【问题描述】：

无法启动服务器。未配置服务器实例。 （这是tomcat服务器告诉我的）

做 Apache 和 Tomcat 之间的集成任务我得到了 50%。我的意思是，我在配置后启动并运行了 Apache（因为当我加载浏览器时很好），但是当我启动 Tomcat 时出现错误，如下所示：

我的产品版本是：

Apache 2.2.25 (win32) Tomcat 7.0.47（宽 x86） mod_jk.so 1.2.37

Apache httpd.conf：

LoadModule jk_module "C:\Program Files\Apache Software Foundation\Apache2.2\modules\mod_jk.so" JkWorkersFile "C:\Program Files\apache-tomcat-7.0.47\conf\workers.properties" JkLogFile "C:\Program Files\apache-tomcat-7.0.47\conf\from_apache_mod_jk.log" JkLogLevel 信息 JkLogStampFormat "[%a %b %d %H:%M:%S %Y]" 服务器名称 localhost JkMount /examples ajp13 JkMount /examples/* ajp13

Tomcat server.xml：

【问题讨论】：

server.xml 是： 我的意思是，在寻找配置时，我看到了很多配置它的可能性。我更喜欢 apache 网站内的说明，但 Tomcat 无法加载。有人可以帮我吗？

我找到了这个解释的文件，但是我不明白。如何集成 Tomcat 7 和 Apache 2.2？ faqcluster.com/question1875309190

【参考方案1】：

下载tomcat-jk2.jar 文件，放到Tomcat 的lib 文件夹中。这样就可以解决你的问题了。 可以从here下载tomcat-jk2.jar。

【参考方案2】：

马科斯，

您阅读的那封邮件在 tomcat 用户邮件列表中。他们说ApacheConfig 类已从tomcat7 中删除，因此尝试在server.xml 中使用它配置侦听器会抛出ClassNotFoundException。所以基本上你必须从你的server.xml 中删除Listener 配置。

如果你已经有一个'mod_jk.conf'文件，你必须把它放在Apache配置目录中——我不确定windows，但在linux中有一个'conf.d'或者有一个mods-available 目录（如果放在后者中，需要启用a2enmod 的模块）

如果您无法将其添加到主 Apache 配置文件的底部。

要在配置中添加什么，请查看configuring tomat's server.xml file with auto generating mod_jk.conf
