如何在 Oracle Linux 中使用 mod_jk 将 Apache Httpd 连接到多个 Tomcat 实例？
How to connect Apache Httpd to multiple Tomcat instances using mod_jk in Oracle Linux?
问：
我正在尝试使用 Oracle Linux R7U9 中的 mod_jk 模块设置 Apache httpd + 多个 Tomcat 实例配置。目的是让 Apache httpd 通过单个外部 IP 地址 （192.168.157.130） 和单个域 （artemis.com） 接收请求，然后将请求处理委托给不同的 Tomcat 实例。 Tomcat 实例包括：
- 演示 - 使用上下文路径 /bar 部署应用的位置
- expo - 使用上下文路径 /foo 部署应用的位置
在类似的情况下，我试图将此处提供的一些解决方案合并到 SO 中。但是，当我尝试访问应用程序 /bar 和 /foo 时，我不断收到以下错误消息。
我的配置中可能缺少什么？我需要安装任何 Apache 组件吗？ 任何帮助将不胜感激。提前致谢。
