升级xwiki (2.5到4.4)

Question

我正在使用XWIKI Enterprise2.5，想要升级到4.4或4.3 (稳定版)，我发现了this upgrade documentation for XWiki。按照指导，我备份了WEB-INF中的重要文件。在那之后，我将所有文件从新的.war复制到我的维基目录(/var/lib/tomcat6/webapps/xwiki)。然后，我将重要文件移回并覆盖新文件。

当我访问我的wiki页面时，我收到了这个错误消息：

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

以下是日志文件：

Answer 1

当你这么说的时候

我将新.war中的所有文件复制到了我的wiki目录

您是否在现有目录上复制了新文件？您应该删除旧版本中的所有内容，只使用新版本中的文件，并且只从备份中复制必要的配置文件。此外，请注意，您不应该只是复制旧配置，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

建议再买一个罐子。另一种可能发生这种情况的情况是，在同一容器中有多个XWiki实例，在这种情况下，您应该编辑WEB-INF/cache/infinispan/config.xml，并将jmxDomain="org.xwiki.infinispan"行替换为唯一值，如两个实例的jmxDomain="org.xwiki.infinispan.wiki1"和jmxDomain="org.xwiki.infinispan.wiki2"。

Answer 2

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

临时解决方法是在config.xml中显式允许重复的域：

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