修改server.xml，首先把8080端口改为8081：

    <Connector port="8080" protocol="HTTP/1.1" 
               connectionTimeout="20000" 
               redirectPort="8443" />

此时启动，会报错：

SEVERE: Failed to initialize end point associated with ProtocolHandler ["ajp-bio-8009"]
Throwable occurred: java.net.BindException: The socket name is already in use. <null>:8009
修改server.xml，首先把8009端口改为8010：

    <!-- Define an AJP 1.3 Connector on port 8009 -->
    <Connector port="8009" protocol="AJP/1.3" redirectPort="8443" />

此时启动，会报错：
SEVERE: StandardServer.await: create[localhost:8005]: 
Throwable occurred: java.net.BindException: The socket name is already in use.
修改server.xml，首先把8005端口改为8006：

<Server port="8005" shutdown="SHUTDOWN">

注意：如果在unix下拷贝长xml配置，会自动换行，比如报错：
Throwable occurred: org.xml.sax.SAXParseException: Attribute name "cr" associated with an element type "Context" must be followed by the ‘ = ‘ character.
是因为<Context path="" docBase="F:\code\trunk\mapp\thfund\web\thfund\web" debug="5" reloadable="true" crossContext="true">

到crossContext这里，cr就换行了，下一行是ossContext。
