在启动tomcat的时候提示8080端口被占用，后来经过查找发现如下结论： 将oracle与tomcat、jbo等其它占用8080端口的服务器安装在一台机器上，会出现8080端口被占用的错误。 一、首先检查8080端口的使用情况 [root@olivenan root]# lsof -i :8080 -n COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME tlr 1031 oracle 12u IPv4 2013 TCP *:webcache (LISTEN) [root@olivenan root]# lsof -i tcp:8080 -n COMMAND PID USER FD TYPE DEVICE SIZE NODE NAME tlr 1031 oracle 12u IPv4 2013 TCP *:webcache (LISTEN) 发现8080端口被oracle使用，注意lsof命令参数的使用。 [root@olivenan root]# lsof -i udp:8080 -n [root@olivenan root]# lsof -i|grep 8080 [root@olivenan root]# netstat -tln|grep 8080 tcp 0 0 0.0.0.0:8080 0.0.0.0:* LISTEN [root@olivenan root]# 二、解决方法一 查找解决方法 将*.diatchers='(PROTOCOL=TCP) (SERVICE=orclXDB)' 修改为#*.diatchers='(PROTOCOL=TCP) (SERVICE=orclXDB)' [oracle@olivenan d]$ sqlplus "/as sysdba" SQL*Plus: Release 9.2.0.4.0 - Production on Fri Jul 6 10:37:32 2007 Copyright (c) 1982, 2002, Oracle Corporation.
