Question

我已经在Linux实例上创建了一个3节点的Corda网络，并且可以启动和完成网络3个节点之间的流程。但是，当我在同一Linux实例上将第4个节点添加到网络时，现有网络中的任何节点都无法完成第4个节点的流量。

这是现有节点的配置：

myLegalName="O=PartyA,L=Mumbai,C=IN"
p2pAddress="198.136.234.245:10005"
rpcSettings {
    address="localhost:10006"
    adminAddress="localhost:10046"
}
rpcUsers=[
    {
        password=test
        permissions=[
            ALL
        ]
        user=user1
    }
]
dataSourceProperties = {
    dataSourceClassName = "org.postgresql.ds.PGSimpleDataSource"
    "dataSource.url" = "jdbc:postgresql://10.0.0.4:5432/postgres"
    "dataSource.user" = test2
    "dataSource.password" = test2p
}

database = {
    transactionIsolationLevel = READ_COMMITTED
    schema = test2
}

jarDirs = ['/home/ubuntu/java/postgres']
webAddress="198.136.234.245:10007"

Here is the configuration of a newly added node:

myLegalName="O=PartyB,L=Delhi,C=IN"
p2pAddress="198.136.234.245:10014"
rpcSettings {
    address="localhost:10015"
    adminAddress="localhost:10055"
}
rpcUsers=[
    {
        password=test
        permissions=[
            ALL
        ]
        user=user1
    }
]
dataSourceProperties = {
    dataSourceClassName = "org.postgresql.ds.PGSimpleDataSource"
    "dataSource.url" = "jdbc:postgresql://10.0.0.4:5432/postgres"
    "dataSource.user" = test5
    "dataSource.password" = test5p
}

database = {
    transactionIsolationLevel = READ_COMMITTED
    schema = test5
}

jarDirs = ['/home/ubuntu/java/postgres']
webAddress="198.136.234.245:10016"

Here's the message in PartyA's log file:
[INFO ] 2019-07-05T13:27:02,457Z [Node thread-1] flow.[ae2549c0-9bfd-4226-9625-653bc79322b0].initiateSession - Initiating flow session with party O=PartyB, L=Delhi, C=IN. Session id for tracing purposes is SessionId(toLong=5939067804807479907). {}

deployNodes引导网络。简而言之，生成的节点彼此了解，一无所知。在不运行deployNodes的情况下将新节点添加到网络将使原始节点相互通信，但它们将看不到新节点。新节点也将看不到原始节点。

要解决此问题，您可以使用deployNodes重建网络。

或者，您将需要一个网络地图，该网络地图将在节点加入网络时处理身份的分布。可以找到here的实现。
