启动 jpos Q2 服务器时出错：java.net.UnknownHostException

Question

我已经在 linux (centos) 机器上部署了独立的 Q2 服务器。启动 Q2 服务器时，我收到 UnknownHostException。我无法弄清楚 Q2 服务器指的是哪个主机。我在部署文件夹中使用基于 channel_adapter、server_config、qserver_mux 和 txnmgr_config xml 的配置。在我重新启动服务之前，同样的工作。请找到 q2.log 的摘录。

截至@apr 评论，您可以将cfg/pack.xml 中的序言更改为：

<?xml version="1.0" encoding="UTF-8" standalone="no"?>
