在同一端口上运行多个Tomcat实例

Question

我需要在同一端口上的不同目录名下运行多个tomcat6实例。我将为两个不同的项目安装tomcat6两次。但是如何配置两个实例在同一个端口上运行？

Answer 1

你可以通过使用mod_jk或mod_proxy指导基于应用程序的请求的apache web服务器来实现此目的。 （并获得两个扩展的解释）

要选择要使用的Apache项目的扩展：apache to tomcat: mod_jk vs mod_proxy

Answer 2

它不可能运行两个服务通过单端口服务。每个端口号只能运行一个tomcat。

Answer 3

一次只能有一个进程在某个端口监听。所以你想要做的并不是直接可能的。将请求转发到其他实例或将另一台服务器用作前端（例如Apache）可能会有好运。

Answer 4

是的，你可以。在server.xml中替换：

<Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true"> 
    <!-- SingleSignOn valve, share authentication between web applications 
     Documentation at: /docs/config/valve.html --> 
    <!-- 
    <Valve className="org.apache.catalina.authenticator.SingleSignOn" /> 
    --> 
    <!-- Access log processes all example. 
     Documentation at: /docs/config/valve.html 
     Note: The pattern used is equivalent to using pattern="common" --> 
    <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" 
      prefix="localhost_access_log." suffix=".txt" 
      pattern="%h %l %u %t &quot;%r&quot; %s %b" /> 
</Host> 

通过

<Host name="app1.com" appBase="webappsApp1" unpackWARs="true" autoDeploy="true"> 

    <!-- SingleSignOn valve, share authentication between web applications 
     Documentation at: /docs/config/valve.html --> 
    <!-- 
    <Valve className="org.apache.catalina.authenticator.SingleSignOn" /> 
    --> 

    <!-- Access log processes all example. 
     Documentation at: /docs/config/valve.html 
     Note: The pattern used is equivalent to using pattern="common" --> 
    <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" 
      prefix="localhost_access_log." suffix=".txt" 
      pattern="%h %l %u %t &quot;%r&quot; %s %b" /> 
</Host> 

<Host name="app2.com" appBase="webappsApp2" unpackWARs="true" autoDeploy="true"> 

    <!-- SingleSignOn valve, share authentication between web applications 
     Documentation at: /docs/config/valve.html --> 
    <!-- 
    <Valve className="org.apache.catalina.authenticator.SingleSignOn" /> 
    --> 

    <!-- Access log processes all example. 
     Documentation at: /docs/config/valve.html 
     Note: The pattern used is equivalent to using pattern="common" --> 
    <Valve className="org.apache.catalina.valves.AccessLogValve" directory="logs" 
      prefix="localhost_access_log." suffix=".txt" 
      pattern="%h %l %u %t &quot;%r&quot; %s %b" /> 
</Host> 

在你把应用1，同为webappsApp2目录和App2的战争webappsApp1目录。

在App1和App2的dns区域放置服务器的公共IP地址。

Answer 5

是的，你可以在同一个端口上运行多个tomcat实例（或任何其他对象）。 为此，您需要将多个真实IP绑定到VIP，然后每个RIP可以使用他们自己的一组端口进行收听。

因此，每个tomcat将运行在相同的端口上，但在不同的真实IP地址上运行。

不同实例与不同的上下文中有相同的端口号：
