2，解决方案 2.1，修改Tomcat的server.xml配置文件，将端口修改为8081（或者其他1024以上的端口号，不能与本机上的其它Tomcat端口冲突） [root@tomcat57conf]# vim /usr/local/app/apache-tomcat-6.0.37_hechuang_lib/conf/server.xml <Connector port="8081" protocol="HTTP/1.1" connectionTimeout="30000" maxThreads="2000" acceptCount="2000" URIEncoding="UTF-8" redirectPort="9143" /> <!-- A "Connector" using the shared thread pool--> 2.2，然后使用root用户登录服务器，执行端口重定向命令：iptables -t nat -A PREROUTING -p tcp –dport 80 -j REDIRECT –to-port 8081。
