Problem Analysis: only the root user can access the port number below 1024 on Suse, and other users cannot access it.

2. Solution 2.1: Modify the Tomcat server. xml configuration file and change the port to 8081 (or other port numbers above 1024 cannot conflict with other Tomcat ports on the local machine)

[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, then use the root user to log on to the server and run the port redirection command: iptables-t nat-a prerouting-p tcp-dport 80-j REDIRECT-to-port 8081.

This means to redirect to port 8081 when accessing port 80, so that we can change it to any port we need.

[root@tomcat57conf]# iptables -t nat -A PREROUTING -p tcp --dport 80 -j REDIRECT --to-port 8081[root@tomcat57conf]# 

2.3 switch to the tomcat account and start the tomcat Service

You can access the service normally:
