1.修改端口
Tomcat默認端口為8080，如果需要同時啟動多個Tomcat服務，就需要修改新的Tomcat服務的端口以防止沖突：
為了同時可以啟動更多的Tomcat服務而讓端口不沖突，約定下改端口的規範：
如果想改為 8081，讓如下3個端口分別+1
如果想改為 8082，讓如下3個端口分別+2

1.1.需要修改的文件：apache-tomcat-6.0.35 8081\conf\server.xml
1.2.需要修改的3個端口分別為：8006,8081,8010

　　2.修改命令窗口標題
2.1.需要修改的文件：D:\tools\apache-tomcat-6.0.35\bin\catalina.bat
2.2.若修改的命令窗口標題為：Tomcat8081

:doStart 
shift 
if not "%OS%" == "Windows_NT" goto noTitle 
if "%TITLE%" == "" set TITLE=Tomcat 
set _EXECJAVA=start "%TITLE%" %_RUNJAVA% 
goto gotTitle 
:noTitle 
set _EXECJAVA=start %_RUNJAVA% 
:gotTitle 
if not ""%1"" == ""-security"" goto execCmd 
shift 
echo Using Security Manager 
set "SECURITY_POLICY_FILE=%CATALINA_BASE%\conf\catalina.policy" 
goto execCmd 
  
:doStop

　　3.擴大啟動內存參數
2.1.需要修改的文件：D:\tools\apache-tomcat-6.0.35\bin\catalina.bat
2.2.在文件頭部添加如下（根據實際情況調整）

set JAVA_OPTS=%JAVA_OPTS% -XX:MaxPermSize=2048m -XX:PermSize=1024m -Xmx4048m -Xms2024m
