Problem analysis: Only the root user can access the port number below 1024 on SuSE, and the rest of the users will not be able to access it.

2, Solution 2.1, modify the Tomcat server.xml configuration file, modify the port to 8081 (or more than 1024 port number, cannot conflict with other Tomcat ports on this machine)

[[email protected]]# vim/usr/local/app/apache-tomcat-6.0.37_hechuang_lib/conf/ Server.xml <connector   Port  = "8081"  protocol  =  "http/1.1"  connectiontimeout  = "30000"  maxthreads  = accept Count  = uriencoding  = "UTF-8"  redirectport  = "9 143 "/>  <!--A" Connector "using the shared thread pool-->  

2.2, then use the root user to log on to the server, execute the Port redirection command: iptables-t nat-a prerouting-p tcp–dport 80-j redirect–to-port 8081.

This means that when you access port 80, redirect to Port 8081, so that we can change 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 it normally:
