Tomcat 无法从 [/opt/App1/conf/server.xml] 加载服务器配置

Question

我正在尝试在其上安装 tomcat 服务器运行多项服务，如下所述：https://dzone.com/articles/run-configure-multiple-instance-in-a-single-tomcat

我使用所有需要的目录为我的服务创建了单独的文件夹，并且我在原始 Tomcat 中创建了一个控制器文件夹以控制不同的实例。当我想从控制器运行我的应用程序时，我看到 Tomcat 已启动但没有任何反应。

Using CATALINA_BASE:   /opt/apigateway
Using CATALINA_HOME:   /opt/tomcat
Using CATALINA_TMPDIR: /opt/apigateway/temp
Using JRE_HOME:        /usr/java/latest
Using CLASSPATH:       /opt/tomcat/bin/bootstrap.jar:/opt/tomcat/bin/tomcat-juli.jar
Tomcat started.

在 Catalina.out 我明白了：

我的 server.xml 是这样的：

        <?xml version='1.0' encoding='utf-8'?>
    <Server port="8005" shutdown="SHUTDOWN">

Remove line 来自 server.xml <Listener className="org.apache.catalina.core.JasperListener" />

simply REMOVE obsolete setting from server.xml
