问题分析：在Suse上只有root用户才可以访问1024以下的端口号，其余用户不能访问。
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。
意思就是当访问80端口时重定向到8081端口，这样，我们可以改成任何我们需要的端口啦。
[root@tomcat57conf]# iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8081[root@tomcat57conf]#

2.3，切换到tomcat账号，启动tomcat服务
就可以正常访问了：

2016-04-16 补充：
执行service iptables save;将修改的iptables信息保存起来，restart会生效，并且加入chkconfig重启生效：
service iptables save; chkconfig --level 2345 iptables on; chkconfig --add iptables;
