我正在将WSO2 AM 1.10.0运行到同一区域/区域的Amazon EC2节点上。其中一个是管理器节点，另一个是工作节点。
使用membershipScheme = WKA运行它们时，一切正常。尝试membershipScheme = AWS时，两台服务器都正确注册到云，但不互相交互。我验证了axis2.xml中的AWS参数是否正确，并将端口5700-5800打开为ALL。
我的WKA配置如下：
经理节点（WKA）
<parameter name="membershipScheme">wka</parameter>
<parameter name="localMemberPort">5701</parameter>
<parameter name="localMemberHost">ec2-M</parameter>
<groupManagement enable="true">
<applicationDomain name="wso2.apim.domain"
description="APIM group"
agent="org.wso2.carbon.core.clustering.hazelcast.HazelcastGroupManagementAgent"
subDomain="worker"
port="5757"/>
</groupManagement>
<members>
<member>

工作人员节点（WKA）
<parameter name="membershipScheme">wka</parameter>
<parameter name="localMemberPort">5702</parameter>
<parameter name="localMemberHost">ec2-GW</parameter>
<groupManagement enable="true">
<applicationDomain name="wso2.apim.domain"
description="APIM group"
agent="org.wso2.carbon.core.clustering.hazelcast.HazelcastGroupManagementAgent"
subDomain="mgt"

</groupManagement>
<members>
<member>

</member>
<member>

<port>5702</port>
</member>
</members>
在这种模式下，一切正常，在管理员日志中，我看到网关工作人员加入集群：

现在更改为AWS模式：
经理和工作人员节点（AWS）
<parameter name="membershipScheme">aws</parameter>
<parameter name="accessKey">...</parameter>
<parameter name="secretKey">...</parameter>
<parameter name="securityGroup">...</parameter>
<parameter name="region">eu-west-1</parameter>
（保持其他一切不变）

从日志中可以看出，没有工人的迹象。
此外，管理员所做的更改不会被工作人员使用。
在工作节点中：

我使用telnet检查：端口5757,5701和5702可以通过两个节点访问。
为什么两个节点没有通信的任何想法？
根据评论跟进＃1
为两个节点添加了标签
$ aws ec2 create-tags --resources ec2-M ec2-GW --tags Key = component，Value = gateway
使用describe-instances进行验证：
$ aws ec2 describe-instances
...
"Tags": [
{
"Value": "gateway",
"Key": "component"
}
]
...
修改了axis2.xml，用于ec2-M和ec2-GW：
<parameter name="localMemberPort">5701</parameter>
...
<parameter name="accessKey">...</parameter>
<parameter name="secretKey">...</parameter>
<parameter name="securityGroup">...</parameter>
<parameter name="region">eu-west-1</parameter>
<parameter name="tagKey">component</parameter>
<parameter name="tagValue">gateway</parameter>
仍未与节点进行通信
进一步调查后跟进＃2
使用Hazelcast REST API，我注意到在WKA模式下，每个成员都在两个节点的Hazelcast中注册
在经理上，运行http://ec2-M:5701/hazelcast/rest/cluster：
Members [2] {
Member [ec2-M]:5701 this
Member [ec2-GW]:5702
}
在工作人员上，正在运行http://ec2-GW:5702/hazelcast/rest/cluster：
Members [2] {
Member [ec2-M]:5701
Member [ec2-GW]:5702 this
}
在AWS模式下，每个节点只能看到自己。
在经理上，运行http://ec2-M:5701/hazelcast/rest/cluster：
Members [1] {
Member [ec2-M]:5701 this
}
在工作人员上，正在运行http://ec2-GW:5701/hazelcast/rest/cluster：
Members [1] {
Member [ec2-GW]:5701 this
