升级 xwiki（2.5 到 4.4）

Question

我正在使用 XWIKI ENTERPRISE 2.5 并希望将其升级到 4.4 或 4.3（稳定） 我找到了this upgrade documentation for XWiki。按照指南，我备份了WEB-INF中的重要文件。 之后，我将所有文件从新的.war 复制到我的 wiki 目录 (/var/lib/tomcat6/webapps/xwiki)。然后，我将重要文件移回并覆盖了新文件。

当我访问我的 wiki 页面时收到此错误消息：

HTTP Status 404 - type Status report
message description
  The requested resource () is not available.
Apache Tomcat/6.0.28

这是日志文件：

Answer 1

从 4.0-rc-1 升级到 4.4 或 4.5 时，我遇到了同样的问题。我没有重复的 jar，也没有运行多个 XWiki 实例。可能是 infinispan 或 XWiki 的缓存实现中存在问题。

临时解决方法是在 config.xml 中明确允许重复域：

<globalJmxStatistics
     [...]
     allowDuplicateDomains="true" />

Answer 2

当你这么说时

我将所有文件从新的 .war 复制到我的 wiki 目录

您是否将新文件复制到现有目录？您应该从旧版本中删除所有内容并仅使用新版本中的文件，并且仅从备份中复制必要的配置文件。另外请注意，您不应该只复制旧配置，而是将您的自定义设置合并到默认的新配置中。

堆栈跟踪中的根错误：

Caused by: org.infinispan.jmx.JmxDomainConflictException: Domain already registered org.xwiki.infinispan

建议使用重复的 jar。另一种可能发生这种情况的情况是，当您在同一个容器中拥有多个 XWiki 实例时，在这种情况下，您应该编辑 WEB-INF/cache/infinispan/config.xml，并将行 jmxDomain="org.xwiki.infinispan" 替换为唯一值，例如 jmxDomain="org.xwiki.infinispan.wiki1" 和 @ 987654325@ 用于两个实例。
