我在阿里云ECS服务器上的服务器上运行的点火服务器（与亚马逊AWS相同），当我检查日志时，我发现了一些警告，似乎服务器尝试连接其他节点与外部IP（ outter ip似乎也是阿里云服务器） 但我的服务器配置了静态IP发现：
<!-- Explicitly configure TCP discovery SPI to provide list of initial nodes. -->
<property name="discoverySpi">
<bean class="org.apache.ignite.spi.discovery.tcp.TcpDiscoverySpi">
<property name="ipFinder">
<!-- Uncomment static IP finder to enable static-based discovery of initial nodes. -->
<bean class="org.apache.ignite.spi.discovery.tcp.ipfinder.vm.TcpDiscoveryVmIpFinder">

<property name="addresses">

<value>172.24.113.216:47500..47509</value>
</list>
</property>

警告日志如下：

172.24.113.216是我的私有子网ip，但在上面的日志中，rmtAddr = / 120.55.13.109：40648和rmtAddr = / 119.23.174.205：56168不是我自己拥有的IP，它是两个公共IP的阿里ECS云（我不知道这两个节点是否与我一起保存私网，因为它不属于我自己），所以，为什么 warinng发生了，警告代表什么，这是不是意味着我的节点尝试连接其他节点，即使我配置了静态发现，似乎我有丢失缓存数据的风险？
答案 0 :(得分：2)
172.24.113.216:11211是用于Memcached [1]和Redis [2]协议实现的服务器端端口。所以它是相反的 - 来自120.55.13.109尝试连接到您的一个节点。
