WSO2 DAS +带有MySQL的集群APIM [英] WSO2 DAS + Clustering APIM with mysql

问题描述

1. 我的APIM版本是1.10.0，DAS是3.0.1.

1. My APIM version is 1.10.0 and DAS is 3.0.1.

首先，我没有使用MySQL部署Clustering APIM + DAS.统计数据显示良好.

At first ,I deploy no Clustering APIM + DAS with mysql. the stats shows good.

然后，我将APIM分为发布者，商店，密钥管理器和网关.已配置的APIM和DAS顺序

Then,I clustering APIM into publisher、store、keymanager and gateway.Configured APIM and DAS order this article,when I invoke an api , gateway node then show error

1. 然后，我更改DAS配置的方式.跟随此博客之后，我配置了所有api-manager.xml，没有错误，也没有统计信息.商店节点显示信息:

1. Then i change the way of DAS configuration. Following this blog ,i configured all the api-manager.xml,there is no error and no stats.And store node show info:

[2016-10-18 11:31:39,131]  INFO - ReceiverGroup Resending the failed published data...
[2016-10-18 11:31:44,134]  WARN - AccessConfiguration Error loading properties from file: access-log.properties
[2016-10-18 11:31:44,207]  INFO - TimeoutHandler This engine will expire all callbacks after : 120 seconds, irrespective of the timeout

1. 我在 wso2吉拉中搜索了原因，他们说这不是错误

1. I google the reason ,in wso2 jira,they say this is not a bug.

但是我不能等待数小时的统计信息.我配置有误吗?

But I cannot wait for my stats for hours.Did I configure something wrong?

推荐答案

似乎在商店节点中，数据正在发布且已启用.但是网关节点数据无法发布.请尝试验证网关节点配置.同时检查网关节点是否可以访问DAS节点.

Seems in store node, data are publishing are enabled and working. But gateway node data not publishing. Please try to verify the gateway node configuration. Also check gateway node can access the DAS node.
