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

Question

我试图让tomcat服务器在其上运行具有多种服务，如此处所述： https ://dzone.com/articles/run-configure-multiple-instance-in-a-single-tomcat

我使用所有需要的目录为服务创建了单独的文件夹，并在原始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上，我得到了：

我的server.xml就像这样：

        <?xml version='1.0' encoding='utf-8'?>
    <Server port="8005" shutdown="SHUTDOWN">
      <Listener className="org.apache.catalina.startup.VersionLoggerListener" />

      <Listener className="org.apache.catalina.core.JasperListener" />
      <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener" />
      <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener" />

Answer 1

从server.xml <Listener className="org.apache.catalina.core.JasperListener" /> 删除行

只需从server.xml中删除过时的设置

仅与Tomcat 7相关
