第一，修改tomcat的配置文件：

找到：

    <Connector port="80" maxHttpHeaderSize="8192" 
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" redirectPort="8443" acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true" />

修改为：

    <Connector port="80" maxHttpHeaderSize="8192" address="0.0.0.0"
               maxThreads="150" minSpareThreads="25" maxSpareThreads="75"
               enableLookups="false" redirectPort="8443" acceptCount="100"
               connectionTimeout="20000" disableUploadTimeout="true" />

Tomcat ipv6改成ipv4
