成功启动后的WSO2AM奇怪错误

Question

通过将下载的ZIP文件解压缩到WSO2AM，我安装了一个新版本的ZIP 3.2.0。我还建立了两个数据库(db_am和db_shared)，我正在使用文档中描述的文件deployment.toml中的数据库。然后，我只是通过执行wso2server.sh脚本来启动应用程序。它启动得很好，并出现了下面的行，告诉我应用程序已经成功启动。

TID: [-1234] [] [2020-10-26 15:59:14,710]  INFO {org.wso2.carbon.core.internal.StartupFinalizerServiceComponent} - Server           :  WSO2 API Manager-3.2.0

但在那之后，它给了我以下错误：

The last packet sent successfully to the server was 0 milliseconds ago. The driver has not received any packets from the server.

这些行然后无限期地重复。我真的不明白这些错误是从何而来的。

• 前几个错误中的字符串看起来像密码或标记，但是我还没有在配置中的任何地方设置这个字符串。

这些错误从何而来?我如何修复它们，甚至找出是什么导致了它们？

Answer 1

对于数据库问题，请检查数据库服务器是否已启动和运行，数据库信任是否在deployment.toml(用户名、密码、URL、端口)中正确配置，并且您已经像在文档中一样对数据库运行了正确的MySQL脚本。(也不要忘记包括JDBC驱动程序)

例: deployment.toml吐露

[database.shared_db]
type = "mysql"
url = "jdbc:mysql://localhost:3306/shared_db?useSSL=false"
username = "root"
password = "admin"

Answer 2

检查端口9711是否在不同的网络接口上打开，而不是您的端口。您可以通过执行以下命令来验证这一点。

   sudo lsof -i -P -n

如果它对另一个网络接口开放，则关闭该端口，然后再次启动APIM服务器。

否则，您可以更改APIM配置配置新端口。

[[apim.throttling.url_group]]
traffic_manager_urls = ["tcp://<server_ip>:<port>","tcp://<server_ip>:<port>"]
traffic_manager_auth_urls = ["ssl://<server_ip>:<port>","ssl://<server_ip>:<port>"]
type = "failover"

下面给出了一个示例配置。

[[apim.throttling.url_group]]
traffic_manager_urls = ["tcp://localhost:9611","tcp://localhost:9611"]
traffic_manager_auth_urls = ["ssl://localhost:9711","ssl://localhost:9711"]
type = "failover"
