无法在centos上启动wso2 API Manager v2.0.0 7.0

Question

我正在尝试WSO2 API Manager 2.0，但无法启动服务器。你想要举手吗？非常感谢Michael

以下是版本信息。

但是，当我开始API管理器“wso2server.sh --start”命令，我发现在wso2carbon.log以下错误信息。

Answer 1

由于Java Preferences子系统无法写入目录/etc/.java/.systemPrefs，可能会发生此警告。你可以验证目录/etc/.java/.systemPrefs是否存在于你的系统中？如果它存在，它是否对运行JVM实例的用户可写？如果不是，请提供许可并重新启动APIM。

如果上述不起作用，您也可以尝试下面的解决方法。

1）在运行JVM的用户可访问的位置创建一个目录，并具有以下子结构。 /.java/.systemPrefs

2）启动WSO2 APIM服务器的Java选项-Djava.util.prefs.systemRoot=<CREATED_DIR>/.java

Answer 2

关于阻塞条件异常

TID: [-1] [] [2016-08-19 17:33:32,455] WARN {org.wso2.carbon.apimgt.gateway.throttling.util.BlockingConditionRetriever} - Failed retrieving Blocking Conditions from remote endpoint: Connection refused. Retrying after 15 seconds... {org.wso2.carbon.apimgt.gateway.throttling.util.BlockingConditionRetriever} 

这仅出现我一个集群部署[X1出版商， x1商店，x1网关管理员，x2网关工作者]。这个问题不会在独立设置中出现。

我已经尝试设置流量管理器（tm）节点并指向网关和发布者节点在tm节点（https://docs.wso2.com/display/CLUSTER44x/Clustering+API+Manager+2.0.0），但是这不能解决问题。

我认为，在应用java系统首选项修复后，您仍然遇到阻止条件警告，但不再是Unix文件锁定异常？
