tcp:// ${ip}:61718)"/>
</networkConnectors>
<persistenceAdapter>
<replicatedLevelDB
directory="activemq-data"
replicas="3"
bind="tcp://0.0.0.0:0"
zkAddress="${ip}:2181"
zkPath="/activemq/leveldb-stores"
hostname="localhost"
sync="local_disk"
/>
</persistenceAdapter>

<transportConnectors>
<!-- DOS protection, limit concurrent connections to 1000 and frame size to 100MB -->
<!-- 示例用的tcp,每个机器的端口要不同-->
<transportConnector name="openwire" uri="tcp://${hostIp}:61616?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
<transportConnector name="amqp" uri="amqp://0.0.0.0:5672?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
<transportConnector name="stomp" uri="stomp://0.0.0.0:61613?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
<transportConnector name="mqtt" uri="mqtt://0.0.0.0:1883?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
<transportConnector name="ws" uri="ws://0.0.0.0:61614?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
</transportConnectors>

broker-b的配置

<networkConnectors>
<!-- 连接broker-a -->
<networkConnector uri="masterslave:(tcp://${ip}:61616,tcp:// ${ip}:61617,tcp:// ${ip}:61618)"/>
</networkConnectors>
<persistenceAdapter>
<replicatedLevelDB
directory="activemq-data"
replicas="3"
bind="tcp://0.0.0.0:0"
zkAddress="${ip}:2181"
zkPath="/activemq/leveldb-stores"
hostname="localhost"
sync="local_disk"
/>
</persistenceAdapter>

<transportConnectors>
<!-- DOS protection, limit concurrent connections to 1000 and frame size to 100MB -->
<!-- 示例用的tcp,每个机器的端口要不同-->
<transportConnector name="openwire" uri="tcp://${hostIp}:61716?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
<transportConnector name="amqp" uri="amqp://0.0.0.0:5672?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
<transportConnector name="stomp" uri="stomp://0.0.0.0:61613?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
<transportConnector name="mqtt" uri="mqtt://0.0.0.0:1883?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
<transportConnector name="ws" uri="ws://0.0.0.0:61614?maximumConnections=1000&wireFormat.maxFrameSize=104857600"/>
</transportConnectors>

测试cluster

Uri="failover:(tcp://ip1:61616,tcp://ip2:61617,tcp://ip3:61618,tcp://ip4:61716,tcp://ip5:61717,tcp://ip6:61718)"

1.启动Java的consumer client，看log连到了broker-a，即前3个ip的集群

从broker-a的后台给queue发消息(10个)，client可以接收到

从broker-b的后台给queue发消息(5个)，client也可以接收到(broker-a会从broker-b把消息拉过来)

此时broker-a的queue上有15个消息，broker-b上有5个消息

2.启动2个consumer，分别连到broker-a 和 broker-b，向不同的broker发消息，对应的consumer可以接收到，向某一个broker发多个消息，两个consumer均能收到消息

 

看log，urlList和上面的uri顺序是不一致的，然后按顺序连接
