Tomcat灵活配置多项目，多端口，多域名，多虚拟目录

Tomcat的配置都在Tomcat的安装目录的conf文件夹下的server.xml文件

最初内容：（去掉所有注释）

<?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.AprLifecycleListener" SSLEngine="on"/>  
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener"/>  
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener"/>  
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener"/>  
  <GlobalNamingResources> 
    <Resource name="UserDatabase" auth="Container" type="org.apache.catalina.UserDatabase" description="User database that can be updated and saved" 
              factory="org.apache.catalina.users.MemoryUserDatabaseFactory" pathname="conf/tomcat-users.xml"/> 
  </GlobalNamingResources>  
  <Service name="Catalina"> 
    <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443"/>  
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443"/>  
    <Engine name="Catalina" defaultHost="localhost"> 
      <Realm className="org.apache.catalina.realm.LockOutRealm"> 
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> 
      </Realm>  
      <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true"> 
        <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> 
    </Engine> 
  </Service> 
</Server>

默认的是8080端口

1.多个端口指向同一个应用程序

绑定多个Connector

在上面的xml中添加

<Connector port="8020" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443"/>

重新启动Tomcat，如果有服务要重启服务，就会发现也可以用127.0.0.1:8020访问8080的项目

2.配置多个端口，分别指向不同的应用程序

server.xml文件中每个Server都可以配置一个应用程序，可以配置多个Service

在Tomcat安装目录的文件夹下分别创建两个文件夹，名称为webapps1,webapps2,用于存放不同的应用程序

在server.xml中添加配置：

  <Service name="Catalina1"> 
    <Connector port="8021" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443"/>  
    <Engine name="Catalina1" defaultHost="localhost"> 
      <Realm className="org.apache.catalina.realm.LockOutRealm"> 
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> 
      </Realm>  
      <Host name="localhost" appBase="webapps1" unpackWARs="true" autoDeploy="true"> 
        <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> 
    </Engine> 
  </Service>  
  <Service name="Catalina2"> 
    <Connector port="8022" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443"/>  
    <Engine name="Catalina2" defaultHost="localhost"> 
      <Realm className="org.apache.catalina.realm.LockOutRealm"> 
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> 
      </Realm>  
      <Host name="localhost" appBase="webapps2" unpackWARs="true" autoDeploy="true"> 
        <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> 
    </Engine> 
  </Service> 

分别绑定8021,8022端口，分别指向webapp1,webapp2应用程序

完整版：

<?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.AprLifecycleListener" SSLEngine="on"/>  
  <Listener className="org.apache.catalina.core.JreMemoryLeakPreventionListener"/>  
  <Listener className="org.apache.catalina.mbeans.GlobalResourcesLifecycleListener"/>  
  <Listener className="org.apache.catalina.core.ThreadLocalLeakPreventionListener"/>  
  <GlobalNamingResources> 
    <Resource name="UserDatabase" auth="Container" type="org.apache.catalina.UserDatabase" description="User database that can be updated and saved" factory="org.apache.catalina.users.MemoryUserDatabaseFactory" pathname="conf/tomcat-users.xml"/> 
  </GlobalNamingResources>  
  <Service name="Catalina"> 
    <Connector port="8080" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443"/>  
    <Connector port="8020" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443"/>  
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443"/>  
    <Engine name="Catalina" defaultHost="localhost"> 
      <Realm className="org.apache.catalina.realm.LockOutRealm"> 
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> 
      </Realm>  
      <Host name="localhost" appBase="webapps" unpackWARs="true" autoDeploy="true"> 
        <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> 
    </Engine> 
  </Service>  
  <Service name="Catalina1"> 
    <Connector port="8021" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443"/>  
    <Engine name="Catalina1" defaultHost="localhost"> 
      <Realm className="org.apache.catalina.realm.LockOutRealm"> 
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> 
      </Realm>  
      <Host name="localhost" appBase="webapps1" unpackWARs="true" autoDeploy="true"> 
        <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> 
    </Engine> 
  </Service>  
  <Service name="Catalina2"> 
    <Connector port="8022" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443"/>  
    <Engine name="Catalina2" defaultHost="localhost"> 
      <Realm className="org.apache.catalina.realm.LockOutRealm"> 
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> 
      </Realm>  
      <Host name="localhost" appBase="webapps2" unpackWARs="true" autoDeploy="true"> 
        <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> 
    </Engine> 
  </Service> 
</Server>

同样重启Tomcat，或者服务即可。

3.配置多个域名，分别绑定不同的应用程序

修改host的配置

<Service name="Catalina3"> 
  <Connector port="80" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443"/>  
  <Engine name="Catalina3" defaultHost="www.bbb.com"> 
    <Realm className="org.apache.catalina.realm.LockOutRealm"> 
      <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> 
    </Realm>  
    <Host name="www.bbb.com" appBase="webapps2" unpackWARs="true" autoDeploy="true"> 
      <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="www.ddd.com" appBase="webapps2" unpackWARs="true" autoDeploy="true"> 
      <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> 
  </Engine> 
</Service>

这里只是绑定了域名，本机调用的话，必须要修改hosts

4.虚拟目录

Host节点内部可以添加Context

 <Service name="Catalina2">
    <Connector port="8022" protocol="HTTP/1.1"
               connectionTimeout="20000"
               redirectPort="8443" />
    
    <Engine name="Catalina2" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
       
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm"
               resourceName="UserDatabase"/>
      </Realm>
      <Host name="localhost"  appBase="webapps2"
            unpackWARs="true" autoDeploy="true">
        <Context path="" docBase="/test/" debug="0" privileged="true"/>
        <Context path="aa" docBase="/test/" debug="0" privileged="true"/>
        <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>
       
    </Engine>
  </Service>

docBase是虚拟目录的物理路径，可以设置相对路径，也可以设置绝对路径，相对路径是相对应appBase的

分别添加了两个Context,在webapps2文件夹下创建文件夹test,并在内部放入a.html

访问方式：

http://127.0.0.1:8022/test/a.html

http://127.0.0.1:8022/aa/a.html

http://127.0.0.1:8022/a.html

上面分别是3种不同的调用方式，都是调用同一个页面webapps2/test/a.html

5.指向开发项目目录

D:代码GitSpringMVCDemo arget，这个是开发项目打包目录地址

springmvcdemo是项目名称，target文件夹下在打包后会生成springmvcdemo.war包，并自动解压。

<Service name="Catalina2"> 
    <Connector port="8022" protocol="HTTP/1.1" connectionTimeout="20000" redirectPort="8443"/>  
    <Engine name="Catalina2" defaultHost="localhost"> 
      <Realm className="org.apache.catalina.realm.LockOutRealm"> 
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/> 
      </Realm>  
      <Host name="localhost" appBase="D:/代码/Git/SpringMVCDemo/target" unpackWARs="true" autoDeploy="true"> 
        <Context path="" docBase="springmvcdemo" debug="0" privileged="true"/>
        <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> 
    </Engine> 
  </Service> 

http://127.0.0.1:8022/springmvcdemo/admin/users

http://127.0.0.1:8022/admin/users

可以通过上面两个地址进行访问。
