Tomcat9 多端口 多项目

1.修改../tomcat/conf/server.xml，原有代码以下：

<?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="Catalina80">
	<Executor name="tomcatThreadPool80" namePrefix="catalina-exec-" maxThreads="1000" maxIdleTime="60000"  minSpareThreads="20"/>
    <Connector port="80" protocol="org.apache.coyote.http11.Http11AprProtocol"

			   maxThreads="30000" minSpareThreads="512" enableLookups="false" acceptCount="35000"
			   connectionTimeout="40000" disableUploadTimeout="true" URIEncoding="UTF-8" useBodyEncodingForURI="true" redirectPort="8443" />
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />
    <Engine name="Catalina80" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
      </Realm>
      <Host name="localhost"  appBase="webapps80" unpackWARs="true" autoDeploy="true">
        
      </Host>
    </Engine>
  </Service>
  
  <Service name="Catalina81">
	<Executor name="tomcatThreadPool81" namePrefix="catalina-exec-" maxThreads="1000" maxIdleTime="60000"  minSpareThreads="20"/>
    <Connector port="81" protocol="org.apache.coyote.http11.Http11AprProtocol"
			   executor="tomcatThreadPool81" compression="on" compressionMinSize="2048" noCompressionUserAgents="gozilla, traviata"

			   maxThreads="30000" minSpareThreads="512" enableLookups="false" acceptCount="35000"
			   connectionTimeout="40000" disableUploadTimeout="true" URIEncoding="UTF-8" useBodyEncodingForURI="true" redirectPort="8443" />
    <Connector port="8019" protocol="AJP/1.3" redirectPort="8443" />
    <Engine name="Catalina81" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
      </Realm>
      <Host name="localhost"  appBase="webapps81" unpackWARs="true" autoDeploy="true">
        
      </Host>
    </Engine>
  </Service>
  
  <Service name="Catalina82">
	<Executor name="tomcatThreadPool82" namePrefix="catalina-exec-" maxThreads="1000" maxIdleTime="60000"  minSpareThreads="20"/>
    <Connector port="82" protocol="org.apache.coyote.http11.Http11AprProtocol"
			   executor="tomcatThreadPool82" compression="on" compressionMinSize="2048" noCompressionUserAgents="gozilla, traviata"
			   compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain,application/json,application/x-javascript"
			   maxThreads="30000" minSpareThreads="512" enableLookups="false" acceptCount="35000"
			   connectionTimeout="40000" disableUploadTimeout="true" URIEncoding="UTF-8" useBodyEncodingForURI="true" redirectPort="8443" />
    <Connector port="8029" protocol="AJP/1.3" redirectPort="8443" />
    <Engine name="Catalina82" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
      </Realm>
      <Host name="localhost"  appBase="webapps82" unpackWARs="true" autoDeploy="true">
        
      </Host>
    </Engine>
  </Service>
  
  <Service name="Catalina83">
	<Executor name="tomcatThreadPool83" namePrefix="catalina-exec-" maxThreads="1000" maxIdleTime="60000"  minSpareThreads="20"/>
    <Connector port="83" protocol="org.apache.coyote.http11.Http11AprProtocol"
			   executor="tomcatThreadPool83" compression="on" compressionMinSize="2048" noCompressionUserAgents="gozilla, traviata"
			   compressableMimeType="text/html,text/xml,text/javascript,text/css,text/plain,application/json,application/x-javascript"
			   maxThreads="30000" minSpareThreads="512" enableLookups="false" acceptCount="35000"
			   connectionTimeout="40000" disableUploadTimeout="true" URIEncoding="UTF-8" useBodyEncodingForURI="true" redirectPort="8443" />
    <Connector port="8039" protocol="AJP/1.3" redirectPort="8443" />
    <Engine name="Catalina83" defaultHost="localhost">
      <Realm className="org.apache.catalina.realm.LockOutRealm">
        <Realm className="org.apache.catalina.realm.UserDatabaseRealm" resourceName="UserDatabase"/>
      </Realm>
      <Host name="localhost"  appBase="webapps83" unpackWARs="true" autoDeploy="true">
        
      </Host>
    </Engine>
  </Service>
  
</Server>

二、建立目录 a. 建立须要部署的目录

../Tomcat9/webapps80/ROOT,../Tomcat9/webapps81/ROOT,../Tomcat9/webapps82/ROOT,../Tomcat9/webapps83/ROOT,并将须要部署的项目拷贝至该目录ROOT下；

b. 建立配置文件目录

../Tomcat/conf/Catalina80/localhost，../Tomcat/conf/Catalina81/localhost，../Tomcat/conf/Catalina82/localhost，../Tomcat/conf/Catalina83/localhost

3.修改项目代码 在我尝试的过程当中发现一个比较容易出错的地方，就是最好修改web.xml和log4j.properties配置文件。 其中web.xml文件，须要添加webAppRootKey，代码以下：

<context-param>
    <param-name>webAppRootKey</param-name>
    <param-value>app1.root</param-value>
  </context-param>

<context-param>
    <param-name>webAppRootKey</param-name>
    <param-value>app2.root</param-value>
  </context-param>

<context-param>
    <param-name>webAppRootKey</param-name>
    <param-value>app3.root</param-value>
  </context-param>

便可完工。``` 这里输入代码
