tomcat7服务器有错误filterstart，并且不启动

Question

我正在尝试在 ubuntu 13.04 的 tomcat7 下运行 solr 4.3.0。请参阅下面的日志 sn-p，这是我尝试通过运行 catalina.sh 启动 tomcat 时得到的。如日志中所示，我收到错误 filterStart。如何解决？

我已在 /etc/tomcat7 的 server.xml 中将默认端口更改为 9999。我无法打开 localhost:9999 或 localhost:9999/solr。

Answer 1

您遇到的问题与 Solr 4.3 中日志记录机制的更改有关。来自Solr Logging 页面：

发生了什么变化

这些版本在 WAR 文件中不包含任何日志记录 jar。它们必须单独提供。这些版本的 Solr 示例包括设置 SLF4J 并绑定到 Apache log4j 库的 jars（在 jetty lib/ext 目录中）。

为什么会改变？

更改了日志记录设置以提高灵活性。对于旧版本，更改您的日志记录机制需要从源代码构建一个特殊目标或对 WAR 文件进行手术。现在任何人都可以通过更改 jar 文件更改为另一种日志记录机制或升级到更新的组件版本。

请看Using the example logging setup in containers other than Jetty 了解配置 Solr Logging 以与 Tomcat 一起正常工作所需的步骤。当我升级到 Solr 4.3 时，我遇到了同样的问题，这更正了它。

Answer 2

我不是 TomCat 专家，但我会说你的 solr4 servlet 的配置有问题
